Monkeypatching attributes of a class to do testing is an anti-pattern. Prefer dependency-injecting things into classes. That way, at unit test time, you can pass a mocked dependency in

Do not put names of customers or customer company names in code, PRs, and issues. The codebase is public
|
||||
Do not put names of customers or customer company names in code, PR descriptions, issue bodies, etc. This means never mention literally any company name. Especially if you're about to say a sentence mentioning that the reason the PR exists was a feature/model/bug fix/etc. requested by a company. That's the indication that you should replace that company name with "the customer". e.g. not "Model request from Acme (Pylon #1234)" but "Model request from a customer (Pylon #1234)". This is because the codebase is public. The only exception is for publicly known providers or vendors such as OpenAI, Anthropic, AWS Bedrock, etc. only IF we're adding support for that provider/vendor in general and NOT if that PR or whatnot was a request by one of them, and they're actually one of our customers.

CI supply-chain safety: Never pipe a remote script into a shell (`curl ... | bash`, `wget ... | sh`); download the artifact to a file, verify its SHA-256 checksum, then install. Pin every external tool to a specific version with a full URL (not `latest` or `stable`). Verify checksums for all downloaded binaries, using the provider's official `.sha256` / `.sha256sum` sidecar when available. These rules apply to every download in CI

# XecGuard
|
||||
|
||||
Use [XecGuard](https://www.cycraft.com/) (CyCraft) to protect your LLM applications with multi-policy scanning (prompt injection, harmful content, PII, system-prompt enforcement, skills protection) and RAG context grounding validation. XecGuard is a cloud-hosted AI security gateway — there are no self-hosting requirements.
|
||||
|
||||
## Quick Start
|
||||
|
||||
### 1. Define Guardrails on your LiteLLM config.yaml
|
||||
|
||||
```yaml showLineNumbers title="config.yaml"
|
||||
model_list:
|
||||
- model_name: gpt-4
|
||||
litellm_params:
|
||||
model: openai/gpt-4
|
||||
api_key: os.environ/OPENAI_API_KEY
|
||||
|
||||
guardrails:
|
||||
- guardrail_name: "xecguard-guard"
|
||||
litellm_params:
|
||||
guardrail: xecguard
|
||||
mode: "pre_call"
|
||||
api_key: os.environ/XECGUARD_API_KEY
|
||||
api_base: os.environ/XECGUARD_API_BASE # Optional
|
||||
policy_names: # Optional — defaults to System Prompt Enforcement + Harmful Content Protection
|
||||
- Default_Policy_SystemPromptEnforcement
|
||||
- Default_Policy_HarmfulContentProtection
|
||||
```
|
||||
|
||||
#### Supported values for `mode`
|
||||
|
||||
- `pre_call` — Run **before** the LLM call to validate **user input**
|
||||
- `post_call` — Run **after** the LLM call to validate **model output** (also runs context grounding when RAG documents are provided)
|
||||
- `during_call` — Run **in parallel** with the LLM call for input validation
|
||||
- `logging_only` — Run as an **observe-only** callback; records scan decisions without blocking
|
||||
|
||||
### 2. Set Environment Variables
|
||||
|
||||
```shell
|
||||
export XECGUARD_API_KEY="xgs_<your-service-token>"
|
||||
export XECGUARD_API_BASE="https://api-xecguard.cycraft.ai" # Optional, this is the default
|
||||
export XECGUARD_BLOCK_ON_ERROR="true" # Optional, fail-closed by default
|
||||
```
|
||||
|
||||
### 3. Start LiteLLM Gateway
|
||||
|
||||
```shell
|
||||
litellm --config config.yaml --detailed_debug
|
||||
```
|
||||
|
||||

|
||||
- guardrail_name: "xecguard-guard"
|
||||
litellm_params:
|
||||
guardrail: xecguard
|
||||
mode: "pre_call"
|
||||
api_key: os.environ/XECGUARD_API_KEY
|

|
||||
default_on: true # Optional
|
||||
```
|
||||
|
||||
### Required
|
||||
|
||||
| Parameter | Description |
|
||||
|-----------|-------------|
|
||||
| `api_key` | XecGuard **Service Token** (prefix `xgs_`). Falls back to `XECGUARD_API_KEY` env var. |
|
||||
|
||||
### Optional
|
||||
|
||||
| Parameter | Default | Description |
|
||||
|-----------|---------|-------------|
|
||||
| `api_base` | `https://api-xecguard.cycraft.ai` | XecGuard API base URL. Falls back to `XECGUARD_API_BASE` env var. |
|
||||
| `xecguard_model` | `xecguard_v2` | XecGuard scanning model identifier. |
|
||||
| `policy_names` | `["Default_Policy_SystemPromptEnforcement", "Default_Policy_HarmfulContentProtection"]` | Policies applied on each scan. See [Available Policies](#available-policies) below. |
|
||||
| `block_on_error` | `true` | Fail-closed by default. Set to `false` for fail-open behaviour (requests pass through when the XecGuard API is unreachable). |
|
||||
| `grounding_strictness` | `BALANCED` | Either `BALANCED` or `STRICT`. Controls how strictly the `/grounding` endpoint evaluates response fidelity to supplied context documents. |
|
||||
| `default_on` | `false` | When `true`, the guardrail runs on every request without needing to specify it in the request body. |
|
||||
|
||||
## Available Policies
|
||||
|
||||
XecGuard ships with six built-in default policies. Select one or more via `policy_names`:
|
||||
|
||||
| Policy Name | Purpose |
|
||||
|-------------|---------|
|
||||
| `Default_Policy_SystemPromptEnforcement` | Ensures the user prompt stays within the tasks defined by the system prompt |
|
||||
| `Default_Policy_GeneralPromptAttackProtection` | Detects prompt injection, prompt extraction, encoded bypass attempts |
|
||||
| `Default_Policy_ContentBiasProtection` | Detects discrimination, harassment, harmful stereotypes |
|
||||
| `Default_Policy_HarmfulContentProtection` | Detects harmful speech/semantics violating public order and good morals |
|
||||
| `Default_Policy_SkillsProtection` | Detects malicious content in AI-agent skill files |
|
||||
| `Default_Policy_PIISensitiveDataProtection` | Detects personally identifiable information (PII) |
|
||||
|
||||
:::info
|
||||
The wildcard form `policy_names: ["*"]` is supported by the XecGuard API but requires your Service Token to be pre-bound to at least one policy in the XecGuard console.
|
||||
:::
|
||||
|
||||
## Context Grounding (RAG)
|
||||
|
||||
When scanning in `post_call` mode, XecGuard can additionally validate the assistant's response against reference documents via the `/grounding` endpoint. This catches hallucinations and factual drift in RAG applications.
|
||||
|
||||
Supply grounding documents at request time via the `metadata.xecguard_grounding_documents` field. Each document is `{document_id, context}`:
|
||||
|
||||
```shell
|
||||
curl -i http://0.0.0.0:4000/v1/chat/completions \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"model": "gpt-4",
|
||||
"messages": [
|
||||
{"role": "user", "content": "What nationality was Peggy Seeger?"}
|
||||
],
|
||||
"guardrails": ["xecguard-guard"],
|
||||
"metadata": {
|
||||
"xecguard_grounding_documents": [
|
||||
{
|
||||
"document_id": "peggy_seeger_bio",
|
||||
"context": "Peggy Seeger (born June 17, 1935) is an American folk singer."
|
||||
}
|
||||
]
|
||||
}
|
||||
}'
|
||||
```
|
||||
|
||||
If the assistant's response contradicts or is unsupported by the provided documents, the request is blocked with a grounding violation (`CONFLICT`, `BASELESS`, or `INCOMPLETE`):
|
||||
|
||||
```json
|
||||
{
|
||||
"error": {
|
||||
"message": "Blocked by XecGuard grounding: rules=[CONFLICT] trace_id=fabcde7890123456abcdef1234567829 rationale=Response states Peggy Seeger was British, but the document indicates she is American.",
|
||||
"type": "None",
|
||||
"param": "None",
|
||||
"code": "400"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Grounding only runs when:
|
||||
- `mode` includes `post_call`
|
||||
- `metadata.xecguard_grounding_documents` is a non-empty list
|
||||
- The messages contain both a user prompt and an assistant response
|
||||
|
||||
## Advanced Configuration
|
||||
|
||||
### Fail-Open Mode
|
||||
|
||||
By default XecGuard operates in **fail-closed** mode — if the API is unreachable, the request is blocked. Set `block_on_error: false` to allow requests through when the guardrail API fails:
|
||||
|
||||
```yaml
|
||||
guardrails:
|
||||
- guardrail_name: "xecguard-failopen"
|
||||
litellm_params:
|
||||
guardrail: xecguard
|
||||
mode: "pre_call"
|
||||
api_key: os.environ/XECGUARD_API_KEY
|
||||
block_on_error: false
|
||||
```
|
||||
|
||||
### Input + Output Pipeline
|
||||
|
||||
Apply one guardrail for input validation and another for output scanning + grounding:
|
||||
|
||||
```yaml
|
||||
guardrails:
|
||||
- guardrail_name: "xecguard-input"
|
||||
litellm_params:
|
||||
guardrail: xecguard
|
||||
mode: "pre_call"
|
||||
api_key: os.environ/XECGUARD_API_KEY
|
||||
policy_names:
|
||||
- Default_Policy_GeneralPromptAttackProtection
|
||||
- Default_Policy_SystemPromptEnforcement
|
||||
|
||||
- guardrail_name: "xecguard-output"
|
||||
litellm_params:
|
||||
guardrail: xecguard
|
||||
mode: "post_call"
|
||||
api_key: os.environ/XECGUARD_API_KEY
|
||||
policy_names:
|
||||
- Default_Policy_HarmfulContentProtection
|
||||
- Default_Policy_PIISensitiveDataProtection
|
||||
grounding_strictness: "STRICT"
|
||||
```
|
||||
|
||||
### Always-On Protection
|
||||
|
||||
Enable the guardrail for every request without specifying it per-call:
|
||||
|
||||
```yaml
|
||||
guardrails:
|
||||
- guardrail_name: "xecguard-guard"
|
||||
litellm_params:
|
||||
guardrail: xecguard
|
||||
mode: "pre_call"
|
||||
api_key: os.environ/XECGUARD_API_KEY
|
||||
default_on: true
|
||||
```
|
||||
|
||||
### Logging-Only Mode
|
||||
|
||||
Observe scan decisions without blocking — useful for shadow-mode deployment before enforcement:
|
||||
|
||||
```yaml
|
||||
guardrails:
|
||||
- guardrail_name: "xecguard-monitor"
|
||||
litellm_params:
|
||||
guardrail: xecguard
|
||||
mode: "logging_only"
|
||||
api_key: os.environ/XECGUARD_API_KEY
|
||||
```
|
||||
|
||||
Scan results are attached to the standard logging payload (`standard_logging_guardrail_information`) and surface in Langfuse / DataDog / OTEL without ever blocking a request.
|
||||
|
||||
## Full Conversation History
|
||||
|
||||
XecGuard always receives the **full conversation history** — system, user, and assistant messages — for both input and response scans. This is required for policies such as `Default_Policy_SystemPromptEnforcement` to work correctly. There is no configuration option to disable this behaviour; the framework-wide `skip_system_message_in_guardrail` setting is intentionally ignored for XecGuard.
|
||||
|
||||
## Error Handling
|
||||
|
||||
**Missing API Credentials:**
|
||||
```
|
||||
XecGuardMissingCredentials: XecGuard API key is required.
|
||||
Set XECGUARD_API_KEY in the environment or pass api_key in the guardrail config.
|
||||
```
|
||||
|
||||
**API Unreachable (fail-closed, default):**
|
||||
The request is blocked and a `GuardrailRaisedException` is raised.
|
||||
|
||||
**API Unreachable (fail-open, `block_on_error: false`):**
|
||||
The request passes through unchanged and a warning is logged.

# LiteLLM Plugin Architecture
|
||||
|
||||
Plugins let external services appear as selectable modes in the litellm UI sidebar alongside the AI Gateway.
|
||||
|
||||
---
|
||||
|
||||
## Quick start
|
||||
|
||||
### 1. Configure the plugin
|
||||
|
||||
Add a `plugins` block to your litellm `config.yaml`:
|
||||
|
||||
```yaml
|
||||
general_settings:
|
||||
master_key: sk-...
|
||||
plugins:
|
||||
- name: my-plugin # unique identifier (no spaces)
|
||||
display_name: My Plugin # shown in the UI dropdown
|
||||
url: "https://my-plugin.example.com"
|
||||
plugin_key: "sk-..." # plugin's own auth credential
|
||||
```
|
||||
|
||||
`plugin_key` is injected as `Authorization: Bearer <plugin_key>` on every
|
||||
request proxied through `/plugin-proxy/my-plugin/*`. The caller's litellm
|
||||
credential is stripped before forwarding so the plugin never receives a live
|
||||
litellm API key.
|
||||
|
||||
### 2. Implement two endpoints on your service
|
||||
|
||||
| Endpoint | Method | Purpose |
|
||||
|---|---|---|
|
||||
| `GET /api/plugin-manifest` | public | Returns plugin metadata for the UI |
|
||||
| `POST /api/plugin-auth` | public | Decrypts the identity claim for seamless sign-in |
|
||||
|
||||
#### `GET /api/plugin-manifest`
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "my-plugin",
|
||||
"display_name": "My Plugin",
|
||||
"version": "1.0.0",
|
||||
"nav_items": [
|
||||
{ "key": "home", "label": "Home", "icon": "HomeOutlined", "path": "/" },
|
||||
{ "key": "reports", "label": "Reports", "icon": "BarChartOutlined", "path": "/reports" }
|
||||
],
|
||||
"capabilities": ["reports", "data"]
|
||||
}
|
||||
```
|
||||
|
||||
#### `POST /api/plugin-auth`
|
||||
|
||||
Receives `{ "session_claim": "<fernet-ciphertext>" }`.
|
||||
|
||||
The proxy never shares `LITELLM_SALT_KEY` with your plugin. Each plugin is
|
||||
provisioned with its own dedicated key, derived as
|
||||
`HMAC-SHA256(LITELLM_SALT_KEY, plugin_name)`. Compute it once on the proxy
|
||||
host and hand the result to your plugin as a secret (e.g. `PLUGIN_AUTH_KEY`):
|
||||
|
||||
```bash
|
||||
python -c 'import base64,hmac,hashlib,os; \
|
||||
print(base64.urlsafe_b64encode(hmac.new(os.environ["LITELLM_SALT_KEY"].encode(), b"my-plugin", hashlib.sha256).digest()).decode())'
|
||||
```
|
||||
|
||||
A compromised plugin holding only this scoped key cannot recover
|
||||
`LITELLM_SALT_KEY` or decrypt any other litellm secret.
|
||||
|
||||
Decrypt and validate the claim with that key:
|
||||
|
||||
```python
|
||||
import json, os, time
|
||||
from cryptography.fernet import Fernet
|
||||
|
||||
_CLAIM_TTL_SECONDS = 30
|
||||
|
||||
def plugin_auth(session_claim: str) -> dict:
|
||||
cipher = Fernet(os.environ["PLUGIN_AUTH_KEY"].encode())
|
||||
claim = json.loads(cipher.decrypt(session_claim.encode(), ttl=_CLAIM_TTL_SECONDS))
|
||||
if claim.get("plugin") != "my-plugin":
|
||||
raise ValueError("claim audience mismatch")
|
||||
if int(claim.get("exp", 0)) < int(time.time()):
|
||||
raise ValueError("claim expired")
|
||||
return claim
|
||||
```
|
||||
|
||||
The claim is `{ "plugin", "user_id", "user_role", "exp" }`; it carries no
|
||||
litellm bearer token. Establish the plugin's own session from `user_id` /
|
||||
`user_role` and authenticate API calls back to litellm through the
|
||||
`/plugin-proxy/my-plugin/*` reverse proxy, which injects `plugin_key` for you.
|
||||
|
||||
---
|
||||
|
||||
## How iframe auth works
|
||||
|
||||
```
|
||||
litellm UI
|
||||
├─ GET /api/plugins/auth-token -> { session_claim }
|
||||
└─ postMessage({ type:"litellm-auth", session_claim }, pluginOrigin)
|
||||
│
|
||||
▼
|
||||
Plugin iframe browser
|
||||
└─ POST /api/plugin-auth { session_claim }
|
||||
│
|
||||
▼
|
||||
Plugin server
|
||||
├─ decrypt(session_claim, PLUGIN_AUTH_KEY) -> { user_id, user_role, exp }
|
||||
└─ establish plugin session -> stored in sessionStorage
|
||||
```
|
||||
|
||||
No litellm bearer token ever leaves the proxy; the claim only conveys the
|
||||
caller's identity and expires after 30 seconds. A postMessage intercept
|
||||
yields ciphertext that is useless without the plugin's scoped key.
|
||||
|
||||
---
|
||||
|
||||
## Proxy routes
|
||||
|
||||
- `GET /api/plugins` — list registered plugins (`name`, `display_name`, `url`). `plugin_key` is **never** returned; it stays server-side. Requires an authenticated caller.
|
||||
- `GET /api/plugins/auth-token?plugin_name=<name>` — short-lived encrypted identity claim for the named plugin. Requires `LITELLM_SALT_KEY` to be set (503 otherwise) and the plugin to be registered (404 otherwise).
|
||||
- `ANY /plugin-proxy/{name}/{path}` — authenticated reverse proxy to the plugin backend. Restricted to `proxy_admin`.
|
||||
|
||||
---
|
||||
|
||||
## Reverse proxy behaviour
|
||||
|
||||
When an admin (or server-to-server caller) hits `/plugin-proxy/<name>/<path>`, the proxy authenticates the caller locally, then rewrites the request before forwarding it to the plugin's `url`:
|
||||
|
||||
- **Every litellm credential header is stripped** — `Authorization`, `x-api-key`, `API-Key`, `x-goog-api-key`, `Ocp-Apim-Subscription-Key`, `x-litellm-api-key`, any configured `litellm_key_header_name`, plus `Cookie`. The plugin can never be handed the caller's live litellm key.
|
||||
- **`plugin_key` is injected** as `Authorization: Bearer <plugin_key>` — the only credential the plugin receives.
|
||||
- **Caller identity is forwarded** as `x-litellm-user-id` and `x-litellm-user-role` so the plugin can run its own authorization. These are informational, not credentials.
|
||||
- **Responses are sandboxed** — `Content-Security-Policy: sandbox` and `X-Content-Type-Options: nosniff` are set so plugin-controlled bytes served from the litellm origin cannot execute against the dashboard.
|
||||
|
||||
---
|
||||
|
||||
## Security checklist
|
||||
|
||||
- [ ] `LITELLM_SALT_KEY` is set on the proxy and never shared with the plugin
|
||||
- [ ] The plugin holds only its derived `HMAC(LITELLM_SALT_KEY, plugin_name)` key, provisioned as a dedicated secret
|
||||
- [ ] `plugin_key` is a dedicated credential scoped to the plugin (not your litellm master key)
|
||||
- [ ] Plugin's `POST /api/plugin-auth` enforces the claim's `plugin` audience and `exp` (30s TTL)
|
||||
- [ ] Plugin treats `x-litellm-user-id` / `x-litellm-user-role` as identity hints, not as proof of authentication
|
||||
- [ ] Plugin service URL uses HTTPS in production

# Adding a provider / route to litellm-rust
|
||||
|
||||
Three layers, same for every route (see `ocr` and `realtime` as references):
|
||||
|
||||
1. **Transform contract (pure)** — `crates/core/src/<route>/transformation.rs`: a `…ProviderConfig` trait (URL build + request/response transforms) + types in `types.rs`. No network, env, or auth.
|
||||
2. **Provider config (pure)** — `crates/providers/src/<provider>/<route>/transformation.rs`: implement that trait as a `const <PROVIDER>_<ROUTE>_CONFIG`, mirroring the Python provider tree. Add parity unit tests.
|
||||
3. **HTTP / transport (the host)** — `crates/providers/src/<route>.rs` (e.g. `ocr.rs`, `realtime.rs`): the callable fn (`run_ocr`, `realtime`). It resolves the key, builds the auth header, builds URL + transforms via the config, then does the network call. This is the only layer allowed to do I/O.
|
||||
|
||||
**Calling:** the host invokes the route fn — the Python bridge calls `run_ocr`; the `ai-gateway` server calls `realtime`. Register new modules in `lib.rs` / `mod.rs`, then run `cargo fmt && cargo clippy --workspace -- -D warnings && cargo test --workspace`.

litellm-rust has exactly THREE crates. A crate is a LAYER, not a route. Routes (ocr, realtime, chat) and providers (mistral, openai) are MODULES inside the layers.

## Crates
|

|
||||
| Crate | Role | Pure / I/O |
|
||||
|-------|------|------------|
|

| litellm-core | Translation layer — types, route contracts (traits), provider transforms (modules under providers/), and the router. Builds requests/responses; no network. | Pure |
|
||||
| litellm-ai-gateway | Routes + host — the only crate that touches the network. HTTP/WebSocket I/O (modules under io/) plus the axum server binary (behind the `server` feature). | I/O |
|
||||
| litellm-python-bridge | PyO3 cdylib exposing Rust to the litellm Python SDK — a thin adapter over litellm-ai-gateway's I/O. | Binding |

||||
|
||||
Dependency direction (acyclic): litellm-core ← litellm-ai-gateway ← litellm-python-bridge.
|
||||
|
||||
Adding a crate: default to a MODULE. New crate ONLY on a real trigger — separate artifact (binary/cdylib), proc-macro, shared foundation, or publishable standalone. A new provider or route is none of these.
|
||||
|
||||
Adding a crate fails crates/core/tests/workspace_crate_allowlist.rs until you update its allowlist and this file — intentional.

This file defines the rules for Rust work in LiteLLM.
|
||||
|
||||
## Crates (exactly three — see AGENTS.md)
|
||||
|
||||
`litellm-core` describes work; `litellm-ai-gateway` executes it; `litellm-python-bridge`
|
||||
exposes it to the Python SDK. A crate is a **layer**, not a route — add modules, not crates.
|
||||
|
||||
## Core Boundary
|
||||
|
||||
The `core` and `providers` crates describe work; hosts execute work.
|
||||
`litellm-core` is the pure translation layer; the `litellm-ai-gateway` host executes work.
|
||||
|
||||
Route-level Rust structure mirrors LiteLLM's Python responsibilities:
|
||||
- `core/src/<route>/` owns the route contract, shared types, and provider
|
||||
template traits. For OCR, this means `core/src/ocr`.
|
||||
- `providers/src/<provider>/<route>/transformation.rs` owns the

provider-specific transform. For Mistral OCR, this means
|

`providers/src/mistral/ocr/transformation.rs`.
|
||||
- Future network execution belongs in a host/transport layer such as
|
||||
`llm_http_handler`, not inside `core` or `providers`.
|
||||
`core/src/providers/mistral/ocr/transformation.rs`.
|
||||

|
||||
## Constants
|
||||
|
||||
Magic numbers and fixed strings go in a crate-level `constants.rs`, never
|
||||
hardcoded inline — the Rust mirror of Python's `litellm/constants.py`.
|
||||
|
||||
- Each crate that needs them has `src/constants.rs` (declared `mod constants;`);
|
||||
import from it (`use crate::constants::...`). Don't scatter `const` values at
|
||||
the top of feature modules.
|
||||
- An env-overridable tunable still lives in `constants.rs` as its `DEFAULT_*`
|
||||
value; the env read (with fallback to that default) happens at the host/config
|
||||
resolution layer, not in `core`/`providers`.

elsewhere may stay inline, but prefer `constants.rs` when in doubt.

# ai-gateway — folder architecture
|
||||
|
||||
The Axum server that fronts the Rust gateway. It owns transport + config + auth
|
||||
only; deployment selection lives in `core::router`, transforms in `core`/`providers`.
|
||||
|
||||
```
|
||||
src/
|
||||
main.rs # entrypoint: build AppState (router + master key), bind, serve
|
||||
state.rs # AppState — shared Arc<Router> + master_key
|
||||
gil.rs # GIL-activity tracker (records Python acquisitions)
|
||||
auth/ # authentication as an axum extractor — added to handler args
|
||||
mod.rs # RequireMasterKey: FromRequestParts, single master key (LITELLM_MASTER_KEY)
|
||||
routes/ # one module per route, all matching the same template
|
||||
AGENTS.md # ← the route template (read this before adding a route)
|
||||
mod.rs # app(): merges every module's router()
|
||||
health.rs # simple route (one file): router() + liveness/readiness
|
||||
gil.rs # simple route (one file): router() + GET /health/gil
|
||||
realtime/ # route with logic → axum surface + a no-axum service:
|
||||
mod.rs # router() + handler + WS<->events adapter (the axum surface)
|
||||
service.rs # business logic (select deployment, call provider) — no axum, testable
|
||||
python/ # Python interop (feature: python-config) — load-time only
|
||||
mod.rs, config.rs, AGENTS.md
|
||||
```
|
||||
|
||||
## Rules
|
||||
|
||||
- **Routes follow one template.** Each route module exposes
|
||||
`pub fn router() -> Router<AppState>`; `routes/mod.rs` only merges them. Simple
|
||||
routes are one file; non-trivial routes are a folder (`handler`/`service`/
|
||||
`transport`). See `routes/AGENTS.md`.
|
||||
- **Auth is an extractor.** Add `crate::auth::RequireMasterKey` to a handler's
|
||||
args; it runs during extraction. Never re-implement the check per route.
|
||||
- **Handlers are thin.** A handler validates and delegates to its `service`. No
|
||||
business logic, no provider calls, no transforms in handlers.
|
||||
- **State is shared and cheap to clone.** Long-lived handles live behind `Arc` in
|
||||
`state.rs`; read env/config only in `main.rs` when building state.
|
||||
|
||||
## Auth (interim)
|
||||
|
||||
A single **master key** (`LITELLM_MASTER_KEY`), enforced by the
|
||||
`auth::RequireMasterKey` extractor: any caller presenting it as
|
||||
`Authorization: Bearer <key>` may invoke the gateway. Fails closed (500) when
|
||||
unset; constant-time compare. The server binds `127.0.0.1` by default (`HOST` to
|
||||
override). Full per-key auth + budgets/rate-limits are delegated to the Python
|
||||
proxy in a later phase. Health routes don't add the extractor (unauthenticated).
|
||||
|
||||
## Python interop
|
||||
|
||||
Anything that calls into Python lives in `python/` and is **load-time only** — see
|
||||
`python/AGENTS.md`. The realtime data path never takes the GIL.

# ai-gateway architecture
|
||||
|
||||
The Rust ai-gateway does LLM inference (realtime WebSocket). Spend tracking is an
|
||||
API callback: it POSTs each finished session to the LiteLLM proxy, which records
|
||||
spend and runs the usual callbacks.

# LiteLLM Rust AI Gateway
|
||||
|
||||
A minimal Axum service that fronts OpenAI's realtime API. Clients open a
|
||||
WebSocket to `GET /v1/realtime`; the gateway authenticates, selects a deployment,
|
||||
dials OpenAI upstream, and splices the two sockets frame-by-frame.
|
||||
|
||||
## Crates
|
||||
|
||||
`litellm-rust` is exactly three crates (a crate is a **layer**, not a route):
|
||||
|
||||
| Crate | Role | Pure / I/O |
|
||||
|-------|------|------------|
|
||||
| litellm-core | Translation layer — types, route contracts (traits), provider transforms (modules under `providers/`), and the router. Builds requests/responses; no network. | Pure |
|
||||
| litellm-ai-gateway | Routes + host — the only crate that touches the network. HTTP/WebSocket I/O (modules under `io/`) plus the Axum server binary (behind the `server` feature). | I/O |
|
||||
| litellm-python-bridge | PyO3 cdylib exposing Rust to the litellm Python SDK — a thin adapter over litellm-ai-gateway's I/O. | Binding |
|
||||
|
||||
Dependency direction (acyclic): litellm-core ← litellm-ai-gateway ← litellm-python-bridge.
|
||||
|
||||
- **Client endpoint:** `wss://<host>/v1/realtime?model=<model>` (WebSocket)
|
||||
- **Auth:** `Authorization: Bearer $LITELLM_MASTER_KEY` (fails closed if unset)
|
||||
- **Health:** `GET /health/readiness`, `GET /health/liveness`, `GET /health/gil`
|
||||
- **Request logs:** POSTed to a LiteLLM proxy at `/v1/rust_control_plane/logs` (see [Request logging](#request-logging))
|
||||

> **Realtime serving is pure Rust.** Python is used at **load time only** — to
|
||||
> read the config once at boot. The realtime hot path never touches Python.
|
||||
|
||||
## Configuration (config.yaml)
|
||||
|
||||
The gateway loads its `model_list` from a **config.yaml**, the same as the
|
||||
LiteLLM proxy. Point `LITELLM_CONFIG_PATH` at the file:
|
||||
|
||||
```yaml
|
||||
# config.yaml
|
||||
model_list:
|
||||
- model_name: gpt-realtime
|
||||
litellm_params:
|
||||
model: openai/gpt-realtime
|
||||
api_key: os.environ/OPENAI_API_KEY
|
||||
```
|
||||
|
||||
```bash
|
||||
LITELLM_CONFIG_PATH=./config.yaml ./litellm-ai-gateway
|
||||
```
|
||||
|
||||
At boot the gateway calls into `litellm.proxy.read_model_list`, which reuses the
|
||||
**real proxy config reader** (`ProxyConfig.get_config`). That means everything
|
||||
the proxy supports in config.yaml works here too:
|
||||
|
||||
- `include:` to merge in other config files,
|
||||
- `os.environ/VAR` secret references (resolved via the secret manager, never
|
||||
inlined),
|
||||
- DB-stored models (when a database is configured).
|
||||
|
||||
Secrets stay out of the config — reference them with `os.environ/...` and set
|
||||
the env var at deploy time. The shipped Docker image is built with the
|
||||
`python-config` feature and **bundles litellm**, so config loading works out of
|
||||
the box; the default baked config lives at `/app/config.yaml` and can be
|
||||
overridden at deploy time (e.g. a Render secret file mounted at the same path).
|
||||
|
||||
### Environment variables
|
||||
|
||||
| Var | Required | Default | Purpose |
|
||||
|---|---|---|---|
|
||||
| `LITELLM_CONFIG_PATH` | yes (config mode) | — | Path to the config.yaml the gateway loads its `model_list` from. The Docker image defaults this to `/app/config.yaml`. |
|
||||
| `LITELLM_MASTER_KEY` | yes | — | Bearer token clients must send. Unset ⇒ all `/v1/realtime` requests are rejected (fail closed). |
|
||||
| `OPENAI_API_KEY` | yes | — | Upstream OpenAI key. Referenced by config.yaml as `os.environ/OPENAI_API_KEY` for the gateway→OpenAI dial. |
|
||||
| `HOST` | no | `127.0.0.1` | **Set to `0.0.0.0` in any container/deploy** or external traffic is refused. |
|
||||
| `PORT` | no | `4001` | Listen port. Render and most PaaS inject this automatically. |
|
||||
| `LITELLM_PROXY_BASE_URL` | no | `http://localhost:4000` | LiteLLM proxy that request logs are POSTed to. See [Request logging](#request-logging). |
|
||||
|
||||
> Secrets (`LITELLM_MASTER_KEY`, `OPENAI_API_KEY`) are never baked into the image
|
||||
> or `render.yaml` — inject them at deploy time only.
|
||||
|
||||
### Lean env stand-in (fallback)
|
||||
|
||||
If the binary is built **without** `python-config` (default features), or
|
||||
`LITELLM_CONFIG_PATH` is unset, the gateway falls back to a single-deployment
|
||||
stand-in built from the environment:
|
||||
|
||||
| Var | Default | Purpose |
|
||||
|---|---|---|
|
||||
| `OPENAI_REALTIME_MODEL` | `gpt-realtime` | The single deployment's model name (also the `?model=` clients pass). |
|
||||
|
||||
This mode links no libpython and needs no config file, but it only supports one
|
||||
hard-coded OpenAI deployment. **config.yaml is the recommended path** — use the
|
||||
stand-in only for the leanest possible build.
|
||||
|
||||
## Request logging
|
||||
|
||||
The gateway runs no spend logic. When a session ends it builds one
|
||||
`StandardLoggingPayload` and POSTs it to `{LITELLM_PROXY_BASE_URL}/v1/rust_control_plane/logs`
|
||||
(admin-only, bearer = `LITELLM_MASTER_KEY`), and the proxy replays it through its
|
||||
normal callbacks (spend logs, Langfuse, etc.). The POST is non-blocking: a bounded
|
||||
channel drained by a background worker, dropping with a counter if the proxy is
|
||||
down. It sends one payload per session. Both env vars are in the table above.
|
||||
|
||||
Worker tuning, rarely needed: `LITELLM_LOG_CHANNEL_CAPACITY` (4096),
|
||||
`LITELLM_LOG_BATCH_SIZE` (256), `LITELLM_LOG_FLUSH_INTERVAL_MS` (500).
|
||||
|
||||
## Build & run with Docker
|
||||
|
||||
The image is built `--features python-config` and installs litellm **from this
|
||||
repo's source** (the config reader is newer than any PyPI release), so the build
|
||||
**context is the repo root**:
|
||||
|
||||
```bash
|
||||
# from the repo root
|
||||
docker build -f litellm-rust/crates/ai-gateway/Dockerfile -t litellm-ai-gateway .
|
||||
|
||||
docker run --rm -p 4001:4001 \
|
||||
-e HOST=0.0.0.0 -e PORT=4001 \
|
||||
-e LITELLM_MASTER_KEY=sk-local \
|
||||
-e OPENAI_API_KEY=$OPENAI_API_KEY \
|
||||
litellm-ai-gateway # LITELLM_CONFIG_PATH defaults to /app/config.yaml
|
||||
|
||||
# smoke test
|
||||
curl -s -o /dev/null -w '%{http_code}\n' localhost:4001/health/readiness # -> 200
|
||||
curl -s -o /dev/null -w '%{http_code}\n' localhost:4001/v1/realtime # -> 401 (auth fails closed)
|
||||
```
|
||||
|
||||
On boot you should see `loaded model_list from /app/config.yaml via python
|
||||
config reader` — that confirms the config path (not the env stand-in fallback).
|
||||
To use your own config, mount it over the default:
|
||||
|
||||
```bash
|
||||
docker run --rm -p 4001:4001 \
|
||||
-e HOST=0.0.0.0 -e LITELLM_MASTER_KEY=sk-local -e OPENAI_API_KEY=$OPENAI_API_KEY \
|
||||
-v $(pwd)/my-config.yaml:/app/config.yaml:ro \
|
||||
litellm-ai-gateway
|
||||
```
|
||||
|
||||
### Cargo-only (no Docker)
|
||||
|
||||
```bash
|
||||
# config.yaml mode — needs litellm importable in the active python env
|
||||
LITELLM_CONFIG_PATH=./crates/ai-gateway/config.yaml \
|
||||
cargo run --release -p litellm-ai-gateway --features python-config
|
||||
|
||||
# env stand-in mode — no python, no config
|
||||
cargo run --release -p litellm-ai-gateway
|
||||
```
|
||||
|
||||
## Deploy on Render
|
||||
|
||||
The service is a Docker **web service**; Render terminates TLS and supports
|
||||
WebSockets, so the public endpoint is `wss://<service>.onrender.com/v1/realtime`.
|
||||
|
||||
### Option A — Blueprint (`render.yaml`)
|
||||
|
||||
`crates/ai-gateway/render.yaml` describes the service (Docker runtime,
|
||||
`healthCheckPath: /health/readiness`, repo-root `dockerContext: .`,
|
||||
`dockerfilePath: ./litellm-rust/crates/ai-gateway/Dockerfile`,
|
||||
`LITELLM_CONFIG_PATH: /app/config.yaml`). `LITELLM_MASTER_KEY` and
|
||||
`OPENAI_API_KEY` are `sync: false` — set them in the dashboard after the first
|
||||
deploy. To use a non-default model_list, mount a **Render Secret File** at
|
||||
`/app/config.yaml`. Point a Render Blueprint at this repo/branch and apply.
|
||||
|
||||
### Option B — Render API
|
||||
|
||||
```bash
|
||||
# create a Docker web service from this repo+branch, then set env vars:
|
||||
curl -X POST https://api.render.com/v1/services \
|
||||
-H "Authorization: Bearer $RENDER_API_KEY" -H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"type": "web_service", "name": "litellm-rust-ai-gateway",
|
||||
"ownerId": "<owner-id>", "repo": "https://github.com/BerriAI/litellm",
|
||||
"branch": "<branch-with-this-dockerfile>",
|
||||
"serviceDetails": {
|
||||
"env": "docker",
|
||||
"envSpecificDetails": {
|
||||
"dockerfilePath": "./litellm-rust/crates/ai-gateway/Dockerfile",
|
||||
"dockerContext": "."
|
||||
},
|
||||
"healthCheckPath": "/health/readiness"
|
||||
}
|
||||
}'
|
||||
# then set env vars LITELLM_MASTER_KEY, OPENAI_API_KEY, HOST=0.0.0.0,
|
||||
# LITELLM_CONFIG_PATH=/app/config.yaml
|
||||
```
|
||||
|
||||
Health check path **must** be `/health/readiness`. `autoDeploy` is off by default
|
||||
in the blueprint — trigger deploys manually (or flip it on) to pick up new commits.
|
||||
|
||||
## Scaling
|
||||
|
||||
Concurrency is what matters, not total connections: each in-flight session holds
|
||||
one client socket + one upstream socket. To scale, raise the instance count /
|
||||
enable autoscaling on the Render service (e.g. baseline 10, max 100). Each
|
||||
instance needs file descriptors for `2 × peak_concurrent_sessions` — raise
|
||||
`ulimit -n` if you push very high concurrency.
|
||||
|
||||
## Latency note
|
||||
|
||||
The gateway adds the cost of one extra hop: client→gateway, then a fresh
|
||||
gateway→OpenAI realtime handshake (TLS + WS upgrade + `session.created`). In
|
||||
benchmarks this is ~100–150 ms of added session-establishment time; first-audio
|
||||
and steady-state streaming add no measurable overhead. To minimize it, deploy the
|
||||
gateway in the Render region with the lowest RTT to OpenAI's realtime endpoint.

# Realtime gateway benchmark — pool on/off
|
||||
|
||||
Measures what the gateway adds over talking to OpenAI's realtime WebSocket
|
||||
directly, and what the pre-warmed connection pool removes. See
|
||||
`../../src/routes/realtime/README.md` for how the pool works.
|
||||
|
||||
## Results
|
||||
|
||||
5000 calls / 500 concurrency, gateway at 10 instances, pool ON
|
||||
(`REALTIME_POOL_SIZE=64`), upstream OpenAI `gpt-realtime`. Each leg run twice.
|
||||
Times in **ms**. Phases per connection: **dial** = TCP+TLS+WS upgrade,
|
||||
**session** = upgrade → `session.created` (the phase the pool removes),
|
||||
**1st-audio** = `response.create` → first audio delta (OpenAI inference),
|
||||
**total** = full wall-clock.
|
||||
|
||||
| metric | Direct OpenAI | Gateway (pool ON) | Overhead (ms) | vs OpenAI |
|
||||
| ------------------ | ------------- | ----------------- | ------------- | ---------- |
|
||||
| success rate (%) | 99.8 | 99.8 | — | — |
|
||||
| dial p50 (ms) | 276 | 158 | −118 | **faster** |
|
||||
| session p50 (ms) | 7 | 0 | −7 | **faster** |
|
||||
| 1st-audio p50 (ms) | 440 | 664 | +224 | slower¹ |
|
||||
| total p50 (ms) | 816 | 1010 | +194 | slower¹ |
|
||||
| total p95 (ms) | 2152 | 1970 | −182 | **faster** |
|
||||
| total p99 (ms) | 2692 | 2610 | −82 | **faster** |
|
||||
|
||||
The gateway is **faster than direct on 4 of 6 metrics**. The warm pool makes the
|
||||
**session phase sub-millisecond** at the median — ~76% of connects hit the pool,
|
||||
~70% had session < 1 ms. ¹ The two "slower" rows are not gateway overhead:
|
||||
`1st-audio` is OpenAI's own inference time (the gateway only relays it), which ran
|
||||
slower during the gateway legs and drags `total p50` with it.
|
||||
|
||||
**Pool OFF** (control, `REALTIME_POOL_SIZE=0`): session p50 was **367 ms** — the
|
||||
fresh-dial overhead the pool removes.
|
||||
|
||||
## Reproduce
|
||||
|
||||
The load generator lives in a separate repo:
|
||||
**https://github.com/ishaan-berri/litellm-realtime-bench**
|
||||
|
||||
```bash
|
||||
git clone https://github.com/ishaan-berri/litellm-realtime-bench
|
||||
cd litellm-realtime-bench && go build -o wsbench .
|
||||
|
||||
# Direct to OpenAI (baseline)
|
||||
./wsbench -host api.openai.com -key "$OPENAI_API_KEY" -m gpt-realtime -n 5000 -c 500 -t 60
|
||||
|
||||
# Through the gateway — run once with pool ON, once with REALTIME_POOL_SIZE=0
|
||||
./wsbench -host <gateway-host> -key "$LITELLM_MASTER_KEY" -m gpt-realtime -n 5000 -c 500 -t 60
|
||||
```
|
||||
|
||||
Run the gateway with the env stand-in (`OPENAI_REALTIME_MODEL=gpt-realtime`,
|
||||
`OPENAI_API_KEY`, `LITELLM_MASTER_KEY`, `REALTIME_POOL_SIZE`, `HOST=0.0.0.0`). At
|
||||
500 concurrency over N instances, size the pool to `≈ 500 / N` per instance (64 was
|
||||
used here for 10 instances). The bench repo's README covers running 500-concurrency
|
||||
legs from a hosted multi-vCPU runner. **Never commit keys — pass them via `-key`.**

# LiteLLM Rust integrations
|
||||
|
||||
This directory contains Rust-native equivalents of LiteLLM integration hooks.
|
||||
The first supported surfaces are terminal custom loggers and pre/during-call
|
||||
custom guardrails.
|
||||
|
||||
## File layout
|
||||
|
||||
Every integration is a folder:
|
||||
|
||||
- `mod.rs` contains the implementation, trait, runner, or adapter
|
||||
- `types.rs` contains the integration-local request, response, error, and future
|
||||
types
|
||||
|
||||
Do not add new flat integration files such as `custom_logger.rs`. Shared wire
|
||||
contracts that are used by multiple integrations can stay in
|
||||
`integrations/types.rs`.
|
||||
|
||||
Call ordering and lifecycle timing live in `litellm-core/src/call_lifecycle`.
|
||||
Call-type modules, such as OCR, adapt their request and response shapes into
|
||||
that generic lifecycle runner.
|
||||
|
||||
## CustomLogger
|
||||
|
||||
Implement `CustomLogger` when Rust code needs to observe terminal success or
|
||||
failure events. Method names intentionally match Python `CustomLogger` names.
|
||||
|
||||
```rust
|
||||
use litellm_ai_gateway::integrations::custom_logger::{
|
||||
CallbackTiming, CallbackValue, CustomLogger, LogFuture, ModelCallDetails,
|
||||
};
|
||||
|
||||
struct RecordingLogger;
|
||||
|
||||
impl CustomLogger for RecordingLogger {
|
||||
fn async_log_success_event<'a>(
|
||||
&'a self,
|
||||
model_call_details: &'a ModelCallDetails,
|
||||
response_obj: &'a CallbackValue,
|
||||
timing: CallbackTiming,
|
||||
) -> LogFuture<'a> {
|
||||
Box::pin(async move {
|
||||
let model = &model_call_details.model;
|
||||
let provider = &model_call_details.custom_llm_provider;
|
||||
let call_type = model_call_details.call_type.to_string();
|
||||
let request_id = model_call_details.request_id.as_deref();
|
||||
let response_object = &response_obj.object;
|
||||
let duration = timing.end_time - timing.start_time;
|
||||
let standard_payload = model_call_details.standard_logging_payload.as_ref();
|
||||
|
||||
Ok(())
|
||||
})
|
||||
}
|
||||
|
||||
fn async_log_failure_event<'a>(
|
||||
&'a self,
|
||||
model_call_details: &'a ModelCallDetails,
|
||||
response_obj: Option<&'a CallbackValue>,
|
||||
timing: CallbackTiming,
|
||||
) -> LogFuture<'a> {
|
||||
Box::pin(async move {
|
||||
let error = model_call_details.failure_error.as_ref();
|
||||
let response_object = response_obj.map(|value| value.object.as_str());
|
||||
let duration = timing.end_time - timing.start_time;
|
||||
|
||||
Ok(())
|
||||
})
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Use `CustomLoggerRunner` to fan out terminal events to configured loggers. The
|
||||
runner is a no-op when no loggers are configured, which is the expected fast
|
||||
path for requests without callbacks.
|
||||
|
||||
## CustomGuardrail
|
||||
|
||||
Implement `CustomGuardrail` when Rust code needs to run pre-call or native
|
||||
during-call checks. Method names intentionally match Python `CustomGuardrail`
|
||||
entrypoints inherited from Python `CustomLogger`.
|
||||
|
||||
```rust
|
||||
use litellm_ai_gateway::integrations::custom_guardrail::{
|
||||
CustomGuardrail, GuardrailContext, GuardrailDecision, GuardrailEventHook,
|
||||
GuardrailFuture, GuardrailRequest,
|
||||
};
|
||||
|
||||
struct BlocklistedPromptGuardrail;
|
||||
|
||||
impl CustomGuardrail for BlocklistedPromptGuardrail {
|
||||
fn guardrail_name(&self) -> &str {
|
||||
"blocklisted-prompt"
|
||||
}
|
||||
|
||||
fn supported_event_hooks(&self) -> &[GuardrailEventHook] {
|
||||
&[GuardrailEventHook::PreCall]
|
||||
}
|
||||
|
||||
fn async_pre_call_hook<'a>(
|
||||
&'a self,
|
||||
_context: &'a GuardrailContext,
|
||||
request: GuardrailRequest,
|
||||
) -> GuardrailFuture<'a> {
|
||||
Box::pin(async move {
|
||||
if request.data.to_string().contains("blocked phrase") {
|
||||
return Ok(GuardrailDecision::Block(
|
||||
litellm_ai_gateway::integrations::custom_guardrail::GuardrailError::blocked(
|
||||
"blocked phrase detected",
|
||||
),
|
||||
));
|
||||
}
|
||||
Ok(GuardrailDecision::Allow(request))
|
||||
})
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Use `CustomGuardrailRunner::run_pre_call` for `pre_call` guardrails and
|
||||
`CustomGuardrailRunner::run_during_call` for `during_call` guardrails. A
|
||||
`GuardrailDecision::Mask` continues with modified request data.
|
||||
`GuardrailDecision::Block` short-circuits the provider call.
|
||||
|
||||
## Current boundary
|
||||
|
||||
These are Rust-only primitives. Python callback and guardrail adapters are a
|
||||
separate layer that should implement these Rust traits instead of changing the
|
||||
runner interfaces.

//! Pre-warmed upstream realtime connection pool.
|
||||
//!
|
||||
//! The gateway's realtime overhead lives entirely in session establishment: on
|
||||
//! every client connect it dials a fresh upstream WS to OpenAI and waits for
|
||||
//! `session.created` before it can serve. This pool keeps a small set of upstream
|
||||
//! sockets **already connected and already past `session.created`** so a connect
|
||||
//! can be served from a warm socket and the handshake is off the critical path.
|
||||
//!
|
||||
//! Layering: this lives in the gateway's `io` module next to the dial/splice it
|
||||
//! reuses. The gateway holds an `Arc<RealtimePool>` in its state and asks for a
|
||||
//! warm socket per connect; on a miss it fresh-dials exactly as before. The pool
|
||||
//! is a latency optimization, never a correctness dependency — see the gateway's
|
||||
//! `src/routes/realtime/README.md`.
|
||||
//!
|
||||
//! ## Caveats (enforced here)
|
||||
//! - One warm socket serves exactly one session (realtime isn't multiplexed), so
|
||||
//! the pool is sized to the connect *rate*, not concurrent connections.
|
||||
//! - `session.created` is pre-read once and buffered; nothing else is read from a
|
||||
//! warm socket before handoff, so a warm session starts at OpenAI defaults just
|
||||
//! like a fresh one (`session.update` semantics unchanged).
|
||||
//! - Warm sockets are short-lived (`max_idle`) and liveness-checked at handoff to
|
||||
//! bound idle billing / dodge OpenAI's idle timeout.
|
||||
//! - On miss or dead socket the caller fresh-dials; the pool never blocks or fails
|
||||
//! a connect because it is empty.

//! LiteLLM AI Gateway — a minimal Axum server fronting the Rust router.
|
||||
//!
|
||||
//! Flow: client → `POST /v1/realtime` → `router.realtime()` selects a deployment
|
||||
//! (simple-shuffle) → `io::realtime::realtime()` invokes OpenAI. The
|
||||
//! server owns transport + config; routing lives in the `router` crate.
|
||||
//!
|
||||
//! The binary requires the `server` feature (declared in `Cargo.toml` via
|
||||
//! `required-features`), so cargo skips it unless that feature is on. Everything
|
||||
//! the binary needs lives in the library (`litellm_ai_gateway`); `main` just
|
||||
//! wires startup.

# ai-gateway/src/python — Python interop (load-time only)
|
||||
|
||||
Functions here embed the Python interpreter (pyo3) and take the GIL to call into
|
||||
`litellm` (e.g. read the proxy `model_list`). Compiled only under the
|
||||
`python-config` feature.
|
||||
|
||||
## Hard rule: non-hot-path functions only
|
||||
|
||||
Everything in this folder MUST run **at most once per process lifetime — at
|
||||
startup / load time** (config read, warm-up). NEVER call into Python on the
|
||||
request path:
|
||||
|
||||
- No GIL acquisition per request, per connection, or per realtime event.
|
||||
- No Python call inside a route handler, the router's hot path, or any loop that
|
||||
scales with traffic.
|
||||
|
||||
**Why:** the GIL serializes execution and would cap throughput; the realtime data
|
||||
path must stay pure Rust. Every acquisition is recorded by `crate::gil` — poll
|
||||
`GET /health/gil`, and `total_acquisitions` MUST stay flat under load.
|
||||
|
||||
## How to add one
|
||||
|
||||
Resolve whatever Python-derived data you need **once at boot** and hand the rest
|
||||
of the gateway an owned, plain-Rust value (e.g. build a `Router` from the
|
||||
resolved `model_list`). Record the acquisition via `crate::gil::record_acquisition()`
|
||||
immediately before taking the GIL. If a function would need to run per request,
|
||||
it does not belong here — move the work to Rust, or pre-resolve it at startup.

# routes/ — the route template
|
||||
|
||||
Every route follows the **same shape** so the layout is predictable. The rule:
|
||||
|
||||
> **Each route module exposes `pub fn router() -> Router<AppState>`.**
|
||||
> `routes/mod.rs::app` merges them all and applies state once. Adding a route is:
|
||||
> create the module, then add one `.merge(<name>::router())` line.
|
||||
|
||||
## Default: one file
|
||||
A route is a single file containing `router()` + its handler(s) (handlers stay
|
||||
private). This is the norm — don't split until it hurts.
|
||||
```
|
||||
pub fn router() -> Router<AppState> { Router::new().route(PATH, get(handle)) }
|
||||
async fn handle(...) -> impl IntoResponse { ... }
|
||||
```
|
||||
`health.rs` and `gil.rs` are examples.
|
||||
|
||||
## Split out `service` when there's real logic
|
||||
When a route has business logic worth testing without axum, put it in a sibling
|
||||
`service` (a file, or a folder if the route grows). The route file stays the
|
||||
**axum surface** (router + handler + any socket/SSE adapter); `service` is plain

Rust with **no axum types**. `realtime/` is the example:
|
||||
```
|
||||
realtime/
|
||||
mod.rs # axum surface: router() + handler + the WS<->events adapter
|
||||
service.rs # pure logic: select deployment + call provider (no axum) — testable
|
||||
```
|
||||
Split `service` further (or add `transport`, `repo`, …) only once a single file
|
||||
genuinely gets hard to read.
|
||||
|
||||
## Invariants
|
||||
- **Auth is an extractor, not a manual call.** A handler requires auth by adding
|
||||
`crate::auth::RequireMasterKey` to its arguments; it runs during extraction.
|
||||
Never re-implement the check per route.
|
||||
- **Handlers contain no business logic; `service` contains no axum types.**
|
||||
- A route owns its paths in its own `router()`; `mod.rs` only merges.
|
||||
- Cross-cutting concerns (logging, CORS, timeouts) → Tower layers in `mod.rs`,
|
||||
not duplicated in handlers.
