A source must change its stamp whenever a key or a key's group changes, since those are the two things the index holds + +| Source | Stamp | Blind spot | +|---|---|---| +| `Catalog`'s `CatalogRows` | `()`, every change goes through `Store::edit`, which drops the index | none | +| python-bridge's bound `litellm.model_cost` | the dict object and its `len` | a delete plus an add between two reads, or a `litellm_provider` rewrite on an existing key | + +A source with a blind spot calls `Store::invalidate` when it knows keys changed. Until then a key added in the blind spot is not found, and a key moved to another provider stays listed under the old one. Removed keys are still never returned + +## Tests + +Tests live in `mod.rs`'s `tests` module and drive the store through `ModelCost`, a fake `litellm.model_cost` with real bundled keys whose row is just its `litellm_provider`. Each Python write is a method (`set`, `del`, `rebind`) and its stamp is what python-bridge can see. Add a scenario as a named test that reads like the Python user code it stands for + +The two property tests compare every answer with a linear scan of the same dict. With a stamp that sees every key change, answers must match exactly. With the dict stamp, every answer must be sound (present, same folded name), and `invalidate` must make them match again. A store change that fails either is a bug in the store, not in the test diff --git a/litellm-rust/crates/model-catalog/src/store/mod.rs b/litellm-rust/crates/model-catalog/src/store/mod.rs new file mode 100644 index 00000000000..2220526f8b6 --- /dev/null +++ b/litellm-rust/crates/model-catalog/src/store/mod.rs @@ -0,0 +1,460 @@ +mod name_index; + +use std::borrow::Cow; +use std::fmt; +use std::sync::{PoisonError, RwLock}; + +use name_index::NameIndex; + +/// Where a `Store`'s rows live.

Each is a thin wrapper over +//! `call(op, request)`. +//! - Eight entry points: `registry()`, `settings()`, `health()`, `select()`, `apply()`, +//! `observe()`, `register_plugin()` and `retire()`. +//! +//! Every other member that outside code uses today has a named replacement among those. The old +//! names stay available for about a month through a `DeprecatedRouterMembers` mixin, which +//! implements them over the entry points and warns on use. A CI check +//!

"Registry" is the router's view of what is configured; per-model pricing +//! and capabilities are the model catalog (`litellm-model-catalog`), which the router reads +//! through its dynamic config. +//! - `RouterConfig` / `RouterDynamicConfig`: everything the router needs to know, passed in. The +//! router never reads process globals. Static config (model list, strategy, retry, timeout and +//! cooldown policy, Redis settings, plugins) is fixed for the router's life. Dynamic config +//! (pricing, model aliases, fallbacks, retry counts, callbacks) is a versioned snapshot read +//! once per call. +//! - `Settings`: one typed, frozen view of the configuration a caller may read. +//! - `Health`: cooldowns, blocked deployments and usage, kept in shared cache keys so Python and +//! Rust workers see the same state. `report(id, outcome)` records outcomes the router did not +//! see itself (a health check, an interceptor that marks a deployment failed). +//! - `select(model, request)`: resolve a name, filter eligible deployments, pick one with the +//! configured strategy, without calling it. +//! - `apply(changes)`: one `ChangeSet` (upserts, deletes, settings), applied atomically, producing +//! a new registry version. +//! - `call(op, request)`: select, run the attempt, and retry or fall back until it succeeds or the +//! policy is exhausted. +//! +//! # Execution +//!

If the keychain is locked at that moment it says so, and re-running it once the keychain is unlocked finishes the job. -The stored credential is a short-lived, per-session agent token, not a managed virtual key. It is scoped to the user and team you logged in as and inherits their models and budgets; spend is tracked against the shared team and user budgets rather than a separate per-session cap, so multiple logins or several concurrent agents all draw down the same allowance. It is short-lived by design (default 24h, configurable via `LITELLM_CLI_JWT_EXPIRATION_HOURS`); re-run `lite login` to refresh it and pick up your latest team and user settings. `lite auth print-token` (usable as Claude Code's `apiKeyHelper`) prints it while fresh and fails once it expires -- there is no silent renewal. It is accepted on a default deployment without `EXPERIMENTAL_UI_LOGIN`, does not appear in the Keys UI, and cannot be rotated or revoked mid-session.

The entry references the key as `$LITELLM_PROXY_API_KEY`, which the wrapper exports for the session, so the token itself never lands on disk and plain `pi` outside the wrapper simply shows the litellm models as unavailable.

Give them the command as `LITELLM_MODE=PRODUCTION /litellm --setup`, with `` replaced by the folder `uv tool dir --bin` prints, to run from the folder they want the config in. It writes `litellm_config.yaml` there with the provider keys and master key in plain text and offers to start the proxy, which then listens on every network interface and stops with Ctrl+C in that window. When the user is done, run this in that folder. It makes the file readable only by them, keeps it out of git (the wizard does neither), and prints only the model names.

Check prerequisites + +```bash +uv --version; docker info --format '{{.ServerVersion}}'; docker compose version; curl --version | head -1; openssl version; command -v python3 +``` + +On native Windows, ask the user to run Claude Code inside WSL, since every command here is POSIX shell. Every path needs curl, openssl, and python3, so ask the user to install any that is missing. The uv path needs uv, which downloads a supported Python (LiteLLM supports 3.10 to 3.14) when the `--python` range in step 4 rules out the one on the machine. If uv is missing, offer to install it, and only after the user says yes run `curl -LsSf https://astral.sh/uv/install.sh | env UV_NO_MODIFY_PATH=1 sh`, which leaves their shell profile alone (https://docs.astral.sh/uv/getting-started/installation/). It puts uv in `~/.local/bin`, so start every later command that runs `uv` or `litellm` with `export PATH="$HOME/.local/bin:$PATH";`. The Docker path needs a running Docker daemon, and the quickstart also needs Docker Compose v2. If `docker info` says `permission denied`, the user's account cannot use Docker without sudo.

Postgres with Docker: run the quickstart + +The repo's quickstart starts the gateway, Postgres, and the Admin UI in Docker, listening on this machine only, and puts a `litellm-gateway` command in that folder that stops, starts, updates, or removes them. It asks nothing when it has no terminal. It writes the master key, salt key, and database password to its own `.env` and never prints them. Download it, then run it with the folder and port from step 1. It returns once the gateway is ready: + +```bash +curl -fsSL https://raw.githubusercontent.com/BerriAI/litellm/main/scripts/quickstart.sh -o quickstart.sh +LITELLM_DIR="$PWD/litellm-gateway" LITELLM_PORT=4000 sh quickstart.sh --yes +cd litellm-gateway +``` + +Models live in the database here, so add each one through the API instead of a `config.yaml`, naming it the way step 5 says. Pipe the request body in, so the provider key never shows up in output or on a command line. Unless the user agreed to the key in your environment, as step 5 says, ask them to add the line `OPENAI_API_KEY=` to this `.env` themselves.

Install + +uv: + +```bash +uv tool install --python '>=3.10,<3.15' 'litellm[proxy]' +export PATH="$(uv tool dir --bin):$PATH"; litellm --version +``` + +With their own Postgres, install `'litellm[proxy,extra_proxy]'` instead, with the same `--python` range, which adds the Prisma client the proxy uses for the database. Running `uv tool install` again with the new extras replaces the old install. Start every later command that runs `litellm` with `export PATH="$(uv tool dir --bin):$PATH";`, so this install runs even when the shell has no `litellm` or an older one from a venv or `pip install litellm`. `uv tool update-shell` puts it on the PATH of new shells by editing the user's shell profile, so run it only after the user says yes + +Docker: + +```bash +docker pull docker.litellm.ai/berriai/litellm:main-stable +``` + +## 5. Write `.env` and `config.yaml` + +Run every command from here on in the folder from step 1. Create `.env` readable only by the user, keep it out of git, and add a master key unless it already has one. The proxy refuses to start without one, and `sk-` is the format of every key it issues: + +```bash +mkdir -p litellm-proxy && cd litellm-proxy +touch .env && chmod 600 .env; grep -qx '.env' .gitignore 2>/dev/null || echo '.env' >> .gitignore +grep -q '^LITELLM_MASTER_KEY=.' .env || printf 'LITELLM_MASTER_KEY=sk-%s\n' "$(openssl rand -hex 32)" >> .env +``` + +Copy a provider key that is already in your environment only after the user agreed to that variable, in their step 1 answer or when you ask now, and copy it without printing it, as in `printf 'OPENAI_API_KEY=%s\n' "$OPENAI_API_KEY" >> .env`. Otherwise ask the user to add the line `OPENAI_API_KEY=` to `.env` themselves and tell you when it is there. If they paste a key into the chat anyway, write it to `.env` and never repeat it. Keep one `NAME=value` per line with no quotes, so `docker --env-file` and the loader line read the same value + +Confirm each model's current LiteLLM name in the cost map instead of trusting memory, since model names go stale fast. This prints the chat models of the provider named last (`openai`, `anthropic`, `gemini`, `azure`, `bedrock`, `vertex_ai`, and so on) the way `config.yaml` takes them, with the provider in front. It matches by prefix, so `bedrock` also lists the newer Bedrock models and `vertex_ai` lists every Vertex family. For Ollama, use a model from `ollama list` instead: + +```bash +curl -fsSL https://raw.githubusercontent.com/BerriAI/litellm/main/model_prices_and_context_window.json | python3 -c ' +import json, sys +for name, row in json.load(sys.stdin).items(): + provider = str(row.get("litellm_provider", "")) if isinstance(row, dict) else "" + if provider.startswith(sys.argv[1]) and row.get("mode") == "chat": + prefix = "bedrock" if provider == "bedrock_converse" else "vertex_ai" if provider.startswith("vertex_ai") else provider + print(name if name.startswith(prefix + "/") else prefix + "/" + name) +' openai +``` + +In `config.yaml`, `model` is a name from that list, as in `openai/gpt-6.1-sol` or `bedrock/us.anthropic.`, and `model_name` is what clients will send. If the folder already has a `config.yaml`, show the user its `model_name` lines and ask before replacing it. This example uses the newest GPT model in the cost map when this skill was written, so replace it with what the user picked: + +```yaml +model_list: + - model_name: gpt-6.1-sol + litellm_params: + model: openai/gpt-6.1-sol + api_key: os.environ/OPENAI_API_KEY + +general_settings: + master_key: os.environ/LITELLM_MASTER_KEY +``` + +Add one entry per model. On Azure, ask the user for each deployment's name and the model it runs. Use `azure/` as `model`, since Azure routes by deployment and a name from the lookup works only when the deployment has that same name, and add `model_info:` with `base_model: azure/` to the entry, since LiteLLM prices each call by that name. Providers that need more than a key, like Azure or Bedrock, list their `litellm_params` on their page under https://docs.litellm.ai/docs/providers. Point every secret at `.env` through `os.environ/NAME` the same way + +## 6. Their own Postgres, on the uv path + +Ask the user to create a new, empty database for LiteLLM on their server (`CREATE DATABASE litellm;`) and add `DATABASE_URL=postgresql://...` for it to `.env` themselves. The proxy creates its tables there on first start and stops on a database that already holds other tables. If that URL goes through a transaction pooler such as PgBouncer, they also add `DIRECT_URL` for the same database without the pooler, which the migrations use. Then add a salt key. It encrypts the provider credentials the proxy stores in the database and falls back to the master key when unset, so set it once and never change it: + +```bash +grep -q '^LITELLM_SALT_KEY=.' .env || printf 'LITELLM_SALT_KEY=sk-%s\n' "$(openssl rand -hex 32)" >> .env +``` + +Generate the Prisma client once inside the tool's environment.

Start the proxy + +Bind to `127.0.0.1` unless the user wants other machines to reach it + +uv, in one shell command that starts with the loader line, since the installed `litellm` does not read `.env` by itself: + +```bash +export PATH="$HOME/.local/bin:$PATH"; export PATH="$(uv tool dir --bin):$PATH" +nohup litellm --config config.yaml --host 127.0.0.1 --port 4000 > litellm.log 2>&1 & +echo $! > litellm.pid +``` + +Docker: + +```bash +docker run -d --name litellm --env-file .env -v "$PWD/config.yaml:/app/config.yaml:ro" -p 127.0.0.1:4000:4000 \ + docker.litellm.ai/berriai/litellm:main-stable --config /app/config.yaml --port 4000 +``` + +Wait on the health route, stopping early if the proxy exits.

The first apply after upgrading the proxy overwrites values set outside Terraform with the configuration's, including `tier`, which defaults to `free`, and `base_model`, which falls back to the deployment name when `pricing_base_model` is unset. Run `terraform plan` before that apply and copy any value to keep into the configuration - **model** (breaking): a key named in `additional_litellm_params.additional_drop_params` is no longer deleted from the deployment's `litellm_params`. A configuration that also sets that key, such as `vertex_location`, stores it on the deployment at its next apply, and the proxy applies the drop list to requests instead. For `vertex_location` this changes routing. `/v1/messages` calls now go to the configured region, while chat completions drop a listed `vertex_location` and use the default region. To keep such a key off a deployment, remove its attribute and replace the model with `terraform apply -replace`, which gives it a new model id, since an update keeps a stored value the provider leaves out. `model`, `custom_llm_provider` and `merge_reasoning_content_in_choices` are always sent. A value that is not a JSON list of names, such as a bare `"store"` or an empty string, now fails the plan, and with it `terraform destroy`, instead of being stored as a string the proxy ignores. Rewrite it as `jsonencode([...])`, or remove the model without fixing it through `terraform destroy -refresh=false` - **key** (breaking): `model_max_budget` on `litellm_key` is now a JSON string of per-model budget objects (`jsonencode({"gpt-4o-mini" = {budget_limit = 50, time_period = "30d"}})`), matching `litellm_user`, `litellm_budget` and `litellm_tag`. The old `map(number)` form sent bare numbers to `/key/generate`, which the proxy rejects with a 500 (`'int' object is not iterable`), so every key with a non-empty `model_max_budget` failed to apply. Existing state upgrades automatically (schema version 1) and the attribute is refilled from the proxy on the next read; configurations still using the map form must be rewritten - **Versioning**: the provider is now published at the LiteLLM version, from the same commit as the proxy, on every LiteLLM release (dev, rc, stable). The `0.x` line ends at `0.4.0`; a `~> 0.4` constraint will not receive further releases, so re-pin to the LiteLLM version your proxy runs (for example `~> 1.99.0`).

Adding a perf test is adding a module with a `CASE` to `perf/cases/`; a new deployment or guardrail is a config change; a new metric is a name in `Metric` plus a branch in `observe.observe` - `other/` - the holding-pen suite for the `other.*` registry cluster with no home of its own yet: the master-key auth gate, JWT auth (access tokens issued by a real Keycloak realm, `idp.py` plus `idp_realm.json`, whose JWKS the proxy's `JWT_PUBLIC_KEY_URL` points at, see CONTRIBUTING.md for the start command and config block), and the process-lifecycle health probes (liveness, public readiness, authenticated readiness diagnostics). Promote a cluster out once it is large/stable enough for its own suite - `secret_manager/` - the gateway's `key_management_system` against a real secret manager: deployment keys resolved from it (`os.environ/` where the name exists only in the manager) and virtual keys written to and deleted from it. The tests are backend-agnostic and each backend is its own lane, because the setting is global to the proxy: `E2E_SECRET_MANAGER=` opts in and picks the backend from `secret_backends.BACKENDS`, the proxy is booted from `gateway/secret_manager__ci_config.yml` against the live manager, and the tests reach that manager through the backend's `SecretStore` (`secret_store_.py`). A test needing something not every backend does carries `requires_capability(...)` and is deselected on lanes that lack it. `secret_manager/backend.sh up ` runs a backend in Docker and writes the proxy's and the tests' env. Marked `secret_manager`, deselected unless `E2E_SECRET_MANAGER` is set, and kept out of the per-PR selector. Backends today: `hashicorp_vault` and `cyberark` (CyberArk Conjur, which cannot delete, so the delete test is Vault-only) - `gateway/` - proxy configuration only (`litellm-config.yml`). No tests -- `claude_code/` - the Claude Code compatibility matrix: drives the real `claude` CLI (and HTTP probes) against a proxy for each feature x provider cell, reporting tagged-union outcomes via the `compat_result` fixture. Ships its own driver/builder/publisher, covered by `tests/e2e_harness/claude_code/`. The HTTP probes ride the shared transport (`ProxyClient.count_tokens` / `ProxyClient.messages`).

Ships its own driver/builder/publisher, covered by `tests/e2e_harness/claude_code/`. The HTTP probes ride the shared transport (`ProxyClient.count_tokens` / `ProxyClient.messages`). The CLI-driving path stays bespoke. `pr_gate_version_resolver.py` only forwards to `cli_harness/npm_version_resolver.py`, because the Buildkite runner images still run that path and install @latest without it +- `cli_harness/` - no tests, only the plumbing every suite that drives a real coding-agent CLI shares: `npm_version_resolver.py` picks the CLI release to install (the newest npm release at least three days old, run by CI as `python tests/e2e/cli_harness/npm_version_resolver.py `, stdlib only), `lockdown.py` gives the CLI subprocess an allowlisted env and a fresh empty HOME so it never sees the runner's credentials or dotfiles, and `rate_limiter.py` is the cross-process token bucket per upstream that keeps parallel CLI runs under one request rate. Covered by `tests/e2e_harness/cli_harness/`. Code only one CLI suite needs stays in that suite +- `codex/` - the Codex compatibility suite: drives the real `codex exec --json` CLI through the gateway, one class per row (the command round trip, a file edit with the patch tool, a long session that follows a chain of files one command at a time, and auto-compaction, where Codex reads a random value, compacts through the gateway and is asked for the value after the file is deleted), each row parametrized over `SETUPS` in `setups.py`, one `pytest.param` per setup (GPT on Bedrock Mantle, Bedrock Runtime, Azure OpenAI and OpenAI, plus Claude on Bedrock). A row with one setup broken by a known bug parametrizes over `with_expected_failure(, reason=...)`, which is `SETUPS` with a strict xfail on that one setup. The `setup` fixture registers that setup's deployment under a fresh name via `/model/new` and the `codex` fixture makes a key scoped to it, and both are deleted on teardown. `harness.py` gives each test a throwaway HOME and CODEX_HOME whose `config.toml` points a custom `responses` provider at the gateway and has Codex read its model list from the gateway's `/v1/models` (`model_catalog_url` on the provider), with the sandbox on (`workspace-write`) and approvals off, and runs the CLI under `cli_harness`'s env lockdown and rate limiter. `run.py` reads the JSONL events into a `CodexRun`: the commands with their output, the patched files, the last agent message as `answer`, the usage and the errors, where an error's `status_code` is what lets the suite's 5xx rerun rule catch a turn Codex gave up on. `codex exec --json` prints nothing when Codex compacts, so `rollout.py` reads the compactions from the thread's rollout file under CODEX_HOME/sessions, and a compaction is remote when its replacement history kept the provider's `compaction` item. `exec` and `resume` take `compact_after_tokens`, which forces Codex's remote compaction (`compaction_trigger` items over `/v1/responses`, the path Codex otherwise only takes for OpenAI and Azure) on the gateway provider and compacts once the context grows past that many tokens. A test passes on a random value the model can only learn through the gateway, never on the model's wording or the exact command it typed. It needs `codex` on PATH and fails without it.
