fix(merge): resolve conflict with main in cost_tracking_settings

Browse source 
PR #22890 used cast(str, ...) / cast(Optional[str], ...) for the return
statements; this PR's approach uses str() for explicit runtime coercion
(addressing Greptile's concern). Keep the str() version and drop the
now-unused cast import.

# v1/messages → /responses Parameter Mapping
When you send a request to `/v1/messages` targeting an OpenAI or Azure model, LiteLLM internally routes it through the OpenAI Responses API. This page documents exactly how every parameter gets translated in both directions.
The transformation lives in `litellm/llms/anthropic/experimental_pass_through/responses_adapters/transformation.py`.
## Request: Anthropic → Responses API
### Top-level parameters
| Anthropic (`/v1/messages`) | Responses API | Notes |
|---|---|---|
| `model` | `model` | Passed through as-is |
| `messages` | `input` | Structurally transformed — see the messages section below |
| `system` (string) | `instructions` | Passed as a plain string |
| `system` (list of content blocks) | `instructions` | Text blocks are joined with `\n`; non-text blocks are ignored |
| `max_tokens` | `max_output_tokens` | Renamed |
| `temperature` | `temperature` | Passed through as-is |
| `top_p` | `top_p` | Passed through as-is |
| `tools` | `tools` | Format-translated — see the tools section below |
| `tool_choice` | `tool_choice` | Type-remapped — see the tool_choice section below |
| `thinking` | `reasoning` | Budget tokens mapped to effort level — see the thinking section below |
| `output_format` or `output_config.format` | `text` | Wrapped as `{"format": {"type": "json_schema", "name": "structured_output", "schema": ..., "strict": true}}` |
| `context_management` | `context_management` | Converted from Anthropic dict to OpenAI array format — see the context_management section below |
| `metadata.user_id` | `user` | Extracted from the metadata object and truncated to 64 characters |
| `stop_sequences` | ❌ Not mapped | Dropped silently |
| `top_k` | ❌ Not mapped | Dropped silently |
| `speed` | ❌ Not mapped | Only used to set Anthropic beta headers on the native path |
### How messages get converted
Each Anthropic message is expanded into one or more Responses API input items. The key difference is that `tool_result` and `tool_use` blocks become **top-level items** in the input array rather than being nested inside a message.
| Anthropic message | Responses API input item |
|---|---|
| `user` role, string content | `{"type": "message", "role": "user", "content": [{"type": "input_text", "text": "..."}]}` |
| `user` role, `{"type": "text"}` block | `{"type": "input_text", "text": "..."}` inside a user message |
| `user` role, `{"type": "image", "source": {"type": "base64"}}` | `{"type": "input_image", "image_url": "data:<media_type>;base64,<data>"}` inside a user message |
| `user` role, `{"type": "image", "source": {"type": "url"}}` | `{"type": "input_image", "image_url": "<url>"}` inside a user message |
| `user` role, `{"type": "tool_result"}` block | Top-level `{"type": "function_call_output", "call_id": "...", "output": "..."}` — pulled out of the message entirely |
| `assistant` role, string content | `{"type": "message", "role": "assistant", "content": [{"type": "output_text", "text": "..."}]}` |
| `assistant` role, `{"type": "text"}` block | `{"type": "output_text", "text": "..."}` inside an assistant message |
| `assistant` role, `{"type": "tool_use"}` block | Top-level `{"type": "function_call", "call_id": "<id>", "name": "...", "arguments": "<JSON string>"}` — pulled out of the message entirely |
| `assistant` role, `{"type": "thinking"}` block | `{"type": "output_text", "text": "<thinking text>"}` inside an assistant message |
### tools
| Anthropic tool | Responses API tool |
|---|---|
| Any tool where `type` starts with `"web_search"` or `name == "web_search"` | `{"type": "web_search_preview"}` |
| All other tools | `{"type": "function", "name": "...", "description": "...", "parameters": <input_schema>}` |
### tool_choice
| Anthropic `tool_choice.type` | Responses API `tool_choice` |
|---|---|
| `"auto"` | `{"type": "auto"}` |
| `"any"` | `{"type": "required"}` |
| `"tool"` | `{"type": "function", "name": "<tool name>"}` |
### thinking → reasoning
The `budget_tokens` value is mapped to a string effort level. `summary` is always set to `"detailed"`.
| `thinking.budget_tokens` | `reasoning.effort` |
|---|---|
| >= 10000 | `"high"` |
| >= 5000 | `"medium"` |
| >= 2000 | `"low"` |
| < 2000 | `"minimal"` |
If `thinking.type` is anything other than `"enabled"`, the `reasoning` field is not sent at all.
### context_management
Anthropic uses a nested dict with an `edits` array. OpenAI uses a flat array of compaction objects.
```
Anthropic input:
{
"edits": [
{
"type": "compact_20260112",
"trigger": {"type": "input_tokens", "value": 150000}
}
]
}
Responses API output:
[
{"type": "compaction", "compact_threshold": 150000}
]
```
## Response: Responses API → Anthropic
When the Responses API reply comes back, LiteLLM converts it into an Anthropic `AnthropicMessagesResponse`.
| Responses API field | Anthropic response field | Notes |
|---|---|---|
| `response.id` | `id` | |
| `response.model` | `model` | Falls back to `"unknown-model"` if missing |
| `ResponseReasoningItem` — `summary[*].text` | `content` block `{"type": "thinking", "thinking": "..."}` | Each non-empty summary text becomes a thinking block |
| `ResponseOutputMessage` — `content[*]` where `type == "output_text"` | `content` block `{"type": "text", "text": "..."}` | |
| `ResponseFunctionToolCall` — `{call_id, name, arguments}` | `content` block `{"type": "tool_use", "id": "...", "name": "...", "input": {...}}` | `arguments` is JSON-parsed back into a dict |
| Any `function_call` present in output | `stop_reason: "tool_use"` | |
| `response.status == "incomplete"` | `stop_reason: "max_tokens"` | Takes precedence over the default |
| Everything else | `stop_reason: "end_turn"` | Default |
| `response.usage.input_tokens` | `usage.input_tokens` | |
| `response.usage.output_tokens` | `usage.output_tokens` | |
| *(hardcoded)* | `type: "message"` | Always set |
| *(hardcoded)* | `role: "assistant"` | Always set |
| *(hardcoded)* | `stop_sequence: null` | Always null on this path |

# Amazon Bedrock Mantle
[Amazon Bedrock Mantle](https://docs.aws.amazon.com/bedrock/latest/userguide/bedrock-mantle.html) is Amazon Bedrock's distributed inference engine (Project Mantle) that exposes an **OpenAI-compatible API** for Bedrock-hosted models.
Use this provider to call Bedrock Mantle models with accurate **AWS Bedrock pricing** instead of OpenAI pricing.
:::tip
**We support ALL Bedrock Mantle models, just set `model=bedrock_mantle/<model-id>` as a prefix when sending litellm requests**
:::
## API Key
```python
# env variable
os.environ['BEDROCK_MANTLE_API_KEY'] = "your-aws-bedrock-api-key"
# optional: override region (defaults to us-east-1)
os.environ['BEDROCK_MANTLE_REGION'] = "us-east-1" # or use AWS_REGION
```
## Supported Models
| Model | Context Window | Input (per 1M tokens) | Output (per 1M tokens) |
|-------|---------------|----------------------|------------------------|
| `openai.gpt-oss-120b` | 131K | $0.15 | $0.60 |
| `openai.gpt-oss-20b` | 131K | $0.075 | $0.30 |
| `openai.gpt-oss-safeguard-120b` | 131K | $0.15 | $0.60 |
| `openai.gpt-oss-safeguard-20b` | 131K | $0.075 | $0.30 |
## Sample Usage
<Tabs>
<TabItem value="sdk" label="SDK">
```python
from litellm import completion
import os
os.environ['BEDROCK_MANTLE_API_KEY'] = "your-bedrock-api-key"
response = completion(
model="bedrock_mantle/openai.gpt-oss-120b",
messages=[{"role": "user", "content": "hello from litellm"}],
)
print(response)
```
</TabItem>
<TabItem value="streaming" label="Streaming">
```python
from litellm import completion
import os
os.environ['BEDROCK_MANTLE_API_KEY'] = "your-bedrock-api-key"
response = completion(
model="bedrock_mantle/openai.gpt-oss-120b",
messages=[{"role": "user", "content": "hello from litellm"}],
stream=True,
)
for chunk in response:
print(chunk)
```
</TabItem>
<TabItem value="async" label="Async">
```python
import asyncio
from litellm import acompletion
import os
os.environ['BEDROCK_MANTLE_API_KEY'] = "your-bedrock-api-key"
async def main():
response = await acompletion(
model="bedrock_mantle/openai.gpt-oss-120b",
messages=[{"role": "user", "content": "hello from litellm"}],
)
print(response)
asyncio.run(main())
```
</TabItem>
</Tabs>
## Region Configuration
The API base URL is `https://bedrock-mantle.{region}.api.aws/v1`. Region is resolved in this order:
1. `BEDROCK_MANTLE_REGION` env var
2. `AWS_REGION` env var
3. Default: `us-east-1`
**Supported regions:** `us-east-1`, `us-east-2`, `us-west-2`, `eu-west-1`, `eu-west-2`, `eu-central-1`, `eu-south-1`, `eu-north-1`, `ap-northeast-1`, `ap-south-1`, `ap-southeast-3`, `sa-east-1`
```python
import os
os.environ['BEDROCK_MANTLE_REGION'] = "eu-west-1"
# or pass api_base directly
response = completion(
model="bedrock_mantle/openai.gpt-oss-120b",
messages=[{"role": "user", "content": "hello"}],
api_base="https://bedrock-mantle.eu-west-1.api.aws/v1",
)
```
## Usage with LiteLLM Proxy
### 1. Set Bedrock Mantle models on config.yaml
```yaml
model_list:
- model_name: gpt-oss-120b
litellm_params:
model: bedrock_mantle/openai.gpt-oss-120b
api_key: os.environ/BEDROCK_MANTLE_API_KEY
# optional region override:
api_base: "https://bedrock-mantle.us-east-1.api.aws/v1"
- model_name: gpt-oss-20b
litellm_params:
model: bedrock_mantle/openai.gpt-oss-20b
api_key: os.environ/BEDROCK_MANTLE_API_KEY
```
### 2. Start the proxy
```shell
litellm --config /path/to/config.yaml
```
### 3. Send a request
```python
import openai
client = openai.OpenAI(
api_key="anything",
base_url="http://0.0.0.0:4000",
)
response = client.chat.completions.create(
model="gpt-oss-120b",
messages=[{"role": "user", "content": "hello from litellm"}],
)
print(response)
```
