+description: "Use Amazon Bedrock Mantle's OpenAI-compatible endpoints through Portkey for chat completions, messages, and responses APIs."
+---
+
+Amazon Bedrock Mantle provides OpenAI-compatible API endpoints for model inference on AWS. Access models from Anthropic, Mistral, NVIDIA, Qwen, DeepSeek, Google, and more through familiar OpenAI SDK patterns.
+
+<Card title="AWS Bedrock Mantle Documentation" href="https://docs.aws.amazon.com/bedrock/latest/userguide/bedrock-mantle.html" />
+
+## Quick Start
+
+<CodeGroup>
+```python Python
+from portkey_ai import Portkey
+
+portkey = Portkey(
+    api_key="PORTKEY_API_KEY",
+    provider="@your-bedrock-mantle-provider"
+)
+
+response = portkey.chat.completions.create(
+    model="mistral.ministral-3-3b-instruct",
+    messages=[{"role": "user", "content": "Hello!"}],
+    max_tokens=50
+)
+
+print(response.choices[0].message.content)
+```
+
+```js JavaScript
+import Portkey from 'portkey-ai'
+
+const portkey = new Portkey({
+    apiKey: "PORTKEY_API_KEY",

+
+## Supported Endpoints
+
+Bedrock Mantle supports four API endpoints. Each model works on specific endpoints based on its provider.
+
+### Chat Completions — `/v1/chat/completions`
+
+Works with non-Anthropic models (Mistral, NVIDIA, Qwen, Google, DeepSeek, MiniMax, Moonshot, Z AI, Writer, OpenAI).
+
+<CodeGroup>
+```python Python
+response = portkey.chat.completions.create(
+    model="mistral.mistral-large-3-675b-instruct",
+    messages=[{"role": "user", "content": "Explain quantum computing in one sentence."}],
+    max_tokens: 100
+)
+```
+
+```js JavaScript
+const response = await portkey.chat.completions.create({
+    model: "mistral.mistral-large-3-675b-instruct",
+    messages: [{ role: "user", content: "Explain quantum computing in one sentence." }],
+    max_tokens: 100
+})
+```
+
+```sh cURL
+curl -X POST "https://api.portkey.ai/v1/chat/completions" \
+  -H "Content-Type: application/json" \
+  -H "x-portkey-api-key: PORTKEY_API_KEY" \
+  -H "x-portkey-provider: bedrock-mantle" \
+  -H "x-portkey-virtual-key: your-virtual-key" \
+  -d '{
+    "model": "mistral.mistral-large-3-675b-instruct",
+    "messages": [{"role": "user", "content": "Explain quantum computing in one sentence."}],
+    "max_tokens": 100
+  }'
+```
+</CodeGroup>
+
+### Messages — `/v1/messages`
+
+Works with Anthropic models. Uses the Anthropic Messages API format.
+
+<CodeGroup>
+```python Python
+import requests
+
+response = requests.post(
+    "https://api.portkey.ai/v1/messages",
+    headers={
+        "Content-Type": "application/json",
+        "x-portkey-api-key": "PORTKEY_API_KEY",
+        "x-portkey-provider": "bedrock-mantle",
+        "x-portkey-virtual-key": "your-virtual-key"
+    },
+    json={
+        "model": "anthropic.claude-opus-4-7",
+        "max_tokens": 100,
+        "messages": [{"role": "user", "content": "Hello, Claude!"}]
+    }
+)
+```
+
+```sh cURL
+curl -X POST "https://api.portkey.ai/v1/messages" \
+  -H "Content-Type: application/json" \
+  -H "x-portkey-api-key: PORTKEY_API_KEY" \
+  -H "x-portkey-provider: bedrock-mantle" \
+  -H "x-portkey-virtual-key: your-virtual-key" \
+  -d '{
+    "model": "anthropic.claude-opus-4-7",
+    "max_tokens": 100,
+    "messages": [{"role": "user", "content": "Hello, Claude!"}]
+  }'
+```
+</CodeGroup>
+
+#### Extended Thinking
+
+<Note>Bedrock Mantle uses `thinking.type: "adaptive"` with `output_config.effort` instead of the standard Anthropic `thinking.type: "enabled"` with `budget_tokens`.</Note>
+
+<CodeGroup>
+```sh cURL
+curl -X POST "https://api.portkey.ai/v1/messages" \
+  -H "Content-Type: application/json" \
+  -H "x-portkey-api-key: PORTKEY_API_KEY" \
+  -H "x-portkey-provider: bedrock-mantle" \
+  -H "x-portkey-virtual-key: your-virtual-key" \
+  -d '{
+    "model": "anthropic.claude-opus-4-7",
+    "max_tokens": 16000,
+    "thinking": {"type": "adaptive"},
+    "output_config": {"effort": "high"},
+    "messages": [{"role": "user", "content": "What is 27 * 453? Think step by step."}]
+  }'
+```
+</CodeGroup>
+
+### Responses — `/v1/responses`
+
+Works with select models (e.g., `openai.gpt-oss-120b`, `openai.gpt-oss-20b`). Supports create, get, and delete operations.
+
+<CodeGroup>
+```sh "Create Response"
+curl -X POST "https://api.portkey.ai/v1/responses" \
+  -H "Content-Type: application/json" \
+  -H "x-portkey-api-key: PORTKEY_API_KEY" \
+  -H "x-portkey-provider: bedrock-mantle" \
+  -H "x-portkey-virtual-key: your-virtual-key" \
+  -d '{
+    "model": "openai.gpt-oss-120b",
+    "input": "Hello! How can you help me today?"
+  }'
+```
+
+```sh "Get Response"
+curl -X GET "https://api.portkey.ai/v1/responses/resp_YOUR_RESPONSE_ID" \
+  -H "x-portkey-api-key: PORTKEY_API_KEY" \
+  -H "x-portkey-provider: bedrock-mantle" \
+  -H "x-portkey-virtual-key: your-virtual-key"
+```
+
+```sh "Delete Response"
+curl -X DELETE "https://api.portkey.ai/v1/responses/resp_YOUR_RESPONSE_ID" \
+  -H "x-portkey-api-key: PORTKEY_API_KEY" \
+  -H "x-portkey-provider: bedrock-mantle" \
+  -H "x-portkey-virtual-key: your-virtual-key"
+```
+</CodeGroup>
+
+### Count Tokens — `/v1/messages/count_tokens`
+
+Count input tokens for Anthropic models without making an inference call.
+
+<CodeGroup>
+```sh cURL
+curl -X POST "https://api.portkey.ai/v1/messages/count_tokens" \
+  -H "Content-Type: application/json" \
+  -H "x-portkey-api-key: PORTKEY_API_KEY" \
+  -H "x-portkey-provider: bedrock-mantle" \
+  -H "x-portkey-virtual-key: your-virtual-key" \
+  -d '{
+    "model": "anthropic.claude-opus-4-7",
+    "system": "You are a scientist",
+    "messages": [{"role": "user", "content": "Hello, Claude"}]
+  }'
+```
+</CodeGroup>
+
+Response:
+```json
+{"input_tokens": 25}
+```
+

+
+## Endpoint-Model Compatibility
+
+Not all models support all endpoints. Use this table as a quick reference:
+
+| Model Family | Chat Completions | Messages | Responses | Count Tokens |
+|-------------|:---:|:---:|:---:|:---:|
+| `anthropic.*` (Claude) | — | Yes | — | Yes |
+| `openai.gpt-oss-120b`, `openai.gpt-oss-20b` | Yes | — | Yes | — |
+| `openai.gpt-oss-safeguard-*` | Yes | — | — | — |
+| `mistral.*` | Yes | — | — | — |
+| `nvidia.*` | Yes | — | — | — |
+| `qwen.*` | Yes | — | — | — |
+| `google.gemma-*` | Yes | — | — | — |
+| `deepseek.*` | Yes | — | — | — |
+| `minimax.*` | Yes | — | — | — |
+| `moonshotai.*` | Yes | — | — | — |
+| `zai.*` | Yes | — | — | — |
+| `writer.*` | Yes | — | — | — |
+
+<Note>Use the `/v1/models` endpoint on Mantle directly to discover the full list of models available in your AWS account and region.</Note>
+
+---
+
+## Streaming
+
+Enable streaming by setting `stream: true`.
+
+<CodeGroup>
+```python "Chat Completions Stream"
+response = portkey.chat.completions.create(
+    model="qwen.qwen3-32b",
+    messages=[{"role": "user", "content": "Tell me a story"}],
+    max_tokens=200,
+    stream=True
+)
+
+for chunk in response:
+    if chunk.choices[0].delta.content:
+        print(chunk.choices[0].delta.content, end="")
+```
+
+```sh "Messages Stream"
+curl -X POST "https://api.portkey.ai/v1/messages" \
+  -H "Content-Type: application/json" \
+  -H "x-portkey-api-key: PORTKEY_API_KEY" \
+  -H "x-portkey-provider: bedrock-mantle" \
+  -H "x-portkey-virtual-key: your-virtual-key" \
+  -d '{
+    "model": "anthropic.claude-opus-4-7",
+    "max_tokens": 200,
+    "stream": true,
+    "messages": [{"role": "user", "content": "Tell me a story"}]
+  }'
+```
+</CodeGroup>
+
+---
+
+## Limitations
+
+- **Not all models support all endpoints.** Each model on Mantle only works on specific endpoints based on its provider family. For example, Anthropic models only work on `/v1/messages`, not `/v1/chat/completions`. See the [compatibility table](#endpoint-model-compatibility) above.
+- **Model availability is account and region specific.** The models available to you depend on your AWS account's access permissions and the region you're using. Some models (e.g., research previews) require explicit allowlisting by AWS.
+- **Extended thinking uses a different format.** Mantle requires `thinking.type: "adaptive"` with `output_config.effort` instead of the standard Anthropic `thinking.type: "enabled"` with `budget_tokens`.
+- **`/v1/responses` input items listing is not supported.** The `GET /v1/responses/:id/input_items` endpoint is not available on Mantle.
+- **Prompt caching minimum threshold.** Anthropic prompt caching on Mantle requires the cached content to meet a minimum token threshold (typically 2048+ tokens). Smaller prompts won't trigger caching.
+
+---
+
+## Supported Models
+
+Model availability depends on your AWS account and region. Discover available models with:
+
+```sh
+curl -X GET "https://bedrock-mantle.us-east-1.api.aws/v1/models" \
+  -H "Authorization: Bearer YOUR_API_KEY"
+```
+
+<Card title="Bedrock Mantle Model List" href="https://docs.aws.amazon.com/bedrock/latest/userguide/bedrock-mantle.html" />

+
+## Supported Regions
+
+| Region | Endpoint |
+|--------|----------|
+| US East (N. Virginia) | `bedrock-mantle.us-east-1.api.aws` |
+| US East (Ohio) | `bedrock-mantle.us-east-2.api.aws` |
+| US West (Oregon) | `bedrock-mantle.us-west-2.api.aws` |
+| Asia Pacific (Mumbai) | `bedrock-mantle.ap-south-1.api.aws` |
+| Asia Pacific (Tokyo) | `bedrock-mantle.ap-northeast-1.api.aws` |
+| Asia Pacific (Jakarta) | `bedrock-mantle.ap-southeast-3.api.aws` |
