+# Mistral AI
+
+[Mistral AI](https://mistral.ai/)  is a research lab building the best open source models in the world.
+
+Mistral AI offers both premier models and free models, driving innovation and convenience for the developer community. Mistral AI models are state-of-the-art for their multilingual, code generation, maths, and advanced reasoning capabilities.
+
+## Installation
+
+Mistral API is configured as an optional dependency in Strands Agents. To install, run:
+
+```bash
+pip install 'strands-agents[mistral]'
+```
+
+## Usage
+
+After installing `mistral`, you can import and initialize Strands Agents' Mistral API provider as follows:
+
+```python
+from strands import Agent
+from strands.models.mistral import MistralModel
+from strands_tools import calculator
+
+model = MistralModel(
+    api_key="<YOUR_MISTRAL_API_KEY>",
+    # **model_config
+    model_id="mistral-large-latest",
+)
+
+agent = Agent(model=model, tools=[calculator])
+response = agent("What is 2+2")
+print(response)
+```
+
+## Configuration
+
+### Client Configuration
+
+The `client_args` configure the underlying Mistral client. You can pass additional arguments to customize the client behavior:
+
+```python
+model = MistralModel(
+    api_key="<YOUR_MISTRAL_API_KEY>",
+    client_args={
+        "timeout": 30,
+        # Additional client configuration options
+    },
+    model_id="mistral-large-latest"
+)
+```
+
+For a complete list of available client arguments, please refer to the Mistral AI [documentation](https://docs.mistral.ai/).
+
+### Model Configuration
+
+The `model_config` configures the underlying model selected for inference. The supported configurations are:
+
+| Parameter | Description | Example | Options |
+|-----------|-------------|---------|---------|
+| `model_id` | ID of a Mistral model to use | `mistral-large-latest` | [reference](https://docs.mistral.ai/getting-started/models/) |
+| `max_tokens` | Maximum number of tokens to generate in the response | `1000` | Positive integer |
+| `temperature` | Controls randomness in generation (0.0 to 1.0) | `0.7` | Float between 0.0 and 1.0 |
+| `top_p` | Controls diversity via nucleus sampling | `0.9` | Float between 0.0 and 1.0 |
+| `stream` | Whether to enable streaming responses | `true` | `true` or `false` |
+
+## Environment Variables
+
+You can set your Mistral API key as an environment variable instead of passing it directly:
+
+```bash
+export MISTRAL_API_KEY="your_api_key_here"
+```
+
+Then initialize the model without the API key parameter:
+
+```python
+model = MistralModel(model_id="mistral-large-latest")
+```
+
+## Troubleshooting
+
+### Module Not Found
+
+If you encounter the error `ModuleNotFoundError: No module named 'mistralai'`, this means you haven't installed the `mistral` dependency in your environment. To fix, run `pip install 'strands-agents[mistral]'`.
