Mistral AI provides powerful language models through an OpenAI-compatible API. docker-agent includes built-in support for Mistral as an alias provider.

​

  2. Set the environment variable:
export MISTRAL_API_KEY="your-api-key"

Thinking budget

Mistral models support thinking mode with effort level strings. The default effort is medium. 
models:
  mistral:
    provider: mistral
    model: mistral-large-latest
    thinking_budget: high  # minimal | low | medium | high | none
To disable thinking: 
models:
  mistral:
    provider: mistral
    model: mistral-large-latest
    thinking_budget: none

​
Auto-detection

When running docker agent run without a config file, docker-agent automatically detects available providers. If MISTRAL_API_KEY is set and higher-priority providers (OpenAI, Anthropic, Google) are not configured, Mistral is selected with mistral-small-latest as the default model.

​
How it works

Mistral is a built-in alias provider:
  • API type: openai_chatcompletions
  • Base URL: https://api.mistral.ai/v1
  • Token variable: MISTRAL_API_KEY
