Mistral provider

You can proxy requests to Mistral AI models through AI Gateway by creating AI Model Provider and AI Model entities. This reference documents all supported AI capabilities, configuration requirements, and provider-specific details needed for proper integration.

AI Gateway automatically routes requests to the appropriate Mistral API endpoints. The following table shows the upstream paths used for each capability.

The following tables show the AI capabilities supported by the Mistral provider when configuring AI Models.

By default, AI Gateway uses the path templates shown in the tables below (e.g., /chat/completions, /embeddings, etc.). To customize these paths, configure the config.paths field in your AI Model entity. Custom paths take the form {configured_path}/{template_path} — for example, if you set a custom path of /v2, requests to /embeddings would be routed to /v2/embeddings.

Text generation

Support for Mistral text generation capabilities:

Embeddings

Support for Mistral embeddings generation:

The base URL is $UPSTREAM_URL.

AI Gateway uses this URL automatically. You only need to configure a URL if you’re using a self-hosted or Mistral-compatible endpoint, in which case set the upstream_url option in your AI Model configuration.

To use Mistral with AI Gateway, configure a new AI Model Provider. You can then access supported AI Models from Mistral.

Here’s a minimal configuration for chat completions:

curl -X POST https://{region}.api.konghq.com/v1/ai-gateways/{AIGatewayId}/model-providers \
    --header "accept: application/json" \
    --header "Content-Type: application/json" \
    --header "Authorization: Bearer $KONNECT_TOKEN" \
    --data '

A target is an entry in the targets array on the AI Model entity, not the AI Model Provider. Beyond the common target options (name, provider, weight), a target routing to Mistral requires:

• format: The request format your endpoint expects. One of ollama or openai.
