Steps
- Step 1.
Sign in to Mistral AI Studio (console.mistral.ai), open API Keys and create a standard Studio API key. Mistral only shows the full key once. You do not need a separate Codestral key.
- Step 2.
VS Code: open Settings (gear icon) and go to the Providers tab to add Mistral and enter your API key. The extension stores it in your kilo.json config file.
- Step 3.
CLI: set the API key as an environment variable.
Terminalexport MISTRAL_API_KEY="your-api-key" - Step 4.
Or configure it in ~/.config/kilo/kilo.json or ./kilo.json:
JSON{ "provider": { "mistral": { "env": ["MISTRAL_API_KEY"], }, }, } - Step 5.
Then set your default model (docs example shown; swap in a current id such as mistral/mistral-medium-latest):
JSON{ "model": "mistral/mistral-large-latest", }
Caveats
- Kilo's example uses mistral/mistral-large-latest. Per Mistral's docs that alias points to Mistral Large 3 (mistral-large-2512). Mistral describes mistral-medium-3-5 as optimized for agentic and coding use.
- Per Kilo's docs, only mistral-small-2603 and mistral-small-latest get a high reasoning variant, which sends reasoningEffort: "high".
- Kilo's docs say Codestral autocomplete goes through Mistral's FIM API with a standard Studio key at https://api.mistral.ai, or through Kilo Gateway BYOK.
- Devstral 2 (devstral-2512) was retired 2026-07-31 and replaced by mistral-medium-3-5.
