Mistral La Plateforme (Experiment tier)
Free Experiment tier across all Mistral models, phone verify instead of a card
Mistral's developer platform (La Plateforme) offers a free Experiment tier that grants rate-limited access to the full model lineup, including Mistral Large, the Small models, and Codestral. Onboarding needs a verified phone number rather than a credit card, and the API is OpenAI-compatible.
Free tier
Free Experiment tier for evaluation and prototyping; no credit card, phone verification required. A ~1B tokens/month evaluation allowance is commonly cited. Move to paid usage tiers for production rate limits.Rate limits
Free-mode limits are intentionally modest and enforced as requests-per-second, tokens-per-minute, and tokens-per-month independently; exact values appear in your admin console (admin.mistral.ai limits page).Auth
