# Mistral Rate Limits ## Overview Rate limit management for Mistral AI API. Mistral enforces per-workspace RPM (requests/minute) and TPM (tokens/minute) limits that vary by usage tier (Experiment free tier vs Scale pay-as-you-go). View your workspace limits at [admin.mistral.ai/plateforme/limits](https://admin.mistral.ai/plateforme/limits). ## Prerequisites - Mistral API key configured - Understanding of workspace tier (Experiment vs Scale) - Application with retry infrastructure ## Mistral Rate Limit Architecture Limits are set at the **workspace** level, not per key. All API keys in a workspace share the same RPM/TPM budget. | Endpoint | What's limited | |----------|---------------| | `/v1/chat/completions` | RPM + TPM (input + output) | | `/v1/embeddings` | RPM + TPM (input only) | | `/v1/fim/completions` | RPM + TPM | | `/v1/moderations` | RPM | **Headers returned on every response:** - `x-ratelimit-limit-requests` — your RPM cap - `x-ratelimit-remaining-requests` — remaining RPM - `x-ratelimit-limit-tokens` — your TPM cap - `x-ratelimit-remaining-tokens` — remaining TPM - `Retry-After` — seconds to wait (on 429 only) ## Instructions ### Step 1: Token-Aware Rate Limiter ```typescript class MistralRateLimiter { private requestTimes: number[] = []; private tokenBuckets: Array<{ time: number; tokens: number }> = []; private readonly rpm: number; private readonly tpm: number; constructor(rpm: number, tpm: number) { this.rpm = rpm; this.tpm = tpm; ...
