Mistral La Plateforme free tier

What Mistral La Plateforme's free tier allows

Mistral documents a Free mode (also referred to as the Experiment plan) that lets you activate a workspace and generate an API key without paying, but the public documentation does not currently expose a reachable rate-limit page for it: the tier URL listed in Mistral's own documentation index returns 404 as of the check date. The console is the only authoritative source for the Experiment plan's requests-per-second and tokens-per-minute ceilings.

Checking a Mistral La Plateforme key

The CORS preflight allows any origin to send an Authorization header, so a browser can call this endpoint directly. That was measured against https://api.mistral.ai on 2026-07-25.

So a key can be checked in the browser checker without installing anything. If you would rather not paste a key into a web page, this does the same thing:

#!/usr/bin/env sh
set -eu

: "${MISTRAL_API_KEY:?Set MISTRAL_API_KEY to a key you created yourself at the provider console}"

# Prints the models this key can reach, then the HTTP status on its own line so
# 200, 401, and 429 stay distinguishable.
curl --silent --show-error \
  --write-out '\nHTTP %{http_code}\n' \
  --header "Authorization: Bearer $MISTRAL_API_KEY" \
  'https://api.mistral.ai/v1/models'

Using a Mistral La Plateforme key

Mistral La Plateforme serves the OpenAI chat completions protocol at https://api.mistral.ai/v1. Point any client that accepts a custom base URL at it, and let the client read the key from MISTRAL_API_KEY so the value never lands in a config file:

# Merge this snippet into ~/.codex/config.toml.
# Project-level config cannot select a custom model provider.
model = "mistral-small-latest"
model_provider = "mistral"

[model_providers.mistral]
name = "Mistral La Plateforme OpenAI-compatible gateway"
base_url = "https://api.mistral.ai/v1"
env_key = "MISTRAL_API_KEY"
wire_api = "responses"

Questions about the Mistral La Plateforme free tier

Does Mistral La Plateforme ask for a credit card?

No. Mistral La Plateforme is one of 23 providers here that hand out free access without a card, so the only cost of trying it is the signup.

What are Mistral La Plateforme's free-tier rate limits?

Mistral La Plateforme publishes no single free-tier number: its limits are enforced but not published. This catalog leaves that blank rather than guessing a figure.

What happens when a Mistral La Plateforme key hits the limit?

The endpoint answers 429. That is a statement about the request that was refused, not about how much quota is left; only a reset header from the provider tells you when it clears.

Is the Mistral La Plateforme free tier going away?

Nothing in Mistral La Plateforme's own documentation says so as of 2026-07-25. Mistral's consumer Free plan for the Vibe assistant is a different product from the API Free mode; do not read the assistant's message limits as API limits.

Can Mistral La Plateforme be used with Codex, Cline, or Continue?

Yes. Mistral La Plateforme serves the OpenAI chat completions protocol at https://api.mistral.ai/v1, so any client that accepts a custom base URL can use it. Claude Code is the exception, because it speaks the Anthropic protocol instead.
