I want to use the free AI model "Mistral Moderation 2" from Mistral (model id: mistral-moderation-2603) in my project.
Please:
1. Check the provider docs and give me the exact steps to get a free API key.
2. Give me a minimal working example that reads the key from an environment variable.

Before you ship on it

  • In Free mode Mistral may train on your inputs and outputs unless you switch it off in Admin > Privacy, and the actual limits and covered models are not published.
  • Prompts on the free tier may be used to train models. Keep customer data off it.
  • Mistral AI Commercial Terms of Service (effective 25 Sep 2026) apply; they contain no clause specific to Free mode. The help center says Free mode 'has the lowest limits, intended for evaluation and prototyping'. No…
  • Free tiers are shared capacity: treat the limits as a ceiling, not a promise, and keep a paid fallback.
