 # Changelog
 
+## [Unreleased]
+
+### Fixed
+
+- The key notes were out of date. Cerebras is no longer free: it gives a $5 trial for 30 days and asks for a card. Mistral has a free plan with $10 a month in API credits, not the old Experiment plan. Groq's free plan allows 8K tokens a minute. `anus setup` and the README now say so, and warn that free tiers may use what you send to improve their models.

 ## How "free" works

 - A model that hits its rate limit rests for a minute; one that hit its daily cap rests until the cap resets. The request moves on without waiting.
 - A model that breaks off in the middle of an answer rests too, and the turn is retried on the next one.
 - The footer shows which model answered. Type `/free` to see the whole list: awake, resting, or no key.
+- Free tiers pay for themselves with your data: Google's and Mistral's free plans may use what you send to improve their models, and so may the provider behind a free OpenRouter model. Keep secrets out of the folder you run ANUS in.
 - ANUS uses only the keys you gave it in `anus setup`. Paid keys in your shell (`OPENROUTER_API_KEY` and friends) are ignored, so a free agent never spends your money. `ANUS_ENV_KEYS=1` lets it use them.
