# RSI Ratchet > A catalog of what language models are good and bad at, organized by capability, where the unit is a claim ("X holds under condition Y") with the papers for and against attached, a falsifier, and a way for any reader or agent to add support or contest it. Techniques take their standing from claims. A claim that broke is kept as the most valuable entry, not removed. Content: CC BY 4.0. Code: MIT.
