He's talking about llama 2 superhots, and mistral derivatives that can be uncensored
Derivatives are dervied from those base models
Unsensored being obvious I hope
Superhots are a derived model (for llama only? Not sure) using a certain technique for fine tuning and context length. A Google will reveal the paper and research.
One angle people aren't considering is that that restraining LLMs is our first alignment project. Putting aside whether we should try to restrain LLMs, it's an interesting question in itself (regarding safety) if we technically struggle to do that.
