Does giving AI agents "memory" actually make them smarter?
Often no as memory systems frequently perform worse than having no memory at all. Key takeaways from my @aiDotEngineer World’s Fair talk:
• Ranking > Gating: What you recall drives virtually all performance lift.
• Default recall policies constantly fail to surface context already sitting in the store.
• Rigorous controls matter: Our negative results exposed critical benchmark contamination in current memory evaluations.
Validated across multiple model families (paper coming soon).

So proud of my friend @natolambert 🎉 The RLHF Book is officially out in print (you can follow the journey of how he built it in the open at It's a solid guide to post-training, from someone who actually shipped the models.
Even more excited that he's taking the leap into independent research. If anyone has earned the trust to do open science on his own terms, it's Nathan.
Bonus of the book launch: getting to catch up w @eugeneyan and @corbtt, our "motley crew" from @aiDotEngineer in Seattle
