Original post

GBrain v0.36.1 just landed on main. It ships something that was an idea from a hackathon team on Saturday: a team created Hindsight which track predictions over time to help you make better ones. This PR is inspired by that submission, and adds first-of-its-kind full evals.

Over time your brain will not just tell you what people thought or said a year ago, but whether they were right.

You could see how this might be useful to me personally. :-)

A brain helps you and your agent think better. Epistemology meets track record.

GBrain is SOTA on LongMemEval out of all known OSS retrieval and memory repos without LLM query rewriting by more than 1%.

It's MIT license and I run it on my own 100k markdown page OpenClaw/Hermes Agent brain.

Any memory system is welcome to run theirs against these evals and I'll publish them alongside.
