> Frontier models are much better at verifying their own work first.

> However, we did find useful context-sharing strategies across parallel agents that actually do speed up time to the next breakthrough (in the frontier research rewound benchmark and the current best kappa).

> I submitted a new best bound this morning within 10 minutes using this method, with Astra high coordinating a fleet of agents.

> Strategies to solve the "local minima" problem, like RSI-top, fork and flush, and "forgetting," are now implemented in our open auto-research agent:

> 1) Forgetting seems to be one solution to the "local minima" problem: agents stop getting stuck in idea wells.
> 
> 2) For some tasks, like Integer Mult, we may need the maintainer to specify the scoring mechanism. Most submissions score 0, yet negative research is still helpful.

> I'm also working on our new model release, so it feels like we have a big research lab here, running queued experiments across multiple tracks and projects. :)
