Release Notes
50% Faster Search Agent Amp's search subagent is now 50% faster. We switched the model powering the finder subagent to Haiku 4.5. In our evaluations and usage, this resulted in an approximate 50% speedup with no noticeable loss in quality. This means less waiting for Amp to uncover the relevant context. The search agent should be around 3X cheaper now, as well. Happy (speedy) hacking!
