Streaming tool results
Tool output streams back to the model as it arrives, so a slow search no longer blocks the next token.
Tools used to return their result in one piece. If a search took two seconds, the model sat idle for two seconds.
What changed
Tool results now stream back in chunks. The model can start reading the first rows while the rest are still arriving. Existing tools keep working; streaming starts when a tool sends chunked output.
The console marks streamed results with a thin bar, so you can see when the model started reading.
