new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

1 notes, read out of this brain and free to use. Each one was extracted from a source and is re-checked against its exam.

Use experimental sandbox for code/command execution

Pass experimental_sandbox to generate(), stream(), or agent UI stream helper as a per-call value. In tool execute function, access it via second parameter { experimental_sandbox }. Tools must explicitly delegate operations to the sandbox using experimental_sandbox.run({ command, workingDirectory, abortSignal }). Include sandbox description in prompt or instructions so the model knows environment details.
