agent.iteration_limit
What happened
Section titled “What happened”The assistant reached the maximum number of steps without a clear answer. Please rephrase the request or split it into smaller steps.
Technical background
Section titled “Technical background”UnprocessableError from the agent loop: the run hit its maximum round
count before the model produced a final answer — usually a tool that keeps
returning the same error, or a task that needs more steps than the limit
allows.
Raise the round limit for the run, or narrow the task. The conversation’s turn history shows which tool call kept repeating.
