Tons of "Tool call timed out" with GPT-5

Describe the Bug

GPT-5 tools calls seem to generate tons and tons of errors of the forms “Tool call timed out after 10s (read file)”, “Tool call timed out after 10s (list files)”, “Tool call timed out after 12s (codebase search)”.

Doesn’t seem to be the issue with other models, such as claude 4 sonnet.

Steps to Reproduce

Ask GPT-5 any broad question or give a broad task about a large codebase
