Bugfixes

  • Default provider header timeouts to five minutes so slow model startups fail less often.
  • Default streamed chunk timeouts to five minutes, with false supported to disable them.
  • Let Anthropic thinking.blockBinding opt out via config when you need to keep the provider default. (@dkindlund)
  • Limit Anthropic thinking block binding to Claude 5.1+ models so older deployments do not reject requests.
  • Avoid unhandled errors when canceling timed-out SSE reads. (@AlexanderWillner)
