codex - 💡(How to fix) Fix Frequent 429 Rate Limit errors when using Codex with Spec-kit for automated development. [3 comments, 2 participants]

See error: The process fails with a 429 Rate Limit error (often related to RPM or TPM limits).

TL;DR

Implement rate limiting or exponential backoff in the Spec-kit workflow to handle HTTP 429 errors from Codex.

Guidance

• Verify the rate limits imposed by Codex on the number of requests per minute (RPM) or transactions per minute (TPM) to understand the threshold that's being exceeded.
• Introduce a delay between consecutive requests to Codex to reduce the request frequency and avoid hitting the rate limit.
• Consider implementing an exponential backoff strategy to dynamically adjust the delay between requests based on the number of consecutive 429 errors encountered.
• Review the Spec-kit configuration to see if there are any settings that can be adjusted to reduce the number of requests made to Codex during the automation process.

Notes

The exact implementation details of rate limiting or exponential backoff may vary depending on the programming language and framework used by Spec-kit.

Recommendation

Apply workaround: Implement rate limiting or exponential backoff in the Spec-kit workflow to handle HTTP 429 errors from Codex, as this will allow the automation process to continue without being interrupted by rate limit errors.
