OpenRouter published a tutorial explaining how to read the 429 response header and determine the rate limit source based on limit_source, providing three repair methods: retry, model fallback, and vendor failover.
Why it matters: The author used the same batch of 60 requests to test three 429 handling methods, providing a comparison of time consumption and cost, which can be directly migrated to your own retry logic.
