What is this error?

Common Causes

  • Exceeded your plan's requests-per-minute (RPM) or tokens-per-minute (TPM) limit
  • Organization or project-level quota exhausted for the billing period
  • Too many concurrent/parallel requests from the same API key
  • LMArena is throttling all users due to high global demand
  • Free tier limits reached — upgrade required for higher throughput

✓ How to Fix It

  1. Check your usage dashboard on LMArena's platform to see current consumption
  2. Implement exponential backoff: wait 1s after first 429, then 2s, 4s, 8s
  3. Reduce concurrency — send fewer parallel requests
  4. Use batching or queuing to spread requests over time
  5. Consider upgrading your plan for higher rate limits
  6. If available, use LMArena's batch/async API for non-urgent requests
