Frequently Asked Questions

What are typical LLM rate limits?
Anthropic Tier 1: 50 RPM Opus, 1000 RPM Haiku. OpenAI Tier 1: 500 RPM. Tier 4 / Enterprise can be 10K+ RPM. Provider dashboards show your exact limits.
How do I survive a burst?
Three strategies: (1) round-robin between API keys / providers, (2) queue requests with exponential backoff, (3) cache top queries to dodge LLM entirely.
TPM vs RPM?
Tokens-per-minute usually hits before RPM. A 200K-token request burns the TPM budget instantly even at 1 RPM. Most production hits are TPM, not RPM.
