LLM rate limiting must account for variable API costs, not just request counts

Developers building applications with large language models (LLMs) face unique challenges with traditional rate limiting. Standard request-per-second limits are insufficient because LLM API calls vary drastically in cost and processing time, from a few cents to dollars and seconds. A naive approach can lead to budget overruns and unfair resource allocation, where one expensive call blocks many cheaper ones. Effective LLM rate limiting requires a cost-aware or resource-aware strategy that assigns 'cost units' based on tokens, monetary value, or estimated processing time, rather than just request counts.

影响 Developers need to implement cost-aware rate limiting for LLM APIs to manage budgets and ensure fair resource allocation.
