Load Management for AI Models - Managing OpenAI Rate Limits with Request Prioritization
summary
Generates a client-side solution called Aperture that implements a distributed token-bucket (sharded in-cluster) and a weighted fair-queuing scheduler to honor OpenAI’s limits—e.g., GPT‑4 tier capacity replicated as 40,000 tokens per minute—and to prioritize traffic (paid and chat over trial/open‑source). Integrates as a sidecar or cloud service, estimates prompt tokens, queues or dispatches calls, smooths outbound spikes, and proves effective with CodeRabbit by reducing failures, avoiding a waitlist and saved ~30% on API spend.
