LLM routers struggle with rate limits and response format drift

作者 PulseAugur 编辑部 · [2 个来源] ·

A recent analysis highlights two critical failure modes in multi-provider LLM routing systems that can lead to unexpected costs and downtime. One issue involves how routers incorrectly handle rate limit errors, applying short cooldowns to long-term quota exhaustion, which wastes significant resources. Another problem arises from subtle but impactful differences in how various LLM providers format their responses, such as inconsistent JSON structures or tokenization counts, which can break parsing logic and inflate costs.
