LLM Gateway Implementation Reveals New Failure Modes for Apps

By PulseAugur Editorial · [1 sources] ·

Implementing an LLM gateway in front of an application introduces new failure points compared to traditional REST proxies. Issues arise from streaming buffer stalls, mismatches in prefill timeouts, and the splitting of mid-stream failovers. Standard proxies can delay the time to first token by buffering Server-Sent Events (SSE), potentially causing clients to drop connections. Retrying model requests without proper token-aware backoff can lead to rate-limit issues and context window rejections from providers. AI
