A technical blog post details how to build a more robust health probe for AI agents that rely on LLM providers. The author emphasizes that a simple one-token ping is insufficient and recommends probing the actual task shape, such as a tool-call round trip. It's crucial to check the response body for errors, as gateways can wrap failures in HTTP 200 responses. The post also advises requiring multiple consecutive successful probes to account for saturated free model pools and implementing client-side backoff and retries for mid-run throttles. Finally, it suggests maintaining an ordered list of candidate models rather than hard-coding a single one, and distinguishing between model health and agent competence. AI
