Unverified50% confidenceSolutionExact time
When debugging production Agent failures, you should log the model version and temperature parameter of each call, because model providers silently update models, and without version logs there is no way to correlate model changes with failures.

UnverifiedModel providers frequently perform silent updates to adjust model weights, safety filters, or system-level prompts, but often without explicit changelogs, leaving users unable to track changes or roll back.70% similarUnverified模型版本号本身不等同于质量保证，中转服务可能实际调用蒸馏、量化或参数裁剪的衍生版本，用户难以从外部验证67% similarUnverifiedModel parameters from different generations or base versions are not interchangeable, and the complete version number must be locked down when comparing results.66% similarUnverifiedVendors such as OpenAI and Anthropic continuously update their models, and the same prompt may produce different answers under different versions, so model version numbers need to be recorded to distinguish optimization effects from changes brought by model updates.66% similarUnverifiedMitigating prompt drift requires pinning the LLM version and parameters, recording the full prompt and response for every step, and running regression tests; but silent updates from model vendors and changes in tool return formats also cause drift, so prompts, model versions, parameters, and tool schemas should be versioned together as one set of immutable configuration.65% similar
