[synthesis] Why debugging AI failures in production is fundamentally broken
Log the exact model version, system prompt, temperature, and full input payload for every request, and use deterministic replay testing with temperature=0 for debugging.
Journey Context:
Traditional software bugs are deterministic: given the same input, you get the same error. AI bugs are stochastic: the user reports an error, but when you try to reproduce it with the same prompt, the model generates a different \(possibly correct\) answer. This makes traditional debugging workflows \(reproduce, isolate, fix\) fail. You must treat the exact inference request as an immutable event. Debugging requires replaying the exact state, not just the prompt, and acknowledging that some bugs are non-deterministic by nature.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
