Pozorovatelnost AI
AI observability uses measurements and records to understand how an AI application behaves.
Přehled
It connects requests with retrieval, model calls, tools, and final outcomes. The aim is to investigate real behavior without treating a generated explanation as a reliable trace of internal computation.
Klíčové věci
- Connect metrics, traces, and events.
- Measure task outcomes as well as uptime.
- Minimize and protect logged content.
Hluboký ponor
Use complementary signals. Metrics show patterns such as latency, error rate, and resource use. Traces connect stages of a request. Logs describe events that help explain failures or decisions. Stable request and version identifiers make these signals more useful together. Add task-level measurements where possible. A technically successful model call can still return unsupported information or fail to complete the requested action. Track evidence coverage, validation failures, escalations, and verified outcomes alongside transport health. Protect sensitive content in telemetry. Recording every prompt and response can create a new private-data store. Collect the minimum needed for the diagnostic purpose, apply access and retention controls, and prefer redacted or aggregate information where it serves the same need. Make alerts actionable. Identify the owner, relevant threshold, diagnostic context, and recovery procedure. Avoid pages of noisy events that never lead to a decision. Test that a deliberately induced failure appears in the expected signal and that an operator can trace it to the affected release.
Technický přehled
A model’s stated reasoning is not an authoritative execution log. Use actual tool records, timestamps, inputs permitted for logging, and verified state changes to investigate behavior.
Connect a symptom to a dependency
- Imagine users reporting slow answers while model-generation time remains unchanged.
- A request trace shows that document retrieval rose from 100 ms to 2 seconds after an index change.
- Investigate that dependency and confirm recovery with fresh traces rather than replacing the model without evidence.
The invented timings demonstrate the value of connected measurements.

Často kladené otázky
Should I log every prompt for observability?
Not automatically. Determine the diagnostic need and privacy implications, then use appropriate minimization, access, and retention controls.
