AIの運用

It covers deployment, data and model versions, resource use, monitoring, incident response, and retirement. A successful training experiment does not establish that the surrounding production workflow will remain dependable.

主なポイント

• Version the full release.
• Check task quality before promotion.
• Assign incident ownership and verify recovery.

Define the service objective and its operating limits. Specify expected inputs, response-time targets, availability needs, and what the service should do when a model or dependency is unavailable. An explicit degraded state is easier to manage than silent substitution of an untested output. Version the complete release: model, data transformations, prompts, retrieval indexes, dependencies, and configuration. Changing one of these can alter behavior even when the public API looks unchanged. Keep a tested route back to the last compatible version. Automate repeatable checks while preserving meaningful release decisions. Validate data contracts, run task evaluations, and test resource limits before rollout. A pipeline that automatically retrains should not automatically promote every new checkpoint without checking quality and compatibility. Assign owners for alerts and failures. Record what happened, which users or outputs were affected, and how recovery was verified. Review recurring incidents for root causes rather than only restarting services. Operational success includes data correctness and task outcomes as well as uptime.

1. Imagine a new model expecting a renamed feature while the old input pipeline is still serving the previous name.
2. Deploying the model alone can break requests even though both components pass their own isolated tests.
3. Package the compatible versions, test the contract end to end, and retain the previous pair for rollback.

The hypothetical release illustrates why AI operations manages a system configuration rather than a model file alone.
