A fixed-version deployment is a deployment method in which the user explicitly locks a specific model version number to ensure stable output behavior; after the model is retired it does not receive automatic migration, and call requests will directly return a model-unavailable error.

UnverifiedSome Azure OpenAI deployments are configured with auto-upgrade rules that automatically route traffic to the recommended replacement model after a model is retired; fixed-version deployments are not migrated automatically, and calls will fail directly after retirement.77% similarUnverifiedRegularly updating the model version in use is itself a necessary maintenance strategy.73% 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.71% similarUnverifiedThe prompt maintenance process for a new model version includes: reading the release notes, running without modifying the prompt to look for regressions, changing only one variable at a time, and keeping the old version until the new prompt is confirmed to perform better.69% similarUnverifiedIf a project has high stability requirements and tends to lock versions, it should compare the same-version notes of @ai-sdk/harness before upgrading, to confirm there are no underlying behavioral changes69% similar
