On-Device Summaries: CI Evals Without Fake Confidence

Summary

Current CI evaluations for NoteSummary often only confirm schema validity, failing to verify if the actionItem accurately reflects the decision made in the note. A more effective continuous integration (CI) evaluation strategy for on-device summaries should focus on a narrower claim. This involves running curated note fixtures through the actual summary path used by the screen. The evaluation should score only crisp, screen-specific failure modes using boolean rules. Furthermore, every successful "green" run must be meticulously labeled by the model version, the specific fixture set used, and the scoring-rule version. This approach clarifies that a "green" result signifies only that known fixtures passed a narrow, versioned gate, not that the summary quality is inherently high.

Key takeaway

For MLOps Engineers managing on-device summary pipelines, you should refine your CI evaluations beyond mere schema validation. Focus on testing specific, screen-relevant failure modes using curated fixtures and boolean rules. Ensure every successful CI run is meticulously tagged with the model, fixture, and rule versions. This approach provides clear, versioned gates, preventing false confidence in summary quality and ensuring your CI truly reflects functional correctness for specific use cases.

Key insights

CI evaluations for on-device summaries should validate specific failure modes, not just schema, to ensure meaningful results.

Principles

• Narrow CI claims to screen-specific failures.
• Label green runs with model, fixture, rule versions.
• Schema validity does not equal summary quality.

Method

Run curated note fixtures through the screen's summary path, scoring crisp screen-specific failure modes with boolean rules, and label successful runs by model, fixture set, and scoring-rule version.

In practice

• Use curated note fixtures for testing.
• Implement boolean rules for failure modes.
• Version control all CI evaluation components.
