Full changelog

What's new

evalview model-check — closed-model drift detection

Detect silent drift in closed-weight models (Anthropic in v1; OpenAI/Mistral/Cohere in v1.1) by running a small structural canary suite directly against the provider.

  • Two-anchor comparison (reference + previous)
  • Dry-run cost estimation
  • Per-provider fingerprint strength labeling
  • Custom suites via --suite
  • Suite-hash enforcement for rotation safety
  • Pinned temperature=0.0 / top_p=1.0 for stable drift signal

Bundled canary suite

15 structural prompts across four scorer families: tool choice, JSON schema, refusal, exact match. Versioned, hash-pinned, rotated via held-out companion suite.

New internals

  • DriftKind + DriftConfidence enums — unified drift taxonomy
  • model_snapshots — timestamped store with auto-pin first-run reference and pruning
  • model_check_scoring — pure-function structural scorers (no LLM judge dependency)
  • model_provider_runner — single-shot completions with per-provider fingerprint capture
  • anthropic adapter registered in adapter_factory
  • TraceDiff gains drift_kind and drift_confidence fields

Tests

80 net new tests covering snapshot store (16), structural scorers (29), canary suite loader (13), and command integration (22) — all mocked, no real API calls in CI.

Install / upgrade:

pip install evalview==0.6.2
