Model Capabilities Caching
EntryKind: in v2.1.77,
ChangesSection of the release
What
Model capability definitions are now cached locally in a model-capabilities.json file, reducing redundant fetches.
Details
- Capabilities are written to disk and reused across sessions
- Cache-change detection skips unnecessary writes:
"[modelCapabilities] cache unchanged, skipping write" - Graceful fallback on fetch failure:
"[modelCapabilities] fetch failed:"
Evidence
Cache file handling (search for "model-capabilities.json")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
