HCS-25 (Adapter): Model Tier (Fallback Heuristic) (Informative)

PurposeDirect link to Purpose​

Provide a deterministic fallback score for model catalogs when:

  • the primary benchmark signal is low-coverage, and
  • no other independent eval sources are available.

ContributionDirect link to Contribution​

  • Adapter id: model-tier
  • Contribution mode: conditional
  • Suggested weight: 2
  • Typical applicability: model catalogs when external eval coverage is sparse

Inputs (reference)Direct link to Inputs (reference)​

Reads model identifiers and benchmark-coverage status fields stored under subject.metadata.additional (e.g., OpenRouter coverage indicators and other eval statuses).

Output componentsDirect link to Output components​

  • model-tier.score in [0,100]
