About this model

Corollary's literature layer searches Europe PMC live and returns papers with full provenance. When an LLM provider is configured, PaperQA2's Crow agent synthesises an answer over the retrieved passages; without one, you still get the ranked, citable evidence set — the platform never fabricates a reference.

Standardized I/O contract

Every model in the Hub speaks the same contract, which is what lets the Router and the agent call any of them without special-casing.
