perProvider

Without constraints, recommend() might return all results from a single provider because that provider’s models scored highest. perProvider() creates a constraint that spreads results across providers.

function perProvider(max?: number): Constraint

Default: 1 per provider.

Parameter	Type	Default	Description
max	number	1	Maximum models per provider.

import { recommend, Purpose, perProvider } from "pickai";

const results = recommend(models, Purpose.Quality, {
  constraints: [perProvider(2)],
  limit: 10,
});

See Constraints for the two-pass algorithm and custom constraint examples.
