Free aggregator routes

These are the aggregator routes recorded in the current or last published catalog. Each route keeps its exact model ID and thinking information.

Limits above: Kilo. Available gateway routes are listed below.

The supplied Kilo catalog snapshot records stealth/cat-jam. Vercel's official announcement independently identifies that exact public alias as a stealth coding and reasoning model. OpenCode's official documentation identifies cat-jam-free as Cat Jam Free, a stealth model. These support the Cat Jam public display family, but do not disclose a creator or establish identical checkpoints; duplicate_key remains route-specific.
