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.

NVIDIA's exact route page advertises a free API endpoint. Separately, the supplied successful test at 2026-11-05T18:45:35+00:00 establishes access without a top-up using the dedicated account that had never held credit or linked a payment method. Continued availability and quotas are not established.

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

NVIDIA's exact route explicitly links Google's gemma-4-31B-it instruction checkpoint, establishing the advertised identity already shared by the supplied Google, Cline, Kilo and OpenRouter entries. Serving settings and pinned revisions are not assumed identical.
