Claude Opus 5.5, GPT-6 Sol and Luna, and Grok 4.7 arrive

We moved the catalog to the newest generation of each frontier model family, and saved selections followed on their own: a workflow, app, or specialist that names a retired model now runs on its successor, so nothing had to be re-saved. Subscription models through Token Tunnel follow the same upgrades. Compare everything on the models page.

Auto

Each tier starts cheap on the cost-to-intelligence frontier and falls back across four providers (OpenAI, Anthropic, Google, xAI), so one provider's outage can't take a tier down. When one of your own subscription models is online, Auto uses it in place of the tier's cloud model.
