Warm plans, clear limits

Image models bill against monthly image credits. Lower-cost 1K image models sit in the 1-credit tier; higher-resolution or premium-quality settings step up to protect monthly credit pools.

The tables below list all 61 chat models in the live selector, with provider API reference pricing as we track it in the catalog (usually per 1M tokens). Subscription billing still uses weighted request units; request cost is the flat per-send cost before longer chats, retrieved reads, Canvas, or tool context multiply the total.

OpenAI Pricing, for transparency

All prices shown are per million tokens unless otherwise noted. Serving gpt-4o profitably is challenging given OpenAI's pricing structure.
