Only model access explicitly published by the source is shown, for the named product. Names may refer to families; this is not a complete model catalogue. Not confirmed does not mean unavailable.
Unlimited everyday text is subject to reasonable use and abuse safeguards. Thinking, Pro models and tools have separate limits; this is not unlimited access to every model.
Total context includes system instructions, tools, memory, internal processing and responses. The space available for your input is smaller and can vary.
These are published plan terms. Your account may have different limits; check it for available usage and reset times.
