Claude.ai, ChatGPT, etc. are finished B2C products. They're black boxes, encapsulated experiences. Consumers don't want to pick a model, or know what model they're using; they just want to "talk to AI", and for the system to know which model is best to answer any given question. I would bet that for these companies, if their frontend observes you using the little model override button, that gets instrumented as an "oops" event in their metrics — something they aim to minimize. What you're looking for, are the landing pages of the B2B API products underlying these B2C experiences. That would be https://www.anthropic.com/claude https://www.anthropic.com/claude, https://openai.com/api/ https://openai.com/api/, etc. (In general, search "[AI company] API".) From those B2B landing pages, you can usually click through to pages with details about each of their models. Here's the model page corresponding to this news announcement, for example: https://www.anthropic.com/claude/opus https://www.anthropic.com/claude/opus (Also, note how these B2B pages are on the AI companies' own corporate domains; whereas their B2C products have their own dedicated domains. From their perspective, their B2C offerings are essentially treated as separate companies that happen to consume their APIs — a "reference use-case" — rather than as a part of what the B2B company sells.)
