With that pricing I can't imagine why anyone would use Claude Sonnet through the API when Gemini 2.5 Pro is both better and cheaper (especially at long-context understanding).

Claude is a good deal with the $20 subscription giving a fair amount of sonnet use with Code. It's also got a very distinct voice as far as LLMs go, and tends to produce cleaner/clearer writing in general. I wouldn't use the API in an application but the subscription feels like a pretty good deal.
