anthropic could potentially release: > fable 5.2 > opus 5.2 > sonnet 5.1/5.2 this month. possibly anthropic's answer to astra and the upcoming gpt-6 sol/luna launches. opus 5.2 is already looking really good from the tests so far. and if anthropic has finally fixed sonnet, that could become a really good everyday model.
