Svmuu News: According to AI observer Andrew Curran, Anthropic has completed training a new, more powerful version of the Mythos model. However, it is currently unclear whether the model will be named Mythos 5.1 or Mythos 6, and it cannot be ruled out that it will be used solely for internal R&D to accelerate the development of subsequent models. Additionally, with the “claude-sonnet-5” model identifier appearing on Anthropic’s partner service platform, the developer community widely speculates that Claude Sonnet 5 may be officially released this week.
