Anthropic has released Claude Opus 4.7, an ai model that is now available to try, with reported features including automated cybersecurity safeguards and benchmarks. The release's position in the market is unclear, with some outlets suggesting it leads in power among generally available models, while others mention rival models such as GPT-5.6 and Fable 5. Additionally, there are references to an unreleased model called Mythos, which may surpass Claude Opus 4.7 in some aspects.
