No, Anthropic's New Claude Opus 4.7 Model Is Not Mythos Preview
Anthropic says the model improves hard coding tasks, vision and memory while adding safeguards against high-risk cybersecurity use, and it trails Mythos Preview.
- On Thursday, Anthropic released Claude Opus 4.7, a flagship AI model featuring major improvements to advanced software engineering, sharper vision capabilities, and self-verification for complex tasks.
- The release follows weeks of user complaints that Opus 4.6 had been deliberately scaled back, what users called 'nerfed.' Anthropic denied that capability reductions were made to redirect compute resources toward other projects.
- Benchmarks show Opus 4.7 outperforms GPT-5 and Google Gemini 3.1 Pro across multiple tasks, though an updated tokenizer may increase token usage by roughly 1.0 to 1.35 times depending on content type.
- While Anthropic describes Opus 4.7 as 'broadly less capable' than its restricted Claude Mythos Preview, the advanced model remains unavailable to the public due to safety concerns and stays limited to select partners.
- Future deployment of Mythos-class models depends on real-world testing of safeguards that automatically detect and block high-risk cybersecurity requests, while developers can now access an 'xhigh' effort level for complex reasoning tasks.
