Anthropic on Thursday released a new AI model, and no, it's not Claude Mythos Preview. Claude Opus 4.7 is now generally available, meant to help developers and vibe coders with their hardest coding tasks.

Opus 4.7, like a well-trained dog, is supposedly better at following instructions. Anthropic wrote in its blog post that Opus 4.7 takes instructions "literally," where previous models skipped or loosely interpreted prompts. It has improvements to its file-based memory system, so it should be able to recall information from previous sessions and documents. And it can handle larger image files and analyze data from charts more easily. 

Anthropic also said the model is more "tasteful and creative" when creating interfaces, documents and slide decks. There are no details on exactly what Anthropic considers bad versus good taste.

Anthropic made waves earlier this month when it revealed it had created Claude Mythos Preview, its next-generation model, but the model was so good at finding security gaps that the company would be sharing it with tech and internet infrastructure companies -- like Cisco, CrowdStrike and Amazon Web Services -- so they could address the issues Mythos found. 

The idea is that if tech companies can improve their systems with the help of AI, they will be more resilient to cyberattacks by bad actors who can use publicly available AI models like everyone else.

While Opus 4.7 isn't the same as Mythos, Anthropic is testing some of its new cybersecurity protections in Opus 4.7. These safeguards, which "automatically detect and block requests that indicate prohibited or high-risk cybersecurity uses," are the watered-down version of what will be in "Mythos-class" models, the company's blog post said. But they're still important as cybersecurity becomes increasingly saturated with AI, both for defense and for attack.
