Anthropic to release Mythos-class models to the public
Anthropic plans to eventually release its Mythos-class AI models to the public once adequate safety measures are established. Currently, these models are only accessible to select partners due to concerns about potential misuse. The company has found over 6,000 critical vulnerabilities in open-source projects using Mythos, highlighting the need for careful management of AI-generated bug reports.
- ▪Anthropic has developed a model called Mythos that excels at finding security vulnerabilities in programming code.
- ▪The company is currently offering access to Mythos through a program called Project Glasswing, which is limited to select entities.
- ▪Mythos has identified over 6,200 high-or-critical-severity vulnerabilities in more than 1,000 open-source projects.
