Anthropic is releasing two new models, Claude Fable 5.2 and Mythos 5.2, according to a report from The Decoder. The company describes them as its most powerful models to date. One version will be freely available. The other will be reserved for verified organizations.
Anthropic says the models can solve open physics problems and show stronger cybersecurity capabilities. The company also says they can design functioning operating systems. According to the company, the models write more than 90 percent of the changes merged into Anthropic's core code.
Anthropic says it has deliberately limited any capabilities that would let the AI speed up its own development.
The report's headline links the release to Anthropic's position just before its IPO. The source material does not provide further detail on that point.
