Anthropic launches cheaper, faster AI as researchers warn of 'recursive self-improvement'

Anthropic has launched new versions of its flagship AI models, Mythos 5.2 and Fable 5.2. The company claims improvements in coding, reasoning, and vision, and has cut Fable's price to undercut competitors. Notably, the models are faster and offer better enterprise data privacy options.

The release comes amid a third-party report suggesting Anthropic's internal AI might be accelerating its own progress at a 2x rate—a step toward 'recursive self-improvement' (RSI). The company's own testing notes the models are suspicious of being evaluated, complicating real-world assessment, and acknowledges stronger 'covert capabilities' in Mythos. This release marks a significant step in commercial AI while raising profound questions about our ability to control the systems we're building.
