The latest releases follow a report by third-party assessment group METR suggesting Anthropic could be approaching recursive self-improvement (RSI). At this stage, AI models can independently contribute to their own training and development.
The report found that Anthropic's internal models were accelerating the company's AI progress by roughly 2x, although several uncertainties remain.
Anthropic also acknowledged difficulties in evaluating increasingly capable models. The company said Mythos 5.2 and Fable 5.2 appear more suspicious of being tested than previous models, making it harder to assess how they might behave in real-world situations.
