Anthropic released FAble 5.1 and Mythos 5.1 and they continue to get better at agentic coding and scientific research.
Fable 5.1 will cost an estimated 25% less than Fable 5 for typical workloads, wherever usage is billed by token. This is because we’re reducing our pricing on cache reads (where the model reads inputs that have already been processed and stored). For highly agentic work, the savings will often be much larger—up to approximately 45%.
Here is the link to the Anthropic description.
Mythos 5.1 developed full working exploits in 98% of trials, up from 88%. Anthropic says these are the strongest cyber capabilities of any model it has released.
52.6% on Terminal Bench Science, more than double Fable 5, and evaluated with production safeguards on, so it understates the real capability

LLMs are competing mightily on price now, with China subsidizing Deepseek like they subsidized EVs previously and everything else they eventually came to dominate. What does the race to the price bottom do to the AI companies’ bottom line, even given things like Jevon’s paradox? There’s going to be a winnowing and the frontier models may not win the price wars.
