Anthropic Launches Claude Opus 5.5 With Fable-Level Performance at a Lower Price

Anthropic today launched Claude Opus 5.5 , which it says is the first model in a new 5.5 model family. Opus 5.5 performs at the level of Claude Fable 5.1 on most work, but costs 40 percent less to run than Opus 5. According to Anthropic, Opus 5.5 is a "major step up" from Opus 5 with improvements in performance and safety. Opus 5.5 is comparable to Mythos 5.1 in biology and cybersecurity, so Anthropic is launching it with safeguards similar to those on Fable 5.1. Opus 5.5 also generates output over 30 percent faster than Opus 5. On benchmarks shared by Anthropic, Opus 5.5 surpassed Fable 5.1 on agentic coding, knowledge work, computer use, visual chart recognition, and multidisciplinary reasoning. Anthropic says the model communicates more naturally than prior models, putting important information at the front of a response so it's easier to understand at a glance. It is less likely to use jargon or idiosyncratic phrases, and it follows the writing rules it's given. Claude Opus 5.5 is available on all platforms as of today. With the launch of Opus 5.5, Anthropic is raising the five-hour usage limits on Pro, Max, Team, and seat-based Enterprise plans. Subscribers have also received a rate limit reset that can be used anytime between now and October 22.

How would AI actually ‘kill all humans’? Here are the top five most likely scenarios | Toby Walsh

From a dangerous new bioweapon to total societal breakdown, is a ‘superintelligent’ AI capable of wiping out humanity? Earlier this month, artificial intelligence researcher Jacob Coxon resigned from Anthropic after just four months. In an announcement on X, he stated : “The people building AI earnestly believe that it could kill us all by the end of the decade.” A senior member of Anthropic’s staff, Evan Hubinger, actually agreed with Coxon, adding he personally thinks the chance of this happening in the next decade is more than 10% .
