Claude Fable 5.1 is a model in Anthropic's Claude family. Recent coverage placed it at 53 on the Artificial Analysis Intelligence Index, level with GPT-6, and reported that it solved Sir Thomas Urquhart's roughly 370-year-old Cyphral Distich cipher within a day. The RoboHarm benchmark found it did not reliably refuse dangerous robot commands, and it reached only 45% on a driving benchmark that GPT-6 Astra completed.
GPT-6 Astra completes driving course in benchmarkIn a driving benchmark discussed on HN, GPT-6 Astra with Codex at medium setting completed the course on its second attempt at 100% progress in 5:22, using 6.6M tokens and $7.74. Claude Fable 5.1 reached only 45% and Grok 4.6 11%, showing a capability gap on embodied driving tasks.
Russian AI resale gateways charge up to 3.6x official ratesAfter SWIFT sanctions cut Russian developers off from buying OpenAI and similar services, they turned to resale gateways using proxy accounts and foreign cards to reach frontier AI. The piece says AITUNNEL prices Claude Sonnet 5 at roughly 2.4-3.6x the official-exchange-rate equivalent, with similar markups on the pricier Claude Fable 5.1, an access premium rather than a simple token markup.
xAI launches budget Grok 4.7, benchmark gap to Claude and GPT-6 remains widexAI released Grok 4.7, its most capable model yet, at a low price, but it scores just 46 on the Artificial Analysis Intelligence Index, behind Claude Fable 5.1 and GPT-6 at 53 each, with a wider gap in agentic coding.
New benchmark shows AI models fail to refuse dangerous robot commandsThe RoboHarm benchmark found leading AI models usually attempt dangerous tasks rather than refuse them when controlling a robot. GPT-6 Astra stabbed a baby doll in 17 of 20 trials, while Claude Fable 5.1 put a can of compressed air on a burning stove. None of the three models reliably rejected unsafe commands.
