@scaling01 Says OpenAI Will Out-Accelerate Anthropic

@scaling01, who runs the LisanBench LLM reasoning benchmark, posted after the Mythos Preview and GPT-5.5 launches. The author stated that the scenario of OpenAI being ahead by 1-3 months by end of year is more likely after this launch. @scaling01 also wrote that it is quite likely now that OpenAI will out-accelerate Anthropic. The post adds that Anthropic has a better model internally, but suggests the difference is not that much bigger.
