UnverifiedOn the TasteVal benchmark, Opus 5.5 performed at roughly twice the human expert baseline, but task verification is fast and cheap, the human baseline does not include top-tier researchers, and the experiment scale was only 40 GPU hours and a single H100.71% similarUnverifiedThe 82 tasks in OS World were not run under identical conditions—half of the tasks retained the original baseline scores, and the invested resources and number of attempts also differed—so the 7-percentage-point improvement cannot be entirely attributed to memory.69% similarUnverifiedWhen the coding agent no longer generates its own tests, the task success rate improves, overall speed increases by approximately 6%, and costs decrease by approximately 9%.64% similarUnverifiedThe model has 512 experts per layer, but only 10 are activated per token, meaning the weights actually participating in computation are approximately 6B.63% similarUnverifiedIn a test of 100 tasks randomly sampled from an internal binary exploitation benchmark by Anthropic's red team, GLM-5.3 successfully developed a complete control flow hijack in 4% of trials.63% similar
