Claude Fable 5 Max Sets WeirdML High at 91.9%
Claude Fable 5 max scored 91.9% on WeirdML, setting a new best result on the benchmark, according to results posted Saturday by researcher H Tihle.
The posted breakdown said a task by task state of the art composite would be 93.5%, indicating the model stayed within a few percentage points of the best score on each run. Claude Fable 5 max matched the top score on 7 of 17 tasks, and its weakest run was 7 percentage points behind the best result on that task. The test used two runs per task rather than the usual five, a setup the post said both highlights the model’s consistency and can make it easier to avoid one or two bad runs.
