Allie K. Miller tests Anthropic's Claude Fable 5.2 on complex tasks
Overview
Anthropic has released Claude Fable 5.2, according to Allie K. Miller, who tested it by prompting it to build a nationwide US water safety map.
The map draws on federal data from the EPA, USGS, NOAA, FEMA and the Census Bureau, rating 3,100 counties and more than 900 city areas on 17 measures.
Miller says she trusted Fable 5.2 more than any model she has tested on five complex tasks, and that finding a needle in a haystack is no longer a problem with it. She also reports that the model made obvious errors in colors, units and slide text that secondary agents missed.
