And the usage in a $200 plan is worth about one fifth as much on Fable 5.2 as on Opus 5.5. 4/ On 30 ordinary coding tasks, two private tests found a tie with Opus 5.5. Fable cost almost twice as much per solved task. The gap shows only on big, hard jobs. 5/ Sources: game footage and cost estimates @MatthewBerman, plan math @theo, bug-hunt test @PawelHuryn, paper example @emollick, effort data @ArtificialAnlys. Not made or endorsed by Anthropic. Research: six Sonnet 5.5 agents. Script and animation: Fable 5.2. Using real user reports as the script is a great idea, way more honest than the usual hype reel. As a motion designer making launch videos, I'm curious: how much did you art-direct the visuals vs. let it run?
