Anthropic's newest model scored 1271 Elo on the 3D experience test, a 67-point lead over its own siblings, and costs 20% less than its predecessor Anthropic has a new leader on one of AI’s more visual leaderboards. Claude Fable 5.2 ranks first on the AA-3D benchmark from independent evaluator Artificial Analysis, with a score of 1271 Elo. The company’s closest competition on the board is, awkwardly, itself. The next two spots belong to other Claude models. Anthropic unveiled Fable 5.2 on November 9, 2026. It is pitched as a model built for complex technical and agentic tasks, meaning work where the AI carries out multi-step jobs rather than answering one question at a time. The scoreboard AA-3D measures how well AI models build 3D experiences. The benchmark runs models through 55 tasks spanning several domains, including games and natural phenomena. Scores use Elo, the rating system borrowed from chess. A higher number means a model performs better relative to the others in the pool.
