A new AI harness named "Schema" has been developed, which significantly improves performance on the ARC-AGI-3 benchmark. When used with Anthropic's Claude Opus 4.8 and Meta's Fable 5, Schema achieves a 99% score on the benchmark. A separate test using OpenAI's GPT-5.6 Sol model yielded a 95.35% score. Schema's improvements stem from its novel approach to processing observations, testing predictions, and executing plans, rather than altering the underlying model weights. AI
