ARC-AGI-3 UPDATE

Summary from the TLDR AI newsletter

ARC-AGI-3 is an Interactive Reasoning Benchmark designed to measure an AI Agent's ability to generalize in novel, unseen environments. Opus 4.6 demonstrates better reasoning and use of memory than Gemini 3.1 Pro and solves more levels. Current models may be able to solve ARC-AGI-3 given access to a harness with a simple memory. Memory scaffolds are likely enough for pseudo-continual learning to push us to some self-improvement or research-agent threshold within the next 2 years.
