Commonwealth Fusion Systems has published five peer-reviewed papers detailing the physics basis for its ARC fusion power plant, which is expected to produce 400 MW of electricity. The company's approach uses high-temperature superconductors to build a smaller, faster reactor.

GraphARC is a new benchmark for abstract reasoning on graph-structured data, extending the ARC paradigm to graphs. Evaluations of state-of-the-art language models reveal a comprehension-execution gap and performance degradation on larger instances, highlighting scaling challenges.
