arc

DiARC is a method that improves the reasoning ability of large language models on ARC-like tasks by constructing preference pairs from positive and negative samples, outperforming baselines across multiple benchmarks.

This IETF draft recommends reclassifying the ARC (Authenticated Received Chain) protocol as historic, concluding its experiment and pointing to DKIM2 as a successor.

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.
