Step launches Step5Preview, a 600B sparse MoE model optimized for real-world Agentic tasks. Activating only 27B parameters, it supports 1M token context and multimodal inputs. Scoring top-three globally, it costs one-eighth of Claude Opus5 while matching performance in coding, long-horizon reasoning, and finance. Key benchmarks include surpassing Opus5 in GPU kernel optimization and demonstrating robust multi-step agent workflows. Full open-source weights release October 15, positioning Step5Preview as a high-efficiency flagship for daily agent use.

GPT-6Astra and three researchers solved a 2017 math problem on FrontierMath proving the core always exists in approval-based committee elections. The AI invented a new voting rule using harmonic entropy and provided a polynomial-time algorithm. This marks the first time AI solved a major breakthrough math problem, shifting large models from problem-solving tools to collaborative pattern-discoverers. Epoch AI now recognizes Human+AI joint achievements, signaling a rewrite of scientific research methods where humans act as prompt engineers guiding AI-driven discovery.
