Seed 2.0 Pro is ByteDance's flagship Seed 2.0 model, built for long-chain reasoning and robustness across complex real-world workflows. It posts frontier math results, scoring 98.3 on AIME 2025 and 97.3 on HMMT, and competes with leading models on STEM benchmarks. The model is strong on coding and agentic tasks, reaching 76.5 on SWE-Bench Verified and 87.8 on LiveCodeBench v6. Its multimodal capabilities rank near the top on the LMArena vision leaderboard, with solid performance in visual reasoning, spatial understanding, and video comprehension, and it scores 74.0 on FrontierSci-olympiad for science reasoning. With a 256k context window and multimodal understanding across text, image, and video, Seed 2.0 Pro supports function calling for tool-use agents and adjustable thinking modes. It is positioned for demanding use cases such as large-scale reasoning, multi-step agent orchestration, and long-context agentic workflows.
