Seed-OSS is a series of open-source large language models developed by the ByteDance Seed team, designed for powerful long-context processing, reasoning, agent capabilities, and general-purpose abilities. Within this series, Seed-OSS-36B-Instruct is an instruction-tuned model with 36 billion parameters that natively supports an ultra-long context length, enabling it to process massive documents or complex codebases in a single pass. The model is specially optimized for reasoning, code generation, and agent tasks (such as tool use), while maintaining balanced and excellent general-purpose capabilities. A key feature of this model is the ‘Thinking Budget’ function, which allows users to flexibly adjust the reasoning length as needed, thereby effectively improving inference efficiency in practical applications...
