Doubao-Seed-2.0 Pro

Abstract

Large Language Models (LLMs) now play a central role in modern digital infrastructure. Usage has grown dramatically across both professional and personal contexts [11]. The Seed team has developed a comprehensive model family that includes general-purpose LLMs, multimodal models, open-source releases, code-specialized models, diffusion-based language modeling, formal theorem proving, and generative media systems: Seed1.6/1.8, Seed1.5-VL, Seed-OSS, Seed-Coder, Seed Diffusion, and Seed-Prover. These models currently power a largescale product ecosystem serving hundreds of millions of daily active users across applications. Meanwhile, the field is moving toward an agentic paradigm where LLMs tackle scientific research, complex software development, autonomous documentation learning, and multi-step real-world workflows. This shift motivatesSeed2.0 Series (Pro / Lite / Mini), which is designed to deliver optimal user experience in large-scale production environments.
