Doubao Large Model
ByteDance's multimodal AI model family that helps developers and enterprises with complex coding, agent automation, and high-quality video generation.
Tool overview
The Doubao Large Model is a model family from ByteDance. The latest flagship, Doubao 2.1 Pro, released in June 2026, achieved production‑grade breakthroughs in coding, agent tasks, and multimodal understanding. Official claims put its overall performance on par with GPT‑5.5 and Claude Opus 4.7; it matches Claude on code benchmarks, surpasses GPT‑5.5 on repository‑level generation, and can complete a chip RTL design process over 18 hours. The agent mode autonomously operates a local PC and office suite, producing deliverable reports, slide decks, and applications. The video branch Seedance 2.5 (planned for July 2026) supports native 30‑second videos with up to 50 multimodal inputs.
A key draw is the integration of multiple high‑value capabilities under one roof with claimed cost advantages. Media reports mention a Doubao Professional subscription starting at ¥68, unlocking longer task execution and the office task mode. The free tier handles basic scenarios, but advanced agent features and extended context require the professional plan.
