On February 14, just three days before the Chinese Lunar New Year, Volcano Engine officially rolled out the Doubao Large Model 2.0. This model series encompasses three versatile Agent models—Pro, Lite, and Mini—alongside a Code model. All these models are designed to be flexibly tailored to a wide array of business scenarios. This launch signifies the first major generational leap since ByteDance introduced the Doubao Large Model family in May 2024. Doubao 2.0 achieves remarkable advancements in multimodal comprehension, the execution of complex instructions, and reasoning efficiency. The Pro version establishes a new industry benchmark in visual reasoning benchmark tests, whereas the Code version is specifically fine-tuned for programming tasks, yielding even superior outcomes when utilized in tandem with TRAE. Presently, Doubao 2.0 Pro is accessible through the Doubao App, as well as on desktop and web platforms. The Code version is seamlessly integrated into the AI programming product TRAE. Furthermore, Volcano Engine has initiated API services for the entire model lineup.
