According to CoinMeta, DouBao 2.1 recently underwent its first major update in nearly three months, processing 1,000 real issue cases, with 83% meeting the merge criteria. This update included enhancements to agent, coding, and multimodal capabilities. Particularly in terms of coding, the model processed approximately 387,000 lines of historical issue code on the open-source game luanti. Multiple sub-agent processes ran continuously for nearly 36 hours, and ultimately 83% of the tasks met the merge standards. In addition, the new version of the model has enhanced visual understanding capabilities, allowing it to write code directly based on design drafts, sketches, and operation screenshots, as well as handle web 3D and game development tasks. Official case studies show that the model, after reading 280,000 lines of Java ERP code, was able to develop a functional mobile page solely using screenshots and sketches.
