On October 9, ByteDance's Doubao announced a two-part update to its Doubao Work product: the work-task mode gains a canvas feature that lets users lay out assets, plans and generated results on one infinite canvas for viewing, comparison and organization, then keep editing text, colors and layout after generation, with images, video and HTML auto-flowing into the same canvas from the "creative design" and "creative video" skills. The update also adds the new Seedream 5.0 Flash image model and puts Doubao 2.1 Lite (0921 build) into Doubao Work; the company says the model targets high-frequency office work such as Q&A, document writing, spreadsheets and slide creation with faster delivery and lower quota use, and claims leading multimodal understanding. Doubao 2.1 Lite sits alongside Doubao 2.1 Turbo and Doubao 2.1 Pro in the model picker, with adjustable reasoning effort.
