Doubao Seed 1.6 Flash 250715
ByteDance Seed
Doubao Seed 1.6 Flash 250715 is the dated hosted snapshot of ByteDance Seed’s low-latency Seed1.6 Flash tier. Volcano Engine’s upgrade announcement says the Flash update improved code, reasoning, and math while retaining visual understanding and 10 ms time per output token; official service documentation classifies Seed1.6 Flash as a multimodal deep-thinking model that accepts text, images, and video, produces text, and offers controllable thinking. The provider advertises a rounded 256K context tier, so an exact context-window integer is not recorded.
