Doubao Seed 1.6
Seed1.6 is ByteDance’s multimodal foundation model with adaptive reasoning, offered under the Doubao name through Volcano Engine and internationally through BytePlus. Its 230B-parameter mixture-of-experts backbone activates 23B parameters and supports a 256K context. AdaCoT post-training lets callers choose automatic, full, or disabled thinking to balance latency and reasoning. Text and images can inform language answers, coding, document analysis, and interface understanding. Public weights are not offered. June 2025 availability is established by the official technical introduction and API catalog; the exact first public launch day is not asserted here.
