Seed-1.6-Thinking

Abstract

Seed1.6 is the latest general-purpose model series unveiled by the ByteDance Seed team. It incorporates multimodal capabilities, supporting adaptive deep thinking, multimodal understanding, GUI-based interaction, and deep reasoning with a 256K context window. Seed1.6 is now available through the open API of Volcano Engine. You can try it out via the links provided at the end of this article. In Seed1.6, we introduced Adaptive Chain-of-Thought (AdaCoT), a novel technique for initiating thinking processes adaptively based on question difficulty. This adaptive approach enables a better trade-off between model effectiveness and reasoning performance. Seed1.6 models demonstrated competitive performance across diverse benchmarks. They matched or even outperformed Seed1.5-VL in multiple visual tasks, while also achieving high scores in generalization tests such as college entrance exams in China and abroad.
