Seed 2.0

By ByteDance
Model family: Seed
The link you shared points to a Seed2.0 model card PDF hosted on ByteDance’s Lark/Bytedns static storage, but from this environment that file returns an HTTP error, so I cannot read or quote it. Outside of that private document and a few rumor-style mentions, no official open documentation of Seed 2.0’s capabilities seems to be available yet, so anything more specific would be guesswork.
New Multimodal Gen 3
Released: February 14, 2026

Overview

Seed 2.0 is described publicly only as a new ByteDance Seed language model for Doubao, but there is not yet any reliable, detailed public technical description of its architecture, context length, or training data that I can quote.
