ByteDance / Doubao
ByteDance unveiled Doubao-Seed-2.1 Pro at the 2026 Volcano Engine FORCE conference on June 23, a flagship MoE LLM targeting enterprise coding, long-chain agent tasks, and vision-language understanding with million-token context windows. The model benchmarks competitively against GPT-5.5 and Gemini 3.1 Pro, priced at 6 yuan per million input tokens. ByteDance also previewed Seedance 2.5 (video generation) and Seedream 5.0 Pro (image generation) at the same event, completing a full-stack media AI suite.
Why it matters
Doubao now serves 180 trillion daily tokens — a 1,500× increase since launch — making this the most widely deployed Chinese AI product, with the 2.1 Pro release signaling ByteDance's push to monetize at enterprise scale.
