ByteDance Launches Doubao-Seed-2.1-Pro at Volcano Engine FORCE Conference
ByteDance
ByteDance unveiled Doubao-Seed-2.1-Pro on June 23 at the Volcano Engine FORCE conference in Beijing — a production-level frontier LLM for coding, long-horizon agentic tasks, and multimodal understanding. Also released: Doubao-Seed-2.1-Turbo at half the price (6 yuan per million input / 30 yuan per million output tokens for Pro). ByteDance claims parity with GPT-5.5 on coding and agent benchmarks, topping OSWorld, MobileWorld, and MMMU-Pro. The Doubao family now exceeds 180 trillion daily token calls — up 10x year-over-year.
Why it matters
ByteDance is directly competing with frontier closed-source models at Chinese market pricing, using its Doubao consumer product as both a distribution channel and an internal evaluation harness. Reaching 180 trillion daily tokens signals that Seed models are running at hyperscale production, not just research scale.
