ByteDance Elevates 'Doubao' to 2.0 — A Productised, Multi‑variant Large Model Push with Bold Benchmark Claims

ByteDance has launched Doubao 2.0, a family of production‑oriented large models (Pro, Lite, Mini, and a Code variant) focused on efficient inference, multimodal ability and long‑chain task execution. The company claims strong benchmark performance versus rivals but faces scrutiny over IP and international review requests, highlighting the tension between rapid commercialisation and the need for independent validation and regulatory compliance.
