【#Tech24H】On June 23, Volcengine officially released the Doubao Large Model 2.1 series, including the flagship version Doubao-Seed-2.1-Pro and the lightweight version Doubao-Seed-2.1-Turbo, with APIs fully available on VolcanoArk starting the same day. Doubao 2.1 Pro achieves significant capability leaps in three core directions: coding, agent, and Vision-Language Modeling (VLM), outperforming Claude Opus 4.6 in multiple benchmark evaluations and officially crossing the threshold of production-grade quality transformation. Meanwhile, the video generation model Seedance 2.5 is scheduled for official release in early July, and the audio generation model 1.0 has simultaneously opened for invite-only testing, marking the Doubao ecosystem's comprehensive expansion from language understanding to multimodal content production. [ By Zhang Liyan ]
