Voice of the community
sample 1,580“Seed 2.0 Pro is competitive with GPT-5.2 and Gemini 3 Pro on most benchmarks at ~3.7-5.9x lower cost. For most production workloads, the 10x cost savings outweigh the gaps.”
“ByteDance ships agentic capabilities into production: deep research, coding assistants via TRAE IDE, and autonomous search agents in the Doubao app. Not just benchmarks.”
“Seed 2.0 Pro can process hour-long videos and answer questions about content, motion, and temporal relationships. VideoMME 89.5 is genuinely impressive.”
