By ByteDance
Model family: Seed
Seed1.5, also known as Doubao-1.5-pro, is a sparse MoE foundation model trained end-to-end for both quality and serving cost. It reaches leading scores on public benchmarks in knowledge, code generation, reasoning and Chinese, rivaling much larger dense LLMs, and serves as the base for Doubao products and the Seed1.5-VL multimodal stack.

Seed by ByteDance — v1.8Stronger emphasis on real-world complexity evaluation via a 4-part framework (Science Discovery, Vibe Coding, Context Learning, Real-World Tasks) instead of Seed1.8’s broader benchmark grouping. Deeper GUI-agent focus with explicit end-to-end evaluations in heavy “real app” environments like FreeCAD (CAD) and CapCut (video editing), which are not used as named GUI testbeds in Seed1.8. More direct focus on reducing visual hallucinations and improving structured extraction from screenshots, charts, and scanned documents compared to Seed1.8’s more general multimodal capability framing. Tool orchestration is treated as a more central capability axis, highlighting orchestration benchmarks (for example MCP-Mark) beyond the tool-use framing in Seed1.8. The write-up shifts from “generalized real-world agency” toward “intelligence frontier for real-world complexity,” putting more weight on long-horizon, high-value workflows (research, coding projects, context learning) as the organizing target.
