ByteDance's Seed team quietly dropped SeedFold in late December 2025 — a revolutionary diffusion-based model for all-atom biomolecular structure prediction and de novo protein design. By dramatically scaling pair representation dimensions and introducing linear triangular attention variants, SeedFold achieves SOTA on FoldBench, outperforming AlphaFold3 on most protein tasks while enabling lightning-fast generative design via its companion SeedProteo model. This open-source release marks ByteDance's aggressive entry into AI-for-Science, challenging DeepMind's dominance in structural biology.

ByteDance's Seed Team officially released Seed1.8 on December 17, 2025 — a groundbreaking generalized real-world agent model that integrates core LLM and VLM strengths with multi-turn interaction, tool calling, code execution, and iterative decision-making. Designed as a unified agentic interface, it supports search, GUI navigation, and complex workflows without task-specific pipelines. Now available via the Doubao platform and Volcano Engine API, Seed1.8 pushes multimodal Agent capabilities into the global first tier, with early benchmarks showing superior performance in BrowserComp and agentic tasks.

ByteDance's Seed Team launched Depth Anything 3 (DA3) on November 14, 2025 — a groundbreaking visual spatial reconstruction model that fuses arbitrary images into consistent 3D geometry using a single plain transformer and depth-ray prediction. Open-sourced on GitHub with three model series (Giant for any-view, Metric for scale-aware, Nested for metric fusion), it crushes VGGT by 35.7% in pose accuracy and 23.6% in reconstruction, while matching Depth Anything 2's monocular detail. From robotics to VR, DA3's one-pass inference slashes complexity, powering Blender addons and Hugging Face demos — a minimalism masterstroke in 3D perception.
