What is Seed?
Seed is a collection of foundation AI models tool developed by ByteDance that enables developers and enterprises to integrate advanced AI capabilities into their applications. It provides large language models, vision-language models, and multimodal models for tasks like complex structure prediction, dexterous manipulation, and content generation. The program includes flagship models such as Seedance, an AI video generation model. Seedance 2.0, released in February 2026, is designed to convert text prompts, images, audio, and existing video clips into short video sequences, supporting resolutions up to 2K (2048x1080) and various aspect ratios including 16:9, 9:16, and 1:1. This iteration introduced a dual-branch diffusion transformer architecture and supports up to 12 simultaneous multimodal inputs, generating native synchronized audio alongside video. Recent updates in late April 2026 enabled omni-modal understanding in Seed2.0 Lite through audio input, unifying diverse audio and visual signal processing. In June 2026, ByteDance restructured the Seed architecture, centralizing robotics R&D under Zhou Chang to integrate robotics as a physical embodiment for large models. The Seed2.0 series also includes general-purpose agent models: Pro, Lite, and Mini, with Seed 2.0 Mini released on February 26, 2026, offering upgraded multimodal understanding and strengthened LLM and Agent capabilities for real-world tasks.
