Seed 2.0 Lite

Seed-2.0-Lite occupies the middle ground in ByteDance's Seed 2.0 model family, designed to serve as the workhorse for the majority of enterprise AI workloads. Rather than chasing peak benchmarks, the architecture balances output quality with response speed, making it practical for real-time applications where latency matters. It employs early fusion to natively process text, images, and video together within a single context window, and includes built-in tool-calling capabilities for orchestrating agentic workflows. This combination of multimodal understanding and agent functionality positions the model as a default choice for production deployments that need versatility without flagship pricing.

The model's training emphasizes mathematical reasoning and competitive-level coding skills, as evidenced by its AIME 2025 score of 93 and Codeforces rating of 2233. It demonstrates solid breadth across domains, with strong software engineering capability on benchmarks like SWE-Bench and broad knowledge understanding on MMLU-Pro. Handling roughly 95% of enterprise workloads at roughly half the cost of the Pro variant, Seed-2.0-Lite strikes a practical balance between capability and efficiency. With a 256K token context window and optimizations for high-frequency visual understanding, it excels at code review, document processing, information synthesis, and cost-sensitive deployments at scale.
