Model Card
Seed 2.0 Mini is ByteDance's most lightweight and inference-efficient model in the Seed 2.0 family, released in February 2026 and optimized for low-latency, high-concurrency, and cost-sensitive applications. It features a 256K context window, multimodal capabilities (text, image, video), and a unique 4-level reasoning effort system. Despite being the smallest variant, it delivers strong benchmark scores (AIME 2025: 87.0, SWE-Bench: 67.9) at an extremely competitive price of $0.1/M input tokens.

Seed 2.1 Turbo
Seed 2.1 Turbo is ByteDance's faster, lower-cost variant of the Seed 2.1 model family, released alongside Seed 2.1 Pro at its Volcano Engine FORCE conference in June 2026. It carries the same feature set as Pro, including coding engineering across full project cycles, long-chain agent workflows with multi-step tool use, and multimodal understanding of text, image, and video. ByteDance says the Seed 2.1 series matches GPT-5.5 on these three capability pillars, though that claim is vendor-reported and has not been independently verified. No Turbo-specific benchmark scores have been published separately from Pro. Turbo is priced at about half of Seed 2.1 Pro per token, which suits enterprise teams running high volumes of API calls, such as agent pipelines and document or image processing, where cost and latency matter more than peak capability.
ChatSeed 2.0 Lite
Seed 2.0 Lite is ByteDance's mid-tier general-purpose LLM that balances strong performance with cost efficiency, scoring 93 on AIME 2025 and 2233 on Codeforces while supporting text, image, and video understanding plus tool-calling capabilities. It serves as the default production-grade model in the Seed 2.0 family, handling roughly 95% of enterprise workloads at about half the cost of the flagship Pro variant. It supports a 256K context window and is positioned as a high-performance alternative for tasks like code review, document processing, information synthesis, and agent-based workflows.
