Doubao Seed 2.0 Mini — smallest Seed 2.0 variant for high-QPS edge use cases.
Doubao-Seed-2.0-Mini (also branded Dola-Seed 2.0 Mini internationally) is the smallest and most cost-efficient member of ByteDance's Seed 2.0 family, released February 14, 2026. It is a heavily distilled variant of the Seed 2.0 Pro backbone, engineered for high-throughput batch workloads, edge deployment, and cost-sensitive pipelines where price per token matters more than frontier reasoning depth.
For TheRouter operators, Seed 2.0 Mini occupies the high-QPS / low-margin tier alongside models like OpenAI GPT-4o-mini and Google Gemini 2.0 Flash Lite. It inherits the Seed 2.0 multimodal training (text + image) and tool-calling capability, but trades off context window and reasoning depth to achieve the lowest price point in the family. TheRouter YAML lists 131072-token context and text-only modality, making it suitable for short-to-medium document classification, content moderation, summarization, and lightweight agent loops.

Mini targets high-throughput batch and edge use cases at the lowest price point in the lineup.
Mini is the most aggressively distilled variant, optimized for maximum tokens per dollar and lowest latency at the expense of reasoning depth and context capacity. Lite sits between Mini and Pro — it retains the full 256K context and stronger agentic performance while still being significantly cheaper than Pro.
The Seed 2.0 family was trained with multimodal data. TheRouter's YAML entry for doubao-seed-2-0-mini currently lists text-only modality; operators should verify the exact supported input_modalities via the live model metadata before routing vision workloads.
