ByteDance: Doubao-Seed-2.0-mini API
Doubao-Seed-2.0-Mini (v260215) is the ultra-high-speed, ultra-low-cost variant of the Doubao 2.0 foundation model family. Specifically engineered for extreme throughput and sub-second latency, it provides a "Flash" level experience for large-scale standardized tasks. Despite its compact size, it features the same 256k long-context support as its Pro/Lite counterparts and introduces "Four-Level Thinking Modes," allowing developers to deploy flexible reasoning even in a lightweight package. In 2026, it is the industry benchmark for high-frequency classification, real-time multilingual translation, and massive content moderation, offering intelligence comparable to the previous generation's larger models (e.g., v1.6) but at a fraction of the operational cost.
