BByteDance: Seed 2.1 Turbo API
seed-2.1-turbo
Seed 2.1 Turbo API is the lower-priced ByteDance option for text and image analysis within a 256K context. It emphasizes lower rates than Seed 2.1 Pro rather than a claimed benchmark lead. [1]
Seed 2.1 Turbo API is not present in the current LLM2014 logic table, so APINEED assigns no rank. Teams should compare its real latency and quality directly with Seed 2.1 Pro. [1][2]
