Doubao Seed Evolving is a rolling model from ByteDance, first released in June 2026 and updated at least once per week under a single stable model ID. ByteDance positions it for agent and coding scenarios. A July 2026 update raised its context window to 1M tokens.
Official documentation lists the same capability set as Doubao Seed 2.1 Pro: deep thinking, text generation, multimodal understanding, GUI task handling, tool calling and structured output. Because the model changes weekly, capability claims and pricing should be re-verified frequently. API pricing is 6.00 CNY input / 30.00 CNY output per 1M tokens, cache hits at 1.20 (as of 2026-09-20).
