CompareGet Started

Doubao Seed 1.6 is ByteDance's latest-generation Doubao model, served through Volcengine, with enhanced reasoning and broadly improved capabilities over earlier Seed releases. Part of the Doubao Seed series, it pairs a long context window with reasoning, tool use (function calling), and prompt caching, so it can drive tool-using agents and long-document workflows while caching cuts the cost of repeated prompts across multi-turn sessions. Its low input price of $0.12/M tokens, with cache reads at $0.023/M, keeps high-volume workloads economical. Context: 256K tokens, output: 64K. Released 2025-10-15. Accessible via the OpenAI-compatible protocol through Ofox.
