Seed-OSS is a series of open-source large language models developed by ByteDance's Seed team, designed specifically for powerful long-context processing, reasoning, agents, and general capabilities. Among this series, Seed-OSS-36B-Instruct is an instruction-tuned model with 36 billion parameters that natively supports ultra-long context lengths, enabling it to process massive documents or complex codebases in a single pass. This model is specially optimized for reasoning, code generation, and agent tasks (such as tool usage), while maintaining balanced and excellent general capabilities. A notable feature of this model is the "Thinking Budget" functionality, which allows users to flexibly adjust the inference length as needed, thereby effectively improving inference efficiency in practical applications.

Which responds faster?

ByteDance-Seed/Seed-OSS-36B-Instruct: 2.8s time to first token measured on AIHubMix; see the live performance charts above for how each model behaves across the day.

How large is each context window?

ByteDance-Seed/Seed-OSS-36B-Instruct accepts 256,000 and kimi-k3 accepts 1,048,576 input tokens. Maximum output per request is 32,000 tokens on ByteDance-Seed/Seed-OSS-36B-Instruct and 1,048,576 tokens on kimi-k3.

Which one generates tokens faster?

ByteDance-Seed/Seed-OSS-36B-Instruct at 36.9 tok/s and kimi-k3 at 18.8 tok/s, measured as output throughput on AIHubMix — a separate metric from time to first token.

What inputs and capabilities does each model support?

ByteDance-Seed/Seed-OSS-36B-Instruct accepts text and image input and supports function calling and structured outputs; kimi-k3 accepts text, image and video input and supports thinking, function calling and structured outputs.

Can I call ByteDance-Seed/Seed-OSS-36B-Instruct and kimi-k3 with the same API key?

Yes. AIHubMix serves every model on this page behind one OpenAI-compatible endpoint, so switching between them is a one-line change to the model field — no second account, key or SDK.
