ByteDanceSeed OSS 36B Instruct
ByteDance's Seed OSS 36B Instruct is a chat model designed for powerful long-context, reasoning, and general capabilities, with a context window of 524,288 tokens. It is genuinely best at math-related tasks, as evidenced by its top 25% Math Index score of 84.7. Notably, the model adopts a causal language model architecture with features like RoPE, GQA attention, RMSNorm, and SwiGLU activation, and is optimized for international use cases with flexible control of thinking budget and enhanced reasoning capability.

Frequently asked questions about Seed OSS 36B Instruct
Answered from the entry's own fields: context, license, modalities, evidence, serving and the memory to self-host.
Seed OSS 36B Instruct advertises a context window of 524,288 tokens, with a maximum output of 4,096 tokens in a single response. The figure is the creator's published maximum; a given provider may serve less, and the gateway routes on what each provider actually serves.
Yes. Seed OSS 36B Instruct is an open-weight model released under the Apache 2.0 license, so the weights can be downloaded and self-hosted within that license's terms.
Seed OSS 36B Instruct accepts Text and produces Text. The capabilities card on this page lists which API features each deployment honours, such as function calling and structured output, with the source each was checked against.
Seed OSS 36B Instruct has published results from Artificial Analysis, shown by suite in the benchmarks card above exactly as the publisher reported them. Scores are not combined across suites, and a suite that has not measured Seed OSS 36B Instruct is shown as not available rather than estimated.
Not on the managed pool today; Seed OSS 36B Instruct is listed for reference and comparison. Connect your own provider key or endpoint that serves it and the gateway runs it on your account, with routing decisions recorded the same way.
About 36.1 GB at INT8 for the weights and a default context, from the catalog's 36.2B parameter count; FP16 needs roughly twice that, and long contexts or many concurrent requests add KV cache on top. The GPU section on this page lists cards that hold it, and the capacity planner sizes it for your context length and traffic.
