Overview and history

Seed-OSS is an official ByteDance Seed model family represented here through independently verified release, checkpoint, license, runtime and hardware evidence. ByteDance Seed-OSS is a dense 36B open family built for native 512K context, reasoning and agentic research. Current public releases are grouped by the General tracks so sibling sizes and specialist branches are not presented as false chronological generations.

FusionPointAI currently tracks 1 certified public Seed-OSS releases. The catalogue preserves release dates and evaluates Current, Recent, Previous and Legacy status within each model track rather than by database insertion order.

Architecture and model range

The verified public range spans 36B to 36B total parameters and context windows up to 524,288 tokens. Each release states whether it is dense or mixture-of-experts and records active parameters separately when the official source publishes them.

Deployment ecosystem

Choose a specific Seed-OSS release and certified checkpoint before sizing hardware. FusionPointAI rejects unknown runtime configurations, calculates resident memory from total model weights, then distinguishes globally compatible GPUs from currently rentable inventory.

Validate the exact checkpoint license, runtime version, precision kernel, context length, concurrency and multi-GPU topology. Active MoE parameters affect compute, but resident model memory continues to use total stored weights.

Common use cases

Long-context assistants
Agent research
Private inference

License overview

Licenses are certified per release, not inferred from the provider. Review the release page before commercial deployment because terms can differ between generations and variants.

Commercial-use status is a source-backed catalogue classification, not legal advice. Follow the linked official license and attribution requirements.

Frequently asked questions

Which Seed-OSS release is current?

Current releases are Seed-OSS 36B Instruct, evaluated within their respective tracks.

Can Seed-OSS be self-hosted?

Only releases with a verified official checkpoint and supported runtime configuration are presented as deployable.

Which GPU should run Seed-OSS?

GPU selection depends on the exact variant, checkpoint precision, context length and concurrency; use the release hardware recommendations rather than the family name alone.
