lmsys/gpt-oss-20b-bf16 is an open-weights language model for text generation published by lmsys, added to Hugging Bay Sep 21, 2026. Model from Hugging Face for llm: lmsys/gpt-oss-20b-bf16 · unknown

Q: How big is it?

lmsys/gpt-oss-20b-bf16 has 20B parameters. Hosted here: 12 files, 22.7 GB. Full repo upstream: 22.7 GB. The recommended download, a 5-file weight set, is 22.7 GB.

Q: What can I download here?

Hosted here: 12 files, 22.7 GB. Full repo upstream: 22.7 GB.

Q: File pattern scans

Automated file-pattern scans flagged nothing; not a safety guarantee. 12 hosted files carry a published SHA-256 you can re-hash. The machine-readable verdict is at /api/artifacts/hf-model-lmsys-gpt-oss-20b-bf16/safety on Hugging Bay.

Q: Will lmsys/gpt-oss-20b-bf16 run on my computer?

We can’t check the fit; we don’t know your machine. We don’t have your machine’s specs, so no check ran and no verdict is shown. Answer two quick questions and we’ll estimate, from the memory you tell us, whether it fits your machine. Or skip it; you can still download; fit isn’t checked.

Quick answer: compatibility and sources

Can I run gpt-oss-20b-bf16 on my computer?

It depends on your memory, processor, file format and runtime. A download is not confirmed by the current file evidence; inspect the file record before trying it. A file-size fit is an estimate, not a successful run or speed promise. Read the license before use.

gpt-oss-20b-bf16 is an open-weights language model for text generation. Model weights are learned parameters; a runtime loads them. A hosted file is an individual file Hugging Bay can serve. SHA-256 identifies exact file bytes. The availability date above applies to this file record, not the upstream metadata update date.

As of the recorded file availability check on 2026-11-15.

Exact file evidence · Machine-readable source facts · Run evidence and any recorded receipts. A checksum fingerprints only the named file bytes; it does not prove safety, quality, a complete multi-file selection or a successful run.

Key facts

Catalog record: Summarizes upstream metadata; it is not itself a download or run receipt.
File evidence: Lists exact filenames, availability and any recorded SHA-256 for individual files.
Run evidence: Reports measured results only when a receipt exists for named file bytes and a setup; otherwise unmeasured.
Checksum scope: SHA-256 fingerprints one file’s bytes; it does not prove safety, quality or a multi-file bundle.

Evidence you can inspect (plain text)

This page’s quick answer names the file record for hf-model-lmsys-gpt-oss-20b-bf16.
Open /artifact/hf-model-lmsys-gpt-oss-20b-bf16/files for exact filenames, availability and any recorded SHA-256 for this model.
Open /evidence/artifacts/hf-model-lmsys-gpt-oss-20b-bf16 for run-readiness evidence tied to that record; absent receipts stay unmeasured.
Open /api/artifacts/hf-model-lmsys-gpt-oss-20b-bf16/card.md for machine-readable source facts (not a runtime test).
A matching checksum on this page fingerprints only the named bytes shown in file evidence.

Unmeasured states are stated explicitly; this page does not invent run scores or compatibility guarantees.

Which date applies to which fact

File availability check: 2026-11-15
Committed page-copy sources: 2026-10-21
Upstream model metadata: Dates on artifact records when shown; not implied by page-copy revision
Run receipts: Only on /evidence pages when recorded; otherwise unmeasured

Page-copy revision (Updated line above) identifies committed text sources, not upstream model edits or test outcomes.
