### Is gpt-oss-20b served on LLM EU?

It has no endpoint in the catalogue, so it is catalogue only %E2%80%94 not hosted on LLM EU yet, with no region and no retention to report. A card whose status is "listed" is a catalogue entry, not a running deployment.

### Under what licence is gpt-oss-20b released?

gpt-oss-20b is recorded under apache-2.0. The recorded licence text is https://www.apache.org/licenses/LICENSE-2.0. The weights are downloadable (open_weights is true). LLM EU republishes the licence id and the link and gives no legal advice; the licence text governs.

### How large is gpt-oss-20b, and what context window does it have?
