## Suverenita a hosting

Tento model je v katal%C3%B3gu len pre referenciu. Zatia%C4%BE nie je hostovan%C3%BD na LLM EU a %C5%BEiadny koncov%C3%BD bod prvej strany ho tu neobsluhuje. Po%C5%BEiadavky na%C5%88 smeruj%C3%BA priamo k poskytovate%C4%BEovi, pod%C4%BEa jeho vlastn%C3%BDch podmienok.

## Zhrnutie

gpt-oss-20b je men%C5%A1%C3%AD z dvoch modelov uva%C5%BEovania s otvorenou v%C3%A1hou od OpenAI: celkovo 21 mili%C3%A1rd parametrov, 3,6 miliardy akt%C3%ADvnych, licencovan%C3%BD pod Apache-2.0 a dostato%C4%8Dne mal%C3%BD na spustenie v pribli%C5%BEne 16 GB pam%C3%A4te. Jeho konfigur%C3%A1cia deklaruje rovnak%C3%A9 kontextov%C3%A9 okno s 131 072 tokenmi ako model 120B. Zameriava sa na lok%C3%A1lne a latenciu citliv%C3%A9 nasadenia, nie na %C5%A1pi%C4%8Dkov%C3%BA kvalitu.

## %C4%8Casto kladen%C3%A9 ot%C3%A1zky

### 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?

gpt-oss-20b is recorded at 21B total, 3.6B active (safetensors total 20,914,757,184) (source: https://huggingface.co/openai/gpt-oss-20b), with a context window of 131072 tokens (source: https://huggingface.co/openai/gpt-oss-20b/blob/main/config.json).

### Ceny

Tento model je v katal%C3%B3gu len pre referenciu. Zatia%C4%BE nie je hostovan%C3%BD na LLM EU a %C5%BEiadny koncov%C3%BD bod prvej strany ho tu neobsluhuje. Po%C5%BEiadavky na%C5%88 smeruj%C3%BA priamo k poskytovate%C4%BEovi, pod%C4%BEa jeho vlastn%C3%BDch podmienok.

### Stav overenia

Ak pole nem%C3%A1 zdroj, karta ho zobraz%C3%AD ako neoveren%C3%A9, namiesto toho, aby ho vyplnila. Pr%C3%A1zdne pole je inform%C3%A1cia.

LLM EU Verified znamen%C3%A1 zdokumentovan%C3%A9, nie pr%C3%A1vne certifikovan%C3%A9. Nie je to pos%C3%BAdenie zhody pod%C4%BEa AI Act a LLM EU nie je org%C3%A1n E%C3%9A.

### Verzie a varianty

Pre tento model nie je nasaden%C3%BD %C5%BEiadny playground: neobsluhuje ho %C5%BEiadny koncov%C3%BD bod, tak%C5%BEe po%C5%BEiadavka by nemala kam %C3%ADs%C5%A5.

### Benchmarky
