gpt-ossのモデルを動かす

$ ollama run gpt-oss:20b
>>> こんにちは
Thinking...
The user says "こんにちは". That's Japanese greeting "Hello". Should respond politely, maybe in Japanese. Simple greeting. Probably respond with "こんにちは！今日はどうされましたか？" or
something. The user might just say hello. So respond.
...done thinking.

こんにちは！今日はどんなご用件でしょうか？何かお手伝いできることがあれば教えてくださいね。

gpt-oss:latest は、サイズが13GBなので、20Bのgpt-ossが入ってることがわかる。120Bではない。120Bは、65GBある。
