gpt-ossのモデルを動かす

$ ollama run gpt-oss
>>> 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。

>>> Send a message (/? for help)

mac-intelのメモリ32GB程度だと、レスポンスに1分以上かかる。

モデルリスト表示

$ ollama list
NAME              ID              SIZE     MODIFIED
gpt-oss:latest    aa4295ac10c3    13 GB    About an hour ago

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、70GB以上あるはず。

モデルのインストールパス

~/.ollama/models/manifests/registry.ollama.ai/library/<モデル名>/<バージョン>/

インストールに必要なメモリ

最低16GB程度は必要。
