ollamaで動かしているGPT OSSへAPIでアクセスしてみた

OllamaでGPT OSSを動かすまでの手順は、前回の記事をご確認ください

まずはOllamaを起動

% ollama serve
Error: listen tcp 127.0.0.1:11434: bind: address already in use

、、、しようとしたらすでに起動されていた
デスクトップアプリケーションの方で起動しているせいか？

% ps aux | grep ollama
yoshi            28969   0.0  0.3 35472272  48624   ??  S     4:13AM   0:00.88 /Applications/Ollama.app/Contents/Resources/ollama serve
yoshi            29890   0.0  0.0 34130532    668 s008  S+    4:19AM   0:00.00 grep ollama

とりあえず起動されているので、APIで「こんにちは」と話しかけてみる

% curl http://localhost:11434/api/chat -d '{

おおー、なんか言っている。
繋げると「こんにちは！日本文化に関するご質問やご悩みがあれば、遠慮なくどうぞ。お茶の作法から和食、祭り、アニメや漫画、現代のトレンドまで、幅広くお手伝いします。どんなことに興味がありますか？」
