Original GitHub issue: https://github.com/ollama/ollama/issues/2894

I have 12600K + 64GB RAM + RTX 4090. I use Ollama + OpenCHat.

For some reason Ollama won't use my RTX 4090. How can I show the program my graphics card?

messages = chat_histories[chat_id]
    options = {
        "num_ctx": 12768,
        "num_thread": 10,
        "num_predict": 300,
        "repeat_last_n": 100,
        "temperature": 0.75
    }
    response = ""

config.json
server.log
app.log
