Failed to get a valid response from Ollama (HTTP Status: 500)

Error message

llama runner process has terminated: error loading model: unable to locate cpu buffer

---

What it means

This usually happens when Ollama can't allocate enough memory to load the model. If you're running on CPU with limited RAM, it may not be able to create the necessary buffer for the model.

How to fix it

Try using a smaller model, such as:

• TinyLLaMA (638 MB)

• Gemma 3B:1b (815 MB)

These use less memory and typically work fine even on systems without a dedicated GPU.

Tip: Always save your work before trying a larger model. If it doesn’t load, no harm done — just try a lighter one.
