What is the issue?

If I download the safetensor model from Huggingface and I try to convert it with Ollama 11.2 and I set the quantization MXFP4 Ollama gets error because it doesn't support it.

How can I fix this bug?

After the update from 11.0 to 11.2 I've got the error: Error: unknown architecture

Ollama does not use llama.cpp. We've directly worked with OpenAI to implement the model for accuracy, and we've benchmarked against the reference implementations.

The best way is to download the model directly via Ollama's app or via CLI

Sorry about this!
