Code snippet:

python
from mlx_lm import load, generate
model, tokenizer = load("mlx-community/IQuest-Coder-V1-40B-Instruct-4bit")
Issue Description: The model downloads successfully (21.4GB), but mlx_lm fails to load it because the model architecture type "iquestcoder" is not recognized. The library is looking for a module at mlx_lm.models.iquestcoder which doesn't exist.

Environment:

Python 3.12

pip show mlx-lm
Name: mlx-lm
Version: 0.30.0

Required-by:

Model: mlx-community/IQuest-Coder-V1-40B-Instruct-4bit
Question: Is this model architecture supported by the current version of mlx_lm? Do I need to upgrade the library or use a different approach to load this model?

This may take a few minutes on first run as it downloads the model.
