            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("usermma/Darwin-28B-REASON-mlx-2Bit")
model = AutoModelForMultimodalLM.from_pretrained("usermma/Darwin-28B-REASON-mlx-2Bit")
messages = [
    {

            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
inputs = processor.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

	# usermma/Darwin-28B-REASON-mlx-2Bit

	The Model [usermma/Darwin-28B-REASON-mlx-2Bit](https://huggingface.co/usermma/Darwin-28B-REASON-mlx-2Bit) was converted to MLX format from [FINAL-Bench/Darwin-28B-REASON](https://huggingface.co/FINAL-Bench/Darwin-28B-REASON) using mlx-lm version 0.31.2.

	## Use with mlx

	```bash
	pip install mlx-lm
	```

	```python
	from mlx_lm import load, generate

	model, tokenizer = load("usermma/Darwin-28B-REASON-mlx-2Bit")

	prompt="hello"

	if hasattr(tokenizer, "apply_chat_template") and tokenizer.chat_template is not None:
	messages = [{"role": "user", "content": prompt}]
	prompt = tokenizer.apply_chat_template(
	messages, tokenize=False, add_generation_prompt=True
	)

	response = generate(model, tokenizer, prompt=prompt, verbose=True)
	```
