https://huggingface.co/CohereLabs/North-Micro-Vision-Instruct#installationInstallation

InstallPyTorchfor your platform first. North Micro Vision requires Transformers 5.16.0, together withacceleratefor automatic device placement and Pillow for image loading. Until Transformers 5.16.0 is released, install the runtime dependencies and Transformers from source:

uv pip install accelerate pillow
uv pip install "git+https://github.com/huggingface/transformers.git"

Once Transformers 5.16.0 is available on PyPI, install the released package with:

uv pip install accelerate pillow "transformers==5.16.0"

Flash Attention 2 is optional. On supported CUDA systems, install it with:

uv pip install flash-attn --no-build-isolation

If you do not useuv, replaceuv pipwithpipin the commands above.

The following example loads an image from a URL and asks the model to describe it. Prompts can interleave text with one or more images; for text-only prompts, omit the image entries.

import torch
from transformers import AutoModelForImageTextToText, AutoProcessor

model_id = "CohereLabs/North-Micro-Vision-Instruct"

processor = AutoProcessor.from_pretrained(
    model_id,
)
model = AutoModelForImageTextToText.from_pretrained(
    model_id,
    dtype="auto",
    device_map="auto",
)

# To enable Flash Attention 2, load the model with the following settings:
# model = AutoModelForImageTextToText.from_pretrained(
#     model_id,
#     dtype=torch.bfloat16,
#     attn_implementation="flash_attention_2",
#     device_map="auto",
# )

image_url = "https://cdn-uploads.huggingface.co/production/uploads/66d732effe6684fc16b12c28/Io_5OCmftsmH-n158ZtPs.png"
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": image_url},
            {"type": "text", "text": "What do you see?"},
        ],
    }
]

inputs = processor.apply_chat_template(
    messages,
    tokenize=True,
    add_generation_prompt=True,
    return_tensors="pt",
    return_dict=True,
).to(model.device)

outputs = model.generate(
    **inputs,
    max_new_tokens=128,
    do_sample=True,
    temperature=0.7,
    top_p=0.8,
    top_k=20,
)

generated_ids = [
    output_ids[len(input_ids) :]
    for input_ids, output_ids in zip(inputs.input_ids, outputs)
]
response = processor.batch_decode(
    generated_ids,
    skip_special_tokens=True,
    clean_up_tokenization_spaces=False,
)[0]
print(response)

The example uses the recommended Transformers sampling settings. For deterministic output, setdo\_sample=Falseand omittemperature,top\_p, andtop\_k.

https://huggingface.co/CohereLabs/North-Micro-Vision-Instruct#architectureArchitecture

North Micro Vision combines a custom-trained 400M-parameter native-resolution vision encoder with an in-house 2B-parameter language model North Micro LLM. The language model follows our Command A+ architecture, interleaving three sliding-window attention layers that use rotary positional embeddings with one global attention layer without positional embeddings. The vision encoder combines 2D RoPE with learned 1D positional embeddings to preserve spatial structure across native-resolution inputs.

The projector maps visual features into the language model’s embedding space. Following DeepStack, patch embeddings from multiple vision-encoder layers are injected into corresponding early LLM layers, giving the language model access to visual representations at different levels of abstraction.

High-level North Micro Vision architecture, consisting of a native-resolution vision encoder, a projector, and a language model.

Bounding boxes are returned as\[x1, y1, x2, y2\]on a normalized 0–1000 scale. Map them back to the original image by scaling each axis:

x1_px = x1 / 1000 * image_width
y1_px = y1 / 1000 * image_height
x2_px = x2 / 1000 * image_width
y2_px = y2 / 1000 * image_height

https://huggingface.co/CohereLabs/North-Micro-Vision-Instruct#vllmvLLM

Public vLLM support is coming soon. Until it is available, use Transformers as shown above. The recommended vLLM settings will be:

temperature = 0.7
top_p = 0.8
top_k = 20
min_p = 0.0
presence_penalty = 1.5
repetition_penalty = 1.0

https://huggingface.co/CohereLabs/North-Micro-Vision-Instruct#intended-useIntended Use

North Micro Vision Instruct is intended for research and development use cases such as:

• Prototyping and task-specific fine-tuning.
• General visual question answering and image captioning.
• Multilingual and multi-image understanding.
• Visual grounding and spatial understanding.
• OCR, chart and document understanding, and structured information extraction.

https://huggingface.co/CohereLabs/North-Micro-Vision-Instruct#limitationsLimitations

• The model is intended as a compact foundation for customization rather than a replacement for larger general-purpose chat assistants.
• It is not a reasoning model and has limited math and code-generation capabilities.
• Tool calling and agentic workflows are not supported.
• System prompts are not recommended because the model was not trained with them, although the chat template accepts thesystemrole.
• Multimodal training used an 8K-token context; longer contexts have not been validated.
• Native-resolution inputs can increase memory use and latency as image dimensions grow.
