# MolmoE 1B


Molmo is a family of open vision-language models developed by the Allen Institute for AI. 
Molmo models are trained on PixMo, a dataset of 1 million, highly-curated image-text pairs. 
It has state-of-the-art performance among multimodal models with a similar size while being fully open-source. 
You can find all models in the Molmo family [here](https://huggingface.co/collections/allenai/molmo-66f379e6fe3b8ef090a8ca19).
**Learn more** about the Molmo family [in our announcement blog post](https://molmo.allenai.org/blog).

MolmoE-1B is a multimodal Mixture-of-Experts LLM with 1.5B active and 7.2B total parameters based on [OLMoE-1B-7B-0924](https://huggingface.co/allenai/OLMoE-1B-7B-0924). 
It nearly matches the performance of GPT-4V on both academic benchmarks and human evaluation, and achieves state-of-the-art performance among similarly-sized open multimodal models.

This checkpoint is a **preview** of the Molmo release. All artifacts used in creating Molmo (PixMo dataset, training code, evaluations, intermediate checkpoints) will be made available at a later date, furthering our commitment to open-source AI development and reproducibility.

**[Sign up here](https://docs.google.com/forms/d/e/1FAIpQLSdML1MhNNBDsCHpgWG65Oydg2SjZzVasyqlP08nBrWjZp_c7A/viewform)** to be the first to know when artifacts are released.

## Quick Start

To run MolmoE, first install dependencies:

```bash
# uninstall all tensorflow packages
pip list --format=freeze | grep '^tensorflow' | cut -d= -f1 | xargs -n1 pip uninstall -y

# install CPU-only version of tensorflow; used for image preprocessing
pip install einops tensorflow-cpu torchvision
```

Then, follow these steps:

```python
from transformers import AutoModelForCausalLM, AutoProcessor, GenerationConfig
from PIL import Image
import requests

# load the processor
processor = AutoProcessor.from_pretrained(
    'allenai/MolmoE-1B-0924',
    trust_remote_code=True,
    torch_dtype='auto',
    device_map='auto'
)

# load the model
model = AutoModelForCausalLM.from_pretrained(
    'allenai/MolmoE-1B-0924',
    trust_remote_code=True,
    torch_dtype='auto',
    device_map='auto'
)

# process the image and text
inputs = processor.process(
    images=[Image.open(requests.get("https://picsum.photos/id/237/536/354", stream=True).raw)],
    text="Describe this image."
)

# move inputs to the correct device and make a batch of size 1
inputs = {k: v.to(model.device).unsqueeze(0) for k, v in inputs.items()}

# generate output; maximum 200 new tokens; stop generation when <|endoftext|> is generated
output = model.generate_from_batch(
    inputs,
    GenerationConfig(max_new_tokens=200, stop_strings="<|endoftext|>"),
    tokenizer=processor.tokenizer
)

# only get generated tokens; decode them to text
generated_tokens = output[0,inputs['input_ids'].size(1):]
generated_text = processor.tokenizer.decode(generated_tokens, skip_special_tokens=True)

# print the generated text
print(generated_text)

## FAQs

### I'm getting an error a broadcast error when processing images!

Your image might not be in RGB format. You can convert it using the following code snippet:

```python
from PIL import Image

image = Image.open(...)

if image.mode != "RGB":
    image = image.convert("RGB")
```

### Molmo doesn't work great with transparent images!

We received reports that Molmo models might struggle with transparent images. 
For the time being, we recommend adding a white or dark background to your images before passing them to the model. The code snippet below shows how to do this using the Python Imaging Library (PIL):

```python

# Load the image
url = "..."
image = Image.open(requests.get(url, stream=True).raw)

# Convert the image to grayscale to calculate brightness
gray_image = image.convert('L')  # Convert to grayscale

# Calculate the average brightness
stat = ImageStat.Stat(gray_image)
average_brightness = stat.mean[0]  # Get the average value

# Define background color based on brightness (threshold can be adjusted)
bg_color = (0, 0, 0) if average_brightness > 127 else (255, 255, 255)

# Create a new image with the same size as the original, filled with the background color
new_image = Image.new('RGB', image.size, bg_color)

# Paste the original image on top of the background (use image as a mask if needed)
new_image.paste(image, (0, 0), image if image.mode == 'RGBA' else None)

# Now you can pass the new_image to Molmo
processor = AutoProcessor.from_pretrained(
    'allenai/Molmo-7B-D-0924',
    trust_remote_code=True,
    torch_dtype='auto',
    device_map='auto'
)
```
