+# OmChat: A Family of Powerful Native Multimodal Language Models
+We are thrilled to announce the release of OmChat Beta 2.0, a research version of our models from Om AI. This release includes the Qwen2 7B LLM-base and the InterVIT6B vision tower-based model, combining to form the OmChat Beta 13B model. These models are now available as open-source for researchers in the multimodal field, aimed at advancing meaningful research and contributing to the AI ecosystem's progress.
+
+In the near future, we plan to release OmChat Beta 2.1, which will include support for long context as detailed in the OmChat paper, as well as a lighter version of the model. We will continue to update our latest versions for research purposes. For performance evaluation, we have tested our models using the OpenCompass benchmarks.
+
+## Updates
+* 08/10/2024: The OmChat open-source project has been unveiled. 🎉
+* 07/06/2024: [The OmChat research paper has been published.](https://arxiv.org/abs/2407.04923)

+
+### An Example with Huggingface transformers
+Download huggingface model
+```bash
+git lfs install
+git clone https://huggingface.co/omlab/omchat-v2.0-13B-single-beta_hf
+```
+
+```python
+from transformers import AutoModel, AutoProcessor, AutoTokenizer
+from PIL import Image
+import requests
+import torch
+from transformers import TextStreamer
+
+model = AutoModel.from_pretrained("/omlab/omchat-v2.0-13B-single-beta_hf",trust_remote_code=True, torch_dtype=torch.float16).cuda().eval()
+processor = AutoProcessor.from_pretrained("/omlab/omchat-v2.0-13B-single-beta_hf", trust_remote_code=True)
+
+url = "https://www.ilankelman.org/stopsigns/australia.jpg"
+image = Image.open(requests.get(url, stream=True).raw)
+prompt ="What's the content of the image?"
+inputs = processor(text=prompt, images=image, return_tensors="pt").to("cuda")
+
+with torch.inference_mode():
+    output_ids = model.generate(**inputs, max_new_tokens=1024, do_sample=False, eos_token_id=model.generation_config.eos_token_id,  pad_token_id=processor.tokenizer.pad_token_id)
+
+outputs = processor.tokenizer.decode(output_ids[0, inputs.input_ids.shape[1] :]).strip()
+print (outputs)
+# The image features a stop sign in front of a Chinese archway, with a black car driving past. The stop sign is located on the left side of the scene, while the car is on the right side. There are also two statues of lions on either side of the archway, adding to the cultural ambiance of the scene.<|im_end|>

+### Available HF Models from Om AI
+- [omchat-v2.0-13B-single-beta_hf](https://huggingface.co/omlab/omchat-v2.0-13B-single-beta_hf) Currently, it supports only single images, but we will soon release models with multi-image and video support.
