Large multi-modal models for strong performance and efficient deployment
OmniLMM is a family of open-source large multimodal models (LMMs) adept at vision & language modeling. The model processes images and text inputs and delivers high-quality text outputs. We release two featured versions of OmniLMM that are targeted at strong performance and efficient deployment:
-
OmniLMM-12B: Leading performance among comparable-sized models on multiple benchmarks.
-
OmniLMM-3B: Frontier end device multi-modal conversation with promising performance.
OmniLMM-12B is the most capable version. The model is built based on EVA02-5B and Zephyr-7B-Ξ², connected with a perceiver resampler layer, and trained on multimodal data in a curriculum fashion. The model has three notable features:
-
π₯ Strong Performance.
OmniLMM-12B achieves leading performance among models with comparable sizes, surpassing established LMMs on multiple benchmarks (including MME, MMBench, SEED-Bench, etc). The model also endows rich multi-modal world knowledge.
-
π Trustworthy Behavior.
LMMs are known for suffering from hallucination, often generating text that is not factually grounded in images (e.g., faithfully describing non-existing objects in images). OmniLMM-12B is the first state-of-the-art open-source LMM aligned via multimodal RLHF for trustworthy behavior (using the recent RLHF-V technique). It ranks #1 among open-source models on MMHal-Bench, and outperforms GPT-4V on Object HalBench.
-
πΉ Real-time Multimodal Interaction.
We combine the OmniLMM-12B and GPT-3.5 (text-only) into a real-time multimodal interactive assistant. The assistant accepts video streams from the camera and speech streams from the microphone and emits speech output. While still primary, we find the model can replicate some of the fun cases shown in the Gemini Demo video, without any video edition.

We combine the OmniLMM-12B and GPT-3.5 (text-only) into a real-time multimodal interactive assistant. Video frames are described in text using OmniLMM-12B, and ChatGPT 3.5 (text-only) is employed to generate response according to the descriptions and user prompts. The demo video is a raw recording without edition.

OmniLMM-3B (i.e., MiniCPM-V) is an efficient version with promising performance for deployment. The model is built based on SigLip-400M and MiniCPM-2.4B, connected by a perceiver resampler. Notable features of OmniLMM-3B include:
-
β‘οΈ High Efficiency.
OmniLMM-3B can be efficiently deployed on most GPU cards and personal computers, and even on end devices such as mobile phones. In terms of visual encoding, we compress the image representations into 64 tokens via a perceiver resampler, which is significantly fewer than other LMMs based on MLP architecture (typically > 512 tokens). This allows OmniLMM-3B to operate with much less memory cost and higher speed during inference.
-
π₯ Promising Performance.
OmniLMM-3B achieves state-of-the-art performance on multiple benchmarks (including MMMU, MME, and MMbech, etc) among models with comparable sizes, surpassing existing LMMs built on Phi-2. It even achieves comparable or better performance than the 9.6B Qwen-VL-Chat.
-
π Bilingual Support.
OmniLMM-3B is the first end-deployable LMM supporting bilingual multimodal interaction in English and Chinese. This is achieved by generalizing multimodal capabilities across languages, a technique from the ICLR 2024 spotlight paper.

Please refer to the following codes to run OmniLMM.
from chat import OmniLMMChat, img2base64
chat_model = OmniLMMChat('openbmb/OmniLMM-12B') # or 'openbmb/MiniCPM-V'
im_64 = img2base64('./assets/worldmap_ck.jpg')
# First round chat
msgs = [{"role": "user", "content": "What is interesting about this image?"}]
inputs = {"image": im_64, "question": json.dumps(msgs)}
answer = chat_model.chat(inputs)
print(answer)
# Second round chat
# pass history context of multi-turn conversation
msgs.append({"role": "assistant", "content": answer})
msgs.append({"role": "user", "content": "Where is China in the image"})
inputs = {"image": im_64, "question": json.dumps(msgs)}
answer = chat_model.chat(inputs)
print(answer)We can obtain the following results:
"The interesting aspect of this image is the shape of the chicken nuggets on the pan. The nuggets are shaped like the continents of the world, which is an unusual and creative way to present the food. It adds a fun and playful element to the meal, making it more visually appealing and engaging."
"In the image, China is located on the right side of the pan. It is one of the nuggets shaped like the continents of the world, and its placement on the right side of the pan is consistent with its geographical location in the real world"
