Have you ever wished you could converse with an AI that comprehends both spoken and visual data? The MultiModal-GPT paradigm combines language processing with visual understanding.
It offers the possibility of accurate and diversified human-computer interaction. MultiModal-GPT can provide descriptive captions, count individual items, and respond to general user questions.
But, how does it do that? And, what can you do with MultiModal-GPT?
Let’s take the story to the beginning and understand the possibilities ahead of us.
With the emergence of language models like GPT-4, natural language processing technologies are witnessing a revolution. Innovations like ChatGPT have already been incorporated into our lives.
And, they seem to keep on coming!
GPT-4 and Its Limitations
GPT-4 has shown amazing proficiency in multimodal conversations with people. Studies have made an effort to duplicate this performance, but because of the potentially high number of picture tokens, including models with precise visual information can be computationally expensive.
Existing models also do not include language instruction tuning in their study, which restricts their ability to participate in zero-shot multiturn image-text conversations.
Building Upon Flamingo Framework
A new model called MultiModal-GPT was developed to enable communication with people using both linguistic and visual cues.
The developers employed a program called the Flamingo framework, which was previously trained to comprehend both text and visuals, to make this feasible.
Flamingo needed some changes, though, as it was unable to have extended dialogues that included text and visuals.
The updated MultiModal-GPT model can gather data from pictures and mix it with language to comprehend and carry out human commands.
MultiModal-GPT is a type of AI model that can follow various human inquiries such as describing visuals, counting items, and answering questions. It understands and follows orders using a mix of visual and verbal data.
Researchers trained the model using both visual and language-only data to increase MultiModal-GPT’s capacity to converse with people. Additionally, it caused a noticeable improvement in the way its discourse was performed. It also resulted in a noticeable improvement in its conversation performance.
They discovered that having high-quality training data is critical for good conversation performance, because a small dataset with short responses may enable the model to create shorter responses to any command.
What Can You Do With MultiModal-GPT?
Engaging in Conversations
Like the language models that came before, one of MultiModal-GPT’s primary characteristics is its capacity to engage in natural language discussions. This implies that consumers may engage with the model just like they would with a real person.
For example, MultiModal-GPT can give customers a detailed recipe for making noodles or recommend possible restaurants for dining out. The model is also capable of responding to generic questions about users’ trip intentions.
Recognition of Objects
MultiModal-GPT can recognize things in photos and respond to inquiries about them. For instance, the model can recognize Freddie Mercury in an image and respond to queries about him.
It can also count the number of individuals and explain what they are doing in a picture. This object identification capacity has applications in a variety of fields, including e-commerce, healthcare, and security.
MultiModal-GPT can also recognize text inside digital pictures. This implies the model can read the text in photos and extract useful data. It may, for example, detect the characters in an image and identify the author of a book.
It is an extremely useful tool for document management, data input, and content analysis.
Reasoning and Generation of Knowledge
Multi-modal-GPT can reason and produce knowledge about the world. This means it can provide full explanations of photographs and even tell them what season the image was taken in.
This skill is useful in a variety of disciplines, including environmental monitoring, agriculture, and meteorology. The model can additionally generate creative stuff like poetry, tales, and songs, making it an excellent tool for creative tasks.
Inner Workings of MultiModal-GPT
Template for Unified Instructions
The team presents a single template for the integration of unimodal linguistic data and multimodal vision-and-language data to properly train the MultiModal-GPT model in a synergistic manner.
This combined strategy attempts to improve the model’s performance across a variety of tasks by exploiting the complementary capabilities of both data modalities and encouraging a deeper comprehension of the underlying ideas.
The Dolly 15k and Alpaca GPT4 datasets are used by the team to measure language-only instruction-following abilities. These datasets act as a prompt template for structuring dataset input to guarantee a consistent instruction-following format.

How Does the Model Work?
Three key components make up the MultiModal-GPT model: a language decoder, a perceiver resampler, and a vision encoder. The image is taken in by the vision encoder, which then generates a collection of characteristics that characterize it.
The language decoder uses the information from the vision encoder to create text that describes the image with the aid of the perceiver resampler.
The component of the model that comprehends language and produces the text is the language decoder. To predict the following word in a phrase, the model is trained using both language-only and vision-plus language instruction-following data.
This teaches the model how to react to commands from humans and provides the acceptable text for picture descriptions.
The MultiModal-GPT was created by a team of Microsoft Research Asia researchers and engineers led by Tao Gong, Chengqi Lyu, and Shilong Zhang. Yudong Wang, Miao Zheng, Qian Zhao, Kuikun Liu, Wenwei Zhang, Ping Luo, and Kai Chen all contributed to the model’s study and development.
Natural language processing, computer vision, and machine learning are all areas of competence for the team. They have several articles published in top-tier conferences and publications, as well as various honors and accolades for their scientific efforts.
The research of the team focuses on the development of cutting-edge models and approaches to enable more natural and intelligent interactions between humans and technology.
Multi-modal-GPT development is a noteworthy accomplishment in the field since it is one of the first models to combine vision and language in a single framework for multi-round discussion.
The team’s contributions to MultiModal-GPT research and development have the potential to have a substantial influence on the future of natural language processing and human-machine interactions.
How To Use MultiModal-GPT
For beginners, using the MultiModal-GPT tool is simple. Simply go to https://mmgpt.openmmlab.org.cn/ and press the “Upload Image” button.
Choose the picture file to upload, and then type the text prompt into the text field. To create a response from the model, click the “Submit” button, which will appear below the text field.
You may experiment with different photos and instructions to learn more about the model’s capabilities.
To install the MultiModal-GPT package, use the terminal command “git clone https://github.com/open-mmlab/Multimodal-GPT.git” to clone the repository from GitHub. You can simply follow these steps:
git clone https://github.com/open-mmlab/Multimodal-GPT.git
pip install -r requirements.txt
pip install -v -e .
conda env create -f environment.yml to establish a new conda environment. You may run the demo locally after installing it by downloading the pre-trained weights and storing them in the checkpoints folder.
The Gradio demo may then be launched by running the command “python app.py”.
The MultiModal-GPT model still has flaws and room for development despite its excellent performance.
For instance, when dealing with complicated or ambiguous visual inputs, the model might not always be able to recognize and comprehend the context of the input. This may result in inaccurate predictions or reactions from the model.
Additionally, particularly when the input is complicated or open-ended, the model may not always produce the best reaction or result. The model’s answer, for instance, may have been impacted by how similar the two books’ covers looked in the case of the incorrect identification of a book cover.
Overall, the MultiModal-GPT model represents a big step forward in natural language processing and machine learning. And, it is very exciting to use it and experiment with it. So, you should give it a try either!
However, it has limits, as do all models, and requires additional refining and enhancement to obtain maximum performance in a variety of applications and domains.
