As the field of AI continues to evolve and improve, its impact on daily life is rapidly
increasing, making it an essential area of focus for businesses and individuals alike. AI
models are gradually replacing human labor with the capability to perform every
imaginable task previously only attainable by humans. As per Grand View Research, the
global chatbot market was estimated at USD 5,132.8 million in 2022 and is anticipated to
increase at a CAGR of 23.3% between 2023 and 2030. According to Market.US, the global
chatbot market was valued at USD 4.92 billion in 2022 and is forecasted to exhibit the
highest CAGR of 23.91% from 2023 to 2032, with an expected market size of USD 42
billion by the end of the forecast period. The rising demand for customer service will likely
be the major driver behind this projected growth.
The way ChatGPT has transformed human-machine interaction blurring the barriers
between the two is a powerful demonstration of AI’s immense potential and a clear sign of
its promising future. However, ChatGPT has certain limitations; it can neither create
images nor process visual prompts. Microsoft has made significant progress by
developing Visual ChatGPT, a language model that generates coherent and contextually
relevant responses to image-based prompts. The model uses a combination of natural
language processing techniques and computer vision algorithms to understand the
content and context of images and generate textual responses accordingly.
Visual ChatGPT combines ChatGPT with Visual Foundation Models (VFMs) like
Transformers, ControlNet, and Stable Diffusion. Its sophisticated algorithms and cutting-
edge deep learning techniques allow it to interact with users in natural language, offering
them the information they seek. With the visual foundation models, ChatGPT can also
evaluate pictures or videos that users upload to comprehend the input and offer a more
customized solution.
Let’s delve deeper into Visual ChatGPT to understand and explore the potential of this
recently developed technology.
What is Visual ChatGPT?
Visual ChatGPT is a conversational AI model that combines computer vision and natural
language processing to create a more enhanced and engaging chatbot experience. There
are many potential applications for Visual ChatGPT, such as creating and editing
photographs, which may not be available online. It can remove objects from pictures,
change the background color, and provide more accurate AI descriptions of uploaded
pictures.

2. 2/12
Visual foundation models play an important role in the functioning of Visual ChatGPT,
allowing computer vision to decipher visual data. VFM models typically consist of deep-
learning neural networks trained on massive datasets of labeled photos or videos and can
identify objects, faces, emotions, and other visual aspects of images.
Visual ChatGPT, also known as Image-Chat, is an AI model that combines natural
language processing with computer vision to generate responses based on text and image
prompts. The model is based on the GPT (Generative Pre-trained Transformer)
architecture and has been trained on a large dataset of images and text.
Visual ChatGPT uses computer vision algorithms to extract visual features from the image
and encode them into a vector representation when presented with an image. This vector
is then concatenated with the textual input and fed into the model’s transformer
architecture, which generates a response based on the combined visual and textual input.
For example, if presented with an image of a cat and a prompt such as “Change the cat
color from black to white?” Visual ChatGPT may generate an image of the white cat. The
model is designed to generate relevant responses to the image and the prompt and
produce coherent responses.
Applications of Visual ChatGPT range from social networking and marketing to customer
care and support.
Features of Visual ChatGPT
The key features of Visual ChatGPT are as follows:
Multi-modal input: One of the key features of the Visual ChatGPT is multi-modal
input. It enables the model to handle both textual and visual data, which can be incredibly
helpful in generating responses considering both input types. For instance, if you provide
Visual ChatGPT an image of a woman wearing a green dress and use the prompt, “Can
you change the color of her dress to red?” it can use both the image and the text to
produce an image of a woman wearing a red dress. This can be extremely useful in tasks
like labeling pictures and responding to visual questions.
Image embedding: A key component of Visual ChatGPT is image embedding. When
Visual ChatGPT gets an input image, it creates an embedding, a compact and dense
representation of the image. With the help of this embedding, the model can use the
image’s visual characteristics to generate responses that consider the prompt’s visual
context. Through the use of this picture embedding, Visual ChatGPT can comprehend the
input’s visual content in a better way and can produce responses that are highly precise
and relevant. Essentially, Visual ChatGPT incorporates image embedding to detect visual
elements and objects within an image. This information is utilized in constructing a
response to a prompt that involves an image. This can result in more accurate and
contextually relevant replies, especially in scenarios that require understanding text and
visual information.

3. 3/12
Object recognition: The model has been trained on a large image dataset, enabling it to
develop the ability to identify a range of items in pictures. When given a prompt that
includes a picture, Visual ChatGPT can use its object recognition abilities to recognize
particular elements in the image and provide responses. For instance, if given a picture of
a beach, Visual ChatGPT might be able to identify elements like water, sand, and palm
trees and use that information to respond to the prompt. This can result in more thorough
and precise responses, particularly against queries requiring a deep understanding of
visual data.
Contextual understanding: The model is intended to comprehend the connections
between a prompt’s text and visual content and use this information to provide more
accurate and pertinent responses. Visual ChatGPT can produce highly complex and
contextually appropriate responses by considering a prompt’s text and visual context. For
instance, if given an image of a person standing in front of a car and the prompt, “What is
the person doing?” Visual ChatGPT can use its visual understanding to determine that the
person is standing in front of a car and then use this textual understanding to produce an
answer that makes sense in this situation. A plausible reaction from the model might be
“The individual is admiring the car” or “The person is taking a picture of the car,” both of
which fit with the image’s overall theme.
Large-scale training: A critical feature of Visual ChatGPT is large-scale training, which
contributes to the model’s ability to produce high-quality responses to various prompts. A
sizable dataset of text and images that covers a wide range of themes, styles, and genres
was used to train the model. This has helped Visual ChatGPT develop the ability to
provide responses that are instructive, engaging, and relevant to the context in addition to
being grammatically correct. With extensive training, Visual ChatGPT has learned to
recognize and produce responses that align with the patterns and styles of human
language. This indicates that the model can produce answers comparable to those a
human might give, making the responses seem more natural and compelling.
What is the role of visual foundation models in Visual ChatGPT?
Visual Foundation Models are computer vision models created to mimic the early visual
processing that occurs in the human visual system. Convolutional neural networks
(CNNs) are generally used in their working. They are trained on a massive image dataset
to learn a hierarchical collection of attributes that may be applied to tasks like object
recognition, detection, and segmentation.
VFMs try to follow how the human visual system processes information by extracting low-
level features of objects like edges, corners, and texture and then combining them to form
more complex features like shapes. This hierarchical approach is similar to how the visual
cortex processes information, with lower-level neurons responding to simple features and
higher-level neurons responding to more complex stimuli.

4. 4/12
The initial stage of the working of VFMs in Visual ChatGPT is to train a CNN on a large
image dataset, often using a supervised learning method. By using a series of
convolutional filters on the input picture during training, the network learns to extract
features from the images. Each filter creates a response map focusing on a certain image
aspect, such as a shade, texture, or shape. A pooling layer is applied after the first layer of
filters, which lowers the spatial resolution of the response maps and aids in extracting
more robust features. Each layer learns to extract more abstract and complicated
information than the one before it, as the process is repeated for numerous levels. A fully
connected layer serves as the VFM’s last layer and often transfers the high-level
characteristics retrieved from the image to a collection of output layers, such as object
categories or segmentation labels. The VFM uses the learned set of filters to extract
features from an input image during inference and uses those features to generate a
prediction about an object or scene in the image.
VFMs offer a powerful framework for creating computer vision models that reach cutting-
edge performance on various applications. VFMs can effectively identify and comprehend
the visual world by extracting a massive set of information from images.
How does Visual ChatGPT work?
Visual ChatGPT is a neural network model that combines text and image information to
generate contextually relevant responses in a conversational setting. Here are the steps of
how Visual ChatGPT works:
Input processing
The image prompt provides a meaningful context of the input, while the textual input
consists of a collection of words that constitute the user’s message. Using the image input
is not always necessary, but it can offer additional details that can aid the model in
producing more contextually appropriate responses. The model can produce more
detailed and precise responses in a conversational situation when text and visual inputs
are integrated.
Textual encoding
A transformer-based neural network called the text encoder processes the textual input by
compiling a list of contextually relevant word embeddings. The transformer model assigns
a vector representation, or embedding, to each word in the input sequence. Based on each
word’s context within the sequence, the embeddings capture the semantic meaning of
each individual word. The transformer-based text encoder is often pre-trained utilizing
unsupervised learning approaches like the self-attention mechanism on large text
datasets, enabling it to recognize intricate word relationships and patterns in the input
text. The generated embeddings are fed into the model’s subsequent stage as input.
Image encoding

5. 5/12
Deep learning neural networks, such as convolutional neural networks (CNNs), are very
effective for image recognition applications. A pre-trained model like VGG, ResNet, or
Inception trained on sizable image datasets like ImageNet often serves as the CNN-based
image encoder. CNN uses convolutional and pooling layers to extract high-level features
from a picture after receiving it as input. The image is then represented as a fixed-length
vector by flattening these features and passing them through one or more completely
linked layers.
Multimodal fusion
The image and text encodings are typically concatenated or summed together to create a
joint representation of the input. This joint representation is then passed through one or
more fusion layers that combine the information from the two modalities. The fusion
layer can take many forms, such as:
Simple concatenation: This method combines the image and text embeddings
along the feature dimension to produce a single joint representation. The final
output can be produced by passing this combined representation via one or more
completely connected layers.
Bilinear transformation: With this technique, a set of linear transformations are
used to first translate the image and text embeddings to a common feature space.
After that, a bilinear pooling process is performed by multiplying the two
embeddings element by element. The pooling process captures the interactions
between the picture and text characteristics, which creates a combined
representation that may be fed through subsequent layers to produce the final
output.
Attention mechanism: This technique generates context vectors for each
modality by first passing the picture and text embeddings via independent attention
mechanisms. These context vectors are then integrated using an attention process
that creates a joint representation by learning how important each modality is based
on the input. Thanks to this attention mechanism, the model can concentrate on the
image’s and text’s most important areas when producing the output.
Decoding
The transformer-based neural network that comprises a stack of decoder blocks serves as
the decoder in the multimodal model. Each decoder block resembles its counterpart in the
transformer-based language models, with a few adjustments to account for the image
data. Each decoder block specifically focuses on the preceding output tokens and the
combined image-text representation to produce the subsequent token in the sequence.
The most typical method is to sample from this distribution after the decoder creates a
probability distribution over the vocabulary of potential output tokens to produce the
final output sequence. It is possible to accomplish this using a greedy method, in which
the token with the highest probability is chosen at each time step, or a more complex
method like beam search decoding and teacher forcing is used.

6. 6/12
Output generation
After processing and encoding the input, the model produces a series of output tokens
representing the response. A beam search technique looks through every possible
combination of tokens to identify the one that most closely matches the input context. It
operates by keeping track of a collection of potential sequences, known as beams, which
are expanded at each stage of the decoding procedure. The search is carried out until the
algorithm identifies the sequences with the highest probability, maintaining a
predetermined number of beams. In contrast, sampling tokens are selected at random
from the probability distribution of the model at each stage, leading to a wider range of
original responses. Regardless of the method employed, the final output tokens are
transformed into a word sequence to provide the answer from the model. This response
must deliver pertinent information appropriate for the input context continuously and
coherently.
Architectural components of Visual ChatGPT and its role

7. 7/12
The architectural components of Visual ChatGPT and their roles are discussed below:
User query
A query is the user’s initial input, typically visual representations like photographs or
videos. Visual ChatGPT then processes this input to produce a response or output
pertinent to the user’s inquiry. The user question is a crucial part of the system since it
establishes the nature of the task that Visual ChatGPT must perform and directs the
subsequent processing and reasoning phases. The user enters the query, and then Visual
ChatGPT processes the input to produce relevant output.
Prompt manager
After the user generates a query, it goes to the prompt manager. The visual data is
transformed into a textual representation and fed into the Visual ChatGPT model using an
image recognition program or prompt manager. Computer vision techniques are generally
used to evaluate the visual input and extract relevant information, such as text detection,
object detection, and facial recognition. The information is then transformed into a
natural language format to be utilized as input for additional analysis and the creation of
responses.
Prompt manager assists Visual ChatGPT by iteratively providing data from VFMs to
ChatGPT. To simplify the user’s requested task, the prompt manager integrates 22
separate VFMs and specifies their internal communication. The three key functions of a
prompt manager are as follows:
Demonstrating the capabilities of each VFM and the appropriate input-output
format for ChatGPT.
Translates several visual information formats, such as PNG images, depth images,
and mask matrices, into text that ChatGPT can read.
Handles the varying VFMs’ histories, priorities, and conflicts.
The prompt manager uses an effective technique to coordinate with VFMs for particular
tasks because Visual ChatGPT interacts with various VFMs. This is because various VFMs
have features in common, such as generating new images by replacing certain
components in an image. Conversely, the VQA task (visual image question answering)
might respond according to the image presented.
Computer vision techniques are generally used to evaluate the visual input and extract
pertinent information, such as text detection, object recognition, and facial recognition.
The information is then transformed into a natural language format to be utilized as input
for additional analysis and the creation of responses.
Computer vision

8. 8/12
The prompt manager performs its task using computer vision, a branch of artificial
intelligence (AI) that enables computers and systems to extract useful information from
digital photos, videos, and other visual inputs and execute actions or make
recommendations based on that information. If AI allows computers to think, computer
vision allows them to see, observe, and comprehend. Computer vision aims to program
computers to analyze and comprehend images down to the pixel level. Technically,
machines try to retrieve, interpret, and analyze visual data using specialized software
algorithms.
In his Image Processing and Computer Vision article, Golan Levin provides technical
information regarding machines’ procedures to understand images. In essence,
computers perceive images as a collection of pixels, each with a unique set of color values.
Think of a picture of a red flower as an example. The image’s brightness is encoded as a
single 8-bit value that ranges from 0 to 255 (0 being black and 255 being white). When
you enter an image of a red flower into the software, it sees these numbers. The Visual
ChatGPT employs a computer vision algorithm that assesses an image, analyzes it further,
and makes decisions based on its findings.
We must explore the algorithms this technique is based on to comprehend the latest
developments in computer vision technology. Contemporary computer vision relies on
deep learning, a branch of machine learning that uses algorithms to extract information
from data. Visual ChatGPT incorporates all these technologies to produce reliable
outcomes.
Deep learning employs a neural network algorithm and is a more efficient method of
performing computer vision. Using specified data samples, neural networks are used to
extract patterns. The human understanding of how brains work, particularly the
connections between the neurons in the cerebral cortex, inspired these algorithms. The
perceptron, a mathematical model of a biological neuron, lies at the fundamental level of
a neural network. There may be numerous layers of interconnected perceptrons, similar
to the biological neurons in the cerebral cortex. The output layer of the perceptron-
created network receives input values (raw data), which are then transformed into
predictions about a specific object.
Visual Foundation Model (VFM)
The Visual Foundation Model (VFM) is a deep learning model for visual identification
tasks like object detection, image classification, natural language processing, and
question-answering. It is built on a “visual vocabulary,” a collection of image attributes
learned from a massive sample of images. This visual vocabulary trains the VFM model to
identify items and scenes in photographs. Overfitting is less likely to occur using the VFM
model, and this is because it was trained using a predetermined set of image features
rather than creating brand-new features from scratch. The VFM model is more
interpretable than earlier deep learning models since it enables researchers to explore the
learned visual language and understand how the network generates predictions.

9. 9/12
A “visual vocabulary” is used by the Visual Foundation Model (VFM) to represent images.
Images or graphics that represent words and their meanings are called visual vocabulary.
In the same way, individual words enable written language, and individual images provide
visual language. A picture can be the basis for a search in a Visual Vocabulary rather than
a text. A search will produce a list of images and videos that can be sorted based on how
closely they resemble the original image. Visual vocabulary is a collection of visuals and
their attributes learned from a massive dataset of images using unsupervised learning
methods like clustering. Edges, corners, and textures are examples of lower-level visual
information from which the features are often retrieved.
The VFM model first extracts the histogram of information from a picture to classify an
image. The closest match is then determined by comparing this histogram to others from
a collection of training images. This is accomplished by utilizing a similarity metric, such
as cosine similarity or Euclidean distance.
To identify objects in the image, the VFM model initially divides the image into small
sections and extracts the histogram of information for each region. Then, it contrasts
these histograms with histograms derived from a collection of training images that
include relevant items. Regions similar to the training images are considered to contain
objects of interest, and the model outputs the position and class of the objects. Blip, Clip,
and Stable Diffusion are examples of the VFM models used in Visual ChatGPT.
History of dialogue
The history of dialogue makes the outcome more meaningful as per the input. When a
user inserts an inquiry, the history of dialogue aids the system in responding to questions
based on previously asked queries while considering the context of the dialogue. It follows
the patterns and influences the training data’s design to create a response. With the
history of dialogue, Visual ChatGPT can pinpoint common patterns and structures of
communication, including turn-taking, topic-switching, and conversational coherence, by
studying enormous databases of human-to-human interactions.
History of reasoning
The history of reasoning is the ability to use contextual information, including visual cues,
to produce responses that are pertinent and meaningful in the context of Visual ChatGPT.
Additionally, the system can learn to identify and resolve conflicts between various
information sources by analyzing the reasoning procedures of various VFMs. When the
provided information is confusing or conflicting, the system must utilize its reasoning
skills to determine the most probable interpretation of the data. When the user inquires,
the system responds to user inquiries with greater accuracy and relevance thanks to the
history of reasoning.
It examines the reasoning processes of multiple VFMs and develops the ability to
recognize and resolve conflicts across various sources of information. When the provided
information is confusing or conflicting, the system utilizes its reasoning skills to

10. 10/12
determine the most probable interpretation of the data.
Intermediate response
Finally, the system produces several intermediate responses that make sense to user
queries. The system can evaluate many interpretations of the input data by generating
multiple intermediate responses, and then it can decide which interpretation is most
likely to be relevant to the user. When the available information is ambiguous or
uncertain, this technique helps the system to identify and resolve contradictory or
incomplete information.

medical images like X-rays, CT scans, and MRIs. Visual ChatGPT can help doctors and
other health professionals make more precise diagnoses. Using computer vision, the
model can highlight potential irregularities or areas of concern for the doctor’s attention.
Visual ChatGPT can also be used to track and monitor patients. For instance, patients
undertaking physical therapy or rehabilitation exercises could record their motions with a
camera or a wearable device, and Visual ChatGPT could analyze the visual data to give
feedback on their form, posture, or progress. When patients cannot visit their doctor in
person, this can be extremely helpful for remote patient monitoring their symptoms.
Education: It is possible to create a virtual instructor using Visual ChatGPT to interact
with students, respond to their inquiries, and offer tailored feedback on their work. The
tutor can also pinpoint places where students need extra help by employing computer
vision to monitor student behavior. Interactive educational resources can be produced
using Visual ChatGPT. For example, the model can produce pictures or videos that clarify
difficult concepts or show how scientific procedures work. These resources can be altered
to meet the requirements of certain students or groups of students. Furthermore, Visual
ChatGPT can help with language acquisition by producing visuals or videos that clarify
the meaning of unfamiliar words or expressions. Also, the program can give students
comments on their usage of grammar or pronunciation, assisting them in developing their
language abilities.
