I have often found myself struggling with Python coding, as it consumes a significant amount of time due to my limited coding skills. Consequently, I often wonder if I could simply express my requirements in my native language instead. (My co-founder can relate to this as he has heard this many times from me, 😂) For instance, I would say something like 'Convert the given audio into text' or 'Classify these documents,' and the system would automatically carry out my commands without requiring me to write any code.
I'm sure many of you can relate to this frustration!
Well, it turns out that what seemed impossible before is now within reach, thanks to the fascinating concept of generative artificial intelligence. Generative AI has the potential to revolutionize the field of AI by enabling it to generate novel content and solutions in various domains."
So, let’s understand what generative artificial intelligence, or generative AI, is.
What is Generative AI in Simple Words?
Generative AI is a type of Artificial intelligence that allows us to generate novel content based on a given input or an AI system that is capable of generating text, images, and other types of media output is known as Generative AI.
Generative AI models can take input in any media form and can provide the output in the required media format. For example: You can just write an image description and the model will generate an image accordingly, also known as Text-to-Image generative AI model.
Similar to this, we can generate text like emails, blogs, and articles with just a single line prompt.
Here you can see an example of a Text-to-text model generated by ChatGPT.
How Does Generative AI Work?
Generative AI works by using a type of machine learning called generative modeling. This involves training a neural network on a large dataset of examples, such as images or text, and then using that network to generate new content that is similar to the original dataset.
During training, the neural network learns the statistical patterns and structures of the data, allowing it to generate new content that is similar in style, content, and quality. This is typically done using techniques such as diffusion, adversarial training, variational autoencoders, or transformer networks.
Once the model is trained, it can be used to generate new content by feeding it random noise or other input data, which is then transformed into a new output that resembles the original dataset. The output can be further refined using techniques such as post-processing or fine-tuning to improve its quality and realism.
Training Data for Generative AI
As you know training data is the fuel for any AI model and without high-quality training data, it is nearly impossible to reap the benefits of artificial intelligence.
Generative AI models are being trained primarily on unsupervised learning or self-supervised learning that needs a lot of training data without labeling or some data with labels. Models like Text-to-text use all the data available on the web.
The quality and diversity of the training data are critical factors in the performance of generative AI models. The training data should represent the range of variation and complexity the model is expected to generate.
For example, to generate realistic human faces, the training dataset should include a diverse range of facial features, such as different races, ages, and genders, and different facial expressions and lighting conditions.
The training data can be sourced from various places, such as public datasets, proprietary data, or synthetic data generated by other AI models. However, it's important to ensure that the training data is of high quality, diverse, and representative of the intended use case.
Additionally, to avoid potential bias or ethical issues, the training data should be carefully curated and labeled, and any potential biases in the data should be identified and addressed.
Types of Generative AI: Based on Input and Output.
As mentioned earlier Generative AI models can take any media as input and generate output in the required media format. A model that supports one media format is known as unimodal generative AI and on the other hand, a modal that supports more than one media type is known as multimodal Generative AI.
Let’s understand some of them with the latest developments.
Text-to-Text Generative AI
Text-to-text generative AI generates natural language text in response to a given input text.
The "text-to-text" aspect refers to the fact that these models are designed to take in a sequence of text as input, and then generate another sequence of text as output. This can be used for a wide range of natural language processing tasks, such as language translation, summarization, question answering, and text completion.
For example, a text-to-text generative AI model trained on English and Hindi text data can be used to translate English sentences into Hindi. It does this by taking in an English sentence as input and generating a corresponding Hindi sentence as output.
Latest Developments:
ChatGPT by OpenAI: ChatGPT is a text-based generative AI model developed by Open AI, also known as Large Language Model.
It has taken the world by storm and got 100 million users in less than 3 months. It is capable of many creative tasks like content creation, summarization, question-answering, sentiment analysis, language translation, etc.
OpenAI is still improving its performance.

t is still under development and it was only available for US and European users when first launched in March 2023. But in the latest Google I/O 2023 conference they released for all users across globe. You can access bard here
Character AI: Character AI is your virtual AI assistant in different avatars. They have recently launched their beta version, I have personally used this, it is a bit slower but performs very well on text generation tasks.
HeyPI: HeyPI is a text-based personal assistant generative AI model developed by Inflection AI. Its knowledge is limited compared to the mentioned models. The Inflection AI team includes some of the industry’s top AI experts who previously worked at DeepMind, Google, OpenAI, and Meta.
All the above-mentioned are very good at text generation tasks but mostly work for the English language, although some of them claim to be multilingual but give slow and poor results.
Not having enough high-quality multilingual data is a problem here!
Text-to-Image Generative AI
Text-to-Image generative AI generates images in response to a given input text.
These models are trained with the help of datasets of textual descriptions paired with corresponding images.
Text-to-Image Generative AI has many applications in areas such as fashion, interior design, and art, where visual representations of products are important. For example, it can be used to generate images of clothes based on textual descriptions or to create realistic interior designs based on textual specifications.
Latest Developments:
DALL-E: DALL-E is an image generative AI model developed by OPEN AI, this model is capable of generating quality images with the help of prompts. Prompts are sequences of words that help the model to understand the input.
Midjourney: Midjourney is also an image-generative AI model, but is way better at generating art for a given prompt. We can also call it art-generating AI.
There are many other platforms that generate images from text like PicsArt, Canva, DeepAI, Hotpot AI, etc.
However, Text-to-Image Generative AI is still a relatively new field, and there are many challenges that need to be overcome. One of the main challenges is the lack of large-scale datasets of textual descriptions paired with corresponding images. Another challenge is the difficulty of generating high-quality and diverse images that match the textual description.
These two text-to-text and text-to-image generative AI models are growing very rapidly and since humans are more attached to text from their primary school to professional work, these generative models are getting more attention and people have already started using them in daily life.
Other than the above two a lot of other generative models are underdeveloped that support text-to-video generation, text-to-code, image-to-image, and text-to-music generation, and will soon change the creative world.
Let’s see where it can create a positive impact!
Top Applications of Generative AI
