After DALL-E 3 and GPT-4, OpenAI has now introduced Sora as it steps into the realm of video generation with artificial intelligence. Let’s take a look at what we know about the platform so far and what it has to offer.
What is Sora?
It is a new generative AI Text-to-Video model that can create minute-long videos from a textual prompt. It can convert the text in a prompt into complex and detailed visual scenes, owing to its understanding of the text and the physical existence of objects in a video. Moreover, the model can express emotions in its visual characters.
The above video was generated by using the following textual prompt on Sora:
Several giant wooly mammoths approach, treading through a snowy meadow, their long wooly fur lightly blows in the wind as they walk, snow covered trees and dramatic snow capped mountains in the distance, mid afternoon light with wispy clouds; and a sun high in the distance creates a warm glow, The low camera view is stunning, capturing the large furry mammal with beautiful photography, depth of field.
While it is a text-to-video generative model, OpenAI highlights that Sora can work with a diverse range of prompts, including existing images and videos. It enables the model to perform varying image and video editing tasks. It can create perfect looping videos, extend videos forward or backward, and animate static images.
Moreover, the model can also support image generation and interpolation between different videos. The interpolation results in smooth transitions between different scenes.
What is the current state of Sora?
Currently, OpenAI has only provided limited availability of Sora, primarily to graphic designers, filmmakers, and visual artists. The goal is to have people outside of the organization use the model and provide feedback. The human-interaction feedback will be crucial in improving the model’s overall performance.
Moreover, OpenAI has also highlighted that Sora has some weaknesses in its present model. It makes errors in comprehending and simulating the physics of complex scenes. Moreover, it produces confusing results regarding spatial details and has trouble understanding instances of cause and effect in videos.
Now, that we have an introduction to OpenAI’s new Text-to-Video model, let’s dig deeper into it.
OpenAI’s methodology to train generative models of videos
As explained in a research article by OpenAI, the generative models of videos are inspired by large language models (LLMs). The inspiration comes from the capability of LLMs to unite diverse modes of textual data, like codes, math, and multiple languages.
While LLMs use tokens to generate results, Sora uses visual patches. These patches are representations used to train generative models on varying videos and images. They are scalable and effective in the model-training process.
Compression of visual data to create patches
We need to understand how visual patches are created that Sora relies on to create complex and high-quality videos. OpenAI uses an AI-trained network to reduce the dimensionality of visual data. It is a process where a video input is initially compressed into a lower-dimensional latent space.
It results in a latent representation that is compressed both temporally and spatially, called patches. Sora operates within the same temporal space to generate videos. OpenAI simultaneously trains a decoder model to map the generated latent representations back to pixel space.
Generation of spacetime latent patches
When the Text-to-Video model is presented with a compressed video input, the AI model extracts from it a series of spacetime patches. These patches act as transformer tokens that are used to create a patch-based representation. It enables the model to train on videos and images of different resolutions, durations, and aspect ratios. It also enables control over the size of generated videos by arranging patches in a specific grid size.
What is Sora, architecturally?
Sora is a diffusion transformer that takes in noisy patches from the visual inputs and predicts the cleaner original patches. Like a typical diffusion transformer that produces effective results for various domains, it also ensures effective scaling of videos. The sample quality improves with an increase in training computation.
Below is an example from OpenAI’s research article that explains the reliance of quality outputs on training compute.
The same video with 4x compute produces a highly-improved result where the video characters can hold their shape and their movements are not as fuzzy. Moreover, you can also see that the video includes greater detail.
What happens when the computation times are increased even further?
Source: OpenAI
The results above were produced with 16x compute. As you can see, the video is in higher definition, where the background and characters include more details. Moreover, the movement of characters is more defined as well.
It shows that Sora’s operation as a diffusion transformer ensures higher quality results with increased training compute.
The future holds…
Sora is a step ahead in video generation models. While the model currently exhibits some inconsistencies, the demonstrated capabilities promise further development of video generation models. OpenAI talks about a promising future of the simulation of physical and digital worlds. Now, we must wait and see how Sora develops in the coming days of generative AI.

This unexpected shakeup sent ripples through the AI industry, sparking inquiries into the company’s future, the interplay between profit and ethics in AI development, and the delicate balance of innovation.
So, why did OpenAI part ways with one of its most prominent figures? This is a paradoxical question making everyone question the reason for such a big move.
Let’s delve into the nuances and build a comprehensive understanding of the situation.
OpenAI history and timeline
A glimpse into Sam Altman’s exit
OpenAI’s board of directors cited a lack of transparency and candid communication as the grounds for Altman’s removal. This raised concerns that his leadership style deviated from comapny’s core mission of ensuring AI benefits humanity. The dismissal, far from an isolated incident, unveiled longstanding tensions within the organization.
To understand the reasons behind Altman’s dismissal, it’s crucial to grasp the organizational structure. The organization comprises a non-profit entity focused on developing safe AI and a for-profit subsidiary, which was later built by Altman. Profits are capped to prioritize safety, with excess returns to the non-profit arm.
Now that we have some context of the structure of this organization, let’s proceed to theorize some pressing possibilities of Sam Altman’s removal from the company.
Altman’s emphasis on profits vs. OpenAI’s not-for-profit origins
OpenAI was initially established as a nonprofit organization with the mission to ensure that artificial general intelligence (AGI) is developed and used for the benefit of all of humanity.
The board members are bound to this mission, which entails creating a safe AGI that is broadly beneficial rather than pursuing profit-driven objectives aligned with traditional shareholder theory.
On the other hand, Altman has been vocal about the commercial potential of an AI technology. He has actively pursued partnerships and commercialization efforts to generate revenue and ensure the financial sustainability of the company. This profit-driven approach aligns with Altman’s desire to see the company thrive as a powerful tech company in Silicon Valley.
The conflict between the company’s board’s not-for-profit emphasis and Altman’s profit-driven approach may have influenced his dismissal. The board may have sought to maintain a beneficial mission and adherence to its nonprofit origins, leading to tensions and clashes over the company’s commercial vision.
Side projects pursued by Sam Altman caused disputes with OpenAI’s board
Altman’s side projects were seen as conflicting with its mission. The pursuit of profit and the focus on side projects were viewed as diverting attention and resources away from its core objective of developing AI technology that could benefit society.

19. Tokenization
Tokenization is the process of breaking down a piece of text into smaller units, such as words or subwords. Tokenization is a necessary step before LLMs can be used to process text. When text is tokenized, each word or subword is assigned a unique identifier. This allows the LLM to track the relationships between words and phrases.
There are many different ways to tokenize text. The most common way is to use word boundaries. This means that each word is a token. However, some LLMs can also handle subwords, which are smaller units of text that can be combined to form words.
For example, the word “cat” could be tokenized as two subwords: “c” and “at”. This would allow the LLM to better understand the relationships between words, such as the fact that “cat” is related to “dog” and “mouse”.
20. Transformer models
Transformer models are a type of neural network that are well-suited for NLP tasks. They are able to learn long-range dependencies between words, which is essential for understanding the nuances of human language. Transformer models work by first creating a representation of each word in the text. This representation is then used to calculate the relationship between each word and the other words in the text.
The Transformer model is a powerful tool for NLP because it can learn the complex relationships between words and phrases. This allows it to perform NLP tasks with a high degree of accuracy. For example, a Transformer model could be used to translate a sentence from English to Spanish while preserving the meaning of the sentence.

6. Code completion:
Generative AI models can be used to suggest code completions as developers’ type. This can save time and reduce errors, especially for repetitive or tedious tasks.
For example:
Prompt: “Suggest code completions for the following function.”
Answer: The AI tool will suggest a number of possible completions for the function, based on the code that has already been written. For example, the AI tool might suggest the following completions for the line if number % 2 == 0::
if number % 2 == 0 else False: This will return False if number is not an even number.
if number % 2 == 0: return True else return False: This will return True if number is an even number, and False otherwise.
7. Idea generation:
Generative AI models can be used to generate new ideas for software products and services. This can help businesses to stay ahead of the competition and to deliver better products and services to their customers.
For example:
Prompt: “Generate ideas for a new software product.”
Answer: The AI tool will generate a number of ideas for a new software product, based on the user’s input. For example, the AI tool might generate ideas for a software product that:
It helps people to learn a new language.
Helps people to manage their finances.
Helps people to find and book travel.
These are just a few of the ways that OpenAI can help software developers. As OpenAI’s models continue to improve, we can expect to see even more ways that AI can be used to automate and streamline the software development process.

Large language models (LLMs) like GPT-3 and GPT-4. revolutionized the landscape of NLP. These models have laid a strong foundation for creating powerful, scalable applications. However, the potential of these models isaffected by the quality of the prompt. This highlights the importance of prompt engineering.
Furthermore, real-world NLP applications often require more complexity than a single ChatGPT session can provide. This is where LangChain comes into play!

This comprehensive beginner’s guide provides a thorough introduction to LangChain, offering a detailed exploration of its core features. It walks you through the process of building a basic application using LangChain and shares valuable tips and industry best practices to make the most of this powerful framework. Whether you’re new to Language Learning Models (LLMs) or looking for a more efficient way to develop language generation applications, this guide serves as a valuable resource to help you leverage the capabilities of LLMs with LangChain.
Overview of LangChain modules
These modules are essential for any application using the Language Model (LLM).
LangChain offers standardized and adaptable interfaces for each module. Additionally, LangChain provides external integrations and even ready-made implementations for seamless usage. Let’s delve deeper into these modules.
Overview of LangChain Modules
LLM
LLM is the fundamental component of LangChain. It is essentially a wrapper around a large language model that helps use the functionality and capability of a specific large language model.
Chains
As stated earlier, LLM (Language Model) serves as the fundamental unit within LangChain. However, in line with the “LangChain” concept, it offers the ability to link together multiple LLM calls to address specific objectives.
For instance, you may have a need to retrieve data from a specific URL, summarize the retrieved text, and utilize the resulting summary to answer questions.
On the other hand, chains can also be simpler in nature. For instance, you might want to gather user input, construct a prompt using that input, and generate a response based on the constructed prompt.
Prompts
Prompts have become a popular modeling approach in programming. It simplifies prompt creation and management with specialized classes and functions, including the essential PromptTemplate.
Document loaders and Utils
LangChain’s Document Loaders and Utils modules simplify data access and computation. Document loaders convert diverse data sources into text for processing, while the utils module offers interactive system sessions and code snippets for mathematical computations.
Vector stores
The widely used index type involves generating numerical embeddings for each document using an embedding model. These embeddings, along with the associated documents, are stored in a vector store. This vector store enables efficient retrieval of relevant documents based on their embeddings.
Agents
LangChain offers a flexible approach for tasks where the sequence of language model calls is not deterministic. Its “Agents” can act based on user input and previous responses. The library also integrates with vector databases and has memory capabilities to retain the state between calls, enabling more advanced interactions.
Building our App
Now that we’ve gained an understanding of LangChain, let’s build a PDF Q/A Bot app using LangChain and OpenAI.Let me first show you the architecture diagram for our app and then we will start with our app creation.
QA Chatbot Architecture
Below is an example code that demonstrates the architecture of a PDF Q&A chatbot. This code utilizes the OpenAI language model for natural language processing, the FAISS database for efficient similarity search, PyPDF2 for reading PDF files, and Streamlit for creating a web application interface.
The chatbot leverages LangChain’s Conversational Retrieval Chain to find the most relevant answer from a document based on the user’s question. This integrated setup enables an interactive and accurate question-answering experience for the users.
Importing necessary libraries
Import Statements: These lines import the necessary libraries and functions required to run the application.
PyPDF2: Python library used to read and manipulate PDF files.
langchain: a framework for developing applications powered by language models.
streamlit: A Python library used to create web applications quickly.
Importing necessary libraries
If the LangChain and OpenAI are not installed already, you first need to run the following commands in the terminal.
Setting openAI API key
You will replace the placeholder with your OpenAI API key which you can access from OpenAI API. The above line sets the OpenAI API key, which you need to use OpenAI’s language models.
Streamlit UI
These lines of code create the web interface using Streamlit. The user is prompted to upload a PDF file.
Streamlit UI
Reading the PDF file
If a file has been uploaded, this block reads the PDF file, extracts the text from each page, and concatenates it into a single string.
Reading the PDF File
Text splitting
Language Models are often limited by the amount of text that you can pass to them. Therefore, it is necessary to split them up into smaller chunks. It provides several utilities for doing so.
Text Splitting
Using a Text Splitter can also help improve the results from vector store searches, as eg. smaller chunks may sometimes be more likely to match a query. Here we are splitting the text into 1k tokens with 200 tokens overlap.
Embeddings
Here, the OpenAIEmbeddings function is used to download embeddings, which are vector representations of the text data. These embeddings are then used with FAISS to create an efficient search index from the chunks of text.
Embeddings
Creating conversational retrieval chain
The chains developed are modular components that can be easily reused and connected. They consist of predefined sequences of actions encapsulated in a single line of code. With these chains, there’s no need to explicitly call the GPT model or define prompt properties. This specific chain allows you to engage in conversation while referencing documents and retains a history of interactions.
