OpenAI Dev Day:
OpenAI Dev Day was a one-day event that took place on November 6, 2023, in San Francisco, California. It was the first developer conference organized by OpenAI, a leading artificial intelligence research laboratory. The event featured a keynote speech, breakout sessions, and a showcase of the latest AI products and features from OpenAI, such as GPT-4 Turbo, GPT Store, Assistants API, and more. The event aimed to bring together developers from around the world to explore new tools and exchange ideas with the OpenAI team.
ChatGPT’s Impressive User Milestone
One of the most notable revelations at the OpenAI Dev Day was the milestone reached by ChatGPT, OpenAI’s conversational AI model. After just a year since its launch, ChatGPT has gained immense popularity. OpenAI reported that over 100 million people are now using ChatGPT on a weekly basis. This rapid adoption makes ChatGPT one of the fastest consumer products to achieve the 100 million monthly user mark, and it did so just a few months after its launch. This success highlights the growing demand for conversational AI tools and their practical applications.
But ChatGPT’s influence extends beyond individual users. OpenAI also revealed that more than 2 million developers are actively building solutions through its API. This demonstrates the versatility and adaptability of ChatGPT, making it a valuable tool for developers across various industries.
GPT-4 Turbo

OpenAI unveiled the GPT-4 Turbo, an enhanced version of the already popular GPT-4 models, during the event. The GPT-4 Turbo comes in two versions: one optimized for text analysis and the other capable of understanding both text and images. This flexibility caters to a wide range of applications, from natural language understanding to image recognition and description.
In terms of pricing, the text-only version of GPT-4 Turbo is available at $0.01 per 1,000 input tokens and $0.03 per 1,000 output tokens. For those interested in processing images, the cost is $0.00765 for generating output for a 1080 x 1080 pixels image. These competitive prices make the GPT-4 Turbo accessible for developers and businesses seeking advanced AI capabilities.
One of the significant improvements in the GPT-4 Turbo is its context window, which has been expanded to 128,000 tokens or roughly 100,000 words. This is four times larger than GPT-4’s context window, enabling the model to understand and generate text with even more context and coherence. Additionally, the GPT-4 Turbo boasts a knowledge cut-off of April 2023, a substantial leap from GPT-4’s last knowledge cut-off in September 2021. This means that GPT-4 Turbo is more up-to-date and relevant for users.
Empowering Users to Build Their Own GPTs

OpenAI made an exciting announcement that allows users to create their own versions of GPT for various fun or productivity use cases. The most remarkable aspect of this development is that users can build these AI models using prompts, without any coding knowledge. This democratizes AI development, enabling a broader audience to harness the power of AI for their specific needs.
Moreover, OpenAI is extending this feature to enterprise customers, allowing them to build internal-only GPTs based on the company’s extensive knowledge base. This feature can significantly enhance business operations and customer interactions, as these tailored GPTs can be fine-tuned to address specific business challenges.
GPT Store for User-Created AI Bots

In another intriguing move announced at the “OpenAI Dev Day,” OpenAI revealed its plans to create the GPT Store, a marketplace where users can publish and share their GPT creations. While this marketplace will initially feature creations from “verified builders,” it opens up the possibility for a wider range of AI solutions to become available to the public.
The CEO of OpenAI, Sam Altman, also discussed the potential for compensating people who create popular GPTs. This could lead to a new era of innovation, where developers and creators are incentivized to build highly useful and innovative AI solutions.
Notably, this approach aligns with recent trends in the industry. For instance, Quora’s Poe platform, which also allows users to build AI bots through prompts, recently opened a creator payment program. This indicates a growing recognition of the value and potential of user-generated AI content.
New API for Building Assistants
OpenAI introduced a new API known as the Assistants API, which empowers developers to create their own “agent-like experiences.” These assistants can perform tasks like retrieving external knowledge or executing programming functions to achieve specific actions. The potential use cases are diverse, ranging from coding assistants to AI-powered vacation planners. This API opens up new avenues for the development of specialized AI assistants that cater to different needs and industries.
DALL-E 3 API
OpenAI’s DALL-E 3, a text-to-image model, is now available through an API. This API offers a range of output resolutions, from 1024×1024 to 1792×1024, in different formats. This tool can be invaluable for creative and design-oriented applications. The pricing for DALL-E 3’s generated images is set at $0.04 per image, making it a cost-effective option for those looking to generate visual content from textual descriptions.
New Text-to-Speech APIs with Human-Like Voices
OpenAI launched a new text-to-speech API called the Audio API, which features six preset voices: Alloy, Echo, Fable, Onyx, Nova, and Shimer. These voices are designed to sound more human-like and natural, enhancing the quality of synthesized speech. The API is accessible at a competitive price of $0.015 per 1,000 input characters. This development offers businesses and developers an easy way to incorporate high-quality text-to-speech capabilities into their applications and services.
Commitment to Protecting Businesses
OpenAI introduced a program called Copyright Shield, aiming to protect businesses using the company’s products from copyright claims. OpenAI has pledged to cover legal fees for customers who use its “generally available” developer platform and ChatGPT Enterprise, should they face intellectual property lawsuits related to content generated using OpenAI’s tools. This program is a significant step towards ensuring the legal and ethical use of AI technologies and provides peace of mind to businesses relying on OpenAI’s offerings.
Industry-Wide Trends in IP Protection
The announcement of Copyright Shield at the OpenAI Dev Day aligns with a broader trend in the tech industry. Several major companies, including Microsoft, Google-backed Cohere, Amazon, and IBM, have also announced initiatives to indemnify customers against intellectual property infringement claims. This underscores the growing importance of addressing legal and copyright issues in the AI and technology landscape.
Conclusion
OpenAI Dev Day was a remarkable event that showcased the latest advancements and innovations in AI. The event featured new products and features that aim to make AI more accessible, powerful, and secure for developers and users.
Some of the highlights include the GPT-4 Turbo, the GPT Store, the Assistants API, the DALL-E 3 API, the Audio API, and the Copyright Shield program. These offerings demonstrate OpenAI’s vision and mission of creating and promoting beneficial AI for humanity.
