In the fast-evolving realm of artificial intelligence, OpenAI continues to spearhead innovation, relentlessly pushing the boundaries of what is achievable. The OpenAI DevDay 2023, a landmark event held on November 6th in San Francisco, proved to be a pivotal moment in AI development, unveiling groundbreaking models and products that provide an attractive glimpse into the future of AI.

Life Before AI:

Before OpenAI disrupted the scene, computer interactions were constrained by traditional programming paradigms, characterized by limited natural language understanding, fixed functionality, and rudimentary search engines. Customer support heavily relied on human intervention, and language translation was a less sophisticated affair. Text-based interfaces dominated, and the advent of OpenAI marked a paradigm shift with the introduction of advanced AI language models like ChatGPT, revolutionizing natural language interactions with computers.

Key Highlights:

Unveiling New Features: A standout moment at OpenAI DevDay was the introduction of several groundbreaking models and developer products. GPT-4 Turbo took center stage, promising enhanced performance and capabilities over its predecessor. The Assistants API opened new avenues for developers, enabling seamless integration of intelligent AI assistants into their applications. GPT-4 Turbo with Vision showcased OpenAI’s commitment to multi-modal AI, fusing language understanding with vision capabilities for a more comprehensive AI experience.

The Rise of GPTs: OpenAI introduced a new paradigm in AI by unveiling GPTs, a family of models capable of generating text, code, images, audio, and video from natural language prompts. This versatility represents a significant step forward in creating AI systems that can comprehend and generate content across various modalities. The potential applications of GPTs in fields such as content creation, software development, and the creative arts are immense.

GPT-4 Turbo with 128K context: This enhanced version can handle the equivalent of over 300 pages of text in a single prompt. This expanded context allows the model to consider a broader scope of information, leading to more coherent and relevant responses.

Community Collaboration: OpenAI emphasized the collaborative nature of AI development, acknowledging the invaluable contributions of the wider community. The introduction of new developer tools and APIs was accompanied by a call for increased collaboration, inviting developers worldwide to actively participate in shaping the future of AI.

Function calling: Function calling allows users to explain their app’s functions or external APIs to the model. Now, the model can smartly generate a JSON object with the necessary details to perform those functions. Users can now request multiple actions in a single message, like asking to ‘open the car window and turn off the A/C.’. With GPT-4 Turbo, users can expect better results as it’s now more likely to provide the correct function parameters.

JSON Mode: GPT-4 Turbo outperforms older models in tasks that demand precise instruction adherence, like creating specific formats such as always responding in XML. It now includes support for new JSON mode, guaranteeing that the model produces valid JSON. The introduction of the API parameter response_format allows the model to limit its output, ensuring the generation of a syntactically correct JSON object. Developers using the Chat Completions API for JSON generation outside of function calling will find JSON mode particularly beneficial.

GPT-4 Turbo with vision: GPT-4 Turbo now supports image inputs in the Chat Completions API, opening up possibilities like generating captions, detailed analysis of real-world images, and reading documents with visuals. To access this feature, developers can use gpt-4-vision-preview in the API, with plans to integrate vision support into the main GPT-4 Turbo model’s stable release. 

Text-To-Speech: Now, developers can convert text into high-quality speech using GPT-4 Turbo’s text-to-speech API. The new TTS model provides a selection of six preset voices and two model variants: tts-1 for real-time applications and tts-1-hd for optimal quality.

Fine-Tuning Experimental Access: Also being introduced is an experimental access program for GPT-4 fine-tuning. For organizations requiring extensive customization, GPT-4 Turbo’s Custom Models program offers exclusive collaboration with OpenAI researchers for tailored GPT-4 training. This includes domain-specific pre-training and custom RL post-training.


OpenAI DevDay 2023 was a milestone event showcasing the latest AI technology advancements. The introduction of GPT-4 Turbo, Assistants API, GPT-4 Turbo with Vision, DALL·E 3 API, and the innovative GPTs family of models marked a significant leap forward. The insights shared by OpenAI’s leadership, engaging discussions, and networking opportunities made this conference a must-attend for anyone passionate about the future of artificial intelligence. As the industry evolves, events like DevDay serve as a beacon, guiding developers and researchers toward a future where AI plays an increasingly pivotal role in shaping our world.
