This research establishment focused on artificial intelligence Victoria d'Este made several key announcements today during this significant event. April 25, 2025 . In a groundbreaking move, OpenAI has released the by Turbo AI model, introducing an extraordinary capability that allows users to create personalized versions of the popular ChatGPT chatbot.

Interestingly, GPT-4 Turbo's contextual knowledge now extends up to April 2023, a major upgrade compared to its predecessors, which were limited to info available only until January 2022. While earlier versions struggled with queries about events after February 2022, the new model can now provide timely and accurate answers.

Additionally, the token window for this latest model has been expanded to a staggering 128,000 tokens, quadrupling the capacity of GPT-4 and surpassing that of any commercially available alternative. Alisa Davidson With this increased input capacity, GPT-4 Turbo can manage inputs as lengthy as 300 pages, a significant improvement over previous models that had a limitation of roughly 3,000 words.

This new iteration also supports April 25, 2025 AI-generated imagery and text-to-speech functions. Users are given the option to receive replies in six different preset voices, further diversifying the model's capabilities.

OpenAI has revealed that GPT-4 Turbo will be more by affordable for developers and businesses, stating,
'Input tokens for GPT-4 Turbo cost three times less than GPT-4 at $0.01, while output tokens are twice as cheap at $0.03.' This change aims to provide meaningful savings for those who rely on AI for handling large volumes of data.

OpenAI mentioned that developers will have early access to GPT-4 Turbo starting today, with the intention of rolling it out to the general public in the next few weeks.

To further assist developers, the company highlighted the April 25, 2025 , demonstrating OpenAI's commitment to empowering developers in creating 'agent-like experiences' in their applications.

The 'GPT Store' is designed to revolutionize how creators develop unique GPT models by providing a public platform. OpenAI has also mentioned that soon users will be able to monetize their creations based on their levels of engagement and usage.

These user-centric features mark a significant advancement in the evolution of OpenAI’s ecosystem.

Users now have comprehensive control over their chatbots, enabling them to customize various attributes. This includes branding the bot with a unique name and description, adjusting the welcome message, and specifying a set of preset prompts for others to use. Furthermore, users can pick from several options, allowing them to shape the functionalities of a particular chatbot, such as incorporating DALL-E, performing internet searches, or even executing coding tasks.

Potential applications include tools for analyzing data through natural language, coding assistants, and even AI-driven travel planning.

The Code Interpreter feature of the Assistants API, which first launched in March for ChatGPT, allows for the creation of graphs, charts, and file processing. This is aimed at enabling assistants generated with the Assistants API to iteratively run code to solve complex coding and mathematical problems.

OpenAI announced that the Assistants API is currently in a beta stage and is now available to all developers.

The company also introduced 'GPTs', which empower users to create customized versions of ChatGPT for improved daily assistance at work, home, or for specific tasks. For example, GPTs can clarify board game rules, help children with math, or aid in designing stickers.

'GPTs are now accessible for ChatGPT Plus and Enterprise users to experiment with, including  April 25, 2025 by Alisa Davidson . We plan to broaden access to GPTs for more users shortly,' OpenAI stated.

OpenAI affirmed that creating a personalized GPT is a simple process, designed for everyone, even those without coding skills. Users can design GPTs for personal use, in-house business operations, or for a wider audience. Starting this process is as easy as initiating a conversation, giving instructions and additional details, and selecting options like web searches, image creation, or data analysis.

'Early adopters such as Amgen, Bain, and Square are already utilizing their own GPTs for tasks like creating marketing materials that reflect their brand identity, assisting support teams in answering customer inquiries, and helping newly-hired software engineers with onboarding,' OpenAI shared in a', ". 'Businesses can begin implementing GPTs on Wednesday. You can enable users within your organization to develop internal-only GPTs without coding abilities and securely share them across your workspace.' April 25, 2025 OpenAI’s Commitment to Responsible AI Development

OpenAI stated that user interactions with GPTs are kept private and are not disclosed to developers. When a GPT interacts with third-party APIs, users maintain the control to approve whether data can be shared with those APIs.

Moreover, the company indicated that when developers tailor their own GPT by incorporating specific actions or knowledge, they have the discretion to choose whether user interactions with that GPT contribute to the model's enhancement.

OpenAI also plans to bolster existing privacy protections for users, including the option for users to exclude their entire accounts from model training. They have implemented new review processes to ensure compliance with policies governing GPTs. Additionally, the company has taken steps to foster user trust by allowing developers to verify their identities.

'By expanding the pool of individuals involved in determining “what to build” beyond just those with advanced technological access, we are likely to develop safer and more aligned AI. This same motivation to collaborate with people rather than for them led us to launch the OpenAI API and to explore ways to include public input in AI behavior, about which we intend to share more shortly,' OpenAI stated.
