OpenAI unveils improved version of ChatGPT, customization features at ‘DevDay’

Users on the free tier of ChatGPT are also expected to have limited access to the GPT-5 model. However, those with Plus and Pro subscriptions will really be able to take advantage of the coming features. The Turing test is considered important because it allows researchers to study the potential applications and ethical ramifications of AI in real time. The study determined that through the GPT-4.5 model, humans could be able to have successful conversations with AI. In early April 2025, reports indicated that GPT-4.5 passed the Turing Test intelligence evaluation in a UC San Diego study.

Best for Enterprise Use Cases: ChatGPT-4

Along with our own updates based on community feedback, you can be assured that you have the most comprehensive copilot features available. After only one day, OpenAI has put a halt on the free version of its in-app image generator, powered by the GPT-4o reasoning model. The update is intended to improve realism in images and text in AI-generated context; however, users have already created a runaway trend that has caused the AI company to rethink its rollout strategy. A growing number of businesses are developing their own fine-tuned versions of GPT-4 to meet very specific business use cases and goals. These include Duolingo, Stripe, and Morgan Stanley, which are using GPT-4 to deepen conversation quality, combat fraud, improve user experience, and organize complex knowledge base data, respectively. Compared to previous GPT generations from OpenAI, GPT-4 has been trained on more and wider-ranging datasets, has more computation power and parameters, and has a greater context window for user inputs.

GPT-4 will also be more human-like, generating answers that will sound more like a human wrote them. Under the hood, OpenAI made performance optimizations that allow ChatGPT-4 Turbo to process prompts using less hardware resources. That reduction in infrastructure requirements has enabled the company to lower its API pricing. Sending prompts to GPT-4 Turbo costs three times less than with the original GPT-4, while output pricing has been halved.

GPT-4 Turbo

A new Assistants API, meanwhile, combines OpenAI’s large language models with features designed to ease the task of building applications with built-in chatbots. The tool made its debut at the company’s first annual DevDay developer conference, which took place today in San Francisco. At the event, OpenAI also introduced an enhanced version of the GPT-4 language model that underpins ChatGPT. Beyond the language model market, the company is enhancing its collection of image generation and speech generation services for developers.

• The brand indicated early in the year that GPT-5 could be available in the coming months.
• ChatGPT and GPT 3.5 are currently powering Microsoft’s New Bing, and a lot of people complain that they are slow in generating and displaying results.
• In December, OpenAI plans to launch a platform called GPT Store that will enable users to share their customized chatbots with the public.
• The company hosted an event last week in Germany, where it detailed the GPT-4 upgrade, per Heise.de.
• It also does a better job at distinguishing between AI-written and human-written text, as well as in the detection of automated misinformation campaigns that take advantage of AI tools.

This meant that the model could not only process and generate text but also analyze and interpret images, opening up a new dimension of interaction with the AI model. OpenAI announced the new GPT-4 upgrade on its blog this morning, and you can already try it out on ChatGPT, the AI chatbot that OpenAI has published to the web. (But only ChatGPT Plus, the paid version. It’s also capped at 100 messages per every four hours.) Microsoft confirmed, too, that its latest version of its Bing Chat tool uses GPT-4 as its underpinnings. While not yet confirmed, these moves appear to propel the GPT-5 timeline closer to launch. Claude offers a free version for individual users, while its paid plan starts at $18 per month, billed annually.

Microsoft says GPT-4 coming next week with video features

It’s unclear whether GPT-4 will be a built-in upgrade of ChatGPT or whether it’ll be exclusive to Microsoft’s Bing search engine that already supports ChatGPT. However, Microsoft Germany confirmed that GPT-4 is coming this week and that it’ll be multimodal. “It has a 128k context window so it can fit the equivalent of more than 300 pages of text in a single prompt,” the company said in a statement. “We also optimized its performance so we are able to offer GPT-4 Turbo at a 3x cheaper price for input tokens and a 2x cheaper price for output tokens compared to GPT-4.” SiliconANGLE Media is a recognized leader in digital media innovation serving innovative audiences and brands, bringing together cutting-edge technology, influential content, strategic insights and real-time audience engagement. The New York Times report highlights the experiences of Jonathan Mosen, a blind user of Be My Eyes from New Zealand.

Despite these precautions, there have also been instances of GPT-4 confabulating or making false identifications, underscoring the challenge of making a useful tool that won’t give blind users inaccurate information. OpenAI says “GPT-4 excels at tasks that require advanced reasoning, complex instruction understanding and more creativity”. For those new to ChatGPT, the best way to get started is by visiting chat.openai.com. The alternative is going for Microsoft’s implementation of GPT-4, which has been powering Bing for a few weeks. OpenAI today announced the general availability of GPT-4, its latest text-generating model, through its API. The market is filled with competing chatbots that might better meet your needs than ChatGPT-4 and ChatGPT-3.5.

Microsoft offered an example of how the multimodality of ChatGPT could help businesses. The AI could automatically summarize support calls with text after listening to the recordings. This would save 500 work hours a day for a large Microsoft customer in the Netherlands, which receives 30,000 calls a day that need to be summarized. Furthermore, Holger Kenn, another Microsoft Germany exec, explained that a multimodal ChatGPT bot can translate text into images, music, and video if asked. To go along with the new customization program, OpenAI is seeking to monetize the advances by opening an online GPT Store, in which the customized products will be available for public purchase and download. Each customized version of GPT-4 that is developed through the program will only be made available to the customer who commissioned it.

GPT-4: It’s safer?

It’s unclear, however, how users will get to test GPT-4 and whether OpenAI will just make it available within ChatGPT later this week. Microsoft quietly unveiled Kosmos-1 in early March, a multimodal AI supporting image input. Microsoft announced a mysterious AI event for March 16th, and it looks like we’re getting a big ChatGPT upgrade this week in the form of GPT-4, which comes with multimodal support.

Mosen has enjoyed using the app to identify items in a hotel room, like shampoo dispensers, and to accurately interpret images on social media. However, Mosen expressed disappointment when the app recently stopped providing facial information, displaying a message that faces had been obscured for privacy reasons.
