GPT-4 is now official, having been announced by OpenAI on Tuesday with several updates focusing on accuracy, creative expression, and collaboration — along with a focus on safer and more accurate content.
ChatGPT Plus users will be able to try the new model today, along with developers through the API. OpenAI President and Co-Founder, Greg Brockman, plans to discuss with developers some of the capabilities and limitations of GPT-4 in a live stream demo at 1 p.m. PT.
Among its new features, the latest iteration of the GPT language model introduces several new modes of input capabilities. In addition to text, you can now upload images for analysis and receive answers via text. Additionally, GPT-4 can offer you a more creative text result from a more detailed prompt.
The language model also now supports up to 25,000 words of text, which suggests greater accuracy. Prior models could handle only about 1,000 words of text at a time and there are recommendations for giving prompts of 500 words at a time to keep the ChatGPT generator from getting confused.
GPT-4 was developed over the course of six months and was trained on Microsoft Azure AI supercomputers. OpenAI claims this training has made the model “safer and more aligned,” with it 82% less likely to respond to prompts for negative content and 40% more likely to generate desired information.
However, the brand notes that limitations, including “social biases, hallucinations, and adversarial prompts,” remain in the language model and are something that it continues to work on with “transparency, user education, and wider AI literacy.”
OpenAI detailed its collaboration with several brands that have built its app features using GPT-4, including Duolingo which has deepened language conversations, BeMyEyes, which has transformed visual accessibility, and Stripe, which has an updated user experience to combat fraud. Other brands and organizations include Morgan Stanley, Khan Academy, and the Government of Iceland.
Microsoft has also confirmed that its new Bing Search featuring an AI chatbot is based on GPT-4. The updated search engine debuted in February.
Speech-to-text apps have flooded the App Store, making it easier than ever to type on our Macs with just our voice. I have previously covered one such app called TypeWhisper. However, there has been a dearth of good text-to-speech models, and most of the good ones are locked behind a subscription.
Ollama, an open-source app that lets you run local AI models on your computer, wants to change that. It works on macOS, Windows, and Linux, and your prompts are never stored or used for training.
Did you think hitting delete on your AI chatbot conversation actually makes it disappear? Georgia Tech researchers just proved that's not entirely true. They have built a forensic tool called ORISA that can dig deleted conversations from your phone and even rebuild them into a working chatbot session you can keep talking to.
How can ORISA bring deleted AI conversations back?
Touchscreen laptops have been around for years. You can get them in all sizes and shapes. Just not from Apple. For years, the Cupertino giant has treated the idea of a touchscreen MacBook the way I treat a meeting that could have been an email: with open contempt. However, Wednesday looks like the day the company could finally change its mind.
The latest Apple invite puts the “Pro and Tell” showcase in Los Angeles at 10 a.m. PT (1 p.m. ET) on October 28, 2026. Instead of a regular live-streamed keynote, it is an invitation-only, hands-on event for a handful of press and creators (similar to what the company did for the MacBook Neo earlier this year).
