ChatGPT-5 is getting great reviews, Epicor expands its AI offerings, Walmart adds more tech of interest to all retailers and the FBI warns about QR codes.

At long last, GPT-5 has arrived — and it's free to all ChatGPT users.

In a major shift, the company is “open sourcing” two A.I. systems, freely sharing the technology with outside researchers and businesses.

OpenAI on Thursday released GPT-5, unveiling a new version of the artificial intelligence model that fuels popular chatbot ChatGPT. The product will be made immediately available to users, including customers who use the company's cost-free options, OpenAI said.

With the buzz around GPT-5 echoing new iPhone models, has ChatGPT achieved a similar edge in commercialising AI?

OpenAI is expected to release GPT-5 soon, with anticipation building around major upgrades in reasoning, performance, and real-world applications.

The latest model is missing some of what people like the most, and it's an important lesson in understanding your users.

OpenAI lost a number of subscribers who were upset at the changes made with GPT-5. While this number is likely to be small, and OpenAI has clearly seen an uplift in users since the launch, appeasing existing subscribers seems to be high on the agenda for the brand.

Following the launch of GPT-5, users expressed discontent over its performance and reduced messaging capabilities compared to previous models. OpenAI responded by increasing message limits for Plus subscribers and allowing access to older models.
