Adverts will soon appear at the top of the AI tool ChatGPT for some users, the company OpenAI has announced. The trial will initially take place in the US, and will affect some ChatGPT users on the free service and a new subscription tier, called ChatGPT Go. This cheaper option will be available for all users worldwide, and will cost $8 a month, or the equivalent pricing in other currencies. OpenAI says during the trial, relevant ads will appear after a prompt - for example, asking ChatGPT for places to visit in Mexico could result in holiday ads appearing. In example screenshots shared by the firm, the ads look like banners.

OpenAI has rolled out its store for custom GPTs and a new ChatGPT subscription tier for smaller teams. The GPT Store allows developers and users to share and profit from their custom versions of the viral chatbot. The GPT Store allows OpenAI to turn ChatGPT's white-hot prominence in the tech world into a tollkeeper's business model, taking a cut of revenue like in Apple's App Store. Anyone can build and share GPTs -- you don't need coding experience -- but creators must make a Builder Profile that shares their real name or points users to a verified website. OpenAI says a revenue program for GPT creators is coming soon in Q1. "As a first step, US builders will be paid based on user engagement with their GPTs," the company wrote, promising to provide more info as the program's launch approaches.

Just as Xbox starts to make some major strides with its cloud gaming service, Nvidia comes out with a whopper of an update to its cloud gaming platform, GeForce Now. As of last month, anyone can pre-order a membership to Nvidia's new RTX 3080 subscription tier, which provides more resolution options, features, and benefits than any other dedicated cloud gaming service out there--and for the moment it's also the only cloud gaming platform that supports true 4K gaming. We recently tried out the new subscription tier and all it has to offer. We were incredibly impressed with how smoothly the games ran, even at a level of detail so precise you can see pores on the characters' skin. If you're new to cloud gaming or wondering if subscribing to GeForce's RTX 3080 tier is worth it, here's what you need to know.
