During its first-ever developer conference on Monday, OpenAI previewed GPT-4 Turbo, a brand new version of the large language model that powers its flagship product, ChatGPT. The newest model is capable of accepting much longer inputs than previous versions — up to 300 pages of text, compared to the current limit of 50. This means that theoretically, prompts can be a lot longer and more complex, and responses might be more meaningful.

OpenAI has also updated the data that GPT-4 Turbo is trained on. The company claims that the newest model now has knowledge about the world until April 2023. The previous version was only caught up until September 2021, although recent updates to the non-Turbo GPT-4 did include the ability to browse the internet to get the latest information.

GPT-4 Turbo will also accept images as prompts directly in the chat box, wherein it can generate captions or provide a description of what the image depicts. It will also handle text-to-speech requests. And users will now be able to upload documents directly and ask the service to analyze them — a capability that other chatbots like Anthropic’s Claude have included for months.

For developers, using the newest model will effectively be three times cheaper. OpenAI said that it was slashing costs for input and output tokens — a unit used by large language models to understand instructions and respond with answers.

In addition to announcing its newest large language model, OpenAI revealed that ChatGPT now has more than 100 million weekly active users around the world and is used by more than 92 percent of Fortune 500 companies. The company also said that it would defend customers, including enterprises, not only against legal claims around copyright infringement that might arise as a result of using its products, but it would also pay for costs incurred as a result.

OpenAI also revealed single-application "mini-ChatGPTs" today, small tools that are focused on a single task that can be built without even knowing how to code. GPTs created by the community can be immediately shared, and OpenAI will open a "store" where verified builders can make their creation available to anyone. 

The company didn’t announce when GPT-4 Turbo would come out of preview and be available more generally. Accessing GPT-4 currently costs $20 a month.

YouTube’s crackdown on ad blockers is hurting the companies who make them. Multiple ad blocking companies say that thousands of people are uninstalling their products after YouTube started showing warnings to people trying to watch videos on its website with ad blockers enabled.

One of the companies, AdGuard, told Wired that more than 11,000 people have uninstalled its Chrome extension each day since October 9, compared to 6,000 uninstallations per day before YouTube implemented the change. On October 18, 52,000 people uninstalled AdGuard, the company’s CTO Andrey Meshkov told Wired. However, installations of AdGuard’s paid version, which YouTube’s crackdown doesn’t affect, went up.

Another ad blocking company, Ghostery, said that its usage was flat in October as it experienced three to five times the daily number of installs as well as uninstalls. Notably, the company said that more than 90 percent of its users who completed a survey about why they uninstalled the product said they did so because the tool no longer worked with YouTube.

Since YouTube’s crackdown only seems to affect people who access its website through Chrome on laptops and desktops, some users also tried to use other browsers as a workaround. Ghostery told Wired that its installations of Microsoft’s Edge browser went up by 30 percent in October compared to September.

YouTube ads are increasingly contributing more to Google’s overall revenue. The company sold more than $22 billion in ads on the platform from the beginning of this year through September. But the streaming platform is also trying to push more people to pay for YouTube Premium, which gets rid of ads, lets people download videos, stream videos in higher quality and access YouTube Music. Earlier this year, the company bumped up YouTube Premium’s pricing by $2 to $14 a month.
