The 2024 Index is our most comprehensive to date and arrives at an important moment when AI's influence on society has never been more pronounced. This year, we have broadened our scope to more extensively cover essential trends such as technical advancements in AI, public perceptions of the technology, and the geopolitical dynamics surrounding its development. Featuring more original data than ever before, this edition introduces new estimates on AI training costs, detailed analyses of the responsible AI landscape, and an entirely new chapter dedicated to AI's impact on science and medicine. The AI Index report tracks, collates, distills, and visualizes data related to artificial intelligence (AI). Our mission is to provide unbiased, rigorously vetted, broadly sourced data in order for policymakers, researchers, executives, journalists, and the general public to develop a more thorough and nuanced understanding of the complex field of AI. The AI Index is recognized globally as one of the most credible and authoritative sources for data and insights on artificial intelligence. Previous editions have been cited in major newspapers, including the The New York Times, Bloomberg, and The Guardian, have amassed hundreds of academic citations, and been referenced by high-level policymakers in the United States, the United Kingdom, and the European Union, among other places. This year's edition surpasses all previous ones in size, scale, and scope, reflecting the growing significance that AI is coming to hold in all of our lives.

ChatGPT developer OpenAI has signed a deal to bring news content from the Wall Street Journal, New York Post, the Times and the Sunday Times to the artificial intelligence platform, the companies said on Wednesday. Neither party disclosed a dollar figure for the deal. The deal will give OpenAI access to current and archived content from all of News Corp's publications. The deal comes weeks after the AI heavyweight signed a deal with the Financial Times to license its content for the development of AI models. Other publications, including the New York Times, have taken a different tack: suing OpenAI and Microsoft, the startup's key backer, over the use of its content to train generative AI and large-language model systems.

Scarlett Johansson said Monday that she was "shocked, angered and in disbelief" when she heard that OpenAI used a voice "eerily similar" to hers for its new ChatGPT 4.0 chatbot, even after she had declined to provide her voice. Earlier on Monday, OpenAI announced on X that it would pause the AI voice, known as "Sky," while it addresses "questions about how we chose the voices in ChatGPT." The company said in a blog post that the "Sky" voice was "not an imitation" of Johansson's voice, but that it was recorded by a different professional actor, whose identity the company would not reveal to protect her privacy. But Johansson said in a statement to NPR on Monday that OpenAI's Chief Executive Officer Sam Altman had asked her in September to voice the ChatGPT 4.0 system because he thought her "voice would be comforting to people." She declined, but nine months later, her friends, family and the public noticed how the "Sky" voice resembled hers.

Last spring, the clothing brand Levi Strauss & Co. announced plans to introduce "customized AI-generated models" into its online shopping platforms. These "body-inclusive avatars" would come in a range of sizes, ages, and skin tones and would help Levi's create a more "diverse" lineup in a way the company considered "sustainable." A lot of (real) people were appalled. Why not give those jobs to actual humans of the sizes, ages, and skin tones Levi's sought? Was "sustainable" just PR-speak for "cheaper"?

Reddit Inc. forged a partnership with OpenAI that will bring its content to the chatbot ChatGPT and other products, while also helping the social media company add new artificial intelligence features to its forums. Shares of Reddit, which had their initial public offering in March, jumped as much as 15% in late trading following the announcement. The agreement "will enable OpenAI's AI tools to better understand and showcase Reddit content, especially on recent topics," the companies said Thursday in a joint statement. The deal allows OpenAI to display Reddit's content and train AI systems on its partner's data. Reddit will also offer its users new AI-based tools built on models created by OpenAI, which will place ads on its partner's site.

At the end of I/O, Google's annual developer conference at the Shoreline Amphitheater in Mountain View, Google CEO Sundar Pichai revealed that the company had said "AI" 121 times. That, essentially, was the crux of Google's two-hour keynote -- stuffing AI into every Google app and service used by more than two billion people around the world. Here are all the major updates from Google's big event, along with some additional announcements that came after the keynote. Google announced a brand new AI model called Gemini 1.5 Flash, which it says is optimised for speed and efficiency. Flash sits between Gemini 1.5 Pro and Gemini 1.5 Nano, which its the company's smallest model that runs locally on device.

TikTok is ramping up its efforts to automatically label AI-generated content in its app, even when it was created with third-party tools. The company announced plans to support content credentials, a kind of digital watermark that indicates the use of generative AI. TikTok's rules already require creators to disclose "realistic" AI-generated content. But that policy can be difficult for the company to enforce, particularly when creators use other companies' AI tools. But because content credentials are increasingly used across the AI industry, TikTok's new automated labels should be able to address some of those gaps. Often described as a "nutrition label for digital content," content credentials attach "tamper-evident metadata" that can trace the origins of an image and AI tools that were used to edit it along the way.

Elon Musk's Neuralink has shared a progress update about the first person to receive a brain chip that allows him to operate a computer and play video games with his mind. The company announced that it has been more than 100 days since Noland Arbaugh had the device implanted in his brain - and the 29-year-old is still doing. Arbaugh suffered a life-changing driving accident whilst working as a camp counselor in 2016, which left him with'absolutely no feeling' from the shoulders down. His life changed again on January 27 when he underwent a 30-minute procedure that used a'sewing machine-like' robot to remove a small chunk of his skull and stitch the chip into his brain. However, Neuralink revealed that some of the threads connected to the chip had retracted weeks after the surgery, resulting in a decrease in the number of effective nodes - but modified the algorithm to boost signal translations.

Profits at Microsoft beat Wall Street's expectations as its heavy bet on artificial intelligence continued to bear fruit in the second quarter. The technology giant has invested billions of dollars into AI in a bid to turbocharge its growth, particularly of its cloud computing services. Its cloud computing revenue surged by more than 20% in the latest quarter. Microsoft's AI tools "are orchestrating a new era of AI transformation, driving better business outcomes across every role and industry," said Satya Nadella, the chief executive of Microsoft. As the group races to integrate AI across its software and services, Nadella said its Azure cloud computing business saw the pace of deals worth 100m and 10m increase by double-digit percentages.

Nearly a year after adding generative AI-powered editing capabilities to Photoshop, Adobe is souping up its flagship product with even more AI. On Tuesday, the company announced that Photoshop is getting the ability to generate images with simple text prompts directly within the app. There are also new features to let the AI draw inspiration from reference images to create new ones and generate backgrounds more easily. The tools will make using Photoshop easier for both professionals as well as casual enthusiasts who may have found the app's learning curve to be steep, Adobe thinks. "A big, blank canvas can sometimes be the biggest barrier," Erin Boyce, Photoshop's senior marketing director, told Engadget in an interview. "This really speeds up time to creation.
