OpenAI, the research laboratory behind AI program ChatGPT, has released a tool designed to detect whether text has been written by artificial intelligence, but warns it's not completely reliable – yet. In a blog post on Tuesday, OpenAI linked to a new classifier tool that has been trained to distinguish between text written by a human and that written by a variety of AI, not just ChatGPT. Open AI researchers said that while it was "impossible to reliably detect all AI-written text", good classifiers could pick up signs that text was written by AI. The tool could be useful in cases where AI was used for "academic dishonesty" and when AI chatbots were positioned as humans, they said. But they admited the classifier "is not fully reliable" and only correctly identified 26% of AI-written English texts.

Ray, the popular open-source machine learning (ML) framework, has released its 2.2 version with improved performance and observability capabilities, as well as features that can help to enable reproducibility. The Ray technology is widely used by organizations to scale ML models across clusters of hardware, for both training and inference. Among Ray's many users is generative AI pioneer OpenAI, which uses Ray to scale and enable a variety of workloads, including supporting ChatGPT. The lead commercial sponsor behind the Ray open-source technology is San Francisco-based Anyscale, which has raised $259 million in funding to date.

OpenAI said Tuesday that it has released an AI "classifier" for identifying AI-authored text written by AI like its own ChatGPT. The problem? ChatGPT is pretty good at evading OpenAI's new tool. ChatGPT has absolutely overwhelmed academia, where students are using it as a virtual assistant of sorts in a variety of tasks. Unfortunately, some students are crossing the line and using it to create content that they are passing off as original--cheating, in other words. The trouble is trying to determine which answers were written by a human, and which by an AI.

In MIT Technology Review's 2023 list of 10 Breakthrough Technologies, our editors featured image-making AI, the technology from OpenAI that is producing some truly amazing images from simple prompts. How it is expected to evolve over the next several years? We are launching a limited series of research reports that dive deep into the business applications of generative AI. The first of these reports - focused on industrial design and engineering - is available for purchase now, here: https://lnkd.in/dHdVMQ3i

The tool, which is available at no charge, is itself based on an AI model. It can detect text generated by not only OpenAI's neural networks but also competing software from other companies. However, the startup cautioned that the tool currently has a number of significant accuracy limitations.

Two months after OpenAI unnerved some educators with the public release of ChatGPT, an AI chatbot that can help students and professionals generate shockingly convincing essays, the company is unveiling a new tool to help teachers adapt. OpenAI on Tuesday announced a new feature, called an "AI text classifier," that allows users to check if an essay was written by a human or AI. The tool, which works on English AI-generated text, is powered by a machine learning system that takes an input and assigns it to several categories. In this case, after pasting a body of text such as a school essay into the new tool, it will give one of five possible outcomes, ranging from "likely generated by AI" to "very unlikely." Lama Ahmad, policy research director at OpenAI, told CNN that educators have been asking for a ChatGPT feature like this, but warns it should be "taken with a grain of salt."

I also got an "unclear" result for some articles written by CNET Money, with others getting an "unlikely" classification. The outlet says these articles were "assisted by an AI engine and reviewed, fact-checked and edited by our editorial staff," so there are likely some human tweaks in there (especially since CNET has added corrections to over half of them). While CNET's owner hasn't said which specific system it's using for the articles, my co-worker Mia Sato has reported that it's used a tool called Wordsmith for some of its content. OpenAI says its tool isn't just for GPT, though, and that it should detect "text written by AIs from a variety of providers."

OpenAI has released a tool to help you determine whether text was more likely written by a human or AI. However, the ChatGPT maker warns that its equivalent of Blade Runner's Voight-Kampff test can also get it wrong. The tool includes a box where you can paste text that's at least 1,000 characters long. It will then spit out a verdict, like "The classifier considers the text to be very unlikely AI-generated" or "The classifier considers the text to be possibly AI-generated." I tested it by prompting ChatGPT to write an essay about the migratory patterns of birds, which the detection tool then described as "possibly AI-generated."

The end of 2022 came on the heels of AI technologies experiencing widespread adoption due to the stunning popularity of OpenAI and ChatGPT. For the first time, AI achieved mass-market appeal by proving its utility and value in creating successful business outcomes. Many AI technologies that seem like a revolution to everyday people in 2023 have actually been in active use by big businesses and media for several years. Join me as I take a closer look at the technology powering these solutions, in particular, generative AI systems for voice cloning, its business benefits, and ethical approaches to using AI. In short, voice cloning enables one person to speak using the voice of another person.

OpenAI, the creator of the language tool ChatGPT and image generator Dall-E, could be facing some new, three-dimensional competition on the blockchain. In an introductory video, the brand says users will be able to type in text to generate responsive characters with "unique personalities, identities, traits, voices, and bodies." Users can mint the NFTs at mycharacter.ai. It remains to be seen whether CharacterGPT will gain the popularity of either ChatGPT or OpenAI's bot-powered Dall-E, which attracts 1.5 million users a day. The CharacterGPT blockchain product looks poised to more directly compete with Dall-E rather than ChatGPT, which generates text responses to typed questions. It has created massive interest through its ability to write convincing articles, cover letters, emails, and messages on dating apps.
