Even OpenAI has given up trying to detect ChatGPT plagiarism

OpenAI, the creator of the wildly popular artificial intelligence (AI) chatbot ChatGPT, has shut down the tool it developed to detect content created by AI rather than humans. The tool, dubbed AI Classifier, has been shuttered just six months after it was launched due to its “low rate of accuracy,” OpenAI said.

Since ChatGPT and rival services have skyrocketed in popularity, there has been a concerted pushback from various groups concerned about the consequences of unchecked AI usage. For one thing, educators have been particularly troubled by the potential for students to use ChatGPT to write their essays and assignments, then pass them off as their own.

OpenAI’s AI Classifier was an attempt to allay the fears of these and other groups. The idea was it could determine whether a piece of text was written by a human or an AI chatbot, giving people a tool to both assess students fairly and combat disinformation.

Yet even from the start, OpenAI did not seem to have much confidence in its tool. In a blog post announcing the tool, OpenAI declared that “Our classifier is not fully reliable,” noting that it correctly identified AI-written texts from a “challenge set” just 26% of the time.

The decision to drop the tool was not given much fanfare, and OpenAI has not posted a dedicated post on its website. Instead, the company has updated the post which revealed the AI Classifier, stating that “the AI classifier is no longer available due to its low rate of accuracy.”

The update continued: “We are working to incorporate feedback and are currently researching more effective provenance techniques for text, and have made a commitment to develop and deploy mechanisms that enable users to understand if audio or visual content is AI-generated.”

Better tools are needed

The AI Classifier is not the only tool that has been developed to detect AI-crafted content, as rivals like GPTZero exist and will continue to operate, despite OpenAI’s decision.

Past attempts to identify AI writing have backfired spectacularly. For instance, in May 2023, a professor mistakenly flunked their entire class after enlisting ChatGPT to detect plagiarism in their students’ papers. Needless to say, ChatGPT got it badly wrong, and so did the professor.

It’s cause for concern when even OpenAI admits it can’t properly perceive plagiarism created by its own chatbot. It comes at a time of increasing anxiety about the destructive potential of AI chatbots and calls for a temporary suspension of development in this field. If AI has as much of an impact as some people are predicting, the world is going to need stronger tools than OpenAI’s failed AI Classifier.

ChatGPT o1 vs. o3 vs. 4o: Which should you use?
ChatGPT on a laptop

We're now into the third year of the AI boom, and industry leaders are showing no signs of slowing down, pushing out newer and (presumably) more capable models on a regular basis. ChatGPT, of course, remains the undisputed leader.

But with more than a half-dozen models available from OpenAI alone, figuring out which one to use for your specific project can be a daunting task.

ChatGPT vs. Perplexity: battle of the AI search engines
Perplexity on Nothing Phone 2a.

The days of Google's undisputed internet search dominance may be coming to an end. The rise of generative AI has ushered in a new means of finding information on the web, with ChatGPT and Perplexity AI leading the way.

Unlike traditional Google searches, these platforms scour the internet for information regarding your query, then synthesize an answer using a conversational tone rather than returning a list of websites where the information can be found. This approach has proven popular with users, even though it's raised some serious concerns with the content creators that these platforms scrape for their data. But which is best for you to actually use? Let's dig into how these two AI tools differ, and which will be the most helpful for your prompts.
Pricing and tiers
Perplexity is available at two price points: free and Pro. The free tier is available to everybody and offers unlimited "Quick" searches, 3 "Pro" searches per day, and access to the standard Perplexity AI model. The Pro plan, which costs $20/month, grants you unlimited Quick searches, 300 Pro searches per day, your choice of AI model (GPT-4o, Claude-3, or LLama 3.1), the ability to upload and analyze unlimited files as well as visualize answers using Playground AI, DALL-E, and SDXL.

​​OpenAI spills tea on Musk as Meta seeks block on for-profit dreams

OpenAI has been on a “Shipmas” product launch spree, launching its highly-awaited Sora video generator and onboarding millions of Apple ecosystem members with the Siri-ChatGPT integration. The company has also expanded its subscription portfolio as it races toward a for-profit status, which is reportedly a hot topic of debate internally.

Not everyone is happy with the AI behemoth abandoning its nonprofit roots, including one of its founding fathers and now rival, Elon Musk. The xAI chief filed a lawsuit against OpenAI earlier this year and has also been consistently taking potshots at the company.
