ChatGPT has a new way to detect its own plagiarism

OpenAI announced on Tuesday a new tool called AI Text Classifier, which is intended to distinguish between AI-generated text and words that were written by a human.

The brand’s latest tool comes after criticism of its ChatGPT text generator. While it has been popular since its November 2022 release, the chatbot has been embroiled in plagiarism concerns, with the tool already being banned from schools. However, reports have also surfaced of students using ChatGPT to create essays for take-home assignments.

Making the AI Text Classifier available is OpenAI’s effort to keep its brand honest. OpenAI said in a blog post that it would like feedback from parents and teachers on the quality of its plagiarism-detection tool. However, it does note that the Classifier has some limitations at the moment, including not working well for texts shorter than 1,000 words, not working well for languages other than English, being easily duped if AI text is edited, and producing false positives, where the tool incorrectly identifies a human-written text as AI, among others.

OpenAI added that the Classifier has an approximate 26% rate of correctly identifying an AI text as likely AI-written (true positives),and a 9% instance of incorrectly identifying a human text as AI-written (false positives).

When testing the AI Text Classifier, I compared the ChatGPT prompt “write a 1,000-word essay on the number of stars in the sky” to the text from my article “The 6 biggest problems with ChatGPT right now.”

Logging into the Classifier is easy if you already have an OpenAI account and servers are not congested. You just paste your text into the text box and select submit. The result will display below. The tool accurately identified the text from my article as human-written and the ChatGPT-written text as AI-written.

There are a number of other plagiarism-detection tools already available, with varying degrees of accuracy. GPT-2 Output Detector is another tool developed by OpenAI. Others include Writer AI, Content at Scale, GPTZero, and Giant Language Model Test Room (GLTR). We tested these tools and similarly found varying degrees of accuracy between the identification of ChatGPT text and human text.

It’s not clear how the AI Text Classifier will be implemented moving forward, but ChatGPT is already solidifying itself in several industries, from journalism to business and technology. With all the proper tools in place, it likely just becomes a matter of ethics.

Meta’s new AI app lets you share your favorite prompts with friends

Meta has been playing the AI game for a while now, but unlike ChatGPT, its models are usually integrated into existing platforms rather than standalone apps. That trend ends today -- the company has launched the Meta AI app and it appears to do everything ChatGPT does and more.

Powered by the latest Llama 4 model, the app is designed to "get to know you" using the conversations you have and information from your public Meta profiles. It's designed to work primarily with voice, and Meta says it has improved responses to feel more personal and conversational. There's experimental voice tech included too, which you can toggle on and off to test -- the difference is that apparently, full-duplex speech technology generates audio directly, rather than reading written responses.

It’s not your imagination — ChatGPT models actually do hallucinate more now
Deep Research option for ChatGPT.

OpenAI released a paper last week detailing various internal tests and findings about its o3 and o4-mini models. The main differences between these newer models and the first versions of ChatGPT we saw in 2023 are their advanced reasoning and multimodal capabilities. o3 and o4-mini can generate images, search the web, automate tasks, remember old conversations, and solve complex problems. However, it seems these improvements have also brought unexpected side effects.

What do the tests say?

ChatGPT’s awesome Deep Research gets a light version and goes free for all
Deep Research option for ChatGPT.

There’s a lot of AI hype floating around, and it seems every brand wants to cram it into their products. But there are a few remarkably useful tools, as well, though they are pretty expensive. ChatGPT’s Deep Research is one such feature, and it seems OpenAI is finally feeling a bit generous about it. 

The company has created a lightweight version of Deep Research that is powered by its new o4-mini language model. OpenAI says this variant is “more cost-efficient while preserving high quality.” More importantly, it is available to use for free without any subscription caveat.
