A college student made an app to detect AI-written text : NPR

Teachers worried about students turning in essays written by a popular artificial intelligence chatbot now have a new tool of their own.

Edward Tian, a 22-year-old senior at Princeton University, has built an app to detect whether text is written by ChatGPT, the viral chatbot that’s sparked fears over its potential for unethical uses in academia.

Tian, a computer science major who is minoring in journalism, spent part of his winter break creating GPTZero, which he said can “quickly and efficiently” decipher whether a human or ChatGPT authored an essay.

His motivation to create the bot was to fight what he sees as an increase in AI plagiarism. Since the release of ChatGPT in late November, there have been reports of students using the breakthrough language model to pass off AI-written assignments as their own.

“there’s so much chatgpt hype going around. is this and that written by AI? we as humans deserve to know!” Tian wrote in a tweet introducing GPTZero.

Tian said many teachers have reached out to him after he released his bot online on Jan. 2, telling him about the positive results they’ve seen from testing it.

More than 30,000 people had tried out GPTZero within a week of its launch. It was so popular that the app crashed. Streamlit, the free platform that hosts GPTZero, has since stepped in to support Tian with more memory and resources to handle the web traffic.

How GPTZero works

To determine whether an excerpt is written by a bot, GPTZero uses two indicators: “perplexity” and “burstiness.” Perplexity measures the complexity of text; if GPTZero is perplexed by the text, then it has a high complexity and it’s more likely to be human-written. However, if the text is more familiar to the bot — because it’s been trained on such data — then it will have low complexity and therefore is more likely to be AI-generated.

Separately, burstiness compares the variations of sentences. Humans tend to write with greater burstiness, for example, with some longer or complex sentences alongside shorter ones. AI sentences tend to be more uniform.

In a demonstration video, Tian compared the app’s analysis of a story in The New Yorker and a LinkedIn post written by ChatGPT. It successfully distinguished writing by a human versus AI.

Tian acknowledged that his bot isn’t foolproof, as some users have reported when putting it to the test. He said he’s still working to improve the model’s accuracy.

But by designing an app that sheds some light on what separates human from AI, the tool helps work toward a core mission for Tian: bringing transparency to AI.

“For so long, AI has been a black box where we really don’t know what’s going on inside,” he said. “And with GPTZero, I wanted to start pushing back and fighting against that.”

The quest to curb AI plagiarism

The college senior isn’t alone in the race to rein in AI plagiarism and forgery. OpenAI, the developer of ChatGPT, has signaled a commitment to preventing AI plagiarism and other nefarious applications. Last month, Scott Aaronson, a researcher currently focusing on AI safety at OpenAI, revealed that the company has been working on a way to “watermark” GPT-generated text with an “unnoticeable secret signal” to identify its source.

The open-source AI community Hugging Face has put out a tool to detect whether text was created by GPT-2, an earlier version of the AI model used to make ChatGPT. A philosophy professor in South Carolina who happened to know about the tool said he used it to catch a student submitting AI-written work.

The New York City education department said on Thursday that it’s blocking access to ChatGPT on school networks and devices over concerns about its “negative impacts on student learning, and concerns regarding the safety and accuracy of content.”

Tian is not opposed to the use of AI tools like ChatGPT.

GPTZero is “not meant to be a tool to stop these technologies from being used,” he said. “But with any new technologies, we need to be able to adopt it responsibly and we need to have safeguards.”

What Is GameFi? How Can You Earn Money Playing Video Games?

DeFi became the hottest new trend in 2020. On the other hand, revenue from the billion-dollar gaming industry continues to grow annually—it is estimated that by the end of 2021, the global video gaming market will be worth over $178 billion.

So, what happens if you fuse two wildly successful industries? A community of gaming and blockchain enthusiasts has already merged DeFi with gaming, and since the pandemic, its popularity has only gone up.

The industry is called “GameFi.” So, how does GameFi work, and can you really earn money playing video games?

What is Tiny10 (Lightweight Windows 10) and How to Install It | Beebom

how to install tiny10

We love the fact that Windows 11 is feature-rich and visually modern, although there are some UI inconsistencies that Rectify11 has fixed to a large extent. Apart from that, Microsoft has been adding several new features to its desktop OS since Windows 10 days. Fast forward, and both Windows 10 and 11 are bloated with new features, unnecessary apps, and redundant background services. To be frank, Windows 10/11 feels quite heavy compared to Windows 7. And now, to trim down Windows 10 to its bare essentials, a developer has released Tiny10, which is a lightweight version of Windows 10. It takes much less space, works even on low RAM computers, and comes with no bloatware. To find out what is Tiny10 and how to install it, keep on reading.

Parler Doxxes VIP Members Announcing Kanye West Acquisition

Parler, the rightwing knockoff of Twitter that’s not Truth Social, accidentally exposed the personal email addresses of some of its most elite members on Monday. Rushing to tell them about the company’s acquisition agreement with the artist formerly known as Kanye West, top brass sent out an email that CC-ed a group of VIP members rather than blind carbon copying them. The result was that droves of partisan ghouls like Tim Pool and Laura Loomer had their email addresses shared with one another.
