OpenAI releases “not fully reliable” tool to detect AI generated content

ChatGPT has been creating waves across the internet with its writing ability and responses to requests. The use of ChatGPT has been full of     1     . There have been concerns that students can use this tool to     2     AI-generated work and claim it as their own.

OpenAI, the research laboratory behind ChatGPT, has released a tool designed to     3     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     4     tool that has been trained to distinguish between text written by a human and that written by a variety of AI, not just ChatGPT.

The tool could be useful in cases where AI was used for “    5     dishonesty” and when AI chatbots were positioned as humans, they said. But they admitted the tool “is not fully reliable” and only correctly identified 26% of AI-written English texts. It also incorrectly     6     human-written texts as probably written by AI tools 9% of the time.

“Our classifier’s reliability     7     improves as the length of the input text increases. Compared to our     8     released classifier, this new classifier is significantly more reliable on text from more recent AI systems.”

Since ChatGPT was opened up to public    9    , it has given rise to a wave of concern among educational institutions across the world that it could lead to cheating in exams or assessments. Lecturers in the UK are being urged to review the way in which their courses were     10    , while some universities have banned the technology entirely and returned to pen-and-paper exams to stop students using AI.

A New Exoplanet in the System

In 2014, data from NASA’s Kepler Space Telescope allowed astronomers to announce the detection of three planets orbiting Kepler-138. This was based on a     1    dip in starlight as the planet momentarily passed in front of their star, a transit.

Benneke and his colleague Diana Dragomir, from the University of New Mexico, came up with the idea of re-observing the planetary     2    with the Hubble and Spitzer space telescopes between 2014 and 2016 to catch more transits of Kepler-138d, the third planet in the system, in order to study its atmosphere.

While earlier NASA Kepler space telescope observations only showed transits of three small planets around Kepler-138, Piaulet and her team were     3    to find that the Hubble and Spitzer observations suggested the presence of a fourth planet in the system, Kepler-138e.

This newly found planet is small and farther from its star than the three others, taking 38 days to complete an orbit.The planet is in the     4    zone of its star, a temperate region where a planet receives just the right amount of heat from its cool star to be neither too hot nor too cold to allow the presence of liquid water. Observing the exoplanet’s transit would have allowed astronomers to     5    its size.

With Kepler-138e, the masses of the    6    known planets were measured again via the transit timing-variation method, which consists of     7    small variations in the precise moments of the planets’ transits in front of their star caused by the gravitational pull of other nearby planets.

The researchers had another surprise: they found that the two water worlds Kepler-138c and d are twin planets, with     8    the same size and mass, while they were previously thought to be greatly different. The closer-in planet,Kepler-138b, on the other hand, is     9     to be a small Mars-mass planet, one of the smallest exoplanets known to date.

“As our instruments and techniques become     10     enough to find and study planets that are farther from their stars, we might start finding a lot more water worlds like Kepler-138 c and d,” Benneke concluded.
