NEW YORK--(BUSINESS WIRE)--Apr 8, 2025--
Pangram, the most accurate and most reliable tool for detecting text created by AI, has released a new, better detection model. The upgrade improves on Pangram’s already unmatched accuracy and includes a unique feature that will aid educators when assessing student-submitted writing.

The new model, already released to customers as part of regular updates and improvements, has been re-engineered and retrained, and is proving even more accurate and successful in identifying AI-generated text from the newest models of AI providers such as OpenAI, Anthropic, and Gemini. Pangram’s new model is also, it seems, able to detect AI-created text from models that are awaiting public release.
“Our detection technology was already the best because we built it differently,” said Max Spero, Pangram’s CEO. “Pangram does not rely on perplexity and burstiness like other AI classifiers. Pangram is trained using ‘synthetic mirrors’ of the hardest documents to classify and then it is retrained over and over again. That makes it adaptable to new models and doesn’t require significant re-engineering or time-intensive retraining to remain relevant.”
The new detection capabilities also are successful at detecting “humanized” text – text that has been put through an automated paraphrasing engine. Humanizing text is a common tactic used by students and others who may wish to hide or contaminate the origins of text. Several humanizing products explicitly advertise their ability to beat AI detection. Although, in internal testing, even these humanizers fail to bypass Pangram.
“The days of being able to ask ChatGPT to do your assignments, then wash it with Grammarly or QuillBot, and expecting to get away with it – those days are coming to an end. If they’re not already over,” said Spero. “With Pangram, teachers are going to spot the use of humanizers with precision and regularity,” he said.
In addition to the significant upgrades, Pangram has released a new feature that will assist educators in identifying text created by AI, and, more importantly, in making sound decisions about how to address it. Starting immediately in educator dashboards, Pangram results will now return a result of “mixed” for submitted text, in addition to the classifications of “human” or “AI.”
This “mixed” designation will be applied to text that is likely to be partly human composed, mixed with portions that are likely produced by AI. Further, the “mixed” designation will break down the percentages of each – human versus the percentage that is detected as AI. Finally, in a “mixed” result, educators will be able to see the specific segment of the text in each category – human or AI.
Insight into mixed text is important because many AI users, especially students, generate AI answers or solutions but then edit the results themselves, hoping to either fool an AI detector or add some of their own voice, or both.
“Being able to see a breakdown, seventy-thirty, or ninety-ten, will help teachers make better decisions about what they expected from their students and then determine the actions, if any, that might be necessary,” Spero said. “More information for teachers is better, more insight is better. We’re able to do that with Pangram.”
Spero and cofounder Bradley Emi have master’s degrees in computer science from Stanford University, where they met as undergraduates. Before founding Pangram, Spero was an AI engineer at Google, while Emi was a machine learning engineer at Tesla.

Uvira, CONGO (AP) — A climate of fear reigned Saturday in Uvira, a strategic city in eastern Congo, days after it fell to the Rwanda -backed M23 group, as fighting in the region escalated despite a U.S. mediated peace deal.
The Associated Press gained rare access to the city, which was the Congo government’s last major foothold in South Kivu province after the provincial capital of Bukavu fell to the rebels in February. Its capture allows the rebels to consolidate a broad corridor of influence across the east.
M23 said it took control of Uvira earlier this week, following a rapid offensive launched at the start of the month. Along with the more than 400 people killed, about 200,000 have been displaced, regional officials say.
On Saturday, the situation in Uvira still had not returned to normal. There was absolute silence and no traffic, apart from military jeeps circulating on the empty streets. The banks were closed and people have not resumed their jobs — only a few dared to go out during the day, and no one ventured outside after sunset, with armed M23 fighters patrolling the city.
“Some people left the city, but we stayed," Maria Esther, a 45-year-old mother of 10, told AP. “But the situation hasn’t returned to normal, we haven’t resumed our usual activities because there’s no money circulating.”
Joli Bulambo, another resident of Uvira, said: “People thought that the situation that had happened in Goma with the deaths would be the same here in Uvira, but fortunately, there were not many deaths because God helped."
The rebels’ latest offensive comes despite a U.S.-mediated peace agreement signed last week by the Congolese and Rwandan presidents in Washington.
The United States accused Rwanda of violating the agreement by backing a deadly new rebel offensive in the mineral-rich eastern Congo, and warned that the Trump administration will take action against “spoilers” of the deal.
The accord didn’t include the rebel group, which is negotiating separately with Congo and agreed earlier this year to a ceasefire that both sides accuse the other of violating. However, it obliges Rwanda to halt support for armed groups like M23 and work to end hostilities.
Marco Rubio, U.S. Secretary of State, said on X on Saturday: “Rwanda’s actions in eastern DRC are a clear violation of the Washington Accords signed by President Trump, and the United States will take action to ensure promises made to the President are kept.”
There was no immediate reaction from Rwanda.
The rebels’ advance pushed the conflict to the doorstep of neighboring Burundi, which has maintained troops in eastern Congo for years, heightening fears of a broader regional spillover.
More than 100 armed groups are vying for a foothold in mineral-rich eastern Congo, near the border with Rwanda, most prominently M23. The conflict has created one of the world’s most significant humanitarian crises, with more than 7 million people displaced, according to the U.N. agency for refugees.
Local U.N. partners report that more than 200,000 people have been displaced across the province since Dec. 2. Civilians also have crossed into Burundi, and there have been reports of shells falling in the town of Rugombo, on the Burundian side of the border, raising concerns about the conflict spilling over into Burundian territory.
Congo, the U.S. and U.N. experts accuse Rwanda of backing M23, which has grown from hundreds of members in 2021 to around 6,500 fighters, according to the U.N.
Congo’s Foreign Minister Thérèse Kayikwamba Wagner on Friday accused Rwanda of trampling on the peace agreement, which she described as bringing “hope of a historic turning point.”
She warned, however, that the “entire process … is at stake,” and urged the Security Council to impose sanctions against military and political leaders responsible for the attacks, ban mineral exports from Rwanda and prohibit it from contributing troops to U.N. peacekeeping missions.
“Rwanda continues to benefit, especially financially but also in terms of reputation, from its status as a troop-contributing country to peacekeeping missions,” Wagner told AP.
Bertrand Bisimwa, deputy coordinator of the AFC/M23 rebel movement told AP in an exclusive interview Friday that peace commitments have remained largely theoretical. “Regardless of the ceasefire agreements we sign and the mutual commitments we make, nothing is implemented on the ground,” he said.
Asked about the expansion of M23 operations toward the Uvira region, Bisimwa said the region was a long-standing hot spot of ethnic tensions and violence. “For a long time, people were attacked and killed because of their community affiliation,” he said.
On Friday, Rwanda’s Foreign Minister Olivier Nduhungirehe told diplomats that Congo had declared it would continue fighting in M23 recaptured territories and it was only after M23 retaliated that the international community “suddenly woke up.”
“The DRC has openly declared that it would not observe any ceasefire and would instead continue fighting to recapture territories held by the AFC/M23, even as the peace process unfolded," he said.
While Rwanda denies the claim that it backs M23, it acknowledged last year that it has troops and missile systems in eastern Congo, allegedly to safeguard its security. U.N. experts estimate there are up to 4,000 Rwandan forces in Congo.
