OpenAI’s rocky GPT-5 launch is the beginning of an uphill battle for AI, as Meta announces another restructuring

Published

The launch of GPT-5 was meant to herald a new era for OpenAI. After introducing GPT-4 two years prior, the company was finally going to move forward from iterative releases based on GPT-4, and unleash a benchmark-topping next-generation model. There was only one problem. Users didn’t like it.

While OpenAI CEO Sam Altman hoped for a necessary iterative step toward the goal of Artificial General Intelligence (AGI), user feedback claimed that the new model lacked elements that made its previous models so popular. Soon after, OpenAI brought back older models for users willing to pay for them.

AI models are becoming more difficult to develop

GPT-5 was supposed to be as game-changing as GPT-4, if not more so. But it wasn’t anything close to that. This raises the question: Is the AI industry reaching a plateau? The teams behind AI model development can’t feed more data into their models to improve their capabilities anymore. Now, it’s about tweaking or trying something new, and it doesn’t feel like any of the big AI players have quite figured out what that is yet.

Altman accused Meta of offering huge, hundred-million-dollar signing bonuses to some of its staff earlier this year. As a result, several high-profile OpenAI staff members have been successfully poached by Meta, including lead OpenAI engineer Shengjia Zhao.

Despite Meta’s push for AI talent, the team is undergoing restructuring, with staff being reportedly split across several divisions, with recruitment frozen for an undetermined amount of time. That may give OpenAI a window to pick up any new hot AI talent, without Meta throwing the big checks around.

One thing is clear: the path that large AI businesses are undertaking to race toward AGI is taking its toll. As many AI models now pivot toward Agentic AI and Thinking models, the cost to compute each query will inevitably get higher, as more complex tasks require more tokens. More tokens mean higher computational costs, which makes running AI businesses more expensive.

Despite these recent headwinds, the AI train shows few signs of stopping, but new data shows the technology isn’t making money for the organizations that are using it.

a report from MIT suggested that as few as 5% of organizations saw an impact on P&L after adopting AI tools. As a result, AI-adjacent tech stocks fell, as faith in the profitability of AI was shaken, stoking fears of an AI bubble. OpenAI has yet to turn a profit, despite its annual recurring revenue predicted to hit $20 billion this year. But CEO Sam Altman is happy to run the company at a loss and prioritize growth, he told CNBC. This suggests that OpenAI hasn’t found the killer app for AI, which would prove that the new technology could indeed be profitable. Whether or not that killer app ends up being AGI remains to be seen.

Altman himself has acknowledged that the AI industry may be a bubble, though he stopped short of suggesting OpenAI was a part of that assessment, hinting that there was still a viable business within it. During a dinner shared with reporters (via The Verge), Altman said:

“If you look at most of the bubbles in history, like the tech bubble, there was a real thing. Tech was really important. The internet was a really big deal. People got overexcited. Are we in a phase where investors as a whole are overexcited about AI? My opinion is yes. Is AI the most important thing to happen in a very long time? My opinion is also yes.”

Nvidia has benefited from the AI gold rush, and could stand to rake in even more as it sells the notion of “AI factories” to investors. And the company’s plans for AI infrastructure span decades, signaling that Nvidia sees value in AI for the long haul.

Since OpenAI is as reliant on Nvidia as every other major player in the AI space, it has to compete with them to secure adequate compute resources for its operations. OpenAI CFO Sarah Friar told Bloomberg that OpenAI might sell additional AI-related services at some point in the future, with a focus on setting up data centers optimized for AI workloads.

While that has the power to be a decidedly profitable venture, it highlights OpenAI’s murky future towards profitability. AI’s shine is starting to fade among investors, while companies like OpenAI and Meta grapple with the complexity of developing advanced models. Among all of this, one thing is certain: the race to develop the most advanced AI models is becoming more difficult, and the industry is still waiting with bated breath for the tech to deliver the promised revolution.

Dogs and drones join forest battle against eight-toothed beetle

Sean Gallup/Getty Images A close up shot of Ips Typographus, a light brown hairy beetle with three front legs visible one slightly extended out. It is walking along the bark of a logged spruce tree.

It is smaller than your fingernail, but this hairy beetle is one of the biggest single threats to the UK’s forests.

The bark beetle has been the scourge of Europe, killing millions of spruce trees, yet the government thought it could halt its spread to the UK by checking imported wood products at ports.

But this was not their entry route of choice – they were being carried on winds straight over the English Channel.

Now, UK government scientists have been fighting back, with an unusual arsenal including sniffer dogs, drones and nuclear waste models.

They claim the UK has eradicated the beetle from at risk areas in the east and south east. But climate change could make the job even harder in the future.

The spruce bark beetle, or Ips typographus, has been munching its way through the conifer trees of Europe for decades, leaving behind a trail of destruction.

The beetles rear and feed their young under the bark of spruce trees in complex webs of interweaving tunnels called galleries.

When trees are infested with a few thousand beetles they can cope, using resin to flush the beetles out.

But for a stressed tree its natural defences are reduced and the beetles start to multiply.

“Their populations can build to a point where they can overcome the tree defences – there are millions, billions of beetles,” explained Dr Max Blake, head of tree health at the UK government-funded Forestry Research.

“There are so many the tree cannot deal with them, particularly when it is dry, they don’t have the resin pressure to flush the galleries.”

Since the beetle took hold in Norway over a decade ago it has been able to wipe out 100 million cubic metres of spruce, according to Rothamsted Research.

‘Public enemy number one’

As Sitka spruce is the main tree used for timber in the UK, Dr Blake and his colleagues watched developments on continental Europe with some serious concern.

“We have 725,000 hectares of spruce alone, if this beetle was allowed to get hold of that, the destructive potential means a vast amount of that is at risk,” said Andrea Deol at Forestry Research. “We valued it – and it’s a partial valuation at £2.9bn per year in Great Britain.”

There are more than 1,400 pests and diseases on the government’s plant health risk register, but Ips has been labelled “public enemy number one”.

The number of those diseases has been accelerating, according to Nick Phillips at charity The Woodland Trust.

“Predominantly, the reason for that is global trade, we’re importing wood products, trees for planting, which does sometimes bring ‘hitchhikers’ in terms of pests and disease,” he said.

Forestry Research had been working with border control for years to check such products for Ips, but in 2018 made a shocking discovery in a wood in Kent.

“We found a breeding population that had been there for a few years,” explained Ms Deol.

“Later we started to pick up larger volumes of beetles in [our] traps which seemed to suggest they were arriving by other means. All of the research we have done now has indicated they are being blown over from the continent on the wind,” she added.

Daegan Inward/Forestry Research Barren spruce trees stripped of branches and leaves stand in a field, on the ground are some felled trees arranged in groups. The floor is covered in low level shrubland and moss. In the background is a spruce forest set against a cloudy sky — The Ips beetle has left some spruce forests in Denmark and other European countries decimated

The team knew they had to act quickly and has been deploying a mixture of techniques that wouldn’t look out of place in a military operation.

Drones are sent up to survey hundreds of hectares of forest, looking for signs of infestation from the sky – as the beetle takes hold, the upper canopy of the tree cannot be fed nutrients and water, and begins to die off.

But next is the painstaking work of entomologists going on foot to inspect the trees themselves.

“They are looking for a needle in a haystack, sometimes looking for single beetles – to get hold of the pioneer species before they are allowed to establish,” Andrea Deol said.

In a single year her team have inspected 4,500 hectares of spruce on the public estate – just shy of 7,000 football pitches.

Such physically-demanding work is difficult to sustain and the team has been looking for some assistance from the natural and tech world alike.

When the pioneer Spruce bark beetles find a suitable host tree they release pheromones – chemical signals to attract fellow beetles and establish a colony.

But it is this strong smell, as well as the smell associated with their insect poo – frass – that makes them ideal to be found by sniffer dogs.

Early trials so far have been successful. The dogs are particularly useful for inspecting large timber stacks which can be difficult to inspect visually.

The team is also deploying cameras on their bug traps, which are now able to scan daily for the beetles and identify them in real time.

“We have [created] our own algorithm to identify the insects. We have taken about 20,000 images of Ips, other beetles and debris, which have been formally identified by entomologists, and fed it into the model,” said Dr Blake.

Some of the traps can be in difficult to access areas and previously had only been checked every week by entomologists working on the ground.

The result of this work means that the UK has been confirmed as the first country to have eradicated Ips Typographus in its controlled areas, deemed to be at risk from infestation, and which covers the south east and east England.

“What we are doing is having a positive impact and it is vital that we continue to maintain that effort, if we let our guard down we know we have got those incursion risks year on year,” said Ms Deol.

Tony Jolliffe/BBC A stack of cut timber logs are to the left of the image in some tall grass. On the right stands a woman in blue jeans, a t-shirt and red gilet guiding a white and brown spaniel dog along the logs. The dog is wearing an orange harness and lead. In the background a white 4x4 truck sits on a gravel path to the right. — Sniffer dogs are piloted to sniff out the spruce bark beetle at a test ground in the Alice Holt forest in Hampshire

And those risks are rising. Europe has seen populations of Ips increase as they take advantage of trees stressed by the changing climate.

Europe is experiencing more extreme rainfall in winter and milder temperatures meaning there is less freezing, leaving the trees in waterlogged conditions.

This coupled with drier summers leaves them stressed and susceptible to falling in stormy weather, and this is when Ips can take hold.

With larger populations in Europe the risk of Ips colonies being carried to the UK goes up.

The team at Forestry Research has been working hard to accurately predict when these incursions may occur.

“We have been doing modelling with colleagues at the University of Cambridge and the Met Office which have adapted a nuclear atmospheric dispersion model to Ips,” explained Dr Blake. “So, [the model] was originally used to look at nuclear fallout and where the winds take it, instead we are using the model to look at how far Ips goes.”

Nick Phillips at The Woodland Trust is strongly supportive of the government’s work but worries about the loss of ancient woodland – the oldest and most biologically-rich areas of forest.

Commercial spruce have long been planted next to such woods, and every time a tree hosting spruce beetle is found, it and neighbouring, sometimes ancient trees, have to be removed.

“We really want the government to maintain as much of the trees as they can, particularly the ones that aren’t affected, and then also when the trees are removed, supporting landowners to take steps to restore what’s there,” he said. “So that they’re given grants, for example, to be able to recover the woodland sites.”

The government has increased funding for woodlands in recent years but this has been focused on planting new trees.

“If we only have funding and support for the first few years of a tree’s life, but not for those woodlands that are 100 or century years old, then we’re not going to be able to deliver nature recovery and capture carbon,” he said.

AI Tool Flags Predatory Journals, Building a Firewall for Science

Summary: A new AI system developed by computer scientists automatically screens open-access journals to identify potentially predatory publications. These journals often charge high fees to publish without proper peer review, undermining scientific credibility.

The AI analyzed over 15,000 journals and flagged more than 1,000 as questionable, offering researchers a scalable way to spot risks. While the system isn’t perfect, it serves as a crucial first filter, with human experts making the final calls.

A team of computer scientists led by the University of Colorado Boulder has developed a new artificial intelligence platform that automatically seeks out “questionable” scientific journals.

The study, published Aug. 27 in the journal “Science Advances,” tackles an alarming trend in the world of research.

Daniel Acuña, lead author of the study and associate professor in the Department of Computer Science, gets a reminder of that several times a week in his email inbox: These spam messages come from people who purport to be editors at scientific journals, usually ones Acuña has never heard of, and offer to publish his papers—for a hefty fee.

Such publications are sometimes referred to as “predatory” journals. They target scientists, convincing them to pay hundreds or even thousands of dollars to publish their research without proper vetting.

“There has been a growing effort among scientists and organizations to vet these journals,” Acuña said. “But it’s like whack-a-mole. You catch one, and then another appears, usually from the same company. They just create a new website and come up with a new name.”

His group’s new AI tool automatically screens scientific journals, evaluating their websites and other online data for certain criteria: Do the journals have an editorial board featuring established researchers? Do their websites contain a lot of grammatical errors?

Acuña emphasizes that the tool isn’t perfect. Ultimately, he thinks human experts, not machines, should make the final call on whether a journal is reputable.

But in an era when prominent figures are questioning the legitimacy of science, stopping the spread of questionable publications has become more important than ever before, he said.

“In science, you don’t start from scratch. You build on top of the research of others,” Acuña said. “So if the foundation of that tower crumbles, then the entire thing collapses.”

The shake down

When scientists submit a new study to a reputable publication, that study usually undergoes a practice called peer review. Outside experts read the study and evaluate it for quality—or, at least, that’s the goal.

A growing number of companies have sought to circumvent that process to turn a profit. In 2009, Jeffrey Beall, a librarian at CU Denver, coined the phrase “predatory” journals to describe these publications.

Often, they target researchers outside of the United States and Europe, such as in China, India and Iran—countries where scientific institutions may be young, and the pressure and incentives for researchers to publish are high.

“They will say, ‘If you pay $500 or $1,000, we will review your paper,’” Acuña said. “In reality, they don’t provide any service. They just take the PDF and post it on their website.”

A few different groups have sought to curb the practice. Among them is a nonprofit organization called the Directory of Open Access Journals (DOAJ).

Since 2003, volunteers at the DOAJ have flagged thousands of journals as suspicious based on six criteria. (Reputable publications, for example, tend to include a detailed description of their peer review policies on their websites.)

But keeping pace with the spread of those publications has been daunting for humans.

To speed up the process, Acuña and his colleagues turned to AI. The team trained its system using the DOAJ’s data, then asked the AI to sift through a list of nearly 15,200 open-access journals on the internet.

Among those journals, the AI initially flagged more than 1,400 as potentially problematic.

Acuña and his colleagues asked human experts to review a subset of the suspicious journals. The AI made mistakes, according to the humans, flagging an estimated 350 publications as questionable when they were likely legitimate. That still left more than 1,000 journals that the researchers identified as questionable.

“I think this should be used as a helper to prescreen large numbers of journals,” he said. “But human professionals should do the final analysis.”

A firewall for science

Acuña added that the researchers didn’t want their system to be a “black box” like some other AI platforms.

“With ChatGPT, for example, you often don’t understand why it’s suggesting something,” Acuña said. “We tried to make ours as interpretable as possible.”

The team discovered, for example, that questionable journals published an unusually high number of articles. They also included authors with a larger number of affiliations than more legitimate journals, and authors who cited their own research, rather than the research of other scientists, to an unusually high level.

The new AI system isn’t publicly accessible, but the researchers hope to make it available to universities and publishing companies soon. Acuña sees the tool as one way that researchers can protect their fields from bad data—what he calls a “firewall for science.”

“As a computer scientist, I often give the example of when a new smartphone comes out,” he said.

“We know the phone’s software will have flaws, and we expect bug fixes to come in the future. We should probably do the same with science.”

Abstract

Estimating the predictability of questionable open-access journals

Questionable journals threaten global research integrity, yet manual vetting can be slow and inflexible.

Here, we explore the potential of artificial intelligence (AI) to systematically identify such venues by analyzing website design, content, and publication metadata.

Evaluated against extensive human-annotated datasets, our method achieves practical accuracy and uncovers previously overlooked indicators of journal legitimacy.

By adjusting the decision threshold, our method can prioritize either comprehensive screening or precise, low-noise identification.

At a balanced threshold, we flag over 1000 suspect journals, which collectively publish hundreds of thousands of articles, receive millions of citations, acknowledge funding from major agencies, and attract authors from developing countries.

Error analysis reveals challenges involving discontinued titles, book series misclassified as journals, and small society outlets with limited online presence, which are issues addressable with improved data quality.

Our findings demonstrate AI’s potential for scalable integrity checks, while also highlighting the need to pair automated triage with expert review.
