China’s CATL says it has overtaken BYD on 5-minute EV battery charging time
Leading supplier says Shenxing cells can achieve 520km range compared with BYD’s 470km

CATL has unveiled upgraded battery cells it claims can offer faster charging for electric vehicles than its rival BYD, putting the two Chinese groups ahead of competitors in the race to overcome a major barrier to the shift away from petrol vehicles.

The world’s biggest electric vehicle battery maker said on Monday that a new version of its flagship Shenxing battery cell could offer a 520km range from just five minutes of charging time. 

Last month, BYD shocked the industry by unveiling a new charging system that could add about 470km in range to its batteries in about the same time.

The claims by the Chinese battery groups would put them ahead of major western rivals. At present, Tesla vehicles can be charged up to 200 miles (321km) in added range in 15 minutes, while Germany’s Mercedes-Benz recently launched its all-electric CLA compact sedan, which can be charged for up to 325km within 10 minutes using a fast-charging station. 

Analysts have said the deployment of high-speed charging systems from BYD and CATL will help to eradicate consumer fears about EV driving range, even though there are questions as to how fast the companies can bring these technologies outside China amid rising geopolitical tensions. 

The second generation of the Shenxing battery, which boasts a range of 800km on one charge, can achieve a peak charging speed of 2.5km per second, the company said at a media event ahead of this week’s Shanghai auto show.

“We look forward to collaborating with more industry leaders to push the limits of supercharging through true innovation,” said CATL’s chief technology officer Gao Huan, adding that he wanted the new batteries to become “the standard for electric vehicles”. 

Huan said the new Shenxing battery would be installed in more than 67 EV models this year. He later told reporters that energy density would not be sacrificed as a trade-off for fast charging.

During its tech day, CATL also unveiled its new sodium-ion battery, which it said would go into mass production in December. The new battery brand called Naxtra is able to give a range of about 200km for a hybrid vehicle and 500km for an electric vehicle, according to Huan. 

Sodium-ion batteries are seen as a cheaper and safer alternative to the lithium-based batteries widely used for energy storage, because they work better at both very high and low temperatures. But the amount of energy they can produce relative to their size has long lagged behind lithium batteries, making sodium cells impractical until now. 

The new technology has also been closely watched as a potential solution to reduce the world’s dependence on China for critical minerals, since sodium-ion batteries do not use lithium resources. 

At the event, Huan claimed the new sodium-ion battery would enable the industry’s shift from “single resource dependence” to “energy freedom” and reshape the global energy landscape.

He added that he was in discussions with several companies about using sodium-ion batteries in their vehicles.

TechCrunch : OpenAI’s o3 AI model scores lower on a benchmark than the company i

OpenAI’s o3 AI model scores lower on a benchmark than the company initially implied

A discrepancy between first- and third-party benchmark results for OpenAI’s o3 AI model is raising questions about the company’s transparency and model testing practices.

When OpenAI unveiled o3 in December, the company claimed the model could answer just over a fourth of questions on FrontierMath, a challenging set of math problems. That score blew the competition away — the next-best model managed to answer only around 2% of FrontierMath problems correctly.

“Today, all offerings out there have less than 2% [on FrontierMath],” Mark Chen, chief research officer at OpenAI, said during a livestream. “We’re seeing [internally], with o3 in aggressive test-time compute settings, we’re able to get over 25%.”

As it turns out, that figure was likely an upper bound, achieved by a version of o3 with more computing behind it than the model OpenAI publicly launched last week.

Epoch AI, the research institute behind FrontierMath, released results of its independent benchmark tests of o3 on Friday. Epoch found that o3 scored around 10%, well below OpenAI’s highest claimed score.

OpenAI has released o3, their highly anticipated reasoning model, along with o4-mini, a smaller and cheaper model that succeeds o3-mini.

That doesn’t mean OpenAI lied, per se. The benchmark results the company published in December show a lower-bound score that matches the score Epoch observed. Epoch also noted its testing setup likely differs from OpenAI’s, and that it used an updated release of FrontierMath for its evaluations.

“The difference between our results and OpenAI’s might be due to OpenAI evaluating with a more powerful internal scaffold, using more test-time [computing], or because those results were run on a different subset of FrontierMath (the 180 problems in frontiermath-2024-11-26 vs the 290 problems in frontiermath-2025-02-28-private),” wrote Epoch.

According to a post on X from the ARC Prize Foundation, an organization that tested a pre-release version of o3, the public o3 model “is a different model […] tuned for chat/product use,” corroborating Epoch’s report.

“All released o3 compute tiers are smaller than the version we [benchmarked],” wrote ARC Prize. Generally speaking, bigger compute tiers can be expected to achieve better benchmark scores.

Re-testing released o3 on ARC-AGI-1 will take a day or two. Because today’s release is a materially different system, we are re-labeling our past reported results as “preview”:

o3-preview (low): 75.7%, $200/task
o3-preview (high): 87.5%, $34.4k/task

Above uses o1 pro pricing…

OpenAI’s own Wenda Zhou, a member of the technical staff, said during a livestream last week that the o3 in production is “more optimized for real-world use cases” and speed versus the version of o3 demoed in December. As a result, it may exhibit benchmark “disparities,” he added.

“[W]e’ve done [optimizations] to make the [model] more cost efficient [and] more useful in general,” Zhou said. “We still hope that — we still think that — this is a much better model […] You won’t have to wait as long when you’re asking for an answer, which is a real thing with these [types of] models.”

Granted, the fact that the public release of o3 falls short of OpenAI’s testing promises is a bit of a moot point, since the company’s o3-mini-high and o4-mini models outperform o3 on FrontierMath, and OpenAI plans to debut a more powerful o3 variant, o3-pro, in the coming weeks.

It is, however, another reminder that AI benchmarks are best not taken at face value — particularly when the source is a company with services to sell.

Benchmarking “controversies” are becoming a common occurrence in the AI industry as vendors race to capture headlines and mindshare with new models.

In January, Epoch was criticized for waiting to disclose funding from OpenAI until after the company announced o3. Many academics who contributed to FrontierMath weren’t informed of OpenAI’s involvement until it was made public.

More recently, Elon Musk’s xAI was accused of publishing misleading benchmark charts for its latest AI model, Grok 3. Just this month, Meta admitted to touting benchmark scores for a version of a model that differed from the one the company made available to developers.

FT : Crypto casino takings top $80bn as gamblers bypass blocks

Crypto casino takings top $80bn as gamblers bypass blocks
Platforms now rival traditional betting groups in scale despite their services being illegal in most countries

Crypto casino takings have soared to tens of billions of dollars a year, new data shows, as gamblers bypass blocks in their home countries to bet on unregulated offshore platforms.

Despite being illegal in most countries, wagers paid in cryptocurrency last year generated $81.4bn in gross gaming revenue (GGR), the difference between bets taken in and winnings paid out, according to research by anti-online-crime platform Yield Sec — a fivefold rise since 2022.

“It’s explosive growth everywhere,” said Yield Sec founder Ismail Vali.

While crypto gambling sites are blocked in jurisdictions from the US and China to the EU and UK, they remain easily accessible via VPN, mirror links or URL redirection, experts, campaigners and former users told the Financial Times.

“Consumers know this,” according to Jordan Lea, a former problem gambler who now campaigns against the industry’s harms. He said “guides as to how you circumnavigate the geo-blocking” were freely available online and often offered by influencers who “specifically push” users in, while crypto casino user accounts could be bought on peer-to-peer marketplaces.

Incorporated in jurisdictions where crypto gambling is legal, such as Curaçao, Malta, the Isle of Man and Gibraltar, companies that operate crypto casinos, including Stake, Rollbit and Roobet, now rival the biggest traditional gambling groups in scale.

Stake, operated by Curaçao-incorporated Medium Rare, claims to account for up to 4 per cent of total transactions on the global Bitcoin network, with 25mn users placing 300bn bets on the platform since its 2017 launch. Its GGR last year was $4.7bn, up 80 per cent from 2022, according to the company.

That makes it a serious competitor to some of the world’s biggest traditional gambling groups. Entain and Flutter reported total revenues for last year of £5bn and $14bn, respectively, while Bet365’s revenue for the year to March 2024 was £3.7bn. None of the three report GGR.


Stake does not regard itself as a crypto casino and says more than half of transactions on its platform are conducted in traditional currencies. It said users attempting to “gain unauthorised access by bypassing geoblocking via VPN . . . will not be able to use the platform”, and that what “content creators . . . choose to post is entirely their personal decision and is neither directed nor influenced by Stake”.

Stake said its operations “are conducted in full compliance with applicable laws and regulations, are legitimate and are fully licensed”. Users are subject to “stringent know your customer procedures and anti-money-laundering processes”, with KYC information required “when creating an account on Stake and on an ongoing basis depending on a range of risk factors”.

However, the FT was able to create a Stake crypto gambling account from London using a VPN and was not asked for proof of address or affordability documentation until after starting to play.

YieldSec, which says its technology allows it to “monitor all of the audience, all of their activity, all of the time across all forms of legal and illegal online gambling”, estimates there are tens of thousands of crypto casinos worldwide that cater to tens of millions of users. Deposits are on average 10 times higher than those on regulated sites, according to the group.

In the UK and US, gambling on offshore unregulated websites via a VPN is not illegal. Offshore operators, however, may commit an offence if they “provide facilities” to UK residents, according to Richard Williams, a UK lawyer who specialises in gambling. Stake.com is not available to UK residents.


Matthew Litt, a US lawyer focused on abuses by online gaming companies, said that while “in theory the law would apply, there’s just no practical way to get to them.”

James Noyes of UK think-tank the Social Market Foundation said regulatory bodies and operators “turn a blind eye” to offshore companies providing services that domestic companies were forbidden from offering.

The UK Gambling Commission said “the responsibility for enforcing laws in other jurisdictions rests with authorities in those jurisdictions”.

While the promotion of illegal gambling is an offence in the UK, Williams said that for “remote advertising”, on streaming sites and social media, “it can also be argued that the content is not intended for British audiences”, so “enforcement . . . is problematic”.

Experts say an absence of spending limits and effective “know-your-customer” processes — such as ID, location and affordability checks — makes crypto casinos appealing to underage and problem gamblers, as well as those in countries such as China where all online betting is illegal. 

Users “are only on those sites because they don’t have a better option”, said Rob Minnick, a US-based campaigner and former underage crypto gambler. 

The use of crypto, whose value is inherently volatile, compounds the risks of gambling.

This “added element” of cryptocurrency made “the already deregulated gambling site . . . a double gamble”, said one former problem gambler who last year relapsed on Stake.com, accessing the site from the UK via a VPN.

Minnick said his crypto gambling via a VPN on Rollbit, a site operated by Curaçao-registered Bull Gaming, got him stuck in a “loop”. When cryptocurrency went up, he thought he had “passive income” with which to bet; when it went down, he gambled to chase his losses. 

Campaigners also warn of widespread misinformation about crypto casinos offering “fairer” odds than regulated websites. “I hear young people saying [that] quite commonly,” said Vali. “It’s because of them having seen too many [influencer] videos.”

Crypto casinos invest large sums in online marketing, including partnerships with influencers who often offer viewers vouchers and instructions on how to bypass geo restrictions.

Roobet and Rollbit also respectively partner with Premier League football clubs Chelsea and Leicester City.

Rollbit’s UK platform, which does not accept cryptocurrency, is regulated through a “white label” licence — which are sold to overseas gambling brands by UK providers licensed by the Gambling Commission, allowing them to operate in the UK without direct regulatory oversight.

Stake, which is the shirt sponsor of Everton football club, last month closed its non-crypto UK platform operated by Isle of Man-based white label provider TGP Europe after the Gambling Commission launched an investigation into a social media video promoting the brand and featuring an adult performer.

The commission said it would write to all three football clubs “with unlicensed sponsors” to warn of the “risks of promoting unlawful gambling websites”, and “seek assurance from the clubs that they have carried out due diligence on their white label partners and that consumers in Great Britain cannot transact with the unlicensed sites”.

In 2023 it fined TGP Europe more than £300,000 for anti-money laundering and social responsibility failings. 

Matt Zarb-Cousin, a campaigner who believes crypto gambling regulation is a “wild west” said “it would be very easy to just ban white labels”. Noyes and other experts say white label licences function as a “piggybacking mechanism”, allowing crypto casinos to reach a global audience. 

Since April 2024 the Gambling Commission has issued 287 cease-and- desist notices to providers “accepting and advertising crypto as a deposit method” in the UK.

Stake said it “operates under full regulatory oversight, holding licences in multiple regulated jurisdictions across global markets”.

TGP Europe, Roobet and Rollbit did not respond to requests for comment.
