One question that Geoffrey Hinton, the Godfather of AI says OpenAI's GPT-4 still gets wrong
Geoffrey Hinton
, the
Godfather of AI
has admitted that he sometimes trusts his favorite chatbot more than he should. In a recent interview with CBS, Hinton revealed that he uses
OpenAI
's GPT-4 and he tends to believe what GPT-4 tells him, even though he knows he should be more careful. 'I tend to believe what it says, even though I should probably be suspicious,' he said. Sharing an example from his own experience, he said that he once asked GPT-4 a simple riddle:
"Sally has three brothers. Each of her brothers has two sisters. How many sisters does Sally have?"
The correct answer is one as Sally herself is one of the two sisters, and each brother has the same two sisters. But GPT-4 answered two, which surprised Hinton.
"It surprises me. It surprises me it still screws up on that,"
he said during the interview.

Geoffrey Hinton on the limits of AI
Stating that while GPT-4 is very advanced, it's not perfect, he said 'It's an expert at everything. It's not a very good expert at everything.'
Still, Hinton believes future AI models will improve. When asked if GPT-5 would get the riddle right, he replied, "Yeah, I suspect."
OpenAI launched GPT-4 in 2023 and became popular for clearing difficult exams like the SAT, GRE, and bar exam. In May 2024, OpenAI released GPT-4o, which became the default model for ChatGPT.
The company recently unveiled new models—GPT-4.1,
GPT-4.1
Mini, and GPT-4.1 Nano that are designed to outperform previous iterations, offering developers more efficient and cost-effective AI solutions.
One of the standout features of GPT-4.1 is its expanded context window, supporting up to 1 million tokens, significantly surpassing the 128,000-token limit of its predecessor, GPT-4o. This enhancement allows the model to process and understand larger datasets, making it particularly effective for complex tasks such as analysing extensive codebases or lengthy documents.
Additionally, GPT-4.1 delivers notable gains in coding performance, showing a 21% improvement over GPT-4o and a 27% increase compared to GPT-4.5.

SEC's crypto confusion deepens as next-gen ETFs test limits
A new line of yield-chasing crypto funds is forcing the Securities and Exchange Commission to confront unresolved gaps in its regulatory framework, just as the Trump administration eases oversight of digital assets. The immediate dispute centres on two proposed funds from ETF firms REX Financial and Osprey Funds that would allow investors to earn rewards by deploying Ether and Solana tokens to help validate blockchain transactions, a process known as staking. The firms said they had cleared an initial SEC registration hurdle last week, but agency staff took the unusual step of objecting that very same evening. Staff warned the products may not meet standards to qualify as investment companies under federal law, raising broader questions about the regulation of a hot corner of the crypto-investment world. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Cristiana Oliveira mostra a sua figura perfeita em novas fotos 33 Bridges Undo SEC staff noted that to meet the definition of an investment company, a firm must primarily invest in securities. That's a problem when it comes to digital assets: there are no clear lines around what crypto activities trip securities laws and what don't. Crypto Tracker TOP COIN SETS Web3 Tracker 1.21% Buy DeFi Tracker 0.98% Buy NFT & Metaverse Tracker -0.27% Buy BTC 50 :: ETH 50 -0.94% Buy Smart Contract Tracker -1.53% Buy TOP COINS (₹) Solana 12,955 ( 2.42% ) Buy XRP 187 ( 2.37% ) Buy Bitcoin 9,000,570 ( 1.77% ) Buy BNB 55,543 ( 1.14% ) Buy Ethereum 213,477 ( 1.11% ) Buy 'When ETFs generate income from staking, they may start to resemble traditional investment companies under the Investment Company Act — especially if investors are relying on the managerial efforts of others to earn those returns,' said Adam Gana, an attorney at law firm Gana Weinstein LLP. 'However, these types of ETFs are testing the boundaries of what counts as an investment company, and the SEC is sending mixed signals.' Did you Know? The world of cryptocurrencies is very dynamic. Prices can go up or down in a matter of seconds. Thus, having reliable answers to such questions is crucial for investors. View Details » Gana added that 'just because you throw some stocks into the mix doesn't mean the SEC will look the other way.' Live Events The SEC, REX and Osprey declined to comment. The general counsel at REX said earlier that the firm expected to satisfy the SEC's questions. The crypto industry has long argued that many tokens aren't securities and shouldn't fall under the SEC rules. Under Trump, the agency has appeared open to these arguments, and its new chair, Paul Atkins, is a proponent of digital currencies. SEC staff guidance has signalled that memecoins and stablecoins may fall outside securities definitions. As recently as May 29, the staff said federal securities laws generally don't apply to staking activities — further complicating the regulatory picture as firms try to launch novel products. These piecemeal statements create inconsistent policy, according to Corey Frayer, director of investor protection at the Consumer Federation of America. 'The SEC and the industry don't get to treat crypto assets as securities when it's convenient, and not as securities when they want weaker regulation,' said Frayer, who served as a senior adviser to former SEC Chair Gary Gensler, a frequent target of crypto industry scorn. At the crux of the matter is the so-called Howey test , which comes from a 1946 Supreme Court decision that still governs securities classification. Under the test, an asset can be considered a security — and thus will fall under SEC purview — if investors contribute capital with the expectation derived from the managerial efforts of others. Bitcoin is generally considered a commodity but the status of other tokens like Ether and Solana are less clear. SEC Commissioner Hester Peirce, head of the agency's crypto task force, took the unusual step of highlighting the SEC staff's queries about whether the proposed funds met the definition. 'I have those same questions,' Peirce wrote in a post on X. Donald Trump embraced the digital-asset industry during his reelection campaign, pledging to make the US the 'crypto capital of the planet.' Since re-entering the White House, he has established a national stockpile of Bitcoin, anointed a 'crypto czar' and welcomed memecoin enthusiasts to a private dinner in Washington. Firms have recently been successful in resolving SEC staff concerns about novel offerings. Earlier this year, agency staffers rebuked an ETF by State Street Corp. and Apollo Global Management — the world's first to invest in private credit — hours after the fund listed over concerns about the fund's liquidity and its ability to comply with valuation rules. The firms took action to rectify the issues. Also read: Thanks, Mr Sanjay Malhotra for giving wings to investors' dreams Crypto executives are optimistic that US regulators will eventually greenlight the staking ETFs. 'They've followed a crawl-walk-run approach — first futures ETFs, then spot ETFs, and hopefully staking ETFs,' said Matt Hougan, chief investment officer at Bitwise Asset Management Inc., which acquired an Ethereum staking platform last year. 'I'm hopeful we'll get to the finish line soon.'

Who is James Fishback? Doge architect steps away the moment Musk feuds with Trump; says 'it's time for Tesla CEO to apologize'
James Fishback James Fishback, the principal architect of the "DOGE checks" initiative, announced on Friday his withdrawal from the movement following Elon Musk's criticism of Donald Trump and demanded that Tesla CEO apologise to the President. "I believed in Elon Musk's vision to shrink government and make it work better for Americans. I'm proud of the DOGE Dividend proposal I developed and will keep working with the administration to return savings to taxpayers." Fishback said. "The truth is that Elon set expectations that he relayed to the President, me, and the country that he did not come close to fulfilling. That's disappointing, but okay. What's not okay is his baseless personal attacks against President Trump," he added. Praising President Trump, Fishback said that he is a once-in-a-century leader. He also said that the president won the popular vote, the Electoral College, and all seven swing states by championing the priorities in his Big Beautiful Bill which Musk said that he wants to 'kill.' President Trump has shown grace and patience at a time when Elon's behavior is disappointing and frankly downright disturbing, Fishback said and demanded aplology from Musk. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 2 BHKs starts at ₹ 72.6 Lakh | No Floor rise | Zero PLC Mahindra Happinest Tathawade Get Quote Undo He said, "It's time for Elon to apologize to the President and his family, cool off, and get back to work on inventing the future at Tesla and SpaceX." Who is James Fishback? The founder of the investment firm, aged 30, was raised by a bus driver and a Colombian immigrant. He left Georgetown University to start a hedge fund when he was 21, as reported by MarketWatch. According to the LinkedIn profile, in his professional journey includes working at Greenlight Capital in 2021, followed by establishing Azoria in 2023, where he currently holds the CEO position. Additionally, he leads Incubate Debate, a non-profit organisation helping secondary school students develop debating skills. Currently, he is involved in legal proceedings with Greenlight Capital. The company claims he misrepresented his position, whilst he has filed a countersuit for defamation. In December, he visited Trump's Mar-a-Lago to introduce Azoria Meritocracy ETF, which aims to invest in S&P 500 companies avoiding diversity, equity and inclusion practices. He has connections with former DOGE representative Vivek Ramaswamy and appeared on his podcast in November, Newsweek reported. Regarding the origin of the "DOGE Dividend" proposal, he revealed to Newsweek that the concept occurred to him during sleep. He stated, "It came to me in a dream. I woke up and called our Head of Research at Azoria, and we drafted the proposal during a two-hour lunch at Capital Grille." His "DOGE Dividends" concept aligns with his broader perspective of governmental rewards for citizens who identify wasteful expenditure. He stated, "... DOGE can save even more and as a result deliver an even bigger DOGE Dividend check to hard-working Americans." The proposal indicates that approximately 79 million American households could receive direct payments for reporting inefficiencies, potentially leading to increased savings. Sceptics suggest that while the plan is ambitious, it could potentially increase inflation and might be perceived as politically motivated rather than genuine financial reform. Fishback, who established a self-described "free thinking" investment company, rose to prominence amongst conservatives when he suggested distributing $5,000 stimulus payments to American taxpayers, which would be funded through DOGE's anticipated government savings. Despite never officially becoming part of DOGE, Fishback's "DOGE checks" concept received endorsement from Musk on X and caught Trump's attention, who showed interest in a "DOGE dividend." In December, Fishback introduced his anti-woke investment fund at Trump's Mar-a-Lago estate.

Just a few days ago, India overtook Japan to become the fourth-largest economy in the world and is expected to soon overtake Germany to become the third-largest economy, he said. Live Events The economic growth spurt in India can be traced to several proximate factors.
