ChatGPT took on a 50-year-old Atari — and lost
ChatGPT, arguably the world's most popular artificial intelligence (AI) chatbot, was humbled by a 50-year-old chess console. The Atari 2600 , first launched in 1977, outperformed ChatGPT in a recent experiment to the point that the AI chatbot conceded. The experiment was set up by cloud computing engineer Robert Jr. Caruso after ChatGPT itself insisted on playing chess against an Atari following a conversation about AI in chess. OpenAI 's chatbot "claimed it was a strong player in its own right and would easily beat Atari's Video Chess", Caruso said in a LinkedIn post. He expected it to be "a lighthearted stroll down retro memory lane" for the AI. His hopes were deflated once the match began. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Roteirizador Pathfind - O planejador de rotas mais completo do mercado Sistema TMS embarcador Saiba Mais Undo ChatGPT and its various AI models are being used for everything from answering emails, generating images and conducting in-depth research. Meanwhile, Atari 2600 sports an 8-bit, 1.1 MHz CPU which could only think 1–2 moves ahead. Live Events ChatGPT got absolutely wrecked on the beginner level, Caruso wrote. Despite being given a baseline board layout to identify pieces, ChatGPT confused rooks for bishops, missed pawn forks, and repeatedly lost track of pieces. The AI chatbot first blamed the Atari icons as too abstract to recognise, then failed to improve even after switching to the standard system of recording chess moves. Discover the stories of your interest Blockchain 5 Stories Cyber-safety 7 Stories Fintech 9 Stories E-comm 9 Stories ML 8 Stories Edtech 6 Stories At times, ChatGPT worked — analysing moves, explaining options and offering solid advice. At others, it made absurd suggestions — like sacrificing a knight to a pawn — or tried to move pieces that had already been captured, even during turns when it otherwise had an accurate view of the board, Caruso wrote. He said he had to stop ChatGPT from making awful moves and correct its board awareness multiple times per turn over 90 minutes. The modern tech kept promising it would improve 'if we just started over.' Eventually, it conceded the challenge to Atari. Technology has been better at chess than humans since the IBM Deep Blue supercomputer defeated the erstwhile champion and renowned grandmaster Gary Kasparov in 1997. The latest Stockfish chess engine have an estimated 3,600 points on the Elo chess ranking system, whereas the current world number one Magnus Carlsen has the highest rating among humans at around 2,800. One response to Caruso's post argued that ChatGPT does not employ artificial general intelligence (AGI), and only emulates human examples. Thus, it was unfair to test it in a game of logic like chess. Another pointed out that ChatGPT is not a chess engine, unlike Atari 2600, which despite being archaic, tracks the board and formulates moves.

Putin tells Trump Russia is ready for next round of Ukraine talks
Russian President Vladimir Putin told his US counterpart Donald Trump Saturday that Moscow was ready to hold a fresh round of peace talks with Kyiv after June 22, once the sides complete exchanging prisoners and soldiers' bodies. Ukraine's leader Volodymyr Zelensky meanwhile did not mention whether Ukraine would agree to the next round of talks, only saying that "the exchanges will be completed and the parties will discuss the next step." Putin and Trump held a call for the fifth time since the Republican took office and sought to reset relations with Moscow, in a stark pivot from the approach of his predecessor Joe Biden's administration. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Roteirizador Pathfind - O planejador de rotas mais completo do mercado Sistema TMS embarcador Saiba Mais Undo Trump's approach has stunned Washington's allies, raising doubts about the future of US aid to Kyiv and leaving Europe scrambling to work out how it can fill any gap in supplies if Trump decides to pull US military, financial and intelligence support. "Both leaders expressed satisfaction with their personal relations" during the call, in which they also discussed the escalating conflict between Iran and Israel, the Kremlin said. Live Events It added that the presidents "communicate in a businesslike manner and seek solutions to pressing issues on the bilateral and international agenda, no matter how complex these issues may be". 'Happy birthday' call Trump posted on Truth Social to say Putin had called "to very nicely wish me a Happy Birthday" on the day he turned 79, but that "more importantly" the two discussed the Iran-Israel crisis. "He feels, as do I, this war in Israel-Iran should end, to which I explained, his war should also end," Trump said, referring to the Russia-Ukraine conflict. Zelensky urged the United States to "shift tone" in its dialogue with Russia, saying it was "too warm" and would not help to end the fighting. "Any signals of reduced aid, or of treating Ukraine and Russia as equals, are deeply unfair. Russia is the aggressor. They started this war. They do not want to end it," the Ukrainian President said on X. The recent escalation sparked fears Washington might relocate resources at its expense, to beef up the defence of its close ally Israel which unleashed a large-scale attack on Iran Friday. "We would like to see aid to Ukraine not decrease because of this," he said. "Last time, this was a factor that slowed down aid to Ukraine." More soldiers exchanged Earlier on Saturday, Ukraine and Russia swapped prisoners in the fourth such exchange this week, part of a large-scale plan to bring back 1,000 wounded prisoners from each side and return bodies of killed soldiers. The prisoner agreement was the only visible result of two recent rounds of talks in Istanbul. Photos published by Zelensky on Telegram showed men of various ages, mostly with shaved heads, wearing camouflage and draped in Ukrainian flags. Some were injured, others disembarked from buses and hugged those welcoming them, or were seen calling someone by phone, sometimes covering their faces or smiling. Moscow's defence ministry released its own video showing men in uniforms holding Russian flags, clapping and chanting "Glory to Russia" and "hooray", some raising their fists in the air. As part of the Istanbul agreements, Kyiv also said it had received another 1,200 unidentified bodies from Russia. It said Moscow had said they were those of "Ukrainian citizens, including military personnel." Ukraine did not say whether it returned any bodies to Russia. Russia has rejected calls to halt its three-year offensive. It has demanded Ukraine cede territory and renounce Western military support if it wants peace. Since Russia sent troops into Ukraine in February 2022, the assault has forced millions of people to flee their homes as towns and cities across eastern Ukraine have been flattened by heavy bombardments. Meanwhile, Russia intensified its advances along the front line, especially on the northeastern Ukrainian region of Sumy, where it seeks to establish a "buffer zone". By doing it, Moscow seeks to protect its bordering region of Kursk, previously partly occupied by Ukraine. Zelensky said Russia's advance on Sumy was stopped and that Kyiv's forces had managed to retake one village. He also denied Moscow's earlier claims that its troops entered the Dnipropetrovsk region. He said 53,000 Russian soldiers were involved in the Sumy operation.

Is beating the benchmark enough? What the information ratio reveals
In a world increasingly leaning towards passive investing, how can you truly evaluate the value an active fund manager brings to the table? In this exclusive conversation, ET's Neha Vashishth speaks with Chirag Muni, who breaks down the Information Ratio—a lesser-known but powerful metric that goes beyond just returns and looks at how efficiently those returns are generated. Excerpts: by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Roteirizador Pathfind - O planejador de rotas mais completo do mercado Sistema TMS embarcador Saiba Mais Undo Q. Let's start with the basics—what exactly is the Information Ratio? Chirag Muni: The Information Ratio (IR) is a performance metric that measures a fund manager's ability to generate excess returns over a benchmark, adjusted for the volatility of those excess returns. It shows how effectively a manager delivers better risk-adjusted returns compared to the benchmark. A higher IR indicates more consistent and efficient outperformance, while a lower IR suggests the fund is underperforming relative to its benchmark. Live Events Let me give you a comparison: Suppose two large-cap fund managers both deliver a 15% return, beating their 12% benchmark by 3%. Now, if one of them took less risk than the other to achieve this, the Information Ratio will reflect that. The fund manager with the higher Information Ratio would be the preferred choice because he delivered the same return with less risk. This ratio highlights both consistency and efficiency in return generation. Q. How do you see the IR reshaping the way investors assess fund managers, especially in an era of passive investing? Chirag: Great question. There are two aspects here. First, should investors choose active or passive fund management? When we analysed mutual fund performance over the past five years—across categories like large-cap, flexi-cap, multi-cap, contra, etc.—we found that 60% to 100% of active funds beat the Nifty, and around 70% beat their own benchmarks, except in the large-cap category. So yes, if you choose the right fund, active strategies still offer superior excess returns. Passive funds can't outperform the benchmark—they just mirror it. Secondly, within active strategies, the Information Ratio helps you evaluate the quality of excess return. It allows you to choose fund managers who are not only outperforming but doing so with less risk. That's where this metric really becomes relevant. Q. How is Information Ratio different from other ratios? Chirag: Most investors use the Sharpe Ratio, which compares a fund's return to a risk-free rate like a 6.5% government bond, adjusted for volatility. But the Information Ratio compares the fund's return to its own benchmark, not to a risk-free asset. That makes it more relevant for mutual funds, because we're evaluating whether the manager added value over what the benchmark would have given. So, while Sharpe is useful, the Information Ratio gives a truer picture of a fund manager's active performance. Q. What's the ideal time frame to evaluate the Information Ratio? Chirag: Time frame is very important. Looking at short-term data can mislead you due to market noise and volatility. On the other hand, a very long-term period like 10 years might not reflect the current fund strategy or manager, as those could have changed. The ideal period is between three to five years. This allows you to evaluate consistent performance while accounting for a reasonably stable strategy and risk profile. Q. I noticed that multicap and contra funds often show a higher Information Ratio compared to large-cap or mid-cap funds over 3–5 years. Why is that? Chirag: Good observation. It's because of investment flexibility. In large-cap funds, 80% of the money must go to the top 100 stocks, leaving little room for creativity or deviation from the benchmark. That limits the potential to generate alpha or excess return. But in multicap, smallcap, flexicap, or contra funds, fund managers can explore beyond the benchmark and use different strategies. That freedom leads to higher alpha, and therefore, a better Information Ratio. Q. How should investors use Information Ratio in conjunction with other metrics like Alpha, Beta, or Sharpe Ratio when selecting funds? Chirag: You should never rely on any one ratio in isolation. Information Ratio shows how efficiently a fund manager has beaten the benchmark considering the risk taken. Alpha tells you how much excess return the fund generated. Beta indicates how sensitive the fund is to market movements—i.e., how volatile it is compared to the benchmark. Sharpe Ratio assesses return per unit of total risk, compared to a risk-free asset. Sortino Ratio focuses only on downside risk. The right approach is to combine all these and assess a fund from multiple angles—consistency, volatility, downside protection, and benchmark-beating ability. Q. How can one interpret whether an Information Ratio is good or not? Chirag: You don't need to calculate it yourself—it's already available in the fund fact sheets. You can simply compare the Information Ratio of a fund to the category average. For instance, in the focused fund category, ICICI Prudential Focused Fund has an Information Ratio of 0.9, while the category average is 0.07—a clear indication of superior risk-adjusted performance. In the smallcap space, Invesco India Smallcap Fund has a ratio of 0.5, compared to a 0.1 category average. So yes, the more positive the Information Ratio, the better. It means the fund manager is taking less risk for every unit of extra return. Q. What are some limitations of the Information Ratio? Are there risks to over-relying on it? Chirag: Absolutely. It's just one part of the puzzle. Choosing the right fund starts with knowing your market cap allocation, then shortlisting funds that consistently beat benchmarks, and only then applying tools like the Information Ratio. You can't make a decision solely based on this metric. A fund might have a good Information Ratio today but not fit your overall strategy or allocation. So, use it as a filter, not the final decision-maker. Q. Lastly, SEBI is pushing for greater fund disclosures and transparency. Should the Information Ratio be highlighted more prominently in fact sheets? Chirag: Definitely. Fact sheets are already loaded with data, but unless key metrics like the Information Ratio are better communicated and explained, investors won't benefit. If more people understand and look at the Information Ratio, they can hold their advisors accountable and make more informed, risk-conscious decisions. So yes, SEBI should definitely promote awareness and ensure standardized, visible reporting of such metrics.
