Decagon and OpenAI deliver high-performance, fully automated customer support at scale Launched in 2023, Decagon⁠(opens in a new window) has quickly become a key player in automating customer support for companies like Curology, BILT, Duolingo, Eventbrite, Notion, and Substack. OpenAI’s models are crucial in their ability to deliver fast, reliable responses—without human intervention. From enterprises to tech-forward startups, Decagon helps businesses globally handle millions of support conversations without sacrificing quality or speed. The company uses a combination of OpenAI’s models—including GPT-3.5, 4, 4o, 4 Turbo, and OpenAI o1-mini—to deliver agentic bots that go beyond response generation and service the entire customer lifecycle.

Oil bosses have big hopes for the AI boom Data centres are fuelling demand for natural gas—for now This week 180,000 people descended on Abu Dhabi to attend ADIPEC, the global oil-and-gas industry’s biggest annual gathering. This year’s focus, perhaps unsurprisingly, was the nexus of artificial intelligence (AI) and energy. On the eve of the jamboree Sultan Al Jaber, chief executive of ADNOC, the Emirati national oil giant, convened a private meeting of big tech and big energy bosses. A survey of some 400 energy, tech and finance bigwigs released in conjunction with the event concluded that AI is set to transform the energy business by boosting efficiency and cutting greenhouse-gas emissions.

The 'bias machine': How Google tells you what you want to hear "We're at the mercy of Google." Undecided voters in the US who turn to Google may see dramatically different views of the world – even when they're asking the exact same question. Type in "Is Kamala Harris a good Democratic candidate", and Google paints a rosy picture. Search results are constantly changing, but last week, the first link was a Pew Research Center poll showing that "Harris energises Democrats". Next is an Associated Press article titled "Majority of Democrats think Kamala Harris would make a good president", and the following links were similar. But if you've been hearing negative things about Harris, you might ask if she's a "bad" Democratic candidate instead. Fundamentally, that's an identical question, but Google's results are far more pessimistic. "It's been easy to forget how bad Kamala Harris is," said an article from Reason Magazine in the top spot.

Forecasting vs. Predictive Analytics: The Obama Example Analytics can influence elections, not just predict them. This article explores how the Obama campaign used predictive analytics to outmaneuver traditional forecasting. Forecasting vs. Predictive Analytics Nate Silver’s forecasting predicted state outcomes, while Obama’s team used predictive analytics to score individual voters, targeting those most likely to be persuaded. Impact of Predictive Analytics The Obama campaign optimized interactions, avoiding “do-not-disturb” voters and improving ad spending effectiveness by 18%. Conclusion Predictive analytics enables organizations to shape outcomes through personalized insights, distinguishing it from forecasting’s broad predictions.
