Google CEO Sundar Pichai Warns AI Bubble While Anthropic Claude Scores High

Global financial markets are currently grappling with significant concerns about a potential AI bubble, a sentiment echoed by prominent figures in the tech and finance sectors. On Tuesday, Google CEO Sundar Pichai issued a stark warning at the Web Summit in Lisbon, stating that no company would be safe if the AI bubble bursts. This caution contributed to a global stock market sell-off on November 18, 2025, with shares falling across Asia and Bitcoin hitting a seven-month low. Google's shares specifically dropped 4.5% following a mistake in a promotional video for its AI chatbot, Bard, while Microsoft's shares also dipped, reflecting investor apprehension about technology stocks. Joe Weisenthal, cohost of the "Odd Lots" podcast, shares a similar view, predicting a significant impact on the US economy and finance if the AI bubble eventually bursts. Legal expert Greg Ramos from Armstrong Teasdale and investor Michael Burry also voice concerns about tech giants' massive investments in AI infrastructure, drawing parallels to past tech booms and warning of overvaluation and overbuilding without sufficient demand. Despite these market anxieties, AI continues to expand into diverse applications, showcasing both its potential and its limitations. OpenAI's new app, Sora 2, for instance, is making it remarkably easy to create AI-generated videos, from a cat riding a motorcycle to Sam Altman on Mount Everest. However, this ease of creation also contributes to a flood of "AI slop" and raises concerns about deepfakes, as noted by deepfake expert Henry Ajder from the University of Cambridge. Meanwhile, OpenAI's ChatGPT platform experienced a service outage on November 18, rendering it inaccessible to users. Accuracy remains a critical challenge for AI models. A new benchmark, the AA-Omniscience Index by Artificial Analysis, measures "hallucination" rates, revealing that Anthropic's Claude 4.1 Opus scored highest with the lowest hallucination rate at 4.8. While other models like GPT-5.1 and Grok 4 showed high accuracy, their higher hallucination rates impacted their overall scores, underscoring that general intelligence does not always equate to low hallucination. AI's practical applications are rapidly evolving across various industries. In the mortgage sector, MMI received the 2025 AI Pioneer Award for its innovative use of AI, including ChatMMI for instant answers, MonitorBase for predictive borrower insights, Bonzo for personalized messages, and MMI One for automated customer outreach, all aimed at streamlining loan processes. Switzerland's Barry Callebaut is partnering with Chilean startup NotCo AI, utilizing its Giuseppe platform to create new chocolate recipes, a strategic move to combat high cocoa prices and declining demand. In finance, Bloomberg Intelligence's Philip Richards highlights AI's growing role in trading, risk management, compliance, and customer service, though the true value of AI's promised efficiency versus its high setup costs is still under evaluation. The human element in AI interaction also presents complexities. AI "griefbots," explored on November 18, 2025, use generative AI and personal data to imitate deceased loved ones, offering a new, immersive way for individuals to process grief and address unfinished business. Conversely, the AI tool Cluely, designed to assist in conversations, struggled to replicate a personal "conversational style," with the author finding it made their own conversations more difficult, suggesting AI cannot fully replace unique human interaction. The rapid adoption of AI is also reshaping foundational technologies. The 2025 Ryder Cup demonstrated the critical need for AI-ready networks, with HPE partnering to create a central hub using high-performance networks and AI-enabled cameras for real-time intelligence. These networks require ultra-low latency and specialized equipment to handle massive datasets. Concurrently, cloud security strategies are adapting to dynamic AI environments, moving beyond traditional platforms to monitor live system actions and AI prompt traffic for threats, a shift supported by Sweet Security's recent $75 million funding. Legal foresight is becoming increasingly important, especially concerning intellectual property and data privacy risks associated with large language models.

Anthropic AI Models Show Low Hallucination Rates

A new benchmark called the AA-Omniscience Index by Artificial Analysis measures how often AI models give wrong answers, known as "hallucinations." Anthropic's Claude 4.1 Opus scored highest at 4.8, showing the lowest hallucination rate among tested models. GPT-5.1 and Grok 4 followed. While some models like Grok 4 and GPT-5 had high accuracy, their high hallucination rates lowered their overall scores. The study found that an AI's general intelligence does not always mean it will have low hallucination. These findings are important for businesses using AI in fields that need accurate information.

Barry Callebaut Uses AI for Chocolate Recipes

On November 18, Switzerland's Barry Callebaut announced a partnership with Chilean startup NotCo AI. Barry Callebaut will use NotCo's artificial intelligence to create new chocolate recipes. This move aims to help the company deal with high cocoa prices and lower demand for its products. NotCo's platform, called Giuseppe, can scan products and suggest ingredient replacements, using a large database to simulate alternatives. Barry Callebaut CEO Peter Feld hopes this will make their innovation process more efficient and reduce trial and error.
