• OpenAI Study Reveals How People Use ChatGPT, a comprehensive research paper…

    OpenAI released a comprehensive research paper titled “How People Use ChatGPT,” authored by Aaron Chatterji, Tom Cunningham, David Deming, Zoë Hitzig, Christopher Ong, Carl Shan, and Kevin Wadman. The study analyzes the rapid adoption and usage patterns of ChatGPT, the world’s largest consumer chatbot, from its November 2022 launch through July 2025. By then, ChatGPT had amassed 700 million users—about 10% of the global adult population—sending 18 billion messages weekly, marking unprecedented technological diffusion.

    Using a privacy-preserving automated pipeline, the researchers classified a representative sample of conversations from consumer plans (Free, Plus, Pro). Key findings show non-work-related messages growing faster than work-related ones, rising from 53% to over 70% of usage. Work messages, while substantial, declined proportionally due to evolving user behavior within cohorts rather than demographic shifts. This highlights ChatGPT’s significant impact on home production and leisure, potentially rivaling its productivity effects in paid work.

    The paper introduces taxonomies to categorize usage. Nearly 80% of conversations fall into three topics: Practical Guidance (e.g., tutoring, how-to advice, ideation), Seeking Information (e.g., facts, current events), and Writing (e.g., drafting, editing, summarizing). Writing dominates work tasks at 40%, with two-thirds involving modifications to user-provided text. Contrary to prior studies, coding accounts for only 4.2% of messages, and companionship or emotional support is minimal (under 2%).

    A novel “Asking, Doing, Expressing” rubric classifies intents: Asking (49%, seeking info/advice for decisions), Doing (40%, task performance like writing/code), and Expressing (11%, sharing views). At work, Doing rises to 56%, emphasizing generative AI’s output capabilities. Mapping to O*NET work activities, 58% involve information handling and decision-making, consistent across occupations, underscoring ChatGPT’s role in knowledge-intensive jobs.

    Demographics reveal early male dominance (80%) narrowing to near parity by 2025. Users under 26 send nearly half of messages, with growth fastest in low- and middle-income countries. Educated professionals in high-paid roles use it more for work, aligning with economic value from decision support.

    The study used LLM classifiers validated against public datasets, ensuring privacy—no humans viewed messages. Appendices detail prompts, validation (high agreement on key tasks), and a ChatGPT timeline, including models like GPT-5.

    Overall, the paper argues ChatGPT enhances productivity via advice in problem-solving, especially for knowledge workers, while non-work uses suggest vast consumer surplus. As AI evolves, understanding these patterns informs its societal and economic impacts.

  • Google Releases VaultGemma: The Largest Differentially Private AI Model

    Google Research unveiled VaultGemma, a groundbreaking 1-billion-parameter language model, marking it as the largest open-source AI model trained from scratch with differential privacy (DP). This release, detailed in a blog post by Amer Sinha and Ryan McKenna, represents a significant milestone in building AI systems that prioritize user privacy while maintaining high utility. VaultGemma’s weights are now available on Hugging Face and Kaggle, accompanied by a technical report to foster further innovation in privacy-centric AI development.

    Differential privacy, a cornerstone of VaultGemma’s design, ensures robust protection of training data by injecting calibrated noise to prevent memorization. This approach guarantees that the model cannot reproduce sensitive information from its training dataset, offering a formal privacy guarantee at the sequence level (ε ≤ 2.0, δ ≤ 1.1e-10). In practical terms, this means that if a fact appears in only one training sequence, VaultGemma essentially “forgets” it, ensuring responses are statistically indistinguishable from a model untrained on that sequence. However, DP introduces trade-offs, including reduced training stability and increased computational costs, which Google’s new research addresses.

    The accompanying study, “Scaling Laws for Differentially Private Language Models,” conducted with Google DeepMind, provides a comprehensive framework for understanding these trade-offs. The research introduces DP scaling laws that model the interplay between compute, privacy, and data budgets. A key metric, the “noise-batch ratio,” compares the amount of privacy-preserving noise to batch size, simplifying the complex dynamics of DP training. Through extensive experiments, the team found that larger batch sizes are critical for DP models, unlike non-private training, where smaller models with larger batches often outperform larger models with smaller batches. These insights guide practitioners in optimizing training configurations for specific privacy and compute constraints.

    VaultGemma, built on the responsible and safe foundation of the Gemma 2 model, leverages these scaling laws to achieve compute-optimal training at scale. The team addressed challenges like Poisson sampling in DP-SGD (Stochastic Gradient Descent) by adopting scalable techniques that maintain fixed-size batches while preserving strong privacy guarantees. Performance tests show VaultGemma’s utility is comparable to non-private models from five years ago, such as GPT-2 (1.5B parameters), across benchmarks like HellaSwag, BoolQ, and TriviaQA. While a utility gap persists compared to non-DP models, Google’s research lays a roadmap to close it through advanced mechanism design.

    Empirical tests confirm VaultGemma’s privacy efficacy, showing no detectable memorization when prompted with training data prefixes. This release empowers the AI community to build safer, privacy-first models, with Google’s open-source approach fostering collaboration. The project acknowledges contributions from the Gemma and Google Privacy teams, including experts like Peter Kairouz and Brendan McMahan. As AI integrates deeper into daily life, VaultGemma stands as a pivotal step toward powerful, privacy-by-design AI, with potential to shape the future of responsible innovation.

  • Apple blocks EU users from new AirPods translation feature

    Apple has confirmed that its highly anticipated Live Translation feature for AirPods will not be available to users in the European Union at launch, citing compliance issues with the bloc’s stringent digital regulations. The restriction, quietly detailed on Apple’s iOS 26 feature availability page, affects millions of EU residents with Apple accounts registered in the region, preventing them from accessing the real-time audio translation capability powered by Apple Intelligence. Unveiled during Apple’s September 10, 2025, “Awe Dropping” event alongside the new AirPods Pro 3, the feature was positioned as a game-changer for multilingual communication, but EU users will have to wait indefinitely for its rollout.

    Live Translation enables seamless, real-time interpretation of conversations directly through compatible AirPods models, including the new Pro 3, Pro 2, and AirPods 4 with Active Noise Cancellation. When both parties wear supported earbuds, the system lowers the original audio via noise cancellation and delivers translated speech, creating a natural flow akin to subtitles in real life. For one-sided use, translations appear on the paired iPhone screen. Initial language support includes English, French, German, Portuguese, and Spanish, with Italian, Japanese, Korean, and Chinese slated for later this year. The feature requires an iPhone 15 Pro or newer running iOS 26, which launches next week, and relies on on-device processing for privacy.

    Apple explicitly states: “Live Translation with AirPods is not available if you are in the EU and your Apple Account Country or Region is also in the EU.” The company attributes the delay primarily to interoperability requirements under the Digital Markets Act (DMA), which mandates that large tech firms like Apple allow third-party access to core technologies to promote competition. A March 2025 European Commission decision exacerbated these obligations, forcing Apple to adapt features like Apple Intelligence. While user data protection laws such as the General Data Protection Regulation (GDPR) and the EU Artificial Intelligence Act were not cited as direct factors, experts suggest they contribute to the caution, given the feature’s handling of speech data and potential privacy implications.

    This isn’t Apple’s first clash with EU rules; Apple Intelligence features were delayed in the region until March 2025, and services like iPhone Mirroring remain restricted due to similar DMA pressures. The company has previously warned that such regulations could “compromise the integrity of our products” by risking user privacy and security. Notably, the restriction is geo-account specific: Non-EU users visiting Europe or EU users with non-EU accounts may still access the feature, potentially allowing workarounds like account changes.

    The decision has sparked backlash online, particularly ironic in multilingual Europe with 24 official languages. On X, users like @christiancalgie highlighted the economic irony: “EU regulations will block Apple’s new super helpful live translation feature on the new Airpods. The EU… the place in the world possibly most useful to have that feature. You starting to see why the economy’s going to hell in a handbasket?” Reddit’s r/apple thread, with over 1,100 upvotes, debated the move, with comments criticizing it as a tactic to pressure regulators or simply regulatory overreach, while others noted competitors like Google’s Pixel Buds have offered similar EU-available translation for years. @legendarygainz_ echoed the frustration: “Live translation feature for AirPods Pro 3 won’t work in the EU. Apple had to block the feature for regulatory reasons.”

    Apple has not announced a timeline for EU availability, but past patterns suggest resolution once compliance is achieved. In the meantime, the block underscores ongoing tensions between Big Tech and EU regulators, potentially impacting Apple’s market strategy in the region amid broader AI rollouts.

  • Microsoft Accelerates AI Self-Sufficiency with Plans for Massive In-House Chip Investments

    Microsoft is ramping up efforts to achieve greater independence in artificial intelligence by investing heavily in its own AI chip infrastructure, according to comments from AI CEO Mustafa Suleyman during an internal town hall meeting on September 11, 2025. This strategic push aims to reduce the company’s reliance on external partners like OpenAI and Nvidia, amid evolving partnerships and the escalating costs of AI development. The announcement, leaked via Business Insider, underscores Microsoft’s determination to build “self-sufficient” AI capabilities tailored to its diverse business portfolio, including Azure cloud services and productivity tools like Copilot.

    Suleyman emphasized the necessity of this move, stating, “It’s critical that a company of our size, with the diversity of businesses that we have, that we are, you know, able to be self sufficient in AI, if we choose to.” He revealed plans for “significant investments” in an in-house AI chip cluster, which would enable Microsoft to develop and train its own AI models without over-dependence on third-party hardware. This cluster is expected to support large-scale AI workloads, potentially powering custom foundational models for applications across Microsoft’s ecosystem. The initiative aligns with ongoing contract renegotiations with OpenAI, where Microsoft has already invested over $13 billion since 2019, but recent tensions have prompted diversification.

    This development builds on Microsoft’s existing custom silicon efforts, including the Azure Maia AI Accelerator and Azure Cobalt CPU, first unveiled in 2023 and expanded in 2024. The Maia series, optimized for generative AI tasks like those in Microsoft Copilot, uses advanced 5nm packaging from TSMC and features integrated liquid cooling for efficiency. However, earlier reports from June 2025 highlighted delays in the next-generation Maia chip, pushing mass production to 2026 and prompting interim solutions like the planned Maia 280 in 2027, which combines existing Braga chips for improved performance. Despite these setbacks, Suleyman’s comments signal renewed momentum, with Microsoft aiming to produce hundreds of thousands of in-house AI chips annually to compete with Nvidia’s dominance.

    The push for self-sufficiency comes as AI infrastructure demands skyrocket, with data centers projected to consume massive energy resources. By designing chips “from silicon to service,” Microsoft seeks to optimize for performance, cost, and security, offering customers more choices beyond Nvidia’s offerings. Partnerships with AMD, Intel, and Qualcomm will continue, but in-house development could lower costs and accelerate innovation for Azure-based AI services. Analysts view this as a response to Nvidia’s supply constraints and pricing pressures, positioning Microsoft alongside rivals like Amazon (with its Trainium chips) and Google (TPU series) in the custom AI hardware race.

    While details on the chip cluster’s timeline and budget remain undisclosed, the strategy could reshape Microsoft’s AI roadmap, enhancing its competitive edge in enterprise AI. However, challenges like design delays and talent competition persist, with Nvidia reportedly viewing Microsoft as its largest customer. As AI adoption grows, Microsoft’s self-sufficiency drive promises more efficient, tailored solutions but highlights the intensifying arms race in semiconductor innovation.
