Microsoft Shakes Up Copilot Leadership as AI Assistant Struggles for Adoption

Category: Enterprise AI Source: CNBC

Microsoft announced a major reorganization of its Copilot AI assistant team, freeing up AI chief Mustafa Suleyman to focus on building new generative AI models rather than product development. Former Snap executive Jacob Andreou will now oversee both commercial and consumer Copilot experiences, reporting directly to CEO Satya Nadella.

The restructuring comes as Copilot faces an uphill battle for market share. With only 6 million daily active users in February—dwarfed by ChatGPT’s 440 million and even Anthropic’s Claude at 9 million—Microsoft is doubling down on its “superintelligence” initiative. Suleyman emphasized that “the model is the product,” signaling a strategic pivot toward developing proprietary AI models that can compete with OpenAI’s offerings. Only 3% of commercial Office 365 users have adopted the Copilot add-on, despite Microsoft’s significant AI infrastructure investments.

The move reflects broader pressure on software companies to demonstrate ROI on AI spending, with the iShares Expanded Tech-Software Sector ETF down 19% this year. Microsoft will continue leveraging OpenAI intellectual property through 2032 while simultaneously building “enterprise-specific model lineages” optimized for cost efficiency.

Mistral Releases Leanstral: Open-Source Foundation for Formal Verification

Category: Model Releases Source: Mistral AI

Mistral AI unveiled Leanstral, the first open-source code agent specifically designed for Lean 4, a formal verification language used to prove mathematical theorems and verify software correctness. This release marks a significant step toward making formal methods accessible beyond academic research labs.

Lean 4 has gained traction in safety-critical software development, where mathematical proof of correctness is paramount. However, the language’s steep learning curve has limited adoption. Leanstral aims to bridge this gap by enabling developers to interact with Lean using natural language, potentially democratizing formal verification for industries like aerospace, medical devices, and financial systems. The model is available for immediate use and represents Mistral’s continued commitment to open-source AI tooling for developers.

Pokémon Go Players Unknowingly Trained Delivery Robots With 30 Billion Images

Category: Autonomous Systems and Robotics Source: PopSci

Niantic Spatial has partnered with Coco Robotics to use data from Pokémon Go players to power autonomous delivery robots, revealing one of the most successful crowdsourced mapping efforts in history. Over 30 billion images captured by players hunting virtual creatures are now being used to help pink delivery bots navigate real-world streets with centimeter-level accuracy.

The Visual Positioning System (VPS) built from this data provides far more reliable localization than GPS, which often fails in urban canyons surrounded by tall buildings. By capturing the same locations from multiple angles, weather conditions, and times of day, Pokémon Go created a “living map” that updates continuously. While players have known Niantic was mapping the world, the revelation that their data now powers commercial robots delivering pizza has been met with surprising acceptance—many players appreciate that their contributions serve a practical purpose rather than something more dystopian. The system demonstrates how consumer AR applications can generate valuable training data for robotics at unprecedented scale.

Encyclopedia Britannica and Merriam-Webster Sue OpenAI Over Training Data

Category: Policy & Regulation Source: TechPuts

Encyclopedia Britannica and Merriam-Webster have filed a lawsuit against OpenAI, alleging the company used nearly 100,000 copyrighted articles to train ChatGPT without permission or compensation. The complaint argues that ChatGPT can produce “near-verbatim outputs” from Britannica content and that AI-generated answers are diverting traffic from the publishers’ platforms.

This case represents the latest front in the escalating legal battle over AI training data and fair use. Publishers argue that OpenAI “memorized and reproduced” their content rather than transforming it, while OpenAI maintains that training on publicly available data constitutes fair use. The “dictionary problem” at the heart of the case highlights a critical tension: foundational reference works are essential for training language models to understand meaning, but using them without permission may constitute infringement. The lawsuit joins similar actions from news organizations, authors, and music publishers globally, with courts’ decisions likely to reshape how AI companies source training data—potentially requiring licensing deals or fundamentally altering development practices.

Why Large Language Models Still Can’t Write Well

Category: Research Source: The Atlantic

Despite mastering technical tasks from protein folding to coding, large language models remain remarkably bad at creative writing—a puzzle that reveals fundamental constraints in their architecture. OpenAI CEO Sam Altman has acknowledged that even future GPT-6 or GPT-7 might produce only “a real poet’s okay poem,” and researchers explain why this limitation persists.

The problem stems from LLMs’ training process: models learn from vast quantities of mediocre internet text, then undergo post-training to become “helpful, honest, and harmless” teacher’s pets that always have the right answer. This optimization for correctness and consistency actively works against the risk-taking, surprising connections, and intentional ambiguity that define compelling prose. Early models like GPT-2 produced more creative (if erratic) outputs precisely because they lacked today’s safety guardrails and preference tuning. Modern LLMs overuse cloying metaphors, avoid biological imagery, and produce writing that lacks stakes—symptoms of training for compliance rather than creativity. Interestingly, functional programming languages like Elixir produce better AI-generated code than JavaScript precisely because their explicit semantics and immutable data structures match LLMs’ strengths in local pattern-matching rather than complex state management.
