APPLE'S ‘VERITAS' CHATBOT IS REPORTEDLY AN EMPLOYEE-ONLY TEST OF SIRI'S AI UPGRADES

An internal employee-only chatbot, codenamed “Veritas”, is speculated to be Apple's answer to ChatGPT, but it's unknown if or when it'll be released publicly. The company has struggled to get its AI efforts off the ground after a lukewarm reception to its Apple Intelligence features and multiple delays to Siri upgrades.

DEEPSEEK-V3.1-TERMINUS LAUNCHES WITH IMPROVED AGENTIC TOOL USE AND REDUCED LANGUAGE MIXING ERRORS

DeepSeek released V3.1-Terminus, which strengthens its Code Agent and Search Agent and addresses users' feedback about Chinese/English mix-ups. The model shows benchmark gains in agentic tool tasks (BrowseComp, SWE Verified, etc.) and offers both “chat” and “reasoner” modes for different use cases. Terminus remains open-weight under an MIT license, making it viable for customization and deployment both via API and local environments.

HEAD OF CHATGPT ADDRESSES CONTROVERSIAL MODEL ROUTING

OpenAI confirmed it's testing a safety system that automatically switches users from GPT-4o to reasoning models or GPT-5 when conversations touch on "sensitive and emotional topics." Users have complained that the routing triggers too frequently in harmless situations, pulling them away from GPT-4o, which many prefer for personal conversations.

THE AI VILLAGE IN NUMBERS

OpenAI's models lead on various stylistic measures like lexical diversity, positive sentiment, and formality of language, but Anthropic's models lead in goal-directed behavior. While OpenAI's models vary in which stylistic measures they excel at, Anthropic's models all perform well on agentic behavior. OpenAI offers the brightest, most cheerful, and most eloquent model. Anthropic's models tend to excel at getting stuff done.

OPENAI RELEASES WORKPLACE USAGE REPORT SHOWING RAPID CHATGPT ADOPTION

28% of US workers now use ChatGPT at work, with adoption highest among highly educated white collar workers in tech, finance, and manufacturing. It's vague exactly how the tool is being used - OpenAI is primarily for writing, research, programming, and data analysis - but technical teams have emerged as the clear power users.

MODULAR MANIFOLDS - THINKING MACHINES LAB

Normally, neural networks are trained by letting their weights move freely in any mathematical direction. A new method that restricts the weights to specific curved surfaces makes training more stable and predictable. This "manifold Muon" optimizer forces weight matrices to maintain consistent properties (like not stretching or shrinking data too dramatically) by constraining them to geometric shapes called manifolds. While promising, the experiments required computational overhead, which limits real-world adoption.

WE REVERSE-ENGINEERED FLASH ATTENTION 4

Flash Attention 4 is a brand new, highly optimized CUDA kernel that speeds up the attention calculations in transformers, which are the main mathematical operations that bottleneck AI models like ChatGPT. However, the improvements from FA4 are not from clever new math but from improvements in how an incredibly complex async pipeline splits computations across 32-thread ‘warps'.

WHAT PROBLEM IS DSPY SOLVING WITH WHAT ASSUMPTIONS

DSPY's programming model is a good base, but it has issues with defaults and missing affordances. This post identifies these issues and suggests some changes. Adopting these changes would sharpen DSPy's design without fighting it. It would keep the ergonomics that makes teams productive while aligning the optimization layer with the realities of fixed budgets and production constraints.

ALIBABA BETS BIG ON AI WITH NVIDIA TIE-UP, NEW DATA CENTER PLANS

Alibaba has partnered with Nvidia to enhance its cloud platform with advanced AI capabilities, focusing on robotics and autonomous driving. It plans to expand global data centers, opening facilities in Brazil, France, and the Netherlands to meet increasing AI infrastructure demand. The company also launched Qwen3-Max and Qwen3-Omni AI models, emphasizing improved performance in code generation and virtual reality applications.

EXPANDING OUR DATA ENGINE FOR PHYSICAL AI

Scale is expanding its Data Engine for Physical AI, providing robotics companies with high-quality, annotated datasets needed for training foundation models in physical environments. It addresses the robotics data gap by ensuring datasets are abundant, diverse, and enriched, collecting data through dedicated robots and human demonstrations. This aims to accelerate the development of reliable AI systems capable of handling real-world complexity in various applications.
