AI-summarised brief · reviewed before publication

AI models cost more to develop than expected, with final training runs accounting for only a small fraction of total costs. Epoch AI found that OpenAI spent only 10% of its $5 billion R&D budget on training runs, with most going to scaling and research. Similar patterns were seen in Chinese companies MiniMax and Z.ai, sparking concerns about intellectual property theft and replication of results at a lower cost.

Nearly half of American adults now use AI, but concerns are also…

New research by the Pew Research Center reveals that nearly half of American adults (49%) now use AI chatbots, such as ChatGPT or Gemini, marking a significant increase from last year's 33%. Americans are using AI for various tasks, including researching information, handling work tasks, and entertainment. ChatGPT dominates the U.S. AI market, with 44% of respondents using the OpenAI chatbot. However, concerns about AI's impact on society and data security remain high, with 40% believing AI will be more harmful than beneficial and 71% expecting AI to make their personal information less secure.

💡 Growing AI adoption raises questions about accountability and regulation, as Americans lack confidence in both the government and AI companies to develop and use these tools responsibly. The widespread skepticism about AI's impact on society highlights the need for more transparent and effective regulation to address concerns about data security and societal benefits.

Apple’s AI agents in Xcode 27 make vibe coding easier

Apple has unveiled Xcode 27, a developer tool that integrates artificial intelligence (AI) to simplify the coding process. The new version of Xcode includes a Core AI framework that allows developers to use on-device AI models with ease, delivering strong performance through a modern Swift API. Xcode 27 also supports third-party AI models and enables developers to have conversations with AI agents, making it easier to create and edit code. This marks a significant shift in Apple's approach to AI, positioning it as a powerful extension of the coding process.

💡 Apple's emphasis on AI in Xcode 27 raises questions about the future of human interaction in app development. By portraying AI as a tool to augment human capabilities, rather than replace them, Apple may be trying to alleviate concerns about job displacement. However, the company's decision to showcase AI-generated apps and code may ultimately lead to a surge in "vibe-coded" apps, challenging the notion that human touch is essential in app development.

Satellite AI Inference Clears Orbit: Gemma 3 Ran Aboard YAM-9 in April

Loft Orbital's YAM-9 spacecraft successfully demonstrated the first publicly disclosed execution of a vision-language model in orbit. Aboard the spacecraft, Google DeepMind's Gemma 3 performed natural language queries, classified Earth imagery, and produced plain-English summaries without transmitting raw pixels to the ground. This achievement marks a significant shift in the value layer of Earth observation, moving from ground-based processing to onboard inference capabilities. The model, running on an Nvidia Jetson Orin AGX graphics processing unit, utilized a software harness developed by NASA's Jet Propulsion Laboratory to fit within the spacecraft's memory budget and processing constraints.

💡 This breakthrough enables Earth observation satellites to operate more autonomously, reducing reliance on ground-based processing and potentially leading to faster and more efficient analysis of satellite imagery.
