We also look at a new Nature article on safety and security challenges for healthcare language models, plus brief updates from SpaceX, Anthropic, and the developer-tooling world.\nCovered stories:\n- OpenAI pauses parts of frontier reinforcement-learning training while hardening cyber safeguards\n- OpenAI previews Private Safety Processing alongside Zero Data Retention for eligible API customers\n- Nature article: safety and security of large language models in healthcare\n- Cognition CEO denies a report that SpaceX sought to acquire the AI coding startup\n- Report says Anthropic is using an unpublished internal model called Model 2\n- smolvm sandbox testing for untrusted Python and JavaScript\n- A case for LLM-assisted extensible software with sandboxed plug-ins\nSources:\n- OpenAI, “Pacing model development in an era of cyber-critical capabilities”: https://openai.com/index/pacing-model-development-cyber-capabilities\n- OpenAI, “Offering Zero Data Retention for frontier models”: https://openai.com/index/offering-zero-data-retention-for-frontier-models\n- Nature, “Safety and security of large language models in healthcare”: https://www.nature.com/articles/s41586-026-10687-1\n- TechCrunch, “Cognition CEO denies report that SpaceX tried to acquire the startup”: https://techcrunch.com/2026/08/19/cognition-ceo-denies-report-that-spacex-tried-to-acquire-the-startup/\n- The Decoder, “Anthropic uses an unpublished AI model called Model 2 internally”: https://the-decoder.com/anthropic-uses-an-unpublished-ai-model-called-model-2-internally/\n- Simon Willison on smolmachines and smolvm: https://simonwillison.net/2026/Aug/19/smolmachines-untrusted-sandbox/\n- Simon Willison quoting Jeremy Morrell on extensible software: https://simonwillison.net/2026/Aug/19/jeremy-morrell/","thumbnail_url":"https://img.transistorcdn.com/U8MjYsqEAUXr8sykSIjiubn3kUnZpkcAAqCjELTLubA/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS85YWE0/MDRlYTJkZTY4ZDhk/N2YzZjZmYzg0ZmQ2/Mzg1NC5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
