Highlights from Rohan Paul's daily AI newsletter:
- OpenAI paused reinforcement learning training for two weeks after signs its upcoming Astra model reached "Critical" cybersecurity capabilities.
- Synthefy launched a foundation-model platform for structured numerical data — tables, transactions, sensor readings and time series — so every prediction problem no longer needs a separately trained model.
- Bloomberg published a piece on why Chinese citizens are far more optimistic about AI.
- Paper notes: "Mind Viruses: Self-Propagating Ideas in Multi-Agent LLM Systems", "AQuA: Recursively Self-Improving Quantitative Trading Research Agents", and "Small-Scale Experiments: Are They There Yet?".
- GLM-5.3 found a "potentially serious vulnerability" in Cursor.
- Bloomberg reports OpenAI's annualized revenue has topped a new threshold (truncated in source).
