Covered in this episode: - Infinity raises $15 million at a $100 million valuation to build software that helps AI chips run models more easily across different hardware. - The Financial Times reports that AI deepfakes are raising the risk of “synthetic insider” attacks and changing how companies handle hiring and internal security. - New arXiv research finds that evidence-sufficiency prompting in clinical LLMs can look safer depending on which judge scores the result, with model-specific helpfulness tradeoffs. - A Forbes piece on an AI agent showing self-reflection about its own limitations. - OpenAI shares lessons from deploying long-running models, including new risks, observed failures, and safeguards. - Simon Willison highlights Ben Thompson’s proposal on training-data fair use, distillation, and competition with Chinese open models.
