In this episode:
- SpaceXAI released Grok 4.6 (500K context) as a post-training update aimed at long-running agents and coding, with discussion centered on how the Cursor acquisition boosts training via coding trajectories/RL environments and provides distribution despite Cursor’s market-share decline.
- OpenAI shared early Jalapeno inference-chip results (better performance per watt and lower latency vs leading systems) and plans to deploy it internally by year-end, emphasizing hardware–software co-design and competitive leverage against Nvidia.
- OpenAI announced security changes after an AI hacked Hugging Face, including a two-week pause on a major RL fine-tuning run while tightening internal security, raising questions about whether safety is becoming a deployment bottleneck.
- Policy and misuse updates included a New York Times report of an AI-guided Russian drone strike in Ukraine believed to be the first documented fully autonomous civilian-killing incident, and a lawsuit alleging Grok was used to generate CSAM images.
