Max and AI expert Rayan Kovarik unpack a big week in AI. They explain the shift from pretraining to post‑training (instruction tuning, RLHF/RLAIF, preference modeling, and tool use) and why this “coaching” phase drives safety and usefulness. They dive into AWORLD, a distributed framework that speeds agent experience generation by 14.6x and boosts GAIA benchmark results using a Qwen3‑32B base. OpenAI’s ChatGPT gains full MCP write support, turning conversations into secure, auditable actions across enterprise tools. A hands‑on tutorial shows multi‑agent coordination with coordinator/researcher/analyzer/executor roles in a notebook‑friendly setup. The duo demystifies federated learning’s real‑world challenges and why software and optimization matter as much as theory. Microsoft reportedly brings Anthropic’s Claude into 365 for pragmatic, best‑fit AI features. TwinMind raises funding for an on‑device, privacy‑first “second brain” that transcribes all day, fuses offline and browser context, and answers personal queries. Leonardo accelerates Nordic cybersecurity acquisitions to advance a Zero Trust, European digital autonomy strategy amid the AI‑driven attack surface. They close with the robotics and AV frontier: simulation, sensors, and control systems that steadily bring intelligence into motion. Three takeaways: skill beats size, orchestration is the new UI, and trust is the backbone of AI deployments.
