In this episode of AI RADAR, we cover a major turning point: **Anthropic** halts the release of **Claude Mythos** due to severe zero-day hacking risks, launching Project Glasswing to harden global cyber infrastructure instead.

Next, **Meta** pivots from its open-weights ethos to launch **Muse Spark**, a closed multimodal reasoning model. We also cover Sierra's **Ghostwriter**, as Bret Taylor predicts the end of traditional SaaS software, replaced by autonomous AI agents.

Finally, quick hits on **Oracle's** new Fusion Agentic Applications and **OpenAI's** radical policy blueprint preparing the grid and economy for superintelligence.
