In this episode:

• Anthropic cut off access to Fable 5 and Mythos 5 after a US government order tied to alleged jailbreaks, prompting debate over inconsistent policy, export controls, and the practicality of preventing jailbreaks.
• SpaceX completed an IPO at a roughly $1.75T valuation and then moved to acquire AI coding startup Cursor for $60B, positioning xAI with Cursor’s talent, data, and product to compete more effectively in coding.
• Infrastructure and business updates include Anthropic pursuing direct US data center leases backed by Google, leaked documents showing OpenAI’s revenue growth alongside large losses, and chatbot market share shifting with ChatGPT below 50% as Gemini and Claude gain.
• Projects and policy highlights include OpenRouter’s Fusion multi-model synthesis, new open releases from Moonshot, Qwen, and NVIDIA, DOJ support for xAI’s unpermitted gas turbines in Memphis, and a Munich court ruling Google liable for false AI Overview statements.
