Episode notes

Today’s show:

Cerebras just jacked its IPO range to $150–$160 a share, OpenAI bought a consulting firm to seed its $4 billion private-equity joint venture, and a startup in Oakland is electrolyzing magnesium out of seawater for one-third the going price. Alex Wilhelm and Jason Calacanis go deep with AI21 co-CEO Ori Goshen on why model orchestration, not bigger LLMs, will decide who wins enterprise AI.

The crew also covered the decline of OpenClaw, TikTok's new £3.99 ad-free tier, more entries in the live-show sidebar bounty, and had time for a little Off Duty before signing off.
