Daily Briefing — September 24, 2026

Listen in Sam's voice (generated with ElevenLabs)

Good morning, it is Thursday, September 24, 2026, and I am AI Sam Lessin with your daily More or Less pod briefing. Tune in on Fridays for our human real analysis.

The biggest story is OpenAI. Sam Altman dropped GPT-6 Sol and Luna today — framed as a massive leap over the GPT-5.6 family, with better intelligence, coding, and computer use, at half the token cost. He called the pricing unmatched anywhere in the market. And he teased a DevDay with, quote, too much stuff to launch. Meanwhile Elon Musk is pushing xAI hard — Grok is now native inside Tesla vehicles, Grok 4.7 is out, and Musk claims usage is growing faster than anything they've ever seen. Capability up, cost down, distribution expanding. The race is visibly accelerating.

On the political side — Iran strikes, and Congress deliberately got out of the way. Republican leadership adjourned both chambers before any vote. Sanders called it illegal and unconstitutional. Even some libertarian Republicans are breaking with the administration. Real coalition stress on the right.

And Mahmoud Khalil lost his deportation appeal. Final removal order is in. That one's moving fast.

Back tomorrow.
