Growth CEO’s AI Briefing
October 2026
21 editions
Keep Control
This week's thread is control: over where your models run, what your cloud bill commits you to, who owns the customer relationship, and which skills your team keeps.
Show the Return
AI spend is turning from an experiment into a line item, and this week the tools to measure and steer it arrived alongside the next model race.
Test It Yourself
This week's lesson: test AI on your own work before you trust anyone's numbers, including the vendors'.
Scale the Checks
AI output got cheaper and faster again; the winners are scaling their checks just as fast.
Read the Fine Print
This weekend's filings and incidents share one lesson: read the terms behind the headline before you act.
Gate the Agents
This week's agent story shifted from what agents can do to who lets them in, and on what terms.
Rotate the Keys
Yesterday was a reminder that the plumbing under your AI plans is now both the main risk and the main bargain.
Watch the Agents
Agents are doing more on their own, and today's reading is about the controls that have to come with them.
Check the Locks
Today's reading is about locks. Criminals are pointing cheap agents at ordinary security gaps, Washington is policing which models sit inside the software it buys, and the companies running agents well are writing permission rules into code.
Check the Work
The weekend's reading points to one discipline: check the work, not just the result.
Read the Bill
Today's reading keeps returning to one question: who pays for AI, and does anyone understand the bill?
Check the Plumbing
Today's best reading points to the unglamorous layer under every AI program: tracking, routing, review and sandboxes.
Show the Receipts
Today's best reading shares one instruction: look past the impressive number to the receipt behind it.
Crowded Frontier
Two new frontier models arrived in two days, both priced to match the leader rather than undercut it.
Contain the Agent
Today covers the 72 hours since Friday's edition, and the weekend's news converged on one question: how much freedom to give AI agents, and how to take it back.
Work, not Answers
This week's launches point one way: AI tools are being sold as finished work, with the controls and the bill attached.
Rent or Route
Model prices fell again this week, and two companies showed opposite responses: commit to one vendor's stack, or route across all of them.
Easier to Switch
Three developments this week make it easier to change AI suppliers, and two pieces explain why that option matters.
Check the Fine Print
Today’s stories reward a careful reader: in nearly every case, the limits sit in the fine print.
The Meter Is Running
The weekend's reading points one way: the free phase of the agent build-out is ending, and everyone is starting to count.
Control and Choice
Seven items today, covering two days because no edition went out Thursday.
