We were able to fine tune an open weight model (Qwen3.5-9B) on proprietary internal data at @coinbase, and it out performed frontier models, at much lower cost and speed, for a specialized task (fraud prevention in this case).
I think we'll see more of this pattern inside companies. The frontier models are amazing generalists. But increasingly you'll see specialist models out perform on more narrow tasks, either working on teams, or by themselves.
We're making it easy to fine tune models internally for our employees. We even have a skill for it in our internal harness that makes it easy to spin these up and start training them:
"/fine-tune-and-serve-llm I want to fine-tune Qwen for payments risk review. help me get started"
I imagine we'll have some backend services that could be replaced entirely by this new architecture.

Instinct in group chats
Starting today, early access users can add Instinct to group chats. A new Instinct joins and works for the whole group.
Making plans with friends usually turns into a frustrating back-and-forth over times and places. With Instinct in the group, you can explore options together, agree on a plan and get it done, all in one thread. Your friends don't even need Instinct to join in.
A few things it’s good at:
- Planning a weekend trip with friends, including dates and arrival times
- Coordinating logistics with a roommate
- Getting tickets as soon as they go on sale, then splitting the cost and sending one to everyone
- Running a fantasy league, keeping standings, settling rules disputes, and reminding everyone to set their lineups
- Sorting out carpool schedules - works out who’s driving each day from everyone’s schedules
- Organizing Thanksgiving, keeping track of who’s bringing what and ordering the shopping list
Group chats are new territory for Instinct, and we put a lot of care into getting the permissions right. Here’s how it works:
- Your personal Instinct asks before connecting with the group’s Instinct. You choose which groups to trust and can remove trust at any time.
- The group’s Instinct has no direct access to your personal accounts. Your Instinct checks your permissions before sharing information or taking action.
- If someone new joins the group, all pending replies from your Instinct are held until you grant it permission to share with the expanded group.
Group chats are available to all of our early access users, and will be rolling out to everyone soon. To join early access for this release, ask your Instinct to put you on the list.
Great work with @GajanNagaraj @anuda_w and @saagarwashere
I’m building Carried Health (carried.health) to help patients organize medical records and prepare for appointments.We’ve submitted an NSF SBIR Phase I proposal to study how AI handles incomplete and conflicting records. Separately, I’m helping organize a rare-disease research program (f4808n.com). If you work in these areas, I’d like to hear from you.
Today was my last day at Shopify.
I learned a ton during my time there, and I’m thankful for the people I got to work with. Thank you for sharing your ideas, your time, and your support.
Taking a little time to decompress. And using the extra time to keep building.
One of the reasons I work at Shopify.

This feels so right to me.

So you need to divide your PRD in 4 sections: Table stakes, Differentiators, Delighters, and Hero Features.
Lovable products go beyond the obvious and delight customers.
Elon Musk: "If you punish people too much for failure, then they will respond accordingly, and the innovation you will get will be very incrementalist
Nobody's gonna try anything bold for fear of getting fired or being punished in some way. So risk-reward must be balanced and favor taking bold moves, otherwise it will not happen"

Several hundred U.S. Special Operations Forces, including Army Rangers and Navy SEALs, have arrived in the Middle East, joining thousands of Marines and Army Paratroopers from the 82nd Airborne Division in a deployment meant to give President Trump additional options to expand the current monthlong Iran War, with planning underway for possible ground operations, two U.S. military officials have told The New York Times.

If you can’t call out antisemitism clearly, you are part of the problem.
Canada is drifting.
And now the world is noticing.
“More synagogues… desecrated, burned, shot at… than in any other country.”
“We’re witnessing a polite pogrom.”
Read that again.
That should stop us in our tracks.

Chances that normal shipping traffic returns to the Strait of Hormuz by the end of April has plummeted in the last 48 hours, down over 30% currently sitting at around 44%, following a number of strikes by Iran on cargo vessels and oil tankers near the Strait, as well as an attack overnight on two tankers off the coast of Iraq.

This was really fun. Thanks for having me @JacobShap
A different kind of episode…one of my best friends landed in Tel Aviv less than 24 hours before the rockets started falling. Here’s the story of how he escaped….and what snacks are like on emergency DHS evacuation flights.

Our newly launched @joinkudos AI agent called T-Mobile and cut my bill by $840/year (54%).
It handled the hold music, the bots, and the negotiation.
Companies have call center AI agents. Now consumers have theirs too.
Here’s the clip of the call.
When everyone else goes Mac Mini, I go Reachy mini. Trying @openclaw on reachy mini tonight!
Hey @bcherny, I'm super excited about Claude Cowork and I love to have multi-user collab to work on projects with my wife or team at work. Any plans to add shared access soon? Would be a game-changer!
