Meta launched Muse Wonder

Meta announced Muse Wonder, a new family of frontier models built for personal and professional agent work. Alexandr Wang says it adds "active memory," so Muse can remember what you told it days or weeks ago and use that on future tasks.

On Cheeky Pint with John Collison, Wang said Muse is "one of the first products where people are fully delegating purchases to the agents." Zuck added that "every business is going to have agents too."

AI Assistants Rank on 14-Day Retention

Muse's D14 retention numbers last week were shared, and they're close to ChatGPT's, sitting at 22.5% compared to ChatGPT’s 26.8%.

I personally messaged dozens of iMessage based AI-assistant founders to get a better grasp of what the general industry D14 stats are looking like. Self-reported numbers ranged from ~20% to a handful that independently reported sitting between 40-50%.

One remaining question: what defines retention rates for iMessage-based apps?

AI Assistant Consumer Travel Report

This report tested five AI assistants on booking travel: Instinct, Muse, GrokBot, Dots and Miso. Each was scored on eight areas, from booking time and seat selection to cancellation and rebooking.

All five booked a flight, but only some could change one afterward. Miso won the battle, with Instinct coming in at a close second.

Grok Bot, Dots & Muse struggled in their own ways while being painfully slow.


AI Assistant Competition Updates


The Agentic Economy

Elon Musk:

He hit back at Amazon after reports that it's blocking Grok's shopping agents. He floated the idea of building a company to compete against Amazon in this world of agentic commerce.

Shopify's Tobi Lütke:

He introduced shop.md, a plain file that tells AI agents what a store sells and how they can buy from it.

JPMorgan (via CNBC):

America's biggest bank has officially blocked companies like Instinct and Muse from accessing Chase accounts via browser-use.

“We’re not going to allow [it]…it’s just too risky for clients and for JPMorgan.”

Google:

Google launched Universal Cart in Search and the Gemini app, letting people check out across many stores in one cart, which is the same kind of buying an agent would do for you.
