$META just went from 3.5% to 45.4% token share on OpenCode in just over two weeks Muse Spark 1.3 being good + free is enough to become the default for most users Default gets you usage → usage gets you data → data makes the next model better Anthropic and OpenAI can’t afford

My water heater is dying. I texted Muse the model number at lunch. It compared prices across three shops, emailed two installers for quotes, booked the Thursday job. I worked the counter all day. Came home to two quotes back and an install date. $1,450 beat $2,300.

Got Muse logged in to my medical provider’s portal, he pulled the itemized bills, and questioned every line. So far he’s found several times I’d been double billed, asked for some discounts and has saved me over $4,000. If your moat is bureaucracy, you’re cooked.

Muse built me a private library for the e-books and articles in my Google Drive. Everything is organized by topic, and each section opens onto its own subcategorized shelves. Each book opens like a real book and is readable in-app

I still can’t believe I can run my plumbing company with an agent so easily. I send this message to my Muse agent while in bed at 6am. And it: updates my job board, texts customer, updates office manager who arrives at 8am in slack Notifies technician
