Transcript

I put Meta’s new Muse Wonder (and Wonder Full) frontier models through the How I AI bench, which covers nearly 20 tasks across prototyping, agentic workflows, coding, writing, and creative work. I scored everything with an LLM-as-a-judge pass and my own voice notes, then pulled together the first-look results you see here.

What you’ll learn:

Why Meta’s “personal and professional agent” framing mostly holds up, and where it doesn’t

What active focus mode actually does on long-running tasks, and whether it’s real

The three agentic tasks where Muse ranked first, and why those categories matter

What Muse’s design output actually looks like (it’s not good)

How it compares to Sonnet on voice assistant tasks

Where Muse lands on SVG and short-form video versus Opus 5.5, Astra, and Fable

Whether I’m actually putting Muse into any of my agent workflows
