What happened
Claire Vo reviewed Meta's newly launched Muse Wonder and Muse Wonderful frontier models on the How I AI bench, running them headlessly through Claude Code across nearly 20 tasks covering prototyping, agentic workflows, coding, writing, and creative work. She reports Meta's 'personal and professional agent' framing mostly holds up, with Muse ranking first in three agentic tasks, but design output is not good and it is slow on agent tasks despite being fast on one-shot work. The piece also compares Muse to Sonnet on voice assistant tasks and to Opus 5.5, Astra, and Fable on SVG and short-form video.
Why it matters
If you are choosing models for agent workflows, this suggests Muse Wonder may be worth testing for three agentic task categories, but not as a default for design, SVG, or short-form video work; it also warns that agent tasks may be slower even when one-shot prompts feel fast. Treat it as a first-look signal to run your own eval rather than a settled benchmark, since the excerpt gives no exact scores.
Discussion angle
Ask everyone to name one agent task they would actually run Muse Wonder against and one task where they would still default to another model, using Claire Vo's split between strong agentic results and weak design output as the prompt.
