A First Look at Meta Muse Wonder on Agent and Design Tasks

In this October 2026 first look, Claire Vo tests Meta’s Muse Wonder model on her own How I AI tasks. Her rankings combine an LLM judge with her personal assessment and should be read as a small, subjective evaluation rather than a universal leaderboard.

Vo summarizes Meta’s claims about agentic work, coding, memory and sustained effort. She treats these as the company’s stated positioning before comparing them with her own observations.

For the test, Vo obtained access to Muse Code and ran it headlessly through another coding agent. She says she did not thoroughly evaluate the Muse Code interface itself, so the results concern this particular setup.

Her benchmark includes nearly 20 tasks across prototypes, coding, writing, agent workflows and creative work. An LLM judge and Vo’s voice-note assessments both contribute to the review; task selection and judging methods can affect the rankings.

Vo says the model performed well on her agentic tasks and adequately on two coding tasks. She was less satisfied with design and some creative outputs. These are first impressions from a limited set of examples.

One test asks an agent to resolve a complicated billing ticket in an administrative app, including an account mismatch, a duplicate and a prompt-injection challenge. Vo reports that the model handled the planted issues in her run.

She liked the model’s concise emails and conversational assistant tone for her own use. That preference is subjective and does not establish that generated messages are always correct or suitable to send without review.

For product-requirements documents and interface prototypes, Vo found missing detail, nonworking elements and design choices she disliked. She says she would continue testing before drawing broader conclusions about coding.

The SVG illustrations were usable in her view but ranked below several alternatives in her selected comparison. The short-video test found an acceptable passage, while she disliked its visual overlays and audio.

Vo reports quick responses on some one-shot tasks and longer runtimes on agentic work. She speculates that a sustained-effort mode may play a role but says she needs more measurement.

Her tentative conclusion is to try the model in agent workflows while continuing to use other tools for design. The video records one reviewer’s preference at a particular point in time.
