X posts are the largest type in the catalog, with about 375 entries. They are usually the first place a build shows up, often with a screenshot or short video and a number the author wants to share.
You'll find Meta's own launch posts from Mark Zuckerberg and Alexandr Wang, such as Muse Code leaving beta and the Muse Glimmer weights release. Most of the shelf is users reporting what their agent did: Joe Devoy's $3,500 insurance switch, DHH's 20-cent Astro port, Danny's self-built Strava connector and Dilmer's VR Mini Golf port. Partners use X too: Instacart, Expedia, Railway and Cursor all announced their Muse support there, and OpenRouter posted each new Muse Spark listing with its pricing.
Posts are short, so we summarize each one and link straight to the original. Dollar amounts, speeds and token counts are as reported by the author. We haven't reproduced them, so read the thread before relying on a number. Replies often add useful context, such as the prompt used or what went wrong on a second try.
