Why older availability pages can mislead

Muse Code launched after earlier Muse Spark and Meta Model API previews. A page describing an older developer preview may be accurate for its date and still be the wrong answer for current Muse Code access. Check the product name, model version, publication date, and whether the page is official.

If you cannot access the beta

Start at Meta’s current Muse Code product page. Confirm the intended account, platform, and region. If the installer is reachable but authentication is not, preserve the exact error rather than deleting local credentials. Beta capacity, staged rollout, and account eligibility are separate from a broken shell command.

Use the installation guide for the verified command and troubleshooting for safe diagnostics. Return to getting started once access is confirmed.
