• Company spokesperson says the API should be available in June.
• Developers who signed up for early access remain without a usable interface.
• Competitors like Microsoft, Google and Apple have already opened AI APIs.
• Muse Spark is Meta's first closed‑source model, limiting developer flexibility.
