Overview
- Muse Spark launched in April as the first major model from Meta Superintelligence Labs but has been kept mainly inside Meta products.
- Reports in early June say Meta has repeatedly pushed back the public developer launch of the Muse Spark API because of persistent software bugs and infrastructure problems.
- Meta tells partners the API is in limited partner testing and says it intends to make the API available later this month, though no firm date has been disclosed.
- Chief AI Officer Alexandr Wang says Muse Spark is strongest on visual and health reasoning and that Meta plans to build health advice features into Instagram, WhatsApp and Facebook.
- The delays matter because Muse Spark is closed-source and Meta is banking on paid API access to turn its multibillion-dollar AI investments into revenue while rivals accelerate and regulators watch safety and biological‑risk issues.
