Meta is reportedly delaying the release of its upcoming Muse Spark AI model API to developers, with no confirmed launch date as of Tuesday, according to reporting cited by multiple outlets. The Wall Street Journal says Meta has repeatedly pushed back the developer rollout of the internally named “Muse Spark,” raising questions about timing and readiness. Reuters, also cited in one summary, reports that a Meta spokesperson says the company is already testing the API with selected early partners and intends to release it this month. Meta AI Chief Alexandr Wang previously indicated on X in April that the “muse spark API will be coming soon.”

Meta unveiled Muse Spark in April, describing it as the first model in a new series built by its Superintelligence Labs. Other coverage notes that Meta has also announced an AI agent aimed at helping businesses handle routine operations, signaling efforts to broaden its AI offerings while competing with companies such as OpenAI, Anthropic, and Google.
