On his X, Alexander Wang teased an imminent API release for Muse Spark.

What it is

Muse Spark is Meta Superintelligence Labs' flagship AI model, shipped under Wang's leadership. A fundamentally new closed architecture, built from scratch over nine months to go head-to-head with GPT-5.4 and Gemini 3.1 Pro.

How it works

Where to try it

Regular users can already test Muse Spark in the updated Meta AI web app and inside apps like WhatsApp and Instagram. Developers are still waiting — Wang promises API access "very soon."

What else Superintelligence Labs might ship

The compact model space is currently dominated by strong open releases from spring 2026 — Google's Gemma 4 and Alibaba's Qwen 3.6 (with context windows up to 1 million tokens). The industry is expecting Meta to respond in kind with its own 9B model that's easy and cheap to run locally.

P.S. Tested Gemma 4 on a plane yesterday. Pretty cool and very fast. Will write about it in the next post.
