Meta ships Muse Spark 1.3 with max reasoning, pitching frontier performance at non-frontier prices
AIatMeta · x · 2026-09-05
Meta announced that Muse Spark 1.3 with max reasoning is now available on Muse Code and the Meta Model API, pitching frontier-level performance without frontier pricing.
To show rather than tell, teams in Meta Superintelligence Labs built demos with a single one-shot prompt: build a rendering engine from scratch in C that writes pixels directly, scales from simple primitives to complex scenes, and ends in a striking lighting demo. More demos are in the series.
