What is Meta's Muse Spark?

Meta's first model from Superintelligence Labs—a multimodal reasoner with Instant, Thinking, and Contemplating modes for vision, STEM, health tasks. Claims 10x compute efficiency over priors.

Is Muse Spark better than GPT-5.4?

Beats it narrow—CharXiv vision at 86.4 vs. lower. Trails overall benchmarks. Real edge: cheaper runs, agent orchestration.

Can Muse Spark replace Claude for developers?

Not yet—no open weights, gated access. Strong on visuals, weaker code. Watch for API drops.
