- Meta has released a new frontier-level model, Muse Spark 1.3, officially pitched by Alexandr Wang as frontier performance at a fraction of the cost.
- It ranked #8 on the third-party Landing Page leaderboard with a 42.3% win rate, just behind Gemini 3.6 Flash and ahead of DeepSeek V4 Flash.
- In a Human Creativity Benchmark across Ideation → Mockup → Refinement, compared against Claude Fable 5.1, GPT-5.6 Sol, and Kimi K3, its standout strength is turning an existing creative direction into a high-quality finished product at extremely low cost — potentially reshaping the economics of coding agents.
