CSProfKGD · x · 2026-09-03

Meta has released Muse Spark 1.3, which the company calls its biggest jump yet on coding and agentic work, with major gains in long-horizon tasks and visual coding. It remains very cheap — "frontier performance almost too cheap to meter" — and is live in Muse Code and the Meta Model API. Open-weights releases and a model codenamed 🍉 are teased next.
