Meta launched Muse Spark 1.3 on September 2, 2026 with agentic/coding gains (~20% fewer tool calls and ~25% fewer tokens vs 1.2). Alexandr Wang called it competitive with Claude Fable 5.1 and ahead of GPT-5.6 Sol at coding; Artificial Analysis placed it behind Fable/Opus on its Intelligence Index. 1.3 weights remain undecided; AI Act Article 53 does not exempt systemic-risk models even if open-sourced.
