Meta’s Muse Spark 1.1 outperforms GLM-5.2 in coding and costs slightly less

What happened

Meta released an update to its Muse Spark AI model, version 1.1, which outperforms GLM-5.2 in coding tasks while costing slightly less per task. On the Artificial Analysis Intelligence Index, Muse Spark 1.1 scored 51, up eight points over the past three months. In coding benchmarks, it achieved a score of 71.3, edging ahead of GLM-5.2. The cost to run tasks dropped to about 26 cents each, while the hallucination rate fell sharply from 73 to 38 percent.

Why it matters

For builders and businesses relying on AI-powered code generation, Muse Spark 1.1 boosts efficiency both in performance and cost. Scoring higher in coding accuracy means fewer developer hours spent fixing errors or debugging AI-generated code. The reduced hallucination rate signals improved reliability, lowering operational risks where AI might produce incorrect or misleading outputs. At a lower price point, Muse Spark 1.1 exerts downward pressure on unit costs for AI-assisted development tools and services. This combination tightens competition among AI model providers aiming at software automation, potentially accelerating adoption by startups and enterprises managing budgets closely.

What to watch next

Keep an eye on how Meta continues to optimize Muse Spark for coding and other niches. If this trend continues, cost improvements paired with better accuracy could sway more development platforms to integrate Meta’s models. Also monitor how GLM and other rivals respond, especially regarding pricing and hallucination reduction. The broader market will be watching for vendor lock-in shifts as more players push similar AI capabilities at competitive pricing. Effectiveness plus affordability will shape which models become standard infrastructure in developer workflows over the next year.
