In just three months, the model gained eight points, mostly in coding and agent-based knowledge work. On [the Coding Index](https://x.com/ArtificialAnlys/status/2075677419495940328), it scores 71.3, ahead of [GLM 5.2 (68.8)](https://the-decoder.com/zhipu-ais-glm-5-2-closes-in-on-closed-source-leaders-in-coding-marathons/) and barely behind [GPT-5.6 Luna](https://the-decoder.com/openais-claude-mythos-competitor-gpt-5-6-sol-launches-under-government-controlled-access-it-calls-unsustainable/) (71.4). The top spots belong to GPT-5.6 Sol (77.4) and Terra (76.7), followed by Claude Fable 5 (76.5). As always, benchmark scores don't always match real-world performance.\n\nMuse Spark 1.1 costs an estimated $0.26 per task, compared to $0.37 for GLM-5.2 and $0.89 for GPT-5.4, while using only 94 million output tokens (GLM-5.2 uses 141 million). The hallucination rate dropped from 73 to 38 percent: the model now more often declines to answer rather than giving wrong ones. Meta also quadrupled the context window to one million tokens. At launch, [Muse Spark 1.1 is available only through Meta's own API](https://the-decoder.com/metas-muse-spark-1-1-api-pricing-squeezes-openai-and-anthropic-as-the-ai-price-war-heats-up/).\n\n```\nAI News Without the Hype – Curated by Humans\n\n\t\t\t\t\tSubscribe to THE DECODER for ad-free reading, a weekly AI newsletter, our exclusive \"AI Radar\" frontier report six times a year, full archive access, and access to our comment section.\t\t\t\t\n\n\t\t\t\t\tSubscribe now\n```\n\n[Artificial Analysis via X](https://x.com/ArtificialAnlys/status/2075677416295739660)", "url": "https://wpnews.pro/news/meta-s-muse-spark-1-1-outperforms-glm-5-2-in-coding-and-costs-slightly-less", "canonical_source": "https://the-decoder.com/metas-muse-spark-1-1-outperforms-glm-5-2-in-coding-and-costs-slightly-less/", "published_at": "2026-07-11 08:28:12+00:00", "updated_at": "2026-07-11 08:37:26.940812+00:00", "lang": "en", "topics": ["artificial-intelligence", "large-language-models", "ai-products", "ai-infrastructure"], "entities": ["Meta", "Muse Spark 1.1", "GLM-5.2", "Artificial Analysis", "GPT-5.4", "GPT-5.6 Luna", "GPT-5.6 Sol", "Claude Fable 5"], "alternates": {"html": "https://wpnews.pro/news/meta-s-muse-spark-1-1-outperforms-glm-5-2-in-coding-and-costs-slightly-less", "markdown": "https://wpnews.pro/news/meta-s-muse-spark-1-1-outperforms-glm-5-2-in-coding-and-costs-slightly-less.md", "text": "https://wpnews.pro/news/meta-s-muse-spark-1-1-outperforms-glm-5-2-in-coding-and-costs-slightly-less.txt", "jsonld": "https://wpnews.pro/news/meta-s-muse-spark-1-1-outperforms-glm-5-2-in-coding-and-costs-slightly-less.jsonld"}}
