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

Meta's Muse Spark 1.1 model outperforms GLM-5.2 in coding benchmarks and costs less per task, according to Artificial Analysis. The model scores 71.3 on the Coding Index versus GLM-5.2's 68.8, with a price of $0.26 per task compared to $0.37, while also reducing hallucination rates and quadrupling context window to one million tokens.

Meta's Muse Spark 1.1 outperforms GLM-5.2 in coding and costs slightly less Meta's new Muse Spark 1.1 model edges ahead of GLM 5.2 in coding while coming in at a lower price point. According to Artificial Analysis https://x.com/ArtificialAnlys/status/2075677416295739660 , it scores 51 on the Intelligence Index, tying with GLM 5.2, GPT-5.4, and GPT-5.6 Luna. 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. Muse 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.
