Muse Spark 1.3 Max by @AIatMeta has reshaped the Pareto frontier for Code Arena: WebDev! Meta's latest model at Max reasoning is doing something interesting on the Arena Pareto frontier: it's the only model holding down the wide price band between Qwen3.8-max ($5/MToken) and Qwen3.8-Flash-Next ($0.39/MToken). The next closest model to the frontier is Meta's own, Muse Spark 1.3 on xHigh reasoning. Muse Spark 1.3 Max performs just 20 pts lower than Qwen3.8 (Max) while costing 30% less, and 24 pts from Kimi K3 (Max) while costing 70% less. - Muse Spark 1.3 Max: 1650 pts | $3.50/M - Qwen3.8 (Max): 1670 pts | $5/M - Kimi K3 (Max): 1674 pts | $12/M Overall in Code Arena: WebDev, Muse Spark 1.3 Max landed #8 , ahead of Claude Fable 5 at #10 (+22 pts), Grok-4.6 (High) at #12 (+26 pts), and GPT-5.6 Sol at #14 (+33 pts). Congrats to the @AIatMeta team on this release! Arena.ai @arena Muse Spark 1.3 (xHigh) just landed @AIatMeta back in the top 10 models for Code Arena: WebDev! This release is ~ #10 in Code Arena: WebDev with 1623 pts (AutoEval). It’s performance is par with Claude Fable 5 at #8 (1628 pts) and GPT-5.6 Sol at #11 (1616 pts). Muse Spark 1.3 (xHigh) is a huge improvement from previous models Muse Spark 1.1 at #25 (1540 pts), and Muse Spark 1.2 (xHigh) at #30 (1534 pts). Note: this is an early AutoEval score, in which a Reward Model trained on Arena’s human preference data casts automatic votes in place of live votes. We’ll continue to see how scores converge as more live human votes come in. Congrats to @alexandr_wang and the @AIatMeta team on this release! 🔗 View Quoted Tweet 💬 5 🔄 4 ❤️ 50 👀 6688 📊 9 ⚡
