Qwen 3.8 Max (Fully Tested): AN ACTUAL OPEN FABLE COMPETITOR!
In this video, I'll be testing the new Qwen 3.8 Max Preview, a massive 2.4 trillion parameter model that Qwen has confirmed will be open-weight. I’ll run it through my full KingBench benchmark, compare it against models like Fable 5, Opus 4.8, Kimi K3, GLM-5.2, and GPT-5.6 Sol, and share my real experience using it with Claude Code. -- Key Takeaways: 🚀 Qwen has announced Qwen 3.8, a massive 2.4 trillion parameter model with confirmed open weights. ⚡ Qwen 3.8 Max Preview is already available through the Token Plan, Qoder, and QoderWork. 📊 On KingBench, Qwen 3.8 Max scored 65 out of 80, landing in second place overall. 🏆 It finished just behind Fable 5 and above Opus 4.8 on the full benchmark leaderboard. 🎯 The model performed extremely well on frontend, Three.js, SVG, game, math, and agentic tasks. 🧠 Qwen 3.8 Max got perfect scores on the bow and arrow game, the hard math problem, and the long-horizon agentic task. 🛠️ In Claude Code, the model felt fast and capable, though it may still struggle a bit with longer-running tasks. 🌍 With open weights confirmed, Qwen 3.8 could become a major model for the open-source AI community.
