GLM-5.3-Flash vs Qwen3.8 Flash-Next:
Both on 2× DGX Spark, same 80-test Spark-Bench:
-GLM 84.8
-Qwen 79.4 (vLLM) / 77.9 (TensorFold)
GLM wins most categories. The biggest gap is long context. Where each one wins
• Long context: 70.8 vs 21.6–27.9. GLM found the planted fact on the hard needle test, Qwen missed it on both engines.
• Code: 90.2 vs 85.7–87.1
• Visual: 79.8 vs 71.4–75.0
• Tool use: 78.2 vs 58.2–75.6
• Agentic: 78.5 vs 67.1–75.1
Takeaway: Qwen follows instructions and formats more precisely. GLM is the stronger generalist: it codes, builds and retrieves better.
