GLM 5.1 Just Dropped **FULLY TESTED in Claude Code**

GLM 5.1 just dropped and people are freaking out - it's VERY slow but to be quite honest with you the design ability + the coding ability was about the same as a test I did with Opus 4.6 yesterday GLM 5.1 just dropped and I put it through a real coding test — building a full Astro website with the Astro Builder skill inside Claude Code. The result? Eerily similar to what Opus 4.6 built yesterday. The catch? It's painfully slow. Like, 90 minutes slow. But the quality is legit. In this video I test GLM 5.1's actual coding ability (not benchmarks) by having it build a complete SEO-optimized website with Turso database, contact forms, admin dashboard, and blog — all from one prompt. I also compare the output side-by-side with a Claude Opus 4.6 build from the day before. Spoiler: the design quality is shockingly close. If Z.AI fix the speed issues before the full release on April 6-7, this could be one of the best coding models available.
