GLM 5.2 vs Claude Opus 4.8 (and Kimi K2.7): Side-by-Side Coding & Game Tests + BenchmarksThe video compares GLM 5.2 against Claude Opus 4.8 and Kimi K2.7 through side-by-side creative coding tests (raycaster engines, neon city flight, racing, solar system, voxel runner, liquid-in-a-bowl interaction, and landing pages) and discusses benchmark results and practical tradeoffs. Opus 4.8 generally produces smoother, more playable outputs and leads several tests, while GLM 5.2 wins some rounds (notably a labeled, interactive solar system, voxel runner, and the liquid demo) and scores #1 on Design Arena. The script emphasizes GLM 5.2 being MIT-licensed open source on Hugging Face and available via Ollama, cheaper on a coding plan, and easier to plug into agents via OAuth, while Claude is described as stronger overall but less flexible without paid API access. It also promotes an “agent operating system” and the AI Profit Boardroom community for setup files, tutorials, and coaching.00:00 GLM 5.2 vs Claude00:43 Open Source Advantages02:12 Raycaster Showdown03:21 Upgraded Raycaster04:25 Neon City Flight05:13 Racing And Solar06:19 Voxel Runner Winner07:13 Liquid Bowl Test07:41 Benchmarks Breakdown09:44 Landing Page Faceoff10:15 Final Verdict10:46 Agent OS Integration11:17 Boardroom Pitch13:19 Wrap Up
