GLM 5.2 just took the #1 spot among open-weight AI models with a working 1-million-token context window — so I put it to a real test: building a complete horror game from scratch, since game logic and state-machine handling are exactly what Z.ai claims this model is built for.
In this video, I explain GLM 5.2 in simple terms, including free vs paid usage, real API costs, best use cases, coding performance, AI agent use, long-context features, and whether it is worth using compared to other top AI models like Claude Fable 5, Claude Opus 4.8, ChatGPT 5.5, and other coding models.
What GLM 5.2 is and what's genuinely new compared to GLM 5.1
- The full horror game build — what GLM 5.2 got right, where it broke, and -how it handled level logic, scoring, and game state
- How to use GLM 5.2 for free (self-hosting the open MIT-licensed weights, trial credits, and free-tier limits)
- The real GLM Coding Plan pricing — Lite, Pro, and Max — and whether paying is actually worth it
- The best real-world use cases for GLM 5.2 right now, from long-context coding agents to full repo-scale projects
GLM 5.2 launched on June 13, 2026 from Z.ai (Zhipu AI), built specifically for long-horizon coding and agentic tasks. It ships with a genuinely usable 1M-token context window, two thinking-effort modes, and open weights — and Z.ai claims it beats GPT-5.5 on several long-horizon coding benchmarks at a fraction of the cost. I tested that claim myself, so you don't have to guess.
If you're trying to decide whether GLM 5.2 is worth your time, or your money, this is the one video that covers the model, the test, and the real costs in one place.
