Z.ai reports a major app-development jump for GLM-5.2

# GLM-5.2 ## Description: GLM-5.2 is the latest flagship large language model from Z.ai (zai-org), designed for long-horizon tasks with a solid 1M-token context window. It represents a substantial leap in extended-context capability over its predecessor GLM-5.1, featuring the IndexShare architecture that reuses the same indexer across every four sparse attention layers, reducing per-token FLOPs by 2.9x at 1M context length. GLM-5.2 delivers state-of-the-art performance across reasoning, coding, and agentic benchmarks, with multiple thinking effort levels to balance performance and latency. GLM-5.2 was developed by Z.ai (zai-org) as a part of the GLM model family. _This model is ready for commercial or non-commercial use._ ## Third-Party Community Consideration [...] ### Deployment Geography: Global ### Use Case: Developers and researchers can use GLM-5.2 for long-horizon reasoning tasks requiring extended context, complex software engineering and agentic workflows, mathematic

Results: - GLM-5.1: 21/70 - GLM-5.2: 48/70 - Claude Fable 5: 56/70 That's more than a twofold improvement from GLM-5.1 to GLM-5.2. These come from an internal benchmark of 35 challenging mobile development tasks, each run twice for a total of 70 trials. We measured task completion, defined as core features working without major issues. Jen W., graphic [...] Jen W., graphic Impressive jump, especially given how long-horizon app-development tasks are. I’ve been analyzing the anti-hack section of your blog post, and it seems like app-building and debugging may have different reward-hacking modes: app-building can hack by downloading/copying the target solution, while debugging can

GLM-5.2's new capabilities include: [...] GLM-5.2 also introduces effort level control, enabling users to explicitly balance model capability against task execution speed and computational cost. As shown in the figure, GLM-5.2 delivers substantially stronger agentic coding performance than GLM-5.1 at comparable token budgets, with its capability roughly positioned between Claude Opus 4.7 and Claude Opus 4.8 under similar token consumption. Moreover, the Max effort level allows users to allocate additional computation when higher performance is required in challenging task
