Everything on Z.ai's open-weights GLM-5.2 coding model: how to access it free and cheap, what it costs to run, how it stacks up against DeepSeek, Qwen, and the frontier labs, and why an MIT-licensed model is beating closed ones on real benchmarks.

GLM-5.2 is an MIT-licensed open-weights coding model. Cheapest routes: OpenRouter hosts from about $0.36 per million input tokens, Z.ai's API, or self-host.

GLM-5.2 cost math: when Z.ai's open-weights coding model actually saves money, with per-token pricing, a worked cost-per-task example and a decision guide.

GLM-5.2 vs DeepSeek V4 vs Qwen3 vs Kimi K3: open-weights coding models compared on benchmarks, pricing, context windows, self-host footprint and best picks.

GPT-5.5 hallucinates 86% of the time on AA-Omniscience when it does not know, versus 28% for MIT-licensed GLM-5.2. What the metric measures and why it matters.

Run GLM-5.2 locally with Unsloth dynamic quantization: hardware math for a 256GB Mac or 24GB GPU, quantization tradeoffs and lessons from the HN thread.

GLM 5.2 and the AI margin collapse thesis: why open-weights models could squeeze frontier lab margins, where HN pushes back, and what it means for model choice.
