GLM 5.2 in 9 Minutes: The Open-Weight Rival to GPT-5.5

Official Sources

What This Video Covers

GLM 5.2 in 9 Minutes explains GLM 5.2 as an open-weight rival to GPT-5.5. The video reviews the model, works through benchmarks and pricing, and finishes with a live demo running GLM 5.2 inside OpenCode.

This post is a companion to the video above. Watch the nine-minute walkthrough for the benchmarks and the live demo, then use the links here to place GLM 5.2 in context.

The Idea in One Line

An open-weight model aimed squarely at a frontier closed model. GLM 5.2 is framed as a direct rival to GPT-5.5, which is the interesting part: the comparison is not open versus closed in the abstract, it is one specific open-weight release measured against a specific proprietary one.

Why It Matters

Three angles make this worth a look:

• Open weights change the math. When a model ships its weights, pricing and deployment options open up in ways a hosted-only model cannot match. The video spends time on pricing for exactly this reason, and the GLM 5.2 cost math for open-weight coding models post goes deeper on the numbers.
• Benchmarks set expectations. Positioning a model against GPT-5.5 is a claim you can test. The GLM 5.2 developer guide and the open-weights coding showdown put those numbers next to the alternatives.
• A live demo beats a spec sheet. Running the model in OpenCode shows how it behaves on real coding work, not just how it scores.

Where It Fits

GLM 5.2 sits in a crowded field of open-weight coding models. If you are weighing access and cost, GLM 5.2 free and cheap access covers how to try it without a big commitment. For the closed-model side of the comparison, the GPT-5.5 hallucination benchmark against GLM 5.2 looks at where each model lands.

Getting Started

The path the video demonstrates is simple: try GLM 5.2 inside a coding environment like OpenCode and judge it on your own tasks. Start with a small, well-scoped job so you can compare its output against a model you already trust before leaning on it for anything larger.

Watch the full GLM 5.2 in 9 Minutes walkthrough above, then run the model against a task of your own and see how the open-weight option holds up.
