GLM-5.2 — The Open Weights Coding Powerhouse

Released June 2026 by Z.AI, GLM-5.2 is the #1 ranked open-weights model on the Artificial Analysis Intelligence Index (score: 51). It’s a 753B parameter Mixture-of-Experts model with 40B active parameters per token, offering frontier performance under an MIT license.

Why GLM-5.2 Matters

Feature	GLM-5.2	GPT-5.5	Advantage
Coding Benchmarks	#1	#2-3	🏆 GLM-5.2
Price (per 1M tokens)	$1.40 / $4.40	$15 / $60	💰 4-10x cheaper
Speed (tok/s)	105	~80	⚡ 30% faster
Context Window	1M	128K	📚 8x larger
License	MIT	Proprietary	🔓 Total freedom
Self-Hosting	✅ Yes	❌ No	🏠 Private deployment

Prompting Strategy

Coding first. GLM-5.2’s strongest domain is programming. Structure coding prompts like competitive programming problems — clear spec, constraints, expected output format.
1M context is real. Upload entire codebases, book-length documents, or full log files for holistic analysis.
Structured output shines. GLM-5.2 produces excellent JSON when you define the schema upfront.
Chinese and English. Native bilingual support — no translation overhead for mixed-language tasks.
