“World-class reasoning and programming — all in a single chat model.”The Essentials: GLM-4.5 is the latest member of the GLM family, designed to deliver smarter, clearer, and more powerful conversations. It’s optimized to combine strong reasoning, advanced programming, and multilingual fluency into one reliable model. Why It Stands Out:
- Strong performance across reasoning, math, science, and programming benchmarks.
- Handles long contexts up to 128k tokens, making it ideal for lengthy documents and conversations.
Where It Shines:
- Customer support & global work → fluent in English, Spanish, Chinese, and more.
- Programming → builds full applications, debugs large repositories, and understands both code and design logic.
- Research & analysis → provides clear, well-grounded answers with explanations that are easy to follow.
- Complex conversations → keeps track of long threads, maintains coherence, and adapts to different communication styles.
Numbers That Matter:
- Consistently ranks in the top 3 across 12 benchmarks (reasoning, programming, and multilingual tasks).
- BrowseComp (web understanding) → 26.4% accuracy, beating Claude-4-Opus (18.8%) and close to o4-mini-high.
- Programming → 64.2% on SWE-bench Verified, outperforming GPT-4.1 (48.6%).
- Math & Science → 90%+ on AIME24 and Math500, rivaling top research-level models.
Why It Matters:
GLM-4.5 is built to be practical and cost-efficient without sacrificing depth or clarity. Whether for multilingual support, programming, research, or long conversations, it delivers enterprise-grade performance in a reliable chat model.
