When it comes to LLMs, we are getting smarter ones all the time. GLM-4.6 from Z.ai is a new version with advanced agentic, reasoning and coding capabilities. It has a long-context processing of up to 200k tokens. It can hold its own against Claude 4 and DeepSeek V3.2 EXP across a bunch of benchmarks. In real-world development tasks, GLT-4.6 can perform almost on par with Claude Sonnet 4.

As Z.ai explains, GLM-4.6 completes tasks with about 15% fewer tokens than GLM-4.5. This model is also better at tool using search-based agents. You can use it with Claude Code, Kilo Code, Roo Code, and Cline.
