GLM-4.6
Overview
GLM-4.6 is a open reasoning + coding model from Z.ai (Zhipu), released in 2025. It accepts text as input and produces text. With a context window of 200K tokens, it is well suited to agentic coding with claude code/cline and long-context reasoning.
Capabilities
On reasoning, GLM-4.6 is rated excellent, while its coding ability is excellent. Multimodal support: No. These characteristics make it a strong fit for agentic coding with claude code/cline and long-context reasoning. As with any frontier system, real-world performance depends heavily on how you prompt and integrate it.
Availability & Pricing
GLM-4.6 is accessible via an API. Pricing model: Open weights (MIT) / API. Availability and pricing for AI models change frequently; confirm the latest details from Z.ai (Zhipu) before building on it.
Best Use Cases
The sweet spot for GLM-4.6 is agentic coding with claude code/cline and long-context reasoning. Teams choosing a model should weigh context length, cost, latency and modality against their workload — GLM-4.6 is a particularly good match when those priorities align with its strengths.
