GLM-4.6 is an established model in Zhipu’s GLM-4 line, built around a large context window and a focus on coding and agentic tool use. It offers most of GLM-4.7’s practical value and is one of the more mature GLM chat models.
z.ai publishes GLM-4.6 at $0.60 per 1M input tokens and $2.20 per 1M output tokens, the same value tier as GLM-4.7.
It advertises a large ~200K-token context window — a defining feature of GLM-4.6 for long-file and repository-scale work.
Architecture & training signals
GLM-4.6 is part of the GLM-4 line from Zhipu AI, which earned attention for capable open-weight models tuned for coding and agentic tasks and for long context. It is a reasoning-capable chat model with tool-calling and JSON over an OpenAI-compatible endpoint. Like the rest of the GLM line, it returns a non-standard reasoning_content field alongside content in its OpenAI-compatible responses; integrations should read content for the final answer and treat reasoning_content as an optional trace.
Where it shines
- Long-context work — its large window is the headline feature.
- Coding and agentic tool use.
- A cost-effective, mature GLM option.
Where it falls short
- GLM-4.7 and the GLM-5 generation may edge it on newer capabilities.
- No Tokonomix benchmark scores yet; validate on your workload.
- Non-EU hosting.
Real-world use cases
- Repository-scale code understanding and generation.
- Long-document analysis where the full text must fit in one call.
- Agentic pipelines needing reliable tool-calls.
Tokonomix benchmark snapshot
GLM-4.6 is newly registered on Tokonomix and not yet activated, so we have not run it through our weekly intelligence test or speed benchmark. There are no Tokonomix scores to report yet — and we will not invent any.
When it goes live, it enters the same weekly harness as every other model: identical prompts, an independent cross-family judge, and reproducible latency and cost measurements. Until then, treat the pricing and capability notes on this page as the vendor-published starting point, not as measured Tokonomix results.
EU privacy & data residency
GLM-4.6 is built by Zhipu AI (z.ai), a China-headquartered lab, and is served from non-EU infrastructure. This is important to state plainly: routing a prompt to this model is not an EU-data-residency or GDPR-sovereign choice, and Tokonomix will never tag it as one.
If your use case requires data to stay within the EU, pick a model whose provider is EU-hosted (for example our OVH or Azure-EU routes) rather than a GLM model. Tokonomix keeps z.ai out of every EU-only / sovereign routing set by design. Use GLM where its capability or price is the priority and cross-border processing is acceptable for that workload.
Verdict & alternatives
GLM-4.6 is a dependable, long-context, coding-focused GLM at a value price. If you want the newest iteration, GLM-4.7; if you want the newest generation entirely, GLM-5.x. For free experimentation, pair it with the GLM Flash tiers.
