GLM vision model for visual reasoning, documents, and multimodal agents
GLM-4.6V by zhipuai is offered by 14 providers on this page. Public prices are shown for 13 of them. Its official list price is $0.30 per 1M input tokens and $0.90 per 1M output tokens. The lowest paid channel is ZenMux at $0.14 / $0.42 per 1M, about 2.1× below the list price. That channel is a third-party gateway, so confirm its availability and rate limits before depending on it.
Artificial Analysis rates it 16.9 on the Intelligence Index. Against its lowest blended price of $0.21 per 1M, that is roughly 80 index points per dollar, which is the value ratio the leaderboards rank on. Median output speed is 66 tokens per second, with 3.69s to the first token.
The context window is 128,000 tokens at the reference host, but hosts report different limits, from 128,000 to 200,000, so the usable window depends on the provider you pick. It supports reasoning and tool use. Accepted input modalities are Text, Image, and Video. The weights are open, so it can also be self-hosted or served through a gateway of your choice. Providers report the capability flags inconsistently, so verify a specific feature against the host you plan to use. Its training knowledge cuts off at 2025-04.
Quality is independently evaluated by Artificial Analysis. Speed/latency are model-level medians.
