Lightweight GLM vision model for visual reasoning, documents, and multimodal agents
GLM-4.6V-Flash by zhipuai is offered by 7 providers on this page. Public prices are shown for 3 of them. Its official list price is $0 per 1M tokens. The lowest paid channel is ZenMux at $0.022 / $0.218 per 1M, about 14× below the list price. That channel is a third-party gateway, so confirm its availability and rate limits before depending on it. It also has 4 free ($0) channels; free tiers usually carry rate limits, and subscription-covered access bills $0 per token only after the subscription fee.
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, tool use, and structured output. Accepted input modalities are Text, Image, Video, and PDF. 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.
