Hybrid-reasoning GLM release that made the 4.5 line broadly useful
GLM-4.5 by zhipuai is offered by 20 providers on this page. Public prices are shown for 18 of them. Its official list price is $0.60 per 1M input tokens and $2.20 per 1M output tokens. The lowest paid channel is 302.AI at $0.286 / $1.14 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. It also has 1 free ($0) channel; free tiers usually carry rate limits, and subscription-covered access bills $0 per token only after the subscription fee.
Artificial Analysis rates it 19.7 on the Intelligence Index. Against its lowest blended price of $0.50 per 1M, that is roughly 39 index points per dollar, which is the value ratio the leaderboards rank on.
The context window is 131,072 tokens at the reference host, but hosts report different limits, from 128,000 to 131,072, so the usable window depends on the provider you pick. It supports reasoning and tool use. 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.
