What you need to know about GLM 4.5V
Z.ai (Zhipu), based in China, put GLM 4.5V online on August 11, 2025. It accepts text and images as input and produces text. Its context window reaches 65,536 tokens, larger than 12 % of the models in the registry, and it can write up to 16,384 tokens in one go.
It has been available for about 14 months, long enough for its prices and scores to have settled.
GLM 4.5V pricing
On OpenRouter, GLM 4.5V costs $0.6 per million input tokens and $1.8 per million output tokens. Counting three tokens read for every token written, its average price is $0.9 per million, more expensive than 55 % of paid models (1.2 times the median of $0.76).
A concrete example: a task that sends 2,000 tokens (about 1,500 words) and receives a 500-token answer costs $0.0021. At 1,000 tasks a day, budget $63 a month. The price calculator redoes this with your own volumes.
Tokens already sent and cached are billed at $0.11 per million.
Performance and benchmarks
Epoch AI does not yet publish a capabilities index for GLM 4.5V. We therefore show no made-up performance rating: only price, context and features count towards its score.
Features, privacy and local use
- It supports tool calling, so it can drive an AI agent, call APIs or MCP servers.
- It can answer in an enforced JSON format (structured outputs).
- It is a reasoning model: it "thinks" before answering, which helps on hard tasks but uses more output tokens.
- Its knowledge stops at December 2024.
Its weights are open and downloadable from Hugging Face: you can run it on your own machines without sending your data to a third party.
