What you need to know about GLM 5 Turbo
Z.ai (Zhipu), based in China, put GLM 5 Turbo online on March 15, 2026. It accepts text as input and produces text. Its context window reaches 202,752 tokens, larger than 37 % of the models in the registry, and it can write up to 131,072 tokens in one go.
It has been available for about 7 months, long enough for its prices and scores to have settled.
GLM 5 Turbo pricing
On OpenRouter, GLM 5 Turbo costs $1.2 per million input tokens and $4 per million output tokens. Counting three tokens read for every token written, its average price is $1.9 per million, more expensive than 70 % of paid models (2.5 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 $0.0044. At 1,000 tasks a day, budget $132 a month. The price calculator redoes this with your own volumes.
Tokens already sent and cached are billed at $0.24 per million.
Performance and benchmarks
Epoch AI does not yet publish a capabilities index for GLM 5 Turbo. 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 weights are not published: it can only be used through the Z.ai (Zhipu) API or a broker such as OpenRouter, which means sending your data off your machines.
