How to choose a GLM 4.5 inference provider
GLM 4.5 is indexed here as a text model by Z.ai, with 1 provider endpoint from Z.ai. The comparison preserves each exact OpenRouter routing tag so pricing and performance observations can be connected to the route an application would actually request.
Match the endpoint to the workload
The model publishes a 131.1K-token context window. It accepts text input and returns text output. 9 distinct supported parameters appear across the listed routes. Confirm limits on the specific endpoint rather than assuming every host exposes the same configuration.
Compare the real request economics
Z.ai currently has the lowest estimated cost for the standard 1,000-input/500-output-token sample at $0.0017. Input-heavy and output-heavy applications can produce a different result, so review both per-million-token prices in the endpoint table.
Balance response start and generation speed
Z.ai currently has the shortest estimated 500-token response at 21.74 seconds. Z.ai is the single endpoint closest to the current ideal cost/speed combination. Recent observations can change, so validate finalists with your own prompts.
