call it

model=

deepinfra/zai-org/GLM-4.5

this model has no managed policy yet, so call the provider endpoint directly. every id in the endpoints table works the same way

Base url is https://router.requesty.ai/v1 for every id here. One key reaches the whole catalog.

Change the base url, use your Requesty key, set the model to any id in the call pane. Existing OpenAI SDK code needs no other edit, and the same key reaches every other model in the catalog, so switching later is a one-parameter change. Browse all models

notes

reference

The GLM-4.5 series models are foundation models designed for intelligent agents. GLM-4.5 has 355 billion total parameters with 32 billion active parameters, while GLM-4.5-Air adopts a more compact design with 106 billion total parameters and 12 billion active parameters. GLM-4.5 models unify reasoning, coding, and intelligent agent capabilities to meet the complex demands of intelligent agent applications.

questions 5

Which providers serve glm-4.5?

glm-4.5 is available from 2 providers through Requesty: DeepInfra Inc., Z.ai. All endpoints share one OpenAI-compatible API and one key, and Requesty fails over between them automatically.

How much does glm-4.5 cost?

Pricing starts at $0.60 per million input tokens and $2.20 per million output tokens on the cheapest provider. Prices vary by provider and region; the table above shows every endpoint. Requesty charges exactly what the upstream provider charges, with no markup.

Is glm-4.5 open weights?

Yes. glm-4.5 is an open-weights model from Z.AI, which is why multiple inference providers can host it. Provider choice affects price, latency, and data-privacy terms, all compared above.

What is the context window of glm-4.5?

glm-4.5 supports up to 131K tokens of context, with up to 98K output tokens per response. Some providers expose a smaller window; check the per-endpoint context column above.

How do I use glm-4.5 with the OpenAI SDK?

Install the OpenAI SDK, set base_url to "https://router.requesty.ai/v1", set your API key to your Requesty key, and set the model to "deepinfra/zai-org/GLM-4.5" or any endpoint id from the table above. The quickstart section shows Python, JavaScript and cURL snippets.

route glm-4.5 through one endpoint

One key for 2 providers on this model and 600+ others. No markup on provider prices, automatic failover, caching built in. Weekly aggregates in the measured pane come from production traffic routed through Requesty, one line per provider on a shared axis. Methodology
