Using GLM 4.5 Air with Jev

Jev is TypeSafe AI's System One model. It reads each request first and decides which model in your pool answers, with a calibrated confidence on that call. GLM 4.5 Air does the answering when Jev sends it work, or when you name it yourself. At list price GLM 4.5 Air falls in the llm11-fast band, but no pack routes to it because it does not advertise structured output, which the verification checks rely on. You can still pin it: pass z-ai/glm-4.5-air as model and routing steps aside while verification still runs.

Jev is new, so we have not published results for GLM 4.5 Air with and without it, and this page does not invent any. Every response comes with a receipt that names the model that answered and what it cost against your most expensive model, so you can measure the pairing on your own traffic.

What a request costs

List price arithmetic, the same sum a receipt does. llm11 adds nothing per request; the only fee is on buying credits.

Call it

Same OpenAI request shape. Naming the model pins it, so nothing is routed, and the answer is still checked.

python

from openai import OpenAI

client = OpenAI(base_url="https://www.llm11.com/v1", api_key="llm11_live_...")

res = client.chat.completions.create(
    model="z-ai/glm-4.5-air",

GLM 4.5 Air does the answering when Jev sends it work, or when you name it yourself. At list price GLM 4.5 Air falls in the llm11-fast band, but no pack routes to it because it does not advertise structured output, which the verification checks rely on.

Is GLM 4.5 Air a System One model?
No. GLM 4.5 Air answers requests. The System One model is Jev, which decides which model answers each one, so the two do different jobs and llm11 uses both.
How much does GLM 4.5 Air cost?
$0.130 per million input tokens and $0.850 per million output tokens. A 4,000 token prompt with a 500 token answer costs about $0.00095, so a thousand of them is about $0.945. llm11 passes provider list price through and charges 5% when you buy credits.
What is the GLM 4.5 Air context window?
131,072 tokens, with up to 98,304 tokens in a single reply.
Does GLM 4.5 Air support tool calling and structured output?
The catalogue lists tool calling and reasoning controls, but it does not list structured output.
Can I use GLM 4.5 Air through llm11?
Yes. Set model to z-ai/glm-4.5-air on the OpenAI-compatible endpoint and the request goes to it directly, with verification still running.
Does Jev route to GLM 4.5 Air?
Routing decisions are made by Jev, TypeSafe AI's System One model. At list price GLM 4.5 Air falls in the llm11-fast band, but no pack routes to it because it does not advertise structured output, which the verification checks rely on.
