GLM on RouterHub

# GLM 5.3, Flash and Abliterated API pricing and setup
Build apps with GLM using the OpenAI-compatible Chat Completions API, one RouterHub API key, and prepaid credits. Compare published input, output, and cached input rates before choosing your model.

## GLM models and prices

- [GLM 5.3 Flash](https://routerhub.si/models/glm-5.3-flash) · `glm-5.3-flash`
- [GLM 5.3](https://routerhub.si/models/glm-5.3) · `glm-5.3`
- [GLM 5.3 Flash Abliterated](https://routerhub.si/models/glm-5.3-flash-abliterated) · `glm-5.3-flash-abliterated`
- [GLM 5.3 Abliterated](https://routerhub.si/models/glm-5.3-abliterated) · `glm-5.3-abliterated`
See [Models & pricing](https://routerhub.si/models) for current model IDs, rates, availability, and limits. These details can change; use that page before sending a request.
Input is the prompt you send; output is the response you receive. Cached input rates apply when the provider reports a cache hit. Prices come from RouterHub's current public catalogue; these are RouterHub rates. No separate subscription is required.
Compare GLM 5.3 with GLM 5.3 Flash by input and output price. Change the example model ID to select either published GLM model.

## Get an API key

- [Create a RouterHub account](https://routerhub.si/register?model=glm-5.3-flash).
- [Add prepaid credits](https://routerhub.si/dashboard/billing).
- [Create an API key](https://routerhub.si/dashboard/keys) and keep it in your local environment.
- Send a short Chat Completions request, then check [Usage](https://routerhub.si/dashboard/usage) for its cost.

## Send your first GLM API request
Use the exact model ID `glm-5.3-flash` with `https://routerhub.si/v1/chat/completions`. Set `ROUTERHUB_API_KEY` in your local environment. This request uses prepaid credits.

### cURL

```
curl --connect-timeout 30 --max-time 600 https://routerhub.si/v1/chat/completions \
  -H "Authorization: Bearer $ROUTERHUB_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"glm-5.3-flash","messages":[{"role":"user","content":"Reply with OK."}]}'
```

### Python
Install the OpenAI Python SDK with `pip install openai`.

```
import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["ROUTERHUB_API_KEY"],
    base_url="https://routerhub.si/v1",
    timeout=600.0,
)
response = client.chat.completions.create(
    model="glm-5.3-flash",
    messages=[{"role": "user", "content": "Reply with OK."}],
)
print(response.choices[0].message.content)
```

### Node.js
Install the OpenAI JavaScript SDK with `npm install openai`.

```
import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.ROUTERHUB_API_KEY,
  baseURL: "https://routerhub.si/v1",
  timeout: 600000,
});
const response = await client.chat.completions.create({
  model: "glm-5.3-flash",
  messages: [{ role: "user", content: "Reply with OK." }],
});
console.log(response.choices[0].message.content);
```
Python SDK timeouts use seconds; JavaScript SDK timeouts use milliseconds. Both examples allow ten minutes per attempt. SDKs may retry automatically; check Usage and the request ID before manually rerunning a timeout.
