Grok Models
POST /v1/chat/completions
base_url to Crazyrouter and pass the Grok model ID in model.
Model availability depends on channel status, token permissions, and the live pricing configuration. Before production use, call GET /v1/models with the same API key and confirm that the target model is visible.
Common Models
| Model | Description |
|---|
grok-4 | Main Grok 4 model |
grok-4-fast | Grok 4 fast variant |
grok-4-fast-non-reasoning | Grok 4 fast non-reasoning variant |
grok-4-fast-reasoning | Grok 4 fast reasoning variant |
grok-4.1 | Grok 4.1 |
grok-4.1-fast | Grok 4.1 fast |
grok-4.1-thinking | Grok 4.1 thinking |
grok-4.2 | Grok 4.2 |
grok-4-0709 | Dated Grok 4 model |
Older grok-4 / grok-4.1 names may still appear in historical calls or compatibility setups, but the public pricing surface primarily keeps the grok-4* family. New integrations should start with grok-4, grok-4.1, grok-4.2, or the fast/reasoning variants.
Minimal Request
curl https://api.crazyrouter.com/v1/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d '{
"model": "grok-4",
"messages": [
{
"role": "user",
"content": "Reply with one short sentence: what is Grok?"
}
],
"temperature": 0.7,
"max_tokens": 120
}'
from openai import OpenAI
client = OpenAI(
api_key="YOUR_API_KEY",
base_url="https://api.crazyrouter.com/v1",
)
response = client.chat.completions.create(
model="grok-4",
messages=[
{"role": "user", "content": "Reply with one short sentence: what is Grok?"}
],
temperature=0.7,
max_tokens=120,
)
print(response.choices[0].message.content)
import OpenAI from "openai";
const client = new OpenAI({
apiKey: "YOUR_API_KEY",
baseURL: "https://api.crazyrouter.com/v1",
});
const response = await client.chat.completions.create({
model: "grok-4",
messages: [
{ role: "user", content: "Reply with one short sentence: what is Grok?" },
],
temperature: 0.7,
max_tokens: 120,
});
console.log(response.choices[0].message.content);
Streaming
Set stream: true to use SSE streaming.
curl https://api.crazyrouter.com/v1/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d '{
"model": "grok-4-fast",
"stream": true,
"messages": [
{
"role": "user",
"content": "Write a concise API migration checklist."
}
]
}'
Reasoning Variants
For Grok models containing reasoning or thinking in the name, keep the request shape simple:
{
"model": "grok-4-fast-reasoning",
"messages": [
{
"role": "user",
"content": "Compare two implementation options and explain the tradeoffs."
}
],
"max_tokens": 800
}
Reasoning fields, search fields, and experimental parameters can differ by upstream channel. For cross-channel stability, prefer standard OpenAI Chat fields: model, messages, temperature, top_p, max_tokens, and stream.
