Streaming

Stream responses token by token for a faster, real-time feel.

Enable streaming

Set "stream": true in your request. The API responds with server-sent events (SSE), each carrying a partial chunk.

bash

curl https://api.literouter.com/v1/chat/completions \
  -H "Authorization: Bearer $LITEROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "glm-5.2",
    "messages": [{ "role": "user", "content": "Write a haiku about the sea." }],
    "stream": true
  }'

python

stream = client.chat.completions.create(
    model="glm-5.2",
    messages=[{"role": "user", "content": "Write a haiku about the sea."}],
    stream=True,
)

for chunk in stream:
    delta = chunk.choices[0].delta.content
    if delta:
        print(delta, end="", flush=True)

javascript

const stream = await client.chat.completions.create({
  model: "glm-5.2",
  messages: [{ role: "user", content: "Write a haiku about the sea." }],
  stream: true,
});

for await (const chunk of stream) {
  const delta = chunk.choices[0]?.delta?.content || "";
  if (delta) process.stdout.write(delta);
}
