Why streaming?

Streaming lets your app display responses as they’re generated, instead of waiting for the full response. Essential for chatbots and interactive UIs.

​
Python

from openai import OpenAI

client = OpenAI(
    base_url="https://kymaapi.com/v1",
    api_key="ky-your-api-key"
)

stream = client.chat.completions.create(
    model="qwen-3.6-plus",
    messages=[{"role": "user", "content": "Write a poem about AI"}],
    stream=True
)

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

​
JavaScript

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://kymaapi.com/v1",
  apiKey: "ky-your-api-key",
});

const stream = await client.chat.completions.create({
  model: "qwen-3.6-plus",
  messages: [{ role: "user", content: "Write a poem about AI" }],
  stream: true,
});

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