Alibaba's alibaba/happyhouse-1.1 is a high-fidelity video generation model. It supports text-to-video and image-to-video workflows with configurable duration, aspect ratio, and resolution, plus first-frame and last-frame control for guided scene composition.

Generates cinematic clips with consistent motion, camera control, and optional native audio. Billed per second of generated content.

alibaba/happyhouse-1.1 is fully OpenAI-compatible — drop in your existing OpenAI Python or Node SDK and switch `baseURL` to `https://api.tokenlx.ai`. TokenLX transparently routes your requests to the optimal provider endpoint while preserving streaming, function-calling, and structured-output semantics.

Sample code & API

TokenLX normalizes requests and responses across providers. Use any OpenAI SDK or our native SDK.

import requests, time

headers = {"Authorization": "Bearer sk-tokenlx-...", "Content-Type": "application/json"}

resp = requests.post(
    "https://api.tokenlx.ai/v1/aigc/video/tasks",
    headers=headers,
    json={
        "model": "happyhouse-1.1",
        "prompt": "新年烟花在城市夜空中绽放",
        "duration": 8,
        "resolution": "720P",
        "aspectRatio": "16:9",
    },
)
task = resp.json()
task_id = task.get("taskId") or task.get("task_id") or task.get("id")

# 轮询结果
while True:
    result = requests.get(
        f"https://api.tokenlx.ai/v1/aigc/video/tasks/{'{'}task_id{'}'}?model=happyhouse-1.1",
        headers=headers,
    ).json()
    print("status:", result.get("status"))
    if result.get("status") in ("completed", "succeeded", "done"):
        print(result)
        break
    time.sleep(10)
