Free AI Video Generation

Generate AI videos for free — batch, concurrent, and stable, even during peak time.

What this tool does

This is a free AI video generation tool that solves three common pain points:

• Batch: submit many video tasks at once instead of one by one;
• Concurrent: control how many videos generate at the same time for faster output;
• Queue & tracking: tasks queue up and retry automatically during peak time, with clear progress.

Videos are generated by your own API keys connecting directly to the official service. This tool only schedules tasks — it does not resell or add fees.

How to start (free)

1. Visit agnes-ai.cn, register and log in;
2. Apply a free API key from your console;
3. Paste the key into the "API Keys" section of this tool and start generating.

Boost success rate with multiple API keys

Adding more than one API key is the easiest way to improve generation success. Here's why and how:

• Why: a single key can be rate-limited (429) or temporarily blocked during peak time. With multiple keys, the tool rotates between them automatically, so one limited key won't stall your whole queue.
• How: add 2–5 keys in the "API Keys" area. The tool picks keys intelligently and retries failed submissions with another key.
• Note: once a task is created, it polls progress with the same key that created it (the key is bound to the video ID). So adding more keys mainly helps at the submission stage.
• Tip: keep your keys valid and with sufficient balance; a failed or expired key is a common cause of generation failure.

Submit your first video task

1. Type your video prompt in the prompt box;
2. Choose model, aspect ratio, and duration (12s by default);
3. Optional: upload reference images (up to 5) or reference audio (up to 3), or set first/last frames;
4. Click "Submit" — the task enters the queue, auto-submits, and shows progress.

Generating during peak time

Official services often return 429 (rate limit) or 503 (queue full) during busy hours. The tool handles this by auto-retry, queueing, and concurrency control. Submit everything into the queue once, and it will keep submitting in the background — no need to click repeatedly. See the peak-time guide for details.

Video keeps failing?

Common causes: rate limit (429), queue full (503), an expired or invalid API key, or timeout. Check the error message on the failed task, then see the troubleshooting guide.

FAQ

Is AI video generation free?

Yes. No sign-up or login is required on this tool. You only need a free API key from agnes-ai.cn.

How do I make generation more reliable?

Add multiple API keys so the tool can rotate and retry, and raise the retry count. During peak time, rely on the queue instead of submitting repeatedly.

Will my running tasks be lost if I refresh the page?

No. In-progress tasks keep their server slot and resume polling after refresh. Queued tasks' materials are also saved temporarily.

Can I generate multiple videos at once?

Yes. Submit several tasks and adjust the "max concurrent tasks" setting to control how many run at once.
