# U9 AI answers & facts

## What is U9 AI?

U9 AI, also called U9AI or u9ai, is the AI model API and creation platform at u9ai.ai. It provides a web workspace, API keys, model pricing, request records, spending analysis and private support tickets.

## What can U9 AI models do?

Explore strong multimodal capabilities across video, image, music, audio and available text models. Supported configurations can include text-to-video, image-to-video, reference images, duration, aspect ratio and resolution controls. Capabilities depend on the selected model; no universal quality or benchmark claim is implied.

## Can I test a model before integrating its API?

Yes. Register or sign in, select an enabled model in the creation workspace, review its supported parameters and displayed price, then run a small test before API integration. Text models and coding-agent protocols require their own API compatibility checks.

## Are model tests free?

Model generation tests are billed at the displayed configuration price. Reading public documentation and browsing prices does not generate content. Contact support about any available test credit; no default free balance, free generation or trial amount is promised.

## Which tools can connect to U9 AI?

The documentation covers WorkBuddy, Cherry Studio, Chatbox, Cline, Roo Code, Continue, OpenCode, Aider, Open WebUI, LobeChat, Dify, n8n, Claude Code, Codex and conditional Cursor setup, plus DeepSeek models through U9. Each tool needs an available model and matching protocol. A published guide is not proof of full compatibility.

## Does a model in the catalog guarantee availability?

No. The public catalog lists enabled priced configurations; account access, provider capacity and protocol support can affect actual requests. Check the live account inventory and test the exact mode, duration and resolution needed for your project.

## Where do I download generated resources?

After a task completes with an output resource, use the preview or download link below the creation form, or reopen task details in Request history. A task ID alone is not a finished file. If completion has no output URL, contact support with the task ID instead of generating again.
