# Build with Novita AI

> Access AI models, run code in agent sandboxes, or deploy on GPUs. Choose a task below and get to a working result quickly.

> **[Call a model API](#choose-api-path)**
>
> Add hosted AI models to your application with an OpenAI-compatible API.

> **[Run code in a Sandbox](/guides/sandbox-your-first-agent-sandbox?utm_source=docs\&utm_medium=introduction\&utm_campaign=introduction_update\&utm_content=sandbox)**
>
> Give your agent an isolated environment to create a sandbox and run code.

## Choose how you want to call a model

> **[Send your first request](/guides/quickstart?utm_source=docs\&utm_medium=introduction\&utm_campaign=introduction_update\&utm_content=llm-manual#manual-api-request)**
>
> Create an API key, send a small LLM request, and verify the response yourself.

> **[Use your agent](/guides/quickstart?utm_source=docs\&utm_medium=introduction\&utm_campaign=introduction_update\&utm_content=llm-agent#use-your-agent)**
>
> Ask an agent to help connect to Novita AI, then verify the real API response.

## Before you run

* Sign in or [create a Novita account](https://novita.ai/user/register).
* Create or manage an [API key](https://novita.ai/settings/key-management).
* Confirm that your account has enough [credit](https://novita.ai/billing) for the product you want to use.

> **Use Novita AI with your agent**
>
> **No install — paste this into your agent chat:**
>
> ```text theme={"system"}
> Read https://raw.githubusercontent.com/novitalabs/novita-skills/main/skills/novita-ai/SKILL.md and use Novita AI for this task.
> ```
>
> **Optional — install once if your agent supports skills:**
>
> ```bash theme={"system"}
> npx skills add novitalabs/novita-skills --skill novita-ai
> ```
>
> The `novita-ai` skill covers model APIs, GPUs, Agent Sandbox, integrations, and troubleshooting. Your agent still needs a valid API key and available credit when it makes a request.
>
> [View the skill on GitHub →](https://github.com/novitalabs/novita-skills)
