# Genesis

Genesis is one of the three MatrixOne Intelligence platforms, alongside AI Studio and MatrixOne. It serves as the **model gateway**, providing a model marketplace, online debugging, API keys, usage, and call observability. After obtaining a Genesis API Key, you can call models from any application through an OpenAI-compatible protocol. Usage is charged to a **separate Genesis Credit ledger**.

AI Studio features such as agent conversations, workflows, and knowledge-base Q&A also call models internally, but use the **AI services** ledger and **do not count toward** Genesis user-side usage. To determine which ledger a call belongs to, look only at its entry point: intelligence used through the UI → AI services; models called with your own API Key → Genesis. See [Credit and billable items](../billing/credit-and-pricing.md).

## Console entries

Genesis has a separate sign-in entry and console from AI Studio. Its sidebar maps to these guides:

| Page | Purpose | Guide |
| --- | --- | --- |
| Models | Marketplace: filter models, view capabilities and pricing, copy model IDs | [Model marketplace](models.md) |
| Debug | Online playground for chat, embeddings, rerank, and other endpoints | [Debug models](debug.md) |
| Keys | Create and manage API Keys, model scope, quotas, and rate limits | [Manage API Keys](api-keys.md) |
| Usage Guide | Base URL, authentication, and multi-language code samples | [Integrate with apps](integrate.md) |
| Dashboard / Usage / Logs / Notifications | Runtime overview, statistics, request details, and alert channels | [Monitor runtime](observe.md) |

## Find by task

| Task | Guide |
