# NoteGen
> Configure models in NoteGen through its built-in AIHubMix model platform for AI chat, note organization, writing assistance, and knowledge base retrieval.
NoteGen is a local-first, cross-platform Markdown app that helps you collect scattered information and organize it into clear notes with AI. AIHubMix is built into NoteGen as a model platform. After you enter your API Key and add a model, you can use models supported by AIHubMix.

Prerequisites
* Install and open NoteGen. This guide uses the NoteGen `0.38.2` desktop app.
* Create an API Key in the [AIHubMix Console](https://aihubmix.com/token).
* Prepare the ID of the model you want to use, for example `gpt-5.6-terra`. Copy model IDs from the [model list](https://aihubmix.com/models) to avoid typos.
1\. Open Model Services
Click the settings button in the top-right corner of the NoteGen window. In the settings sidebar, select **Model Services** under the **AI** group.
In the **Model platforms** list, click **AIHubMix**. This platform is built into NoteGen and shows a **Sponsor** badge next to its name.
3\. Enter the connection settings
On the **Connection** tab, enter the following:
* **API endpoint**: Preset to `https://aihubmix.com/v1`. Keep it unchanged. If the primary endpoint is temporarily unavailable, change it to the backup endpoint `https://api.inferera.com/v1`.
* **API Key**: Enter the API Key created in the AIHubMix Console.
* **Network Proxy**: Keep the default, **Inherit global proxy**.
Changes are saved automatically.
Enter the **API endpoint** up to `/v1`, for example `https://aihubmix.com/v1`. NoteGen adds API paths such as `/chat/completions` and `/embeddings` based on the model type.
4\. Add a chat model
Switch to the **Models** tab and click **Add Model**.
In the model card that expands automatically, enter the model details:
* **Model**: Click **Please select a model**, type the model ID in the search box, for example `gpt-5.6-terra`, and select it. If the model is not in the list, type the full model ID and click **Use "model ID"**. If a text box appears here instead, enter the model ID directly, or click the refresh button on the right side of the text box to fetch the model list again.
* **Model Type**: Select **Chat**. New models use **Chat** by default.
Leave the options under **Advanced Parameters**, such as Maximum Output Tokens, Context Window, and Temperature, at their default values unless you need custom settings. After you enter a model, the status next to the platform name changes from **Needs setup** to **Ready**.
5\. Test the connection
Click **Test Connection** in the upper-right corner of the model card. If **AI connection test passed** appears, the API Key, API endpoint, and model ID are working.
To add more models, repeat [step 4](#add-chat-model) and [step 5](#test-connection).
Use AIHubMix models
Select a model in AI chat
Click the close button in the top-right corner to return to the main window. In the status bar at the bottom of the window, click the current model name on the right, then select the model you added under the **AIHubMix** group.
Type a message in the chat panel on the right and send it. If you receive a normal reply, the configuration is complete. If the chat panel is not visible, click the **Show Right Sidebar** button in the top-right corner of the window.
Use AI in the editor
If no separate model is set for the editor, the editor's AI features use the chat model you selected. Select some text in a note, click the **AI** button in the floating toolbar, then choose **Polish**, **Concise**, **Expand**, or **Translate**. You can accept or discard the generated result.
To set a separate model for the editor, go to **Settings → Editor Settings** and choose one for **Editor model** in the **Default Models** section.
Configure knowledge base models (optional)
NoteGen's knowledge base uses an embedding model for semantic retrieval. A reranking model is optional and improves the order of retrieval results.
1. On the **Models** tab of the AIHubMix platform, click **Add Model**. Enter an embedding model ID, for example `text-embedding-3-small`, set **Model Type** to **Embedding**, then click **Test Connection**.
2. To use reranking, add a reranking model, for example `qwen3-reranker-0.6b`, set **Model Type** to **Reranking**, then click **Test Connection**.
3. Open **Settings → Knowledge Base**. Under **Retrieval models**, set **Embedding Model** to the embedding model you added. If you added a reranking model, set **Reranking Model** to it as well.
If an embedding or reranking model is not in the model list, type the full model ID in the search box, then click **Use "model ID"**.
After you change the embedding model, recalculate the knowledge base vectors so that all vectors in the knowledge base are generated by the same model.
FAQ
**What should I do if AIHubMix is missing from the model platform list?**
Check your network connection, then close the settings window and reopen **Model Services**. NoteGen fetches the platform list again. You can also click **Add custom platform** at the bottom of the **Model platforms** list, rename the platform to `AIHubMix`, set **API endpoint** to `https://aihubmix.com/v1`, then enter your API Key and add models.
**What should I do if the connection test fails?**
Check that the API Key is complete, the **API endpoint** is `https://aihubmix.com/v1`, the model ID matches the AIHubMix model list, and the **Model Type** matches the model's capability. For a `401` or `403` error, check the API Key and account permissions. For a `404` error, check the API endpoint and model ID. If the primary endpoint is temporarily unavailable, change the **API endpoint** to `https://api.inferera.com/v1`.
**What should I do if a model I added does not appear in the model selector at the bottom?**
The model selector only shows models whose **Model Type** is **Chat**. Go back to **Settings → Model Services** and confirm that the model has a model ID and that its **Model Type** is **Chat**.
**What should I do if the chat input shows "No primary model configured, can't use AI chat..."?**
Click the model name on the right side of the status bar at the bottom of the window, then select a chat model under the **AIHubMix** group.
