Code editor · OpenAI Chat

| Format | Where to set it up |
| --- | --- |
| OpenAI Chat | Preferences → AI-features → OpenAiCustom, or the ai-features.openAiCustom.customOpenAiModels key in settings.json; open AI Configuration with Alt+A. |

## [](https://ailoot.ai/docs/en/integrations/theia/#setup)Setup

Copy the configuration and replace `sk-...` with your key from the Ailoot Dashboard. Prefer storing the key in the environment variable `AILOOT_API_KEY`, if the application supports it.

Before starting, request GET /v1/models with your Ailoot key. Choose an exact model ID whose methods include POST /v1/chat/completions, then use that ID in the configuration. For agents, also check tool support and the features required by your client version.

```json
{
  "ai-features.openAiCustom.customOpenAiModels": [
    {
      "model": "claude-sonnet-5-5",
      "url": "https://api.ailoot.ai/v1",
      "id": "ailoot-claude-sonnet-5-5",
      "apiKey": "sk-...",
      "developerMessageSettings": "system"
    }
  ]
}
```

Example model: `claude-sonnet-5-5`. Choose any other model from the [catalog](https://ailoot.ai/models/en/) — check that it supports the format you need.

## [](https://ailoot.ai/docs/en/integrations/theia/#notes)Good to know

url is the base URL ending in /v1. For models not from OpenAI, developerMessageSettings: "system" is the safe choice.

## [](https://ailoot.ai/docs/en/integrations/theia/#check)Test

- For the OpenAI format, the URL is `https://api.ailoot.ai/v1` (or the full path if the application asks for a full URL).
- Ask a short question. If you get an error, check the code and Request ID, then consult [Errors and limits](https://ailoot.ai/docs/en/errors/).
- 404 immediately after setup almost always means the URL is wrong: an extra or missing `/v1`.
- 402 — insufficient balance for the reserve. Agents reserve more than chat: [why](https://ailoot.ai/docs/en/billing/reserve/).
