Framework · OpenAI Chat

| Format | Where to set it up |
| --- | --- |
| OpenAI Chat | llama-index-llms-openai-like package, OpenAILike(api\_base=..., api\_key=..., model=..., is\_chat\_model=True) class |

## [](https://ailoot.ai/docs/en/integrations/llamaindex/#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.

```bash
pip install llama-index-llms-openai-like
```

```python
import os
from llama_index.llms.openai_like import OpenAILike
llm = OpenAILike(
    model="deepseek-v4-pro",
    api_base="https://api.ailoot.ai/v1",
    api_key=os.environ["AILOOT_API_KEY"],
    is_chat_model=True,
    is_function_calling_model=True,
    context_window=128000)
print(llm.complete("Hello"))
```

Example model: `deepseek-v4-pro, claude-sonnet-5-5, gpt-6.1-sol`. 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/llamaindex/#notes)Good to know

Use a URL with /v1. is\_chat\_model=True is required; otherwise, the class uses the legacy /completions endpoint. Set is\_function\_calling\_model=True so agents can use tools. Set context\_window according to the model card in the Ailoot catalog.

## [](https://ailoot.ai/docs/en/integrations/llamaindex/#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/).
