Add your Doubleword endpoint to begin accessing Doubleword’s high-throughput, low-cost models in Arize AX’s prompt playground and LLM-as-a-judge evaluations. Doubleword exposes an OpenAI-compatible API, so it is added as a Custom Model Endpoint — Arize AX makes use of the OpenAI Client to make calls to it.
By adding this integration, your data may be sent to your Doubleword deployment for certain actions within Arize AX (e.g., prompt playground) and your account may be billed for usage.

​
Add the Integration Using the Arize Skills

Add a Doubleword integration from your coding agent using the Arize Skills:

Create a custom model integration named 'my-doubleword' with my base URL https://api.doubleword.ai/v1 and API key dw-...

​
Add the Integration from Arize AX

​
Select Custom Model Endpoints from the Providers List

The AI Provider integrations tab

​
Fill Out Your Integration Details

The Doubleword integration details pane
Give your integration a name (e.g. Doubleword). Then set your base URL and API key from your Doubleword dashboard.
Enter the base URL including the version path: https://api.doubleword.ai/v1. Do not include endpoint paths like /chat/completions as these are appended automatically.
If you need to send any extra headers to every request, set these. You then need to define the available model deployments. Leave OpenAI default models off and add your Doubleword model identifiers as custom model names (e.g. deepseek-ai/DeepSeek-V4-Flash). See the Doubleword model catalog for the current list.

​
