Cursor - concentrate

Why Use Concentrate with Cursor?

By routing Cursor through Concentrate, you get centralized visibility and control over your team’s AI usage, all in one place. Track spend and receive token credits (saving you money), set budget limits, and access models from our catalog that Cursor doesn’t natively offer without changing your workflow. Everything is visible in your Concentrate dashboard in real time.

Supported Cursor Modes

Concentrate works with the following Cursor modes:

Mode	Status	Notes
Chat	Supported	Fully functional with all models on Concentrate
Composer	Supported	Works with models that support tool use
Agent	Supported	Works with models that support tool use
Tab Autocomplete	Not supported	Cursor routes autocomplete through its own backend

Prerequisites

Before you begin, ensure you have:

A Concentrate AI account with an active API key (starts with sk-cn)
Cursor installed and updated to the latest version

Setup

Open Cursor model settings

Open Cursor Settings (Cmd+, on macOS or Ctrl+, on Windows/Linux), then click the Models tab in the sidebar.

Cursor settings sidebar with Models selected, required fields highlighted — Enable custom OpenAI base URL and OpenAI API Key at highlighted areas

Set the Override OpenAI Base URL field to:

https://api.concentrate.ai/v1

Then set the OpenAI API Key field to your Concentrate AI API key.

Add Concentrate AI models

Navigate to just above the API keys dropdown, and click View All Models.

Cursor 'View All Models' button highlighted — Click 'View All Models'

Now let’s add some models from Concentrate:

Cursor 'Add Custom Model' button highlighted — Click 'Add Custom Model'

When prompted, input any provider/model slug, such as:

anthropic/claude-sonnet-4-6

You can repeat this step to add as many models as you like using the same provider/model format. Refer to the models endpoint for a full list of available models and their providers.

Switching Between Concentrate and Cursor

Once you have set Concentrate as your OpenAI Base URL, you can switch between Concentrate and Cursor’s native model access from the same Models settings page by toggling OpenAI API Key:

On: use Concentrate
Off: use Cursor’s native model access

Leave Override OpenAI Base URL as is with the api.concentrate.ai/v1 in place

Verify Configuration

Open a new Cursor chat, select one of your custom models from the model dropdown, and run a quick prompt to test that it’s working. If the response comes back successfully, your setup is working.

Troubleshooting

Authentication failed

Confirm your Concentrate API key is valid and fully pasted in the OpenAI key field. The key should start with sk-cn.

Connection or endpoint errors

Verify the base URL is exactly https://api.concentrate.ai/v1 with no trailing slash or extra spaces.

Models not appearing or not responding

Re-open Cursor Settings (Cmd+, / Ctrl+,) and confirm your custom models are listed and enabled
Make sure the model slug matches the provider/model format exactly (e.g. anthropic/claude-sonnet-4-6) not just model (e.g., claude-sonnet-4-6)
Restart Cursor and test again

Tab autocomplete not working

Cursor routes tab autocomplete through its own backend, not the custom OpenAI base URL. Concentrate AI does not support Cursor’s autocomplete feature at this time.
