Cline

Cline is a VS Code extension that plans and edits code with your approval at each step. Its OpenAI Compatible provider accepts any endpoint, so NextModel is one form away.

Quick start

  1. Get your NextModel API Key

    Create a key in the NextModel console — Cline will send it with every request.

  2. Install the Cline extension in VS Code

    Or search for Cline in the Extensions view and install it there.

    Official docs

    Shell
    code --install-extension saoudrizwan.claude-dev

  3. Choose OpenAI Compatible and fill in the provider fields

    In Cline's settings set API Provider to OpenAI Compatible (not OpenAI), Base URL to https://api.nextmodel.app/v1, API Key to your NextModel key, and Model ID to claude-sonnet-4-5.

  4. Give Cline a first task

    Start a task in the Cline panel — requests are billed to your NextModel key.

Example prompts

Prompts
Create a REST endpoint for password reset, including tests and error handling.
Scan the repository for TODO comments and group them by module with a short plan for each.

FAQ

I don't see a Base URL field

That field only appears for the OpenAI Compatible provider. Switch from OpenAI to OpenAI Compatible at the top of the provider form.

Which Model ID should I type?

The exact ID your endpoint serves — claude-sonnet-4-5 for this guide. Cline sends the string as-is.

Who bills the requests?

Every call goes to your base URL with your key, so usage lands on your NextModel account rather than a provider plan inside Cline.

Troubleshooting

401 or 403 in the Cline log

The key field easily keeps a stale value. Re-paste your key, save, and retry the task.

Model not found errors

The Base URL must include /v1 and the Model ID must match exactly — both mistakes surface as model-not-found from the endpoint.

Codex CLI

OpenAI's terminal coding agent, pointed at NextModel.

Codex CLI reads model providers from ~/.codex/config.toml. Add one provider block that points at your NextModel base URL, export your key, and every codex run routes through NextModel.

Cursor

The AI-first IDE, wired to your own endpoint.

Cursor supports bring-your-own-key for OpenAI-compatible endpoints. Paste your NextModel key under Settings → Models and point the OpenAI provider's base URL at NextModel so OpenAI-format requests go there.

Cherry Studio

A desktop chat client that speaks OpenAI out of the box.

Cherry Studio manages model providers as services. Add NextModel once as an OpenAI-compatible provider and it sits next to the services you already use.

OpenAI SDK

Any OpenAI SDK, one base_url away.

The official OpenAI SDKs for Python and Node accept a custom endpoint. Set base_url to your NextModel endpoint, keep the key in the environment, and the rest of your code stays unchanged.
