Use Cline with Models Hub: OpenAI Compatible and Anthropic Setup

Connect the VS Code extension Cline to Models Hub via either OpenAI Compatible or Anthropic provider, with field details, verification steps, and error troubleshooting.

Cline is a VS Code extension that acts as an autonomous coding agent: it reads and writes files, runs terminal commands, and plans multi-step tasks on its own. You can swap its model source for any compatible service. Point the provider at Models Hub and Cline's chat, code generation, and terminal actions all draw on your Models Hub balance. This page covers the connection only, not how to use Cline itself.

Three things you need

A Models Hub API key, a base URL (differs by method, see below), and a model name. Pick one of the two providers below.

Prerequisites

Cline installed. Search "Cline" in the VS Code Extensions marketplace, or see the official docs.
A Models Hub API key from the Tokens page, in a group that can access the models you want.

Recommended models

Use case	Model	Pricing	Live status
Everyday coding, best balance of speed and quality	`claude-sonnet-4-6`	Price	Availability and latency
Complex refactors and long tasks	`claude-opus-4-6`	Price	Availability and latency
Cheap and fast for small edits	`claude-haiku-4-5`	Price	Availability and latency

Model names are authoritative on the pricing page.

Setup

Open settings via the gear icon in the top-right of the Cline panel, or run Cline: Open In New Tab from the command palette (Cmd/Ctrl+Shift+P) for a full tab. Pick either provider below in the API Provider dropdown.

Option 1: OpenAI Compatible (recommended for flexibility across vendors)

Set API Provider to "OpenAI Compatible".
Enter the Base URL:
```
https://modelsok.com/v1
```
Paste your Models Hub key into API Key.
Enter the model name in Model, e.g. claude-sonnet-4-6. Note: Cline's own docs label this field "Model", though some versions show "Model ID" in search summaries; trust the control you actually see in your version.

Option 2: Anthropic (simpler if you only use Claude models)

Set API Provider to "Anthropic".
Enable "Use custom base URL" and enter:
```
https://modelsok.com
```
Note this path does not include /v1, unlike Option 1.
API Key and Model work the same way; use a Claude model name such as claude-sonnet-4-6.

Verify

Ask Cline something like "describe this project in one sentence". A normal reply with no error dialog means you're connected. Then check Usage logs in the Models Hub console; a request under your configured model name appears within seconds, confirming traffic went through Models Hub.

Common errors

Symptom	Cause	Fix
`401` / `Invalid API key`	Incomplete key, stray whitespace, or a disabled token	Re-copy from the Tokens page
No response, or a connection error	Wrong base URL, most often mixing up `/v1` between the two options	OpenAI Compatible uses `https://modelsok.com/v1`; Anthropic uses `https://modelsok.com` with no `/v1`
`model not found` / model unavailable	Misspelled model name, or the token's group can't access it	Check the pricing page
`429`	Rate limited by concurrency	Retry shortly; contact support for a higher limit if it persists
Nothing shows in usage logs	Wrong provider selected, or settings weren't saved	Reopen settings and confirm Provider, Base URL, and Key are all saved

FAQ

How is it billed? Per input and output token actually consumed, at the price on each model's pricing page. Usage logs itemize every request.

Which provider should I pick? Anthropic is simpler if you only use Claude models, since the base URL skips /v1. Pick OpenAI Compatible if you might mix in other vendors' models later. Both draw from the same Models Hub account and balance.

How do I switch models? Edit the Model field in settings and save, or use the model picker at the top of the Cline chat panel if your version has one.
