CoreInfra OpenCode Plugin

Plugin for OpenCode that adds CoreInfra AI Hub as an external model provider.

Installation

Works with OpenCode 1.x (1.4.0 or newer) and OpenCode 2.x (2.0.28 or newer).

OpenCode 2

Install the plugin

opencode plugin add '@coreinfra/opencode-plugin@latest'

Log in by entering the API token

opencode auth login coreinfra

OpenCode 1

Install the plugin

opencode plugin -g '@coreinfra/opencode-plugin@latest'

Log in by entering the API token

opencode providers login --provider coreinfra

During authentication, you will need a CoreInfra AI Hub API token.

Features

• Up-to-date model list - the catalog is loaded dynamically from the Hub API on every startup and always reflects its current state. Model capabilities (context limits, reasoning, tool use, etc.) are resolved from the models.dev catalog.
• All available models - every model exposed by the Hub is supported.
• Reasoning support - interleaved thinking mode is enabled automatically where applicable.

Limitations

At the moment, OpenCode supports prices in USD only. Because of that, pricing is not overridden yet: OpenCode shows prices from the original OpenAI/Anthropic API.

Usage

After installation and authentication, models will be available with the coreinfra/ prefix:

opencode run -m coreinfra/gpt-5.4-nano
opencode run -m coreinfra/claude-sonnet-4-20250514

To see the full list of available models:

opencode models coreinfra

Supported Models

The full model list is determined by the Hub contents at startup time. The plugin supports all models listed on this page: https://hub.coreinfra.ai/pricing

Configuration

Environment Variables

Variable	Default	Description
COREINFRA_API_KEY	—	On OpenCode 2, an API token to use instead of logging in (a saved login takes precedence). On OpenCode 1 it only authenticates loading the model list; logging in is still required.
COREINFRA_HUB_BASE_URL	https://hub.coreinfra.ai	Base URL of the CoreInfra Hub instance. Overrides the default endpoint for model listings and API proxying.
