CoreInfra OpenCode Plugin

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

Installation

Important: requires OpenCode version 1.4.0 or newer

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.
• OpenAI and Anthropic models - both model families are supported, including GPT-5.x and Claude 4.x.
• Reasoning support - interleaved thinking mode is enabled automatically for Anthropic models.

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
