Looking for an OpenCode extension for VS Code? Want to find free AI models you can use in your editor? OpenCode Fusion brings the models and agents you already use with OpenCode into the native VS Code Chat model picker.
Browse compatible OpenCode models—including free options when your configured providers offer them—then chat without leaving VS Code. OpenCode Fusion connects VS Code Chat to your local OpenCode CLI; it does not bundle models or provide inference credits.
What you get
OpenCode models in VS Code Chat. Pick a model from VS Code's native chat model selector. OpenCode's native models and eligible connected providers are shown together.
Free model discovery. Find available free and zero-cost OpenCode model options in the picker and dashboard. Free availability, usage limits, and terms depend on the model provider and your account.
OpenCode agents, tools, and MCPs. Keep using the agents and tool integrations configured in OpenCode, including supported file and terminal work.
Live visibility. Follow model output, reasoning and tool activity in chat, with token and cost estimates in the OpenCode Fusion dashboard.
A server managed for you. The extension starts and monitors a local opencode serve process, so you don't need to launch the server yourself.
Use your existing setup. Connect providers in OpenCode, select an agent, and optionally configure the CLI path or server settings in VS Code.
Use your existing OpenCode configuration and stay in the editor for coding questions, project work, and agent-assisted tasks.
