Why OpenCode

OpenCode is an open-source coding agent available in the terminal, IDE, and desktop app.

• Automatically loads the appropriate LSP servers

• Works with different models and providers
• Available in the terminal, IDE, and desktop app

Official OpenCode documentation ↗

1. Install OpenCode

Run the official installer in your terminal:

curl -fsSL https://opencode.ai/install | bash

2. Open the configuration

The global OpenCode config lives in your home directory. Create it if it does not exist:

mkdir -p ~/.config/opencode && $EDITOR ~/.config/opencode/opencode.jsonc

For project-only settings, create opencode.json or opencode.jsonc in the repository root instead.

3. Add the Anthropic provider

Paste the configuration below and replace sk-cs2-YOUR_API_KEY with a key generated in your Claude API Tech dashboard. If the file already contains settings, merge in the provider section.

{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "anthropic": {
      "options": {
        "baseURL": "https://api.llm-gate.tech/v1",
        "apiKey": "sk-cs2-YOUR_API_KEY"
      }
    }
  }
}

4. Start OpenCode

Open your project directory and start OpenCode. Then select the Claude model you want to use.
