OpenCode

Connect OpenCode to XycAi through an OpenAI-compatible provider for terminal-based coding workflows.

One-click setup with our desktop client

Download the XycAi client to install and configure everything automatically — no manual steps needed.

Connection values

Create or edit opencode.json in your project and add XycAi as a custom provider:

{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "xycai": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "XycAi",
      "options": {
        "baseURL": "https://apicdn.xyc.ai/v1",
        "apiKey": "sk-xxxxxxxx"
      },
      "models": {
        "deepseek-v4-pro": { "name": "deepseek-v4-pro" }
      }
    }
  },
  "model": "xycai/deepseek-v4-pro"
}

Verify the connection

Start opencode, select xycai/deepseek-v4-pro, and send a test prompt.

Troubleshooting

Model names must match the model square exactly.
Keep the key in a local file and never commit it to Git.
