#OpenCode

An open-source terminal agent with multi-model switching; connects to ByteSeek via the OpenAI-compatible protocol.

#Install

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

npm install -g opencode-ai

brew install sst/tap/opencode

Website: opencode.ai.

#Prerequisites

• OpenCode installed (opencode --version prints a version)
• An OpenAI-format group key from the API Keys page

#Configure

Edit OpenCode's config (~/.config/opencode/opencode.json) and add a custom provider:

{
  "provider": {
    "byteseek": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "ByteSeek",
      "options": {
        "baseURL": "https://tokens.byteseek.ai/v1",
        "apiKey": "sk-your-key"
      },
      "models": {
        "claude-sonnet-4": { "name": "Claude Sonnet 4" },
        "deepseek-v3": { "name": "DeepSeek V3" }
      }
    }
  }
}

List the models you want under models, with IDs from the model plaza; with a composite key, include the prefix.
