OpenCode setup (Grok 4.5)

​

Recommended settings

​

1. Set API key

$env:ARONA_API_KEY = "sk-xxxxxxxx"

export ARONA_API_KEY="sk-xxxxxxxx"

​

2. Edit OpenCode config

# Windows
%USERPROFILE%\.config\opencode\opencode.json

# macOS / Linux
~/.config/opencode/opencode.json

​

Recommended config

{
  "$schema": "https://opencode.ai/config.json",
  "model": "arona/grok-4.5",
  "provider": {
    "arona": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "Arona API",
      "options": {
        "baseURL": "https://sub2api.lingshichat.top/v1",
        "apiKey": "{env:ARONA_API_KEY}"
      },
      "models": {
        "grok-4.5": {
          "name": "Grok 4.5 (Arona)"
        }
      }
    }
  }
}

• model is providerID/modelID → arona/grok-4.5
• options.baseURL must include /v1
• Use {env:ARONA_API_KEY} so secrets stay out of git

​

Option B: /connect

1. Define provider.arona (npm, baseURL, models)
2. Run /connect if your version supports custom providers
3. /models → arona/grok-4.5

​

3. Verify

opencode
opencode run "Introduce yourself in one sentence"

/models

curl https://sub2api.lingshichat.top/v1/models \
  -H "Authorization: Bearer $ARONA_API_KEY"

​

Notes

• Include /v1 in baseURL
• Model IDs must match GET /v1/models for your key
• Never commit plaintext keys; use {env:...}
• Optional: whitelist: ["grok-4.5"] on the provider
