Providers & Models

Default: z.ai + GLM-5.1

SANDCODE ships with z.ai as the default provider and GLM-5.1 as the default model. The API client is configured in src/services/api/client.ts.

Configuration

Set your provider in user or project config:

{
  "provider": "zai",
  "model": "GLM-5.1"
}

API Key

SANDCODE checks for your API key in this order:

1. ZAI_API_KEY environment variable
2. Interactive prompt on first run (stored securely)
3. apiKey field in config

export ZAI_API_KEY=sk-your-key-here

Available models

All models are configured in src/utils/model/configs.ts. The GLM model family includes:

Model	Context Window	Notes
GLM-5.1	200K	Default, recommended
GLM-4.6	128K	Previous generation

Using other providers

SANDCODE’s provider detection (src/utils/model/providers.ts) checks environment variables and config. You can configure custom providers by setting:

export ANTHROPIC_API_KEY=sk-ant-...
# or
export OPENAI_API_KEY=sk-...

And updating your config:

{
  "provider": "anthropic",
  "model": "claude-sonnet-4-6"
}

Model context window

Context window sizes are defined in src/utils/context.ts. GLM models get 200K tokens by default.
