A custom provider extension that exposes ZAI-family models from two upstream hosts:

• Cerebras-hosted models (requires CEREBRAS_API_KEY)
• ZAI-hosted models (requires ZAI_API_KEY)

Model availability is determined strictly by which provider API keys are present.

# Install globally
pi install git:github.com/vedang/pi-custom-provider-zai

# Or install for just the current project
pi install -l git:github.com/vedang/pi-custom-provider-zai

• Key-based model availability
  • CEREBRAS_API_KEY => Cerebras model set
  • ZAI_API_KEY => ZAI model set
  • Both keys => both model sets
• Model-driven endpoint routing
  • zai-custom/<model-id> is enough to choose the right base URL and API key
• Reasoning + sampling knobs
  • Supports temperature, top_p, and clear_thinking

When invoking the provider, you can pass these options:

• temperature: Sampling temperature (0.0-2.0)
• top_p: Nucleus sampling parameter
• clear_thinking: Whether to clear thinking output

The provider is registered as zai-custom.
