Module models 

Model definitions for LLM providers.

This module provides type-safe model identifiers for Anthropic Claude, Google Gemini, and OpenAI models. Using enums prevents typos and ensures only valid model names are used.

Design Philosophy

• Type Safety: Enums prevent invalid model names at compile time
• Flexibility: Custom variant allows new models without code changes
• Validation: Custom models are validated by prefix on conversion
• Dual Names: Both API IDs and CLI shorthand names are supported

Future Direction

This module will evolve to support capability-based model selection:

Model::query()
    .provider(Provider::Any)
    .tier(Tier::Fast)
    .with_capability(Cap::Vision)
    .max_budget_per_1k(0.01)
    .select()
