mixtape-core 0.4.0

//! Pre-configured model definitions
//!
//! This module contains model structs for various LLM providers.
//! Each model implements the `Model` trait and provider-specific traits
//! like `BedrockModel` or `AnthropicModel`.
//!
//! Models are organized by vendor:
//! - `claude` - Anthropic Claude models
//! - `cohere` - Cohere models
//! - `deepseek` - DeepSeek models
//! - `glm` - Z.AI GLM models
//! - `google` - Google models
//! - `kimi` - Moonshot Kimi models
//! - `llama` - Meta Llama models
//! - `minimax` - MiniMax models
//! - `mistral` - Mistral AI models
//! - `nova` - Amazon Nova models
//! - `qwen` - Alibaba Qwen models

/// Macro to generate model structs with trait implementations
///
/// This macro creates a model struct that implements:
/// - `Model` trait (always)
/// - `BedrockModel` trait (always)
/// - `AnthropicModel` trait (if `anthropic_id` is provided)
///
/// Optional fields:
/// - `anthropic_id` - Anthropic API model ID (enables AnthropicModel trait)
/// - `default_inference_profile` - Default inference profile for Bedrock (e.g., Global)
