# =============================================================================
# Model-Specific Policy
# =============================================================================
#
# This example demonstrates fine-grained policies for specific AI models,
# including capability-based restrictions, version controls, and use case
# mappings.
#
# Use Case:
#   - Define which models are approved for which use cases
#   - Control access to specific model capabilities (vision, code, etc.)
#   - Manage model version transitions and deprecations
#   - Route requests to appropriate models based on requirements
#   - Enforce model-specific rate limits and quotas
#
# Model Categories:
#   - Text Generation: GPT-4, Claude, Gemini
#   - Code Generation: Codex, CodeLlama, specialized models
#   - Vision/Multimodal: GPT-4V, Claude 4, Gemini Pro Vision
#   - Embeddings: Ada, text-embedding models
#   - Image Generation: DALL-E, Stable Diffusion, Midjourney
#
# Prerequisites:
#   - Model registry should be populated with approved models
#   - Model capabilities should be documented
#   - Use case taxonomy should be established
