Provider Discounts

Apply percentage-based discounts to specific providers. This is useful for negotiated enterprise pricing with providers.

Usage with LiteLLM Proxy Server​

Step 1: Add discount config to config.yaml

# Apply 5% discount to all Vertex AI and Gemini costs
cost_discount_config:
  vertex_ai: 0.05  # 5% discount
  gemini: 0.05     # 5% discount
  openrouter: 0.05 # 5% discount
  # openai: 0.10   # 10% discount (example)

Step 2: Start proxy

litellm /path/to/config.yaml

The discount will be automatically applied to all cost calculations for the configured providers.

How Discounts Work​

  • Discounts are applied after all other cost calculations (tokens, caching, tools, etc.)
  • The discount is a percentage (0.05 = 5%, 0.10 = 10%, etc.)
  • Discounts only apply to the configured providers
  • Original cost, discount amount, and final cost are tracked in cost breakdown logs
  • Discount information is returned in response headers:
    • x-litellm-response-cost - Final cost after discount
    • x-litellm-response-cost-original - Cost before discount
    • x-litellm-response-cost-discount-amount - Discount amount in USD
