# AI Photo Edit - Environment Configuration
# =============================================================================
#
# SETUP INSTRUCTIONS:
#   1. Copy this file to .env:  cp .env.example .env
#   2. Get API key from Replicate (see below)
#   3. Paste your key in the REPLICATE_API_KEY line
#   4. Rebuild: docker-compose up -d --build
#
# =============================================================================


# =============================================================================
# STEP 1: Choose AI Provider
# =============================================================================
# Options: mock, openai, stability, replicate
#
#   mock      = Free, but returns original image unchanged (for testing UI)
#   openai    = DALL-E 2 inpainting (~$0.02/image) - lower quality
#   stability = Stability AI SDXL (~$0.01/image) - good quality
#   replicate = Multiple models (~$0.002-0.03/image) - RECOMMENDED
#
# RECOMMENDED: Use "replicate" for best quality and model variety
# =============================================================================

AI_PROVIDER=replicate

# STEP 2: Get Your API Key

# STEP 3: Model Selection (OPTIONAL - for advanced users)
# =============================================================================
#
# By default, the system AUTO-SELECTS the best model based on your prompt:
#   - Prompt contains "remove/erase/delete" → Uses LaMa (fast removal)
#   - Prompt contains "face/hands/person"   → Uses Realistic Vision
#   - Everything else                       → Uses SDXL Inpaint
#
# To FORCE a specific model, uncomment ONE line below:
# ───────────────────────────────────────────────────────────────────────────

# REPLICATE_MODEL=sdxl-inpaint      # General purpose, good quality (~$0.01)
# REPLICATE_MODEL=lama              # Object removal ONLY (~$0.002, fastest)
# REPLICATE_MODEL=realistic-vision  # Faces, hands, skin (~$0.02)

# ───────────────────────────────────────────────────────────────────────────
# IMPORTANT: About Flux and other text-to-image models
# ───────────────────────────────────────────────────────────────────────────
#
# Models like "black-forest-labs/flux-kontext-pro" are TEXT-TO-IMAGE models.
# They generate NEW images from text, they DON'T edit existing images.
#
# For EDITING (inpainting), you need models that accept:
#   - An existing image
#   - A mask showing what to change
#   - A prompt describing the change
#
# WORKS for editing:        DOESN'T work for editing:
#   ✓ sdxl-inpaint           ✗ flux-kontext-pro (text-to-image)
#   ✓ lama                   ✗ flux-dev (text-to-image)
#   ✓ realistic-vision       ✗ ideogram (text-to-image)

# TROUBLESHOOTING
# =============================================================================
#
# PROBLEM: "405 Method Not Allowed" errors
# FIX:     Rebuild container: docker-compose build --no-cache && docker-compose up -d
#
# PROBLEM: "REPLICATE_API_KEY not configured"
# FIX:     1. Make sure .env file exists (not just .env.example)
#          2. Make sure REPLICATE_API_KEY has your actual key
#          3. Restart: docker-compose down && docker-compose up -d
#
# PROBLEM: Edits don't change the image
# FIX:     Check AI_PROVIDER isn't set to "mock"
#
# PROBLEM: "rembg not installed"
# FIX:     Rebuild: docker-compose build --no-cache backend
#
# PROBLEM: Smart Select uses flood-fill instead of AI
# FIX:     Smart Select needs REPLICATE_API_KEY for SAM model
#
# CHECK LOGS: docker-compose logs -f backend
