Phase 5 Plan 2: Provider Image Integration Summary

img2img support for Replicate and fal.ai via automatic image URL conversion with cleanup

Performance

• Duration: 2 min
• Started: 2026-01-09T09:51:03Z
• Completed: 2026-01-09T09:53:44Z
• Tasks: 3
• Files modified: 1

Accomplishments

• Replicate predictions receive image input via image parameter
• fal.ai requests receive image input via image_url parameter
• Large images (>256KB) automatically converted to temporary URLs
• Uploaded images cleaned up immediately after provider call completes
• Small images pass efficiently as data URIs

Task Commits

Each task was committed atomically:

1. Task 1: Update generateWithReplicate to pass image input - 4477f6f (feat)
2. Task 2: Update generateWithFal to pass image_url parameter - 6324af3 (feat)
3. Task 3: Upload images to URL server with cleanup - 2195a6e (feat)

Plan metadata: (pending)

Files Created/Modified

• src/app/api/generate/route.ts - Added image parameter passing and URL conversion logic

Decisions Made

• Use image parameter for Replicate (most common for img2img models, future enhancement could detect from model schema)
• Use image_url parameter for fal.ai (consistent across all fal.ai models)
• Small images use data URIs directly for efficiency
• Gemini path unchanged (it handles base64 directly without URL conversion)

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

Next Phase Readiness

• Phase 5 complete: Image URL server infrastructure fully integrated
• Ready for Phase 6: Video & Polish
