Phase 6 Plan 3: Custom Model Parameters Summary

Dynamic model parameters fetched from provider schemas, enabling seed, steps, guidance, and other model-specific inputs

Performance

• Duration: 5 min
• Started: 2026-01-10T09:39:02Z
• Completed: 2026-01-10T09:44:35Z
• Tasks: 3
• Files modified: 8

Accomplishments

• Created /api/models/[modelId] endpoint for fetching model parameter schemas
• Added ModelParameter interface to type system
• Built reusable ModelParameters component with collapsible UI
• Integrated parameters into Generate and GenerateVideo nodes
• Parameters flow through workflowStore to API route to providers
• Resolved ISS-001: Generate node now adapts to model requirements

Task Commits

Each task was committed atomically:

1. Task 1: Add schema endpoint and model schema fetching - beb0af3 (feat)
2. Task 2: Add parameter UI component - 1e60f18 (feat)
3. Task 3: Pass parameters through generation pipeline - e7ebee2 (feat)

Plan metadata: (pending)

Files Created/Modified

• src/app/api/models/[modelId]/route.ts - New endpoint for fetching model parameter schemas
• src/lib/providers/types.ts - Added ModelParameter interface
• src/components/nodes/ModelParameters.tsx - New collapsible parameter inputs component
• src/types/index.ts - Added parameters field to NanoBananaNodeData and GenerateVideoNodeData
• src/components/nodes/GenerateImageNode.tsx - Integrated ModelParameters component
• src/components/nodes/GenerateVideoNode.tsx - Integrated ModelParameters component
• src/store/workflowStore.ts - Include parameters in request payloads
• src/app/api/generate/route.ts - Added logging for custom parameters

Decisions Made

• Fetch schema from provider API when model is selected (not upfront)
• Filter out internal parameters (webhook, sync_mode, etc.)
• Prioritize common parameters (seed, steps, guidance_scale, negative_prompt)
• Use 10-minute cache TTL for schema data (same as model lists)
• Collapsible "Parameters" section to keep node UI compact

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

Next Phase Readiness

• Model parameters feature complete
• ISS-001 resolved
• Ready for next plan (06-04)
