Phase 01-02: Provider Abstraction Summary

Provider abstraction interfaces and registry for unified access to Gemini, Replicate, and fal.ai

Performance

• Duration: 2 min
• Started: 2026-01-09T02:35:42Z
• Completed: 2026-01-09T02:38:05Z
• Tasks: 2
• Files created: 2

Accomplishments

• Created provider abstraction interfaces defining how providers expose model discovery and generation
• Established ProviderInterface contract that all providers will implement
• Built provider registry with self-registration pattern for dynamic provider discovery
• Phase 1 complete - ready for Phase 2: Model Discovery

Task Commits

Each task was committed atomically:

1. Task 1: Create provider abstraction interfaces - 8b49db4 (feat)
2. Task 2: Create provider registry and factory - c8618ab (feat)

Files Created/Modified

• src/lib/providers/types.ts - Provider abstraction interfaces (ProviderModel, ProviderInterface, GenerationInput/Output, ModelCapability)
• src/lib/providers/index.ts - Provider registry with registerProvider(), getProvider(), getConfiguredProviders(), getAllProviders()

Decisions Made

• Used self-registration pattern where provider modules call registerProvider() on import
• Gemini provider remains special-cased in /api/generate route; may migrate in future phase
• Types exported from both files for convenient imports via "@/lib/providers"

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

• npm run lint has pre-existing configuration issue (missing eslint.config.js for ESLint v9). This is not related to this plan's changes. Build passes successfully.

Next Phase Readiness

• Provider abstraction layer complete with all interfaces defined
• Registry ready to accept provider registrations from Phase 2
• Phase 1 (Provider Infrastructure) complete
• Ready for Phase 2: Model Discovery (Replicate and fal.ai implementations)
