TripSync — A Three-Tier Gemma 4 Travel Planner Running Live on Flask

Short summary

TripSync demonstrates a three-tier AI architecture for travel planning: fast cloud inference (Groq), high-quality API mode (Gemma 4 via Gemini), and privacy-first local execution (Gemma 4 via Ollama on M1 hardware). The approach solves cost ($0 marginal per query locally) and privacy (data never leaves device). Performance: local cold start 30–45s, API response 10–15s, with silent fallback to cloud infrastructure.

• •Three-tier AI architecture (cloud/API/local) balances speed, quality, and cost per query
• •Gemma 4 enables both high-quality API responses and privacy-preserving local inference
• •Live demo and open-source code with performance benchmarks available for replication
