The system runs Qwen 2.5:3B and Gemma 4 via Ollama with structured JSON outputs to enforce time, budget and transit constraints, falling back to mathematical routing when offline, and performs on-device image downsampling to 512px JPEGs before vision-model analysis.", "body_md": "*This is a submission for the [Hacktoberfest Open-Source AI Challenge: Week 3](https://dev.to/challenges/hacktoberfest-week3-2026-10-19).*\n\n### \n  \n  \n  🌟 Spot-Undoo v2: Open-Weight AI Travel Studio & Layover Optimizer\n\n**Spot-Undoo** is an open-source, privacy-preserving micro-travel concierge engine tailored for travelers, transit layover passengers, and explorers across Kerala's 14 districts.\n\nDuring **Week 3**, we advanced Spot-Undoo from a mobile-first app into a full-scale **Open-Source AI Desktop Studio & GPU-Accelerated Geo-Engine**, designed to deliver instant, constraint-guaranteed transit itineraries with **zero cloud inference cost**.\n\n### \n  \n  \n  🚀 What's New in Week 3 Development\n\n1. \n**🖥️ Widescreen Desktop Studio Layout (1680px)** :\n   - Complete architectural redesign away from cramped mobile layouts into a split-screen studio workstation.\n  - \n**Docked Inspection Panel** : Left-docked details card with high-resolution photography, transit breakdowns, and authentic community reviews.\n  - \n**Expanded Canvas** : Right-hand interactive Leaflet map canvas utilizing full desktop screen real estate.\n  - \n**Dual-Column Layover Assistant** : Dedicated left-side chat cockpit with right-hand live telemetry inspector.\n2. \n**⚡ GPU-Accelerated Leaflet Map (Zero Pan Lag)** :\n   - Eliminated panning and zoom stutter across large Kerala spot clusters using memoized zoom tiers and batched `L.layerGroup` .\n  - Hardware-accelerated CSS transforms (`will-change: transform; transform: translate3d(0,0,0)` ) achieving smooth 60fps rendering.\n3. \n**🧠 Open-Weight Local AI Inference (Ollama & Qwen)** :\n   - Powered by local open-weight models (**Qwen 2.5:3B / Gemma 4** ) with structured JSON outputs.\n  - Guaranteed constraint matching (max available time, strict budget limits, transit travel time).\n  - Instant mathematical fallback routing if running completely offline.\n4. \n**📸 On-Device Multimodal Verification** :\n   - HTML5 Canvas client-side downsampling to 512px JPEG before sending to vision models, keeping memory footprint low.\n  - Instant visual spot analysis with vibe tagging and authentic local tips.\n\n### \n  \n  \n  🛠️ Open-Source Tech Stack\n\n- \n**Frontend** : React 18, Vite, Tailwind CSS 3, Lucide Icons, Leaflet OpenStreetMap.\n- \n**AI Models** : Local open-weight models via Ollama (`qwen2.5:3b` ,`gemma4` ), Groq Cloud API, Google Gemini Flash.\n- \n**Maps & Data** : OpenStreetMap, Leaflet GPU acceleration, LocalStorage zero-database architecture.\n- \n**Mobile & Android** : Capacitor native Android bridge (`SpotUndoo-v1.0.apk` ).\n\n### \n  \n  \n  🔗 Open-Source Repository & Demo\n\n*Built with ❤️ for Hacktoberfest 2026 & MLH Hackathons.*", "url": "https://wpnews.pro/news/spot-undoo-v2-open-weight-ai-layover-studio-gpu-map-engine-for-kerala", "canonical_source": "https://dev.to/fm9447/spot-undoo-v2-open-weight-ai-layover-studio-gpu-map-engine-for-kerala-34f2", "published_at": "2026-10-19 18:11:54+00:00", "updated_at": "2026-10-19 18:14:49.493516+00:00", "lang": "en", "topics": ["ai-tools", "ai-products", "large-language-models", "computer-vision", "developer-tools"], "entities": ["Spot-Undoo", "Ollama", "Qwen 2.5:3B", "Gemma 4", "Leaflet", "OpenStreetMap", "Groq", "Google Gemini Flash"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/spot-undoo-v2-open-weight-ai-layover-studio-gpu-map-engine-for-kerala", "markdown": "https://wpnews.pro/news/spot-undoo-v2-open-weight-ai-layover-studio-gpu-map-engine-for-kerala.md", "text": "https://wpnews.pro/news/spot-undoo-v2-open-weight-ai-layover-studio-gpu-map-engine-for-kerala.txt", "jsonld": "https://wpnews.pro/news/spot-undoo-v2-open-weight-ai-layover-studio-gpu-map-engine-for-kerala.jsonld"}}
