PartyGraph - Meta Llama 4 Hackathon NYC Top 6 Finalist

Built for the Llamacon NYC Hackathon ([06/01/2025]). https://cerebralvalley.ai/e/llama-4-hackathon-nyc-f673085d

PartyGraph: new york central event finder, powered by Llama.

The Problem

• Platforms like Eventbrite and DoNYC prioritize large, ticketed, or sponsored events, burying smaller, community-driven gathering. Small events are hard to find unless you're in-the-know.
• Users can’t find events that “feel” right—search is limited to keywords, categories, or dates.
• Events are presented in isolation, with no sense of how they relate to others or fit into a broader cultural landscape.

Core Features

• Graph-Based Event Discovery: Circular event nodes and rectangular tag nodes visualized in a dynamic semantic graph.
• LLaMA 4 Integration:
  • Parses raw flyer images, URLs, or text into structured event data.
  • Generates tags, summaries, and vibe-based associations using long-context understanding.
• Natural Language Search: Discover events by describing your mood or past preferences.
• Democratized Event Landscape: No hierarchy—grassroots events and major festivals live in the same visual space.

Tech Stack

• Backend / Data: Typescript, Meta LLaMA 4 API (multimodal + semantic search), Perplexity Search (Data Scraping)
• Frontend: Next.js, Tailwind CSS, PostCSS
• Deployment: Vercel
