Agent Free Food

🔗 Live demo: https://huggingface.co/spaces/lablab-ai-amd-developer-hackathon/AgentFreeFood

An agentic chat that finds events with free food and free drinks in any city. Type a question — the agent decides whether to chat or to run a live web search, scores each event with an LLM, and returns the best ones.

Powered by:

• AMD MI300X GPU running Qwen2.5-14B-Instruct via vLLM (OpenAI-compatible)
• Exa neural web search
• Gradio UI

How it works

1. User asks something in chat ("free food in Austin tonight").
2. The LLM decides whether to call its single tool: search_free_food(city, threshold).
3. If yes, the app runs Exa search across multiple curated queries, fetches page contents, and asks the LLM to score each event 0–100 on free-food likelihood.
4. Events at or above the threshold are streamed back into the chat as a markdown table sorted by score.
5. If no tool is needed, the LLM just chats normally.
