The **Researcher** uses an open-weight model to read that messy page text and pick out the correct price as structured JSON. The **Reporter** then turns the Python-computed (guaranteed-correct) price comparison into natural-language email copy. - **Model:** [`openai/gpt-oss-20b`](https://huggingface.co/openai/gpt-oss-20b) by default — Apache-2.0 licensed, genuinely open-source weights, not just "open" in name. Hosted **for free** by [Groq](https://console.groq.com) (no credit card required) on their own hardware, not a closed/proprietary model API. Swap `GROQ_MODEL` for any other model Groq hosts for free (`llama-3.3-70b-versatile`, `qwen/qwen3-32b`, `openai/gpt-oss-120b`, etc.). - **Browser tool:** [Browser MCP](https://github.com/browsermcp/mcp) — Apache-2.0, runs entirely on your machine, free. ## Demo mode vs. production Thi
