Trailhead calls llama-3.3-70b-versatile — Meta's open-weight model — through Groq's free tier. No subscription, no per-hike fee, no vendor lock-in. Swap in any open model (Mixtral, Qwen, DeepSeek) by changing one string. The whole app is one HTML file: no build step, no server, works from a phone on the trailhead parking lot.
