# Trivia Tournament

> A free AI-powered demo that runs a single-elimination trivia tournament on any topic you pick. Sixteen questions, one champion — every round the model generates fresh questions, scores the player, and the highest scorer advances.

## What it does

You pick a topic (any subject, any specificity — "90s hip-hop", "Mongol naval battles", "rust async internals") and a difficulty (Easy / Medium / Hard). The model generates a 16-question single-elimination bracket:

1. **Round of 16** — model writes 2 fresh questions on your topic; you answer; higher score advances
2. **Quarterfinals** — new pair of questions on the same topic
3. **Semifinals** — harder pair
4. **The Final** — single hardest question; winner gets a crown
5. **Tournament Recap** — accuracy, streaks, funniest wrong answers, what you got right about the topic

After every match, the model explains the correct answer for anything you got wrong, so the bracket doubles as a learning loop. Switch the UI between English, 繁體中文, 简体中文, and 日本語.

## Stack

- Single `index.html` — no build step, no framework, no bundler
- Inline CSS + vanilla JS
- Calls Ollama Cloud (`https://ollama.com/v1`) via a small server proxy that strips CORS
- Default model: `glm-5.2` (multilingual reasoning model, strong at on-the-fly question generation)
- `shared/i18n.js` for the 4-language UI
- `shared/ollama-stream.js` for the SSE parser (handles both `delta.reasoning` and `delta.content`)
