The explainer covers the full recommendation pipeline in plain language, with interactive elements throughout:
- Pipeline walkthrough — all 7 stages from query hydration to final selection, with expandable detail for each step
- Score simulator — drag sliders for engagement probabilities (likes, replies, shares, blocks, reports…) and watch the predicted feed score update live
- Attention mask visualizer — shows exactly how the Phoenix transformer's candidate isolation works
- Filter reference — all 15 content filters, their stage, and what they remove
- Component breakdown — Thunder, Phoenix, Grox, Home Mixer, and the Candidate Pipeline framework
- Key insights — practical takeaways about what the algorithm actually optimises for
- May 2026 changelog — everything new in this release
Everything runs in the browser with no dependencies, no build step, and no tracking.
