Intelligence, upgraded. v0.7.0delivers the second major iteration of our recommendation engine alongside fully functional playlists. The brain behind Lernex just got significantly smarter, and you're about to feel the difference.

FYP Engine v0.2.0: A Smarter Teacher

The For You Page is where learning happens, and FYP Engine v0.2.0represents a complete reimagining of how recommendations work. This isn't incremental—it's a fundamental rethinking of personalized education.

What's New in v0.2.0

Multi-factor Ranking

Balances topic relevance, difficulty, and engagement history

Learning Path Awareness

Understands prerequisite relationships between topics

Adaptive Difficulty

Adjusts in real-time based on quiz performance

Novelty Injection

Occasionally surprises you with related topics you might love

The result? A feed that feels less like an algorithm and more like a great teacher who knows exactly what you need next—challenging enough to grow, approachable enough to succeed.

Playlists: From Vision to Reality

Remember when playlists were just a promise? They're now fully functional. The Playlists page is live, letting you:

  • Create — Build custom playlists from lessons you encounter
  • Manage — View and organize all playlists in one place
  • Track — Monitor progress through curated learning paths
  • Share — Playlist sharing coming soon

This is the foundation for a feature that will become central to how people use Lernex. More capabilities are coming in future releases.

Powered by Grok 4 Fast

Under the hood, level map generation now runs on Grok 4 Fast—a newer, more capable model that produces:

More coherent learning progressions
Better topic relationship understanding
Faster generation times
Higher quality prerequisite mapping

Level maps are the backbone of personalized learning. They define how concepts connect and what order makes sense for you. Grok 4 Fast generates maps that feel genuinely intuitive.

Formatting Engine Polish

The Formatting Engine—which transforms AI output into beautiful, readable lessons—has received several refinements:

  • Complex lists — Better handling of nested structures
  • Code blocks — Improved syntax highlighting
  • Transitions — Smoother flow between content types
  • Typography — More consistent spacing and sizing

Bug Fixes

Stability improvements for the playlist experience:

  • Fixed edge cases in playlist error handling
  • Resolved empty playlist save issues
  • Improved duplicate lesson detection
  • Enhanced error messages for debugging

The Road to v1.0

With FYP Engine v0.2.0 and functional playlists, we're approaching our v1.0 vision—a learning platform that truly adapts to each individual. Every update brings us closer. Thank you for being part of this journey.

Smarter learning, realized.
