What’s new?
- Fewer hallucinations: Leo now more consistently avoids transcription errors like repeated or invented text, especially at the end of documents
- More complete outputs: Significantly fewer blank pages and skipped lines, giving you fuller, more faithful transcripts
- Smarter formatting: Enhanced recognition of structured layouts, including tables, margin notes, and other non-linear text features
- Better with books: Improved performance on double-page spreads and printed texts that previously caused issues
What’s next?
- Support for later medieval manuscripts (c. 1100–1500) written in Latin scripts
- Improved transcription accuracy for modern European languages, including French, German, Italian, and more
- More robust handling of damaged, distorted, or rotated images, enabling reliable transcription even in more challenging cases
