Episode notes
Use Clear Signals For Iteration
- Track a clear failure signal to guide model improvements and prevent regressions.
- Use measurable proxies like text rendering when human preference labels are costly or slow.
Positive Transfer Between Understanding And Generation
- Image understanding and generation positively transfer when trained together in a multimodal model.
- Visual data provides shortcuts to world knowledge that text alone may miss.
Five 1980s Glamour Variants Demo
- Nicole asked Gemini to produce five 1980s glamour mall variations and it returned consistent characterful options.
- The model labeled each variant and maintained a recognizable subject across styles.
