Episode notes
Value of Vibes-Based Evaluation
- Don't just rely on aggregate metrics; examine individual examples to understand model behavior.
- "Vibes-based evaluation" can be valuable, especially for new people in ML.
Vibes Influence User Experience
- LLMs' "vibes", encompassing style, tone, and behavior, significantly impact user experience.
- Different vibes suit different contexts, like concise answers for problem-solving vs. friendly explanations for teaching.
Verbosity as a Behavioral Trick
- OpenAI models' verbosity is a behavioral trick, not a bug.
- Lengthy explanations, like restating the question and outlining the thought process, improve accuracy but sacrifice conciseness.
