Episode notes
DeepSeek's Focus: Reasoning Through RL
- DeepSeek R1 aims to enhance reasoning skills in AI using reinforcement learning (RL), a departure from traditional supervised fine-tuning.
- Two versions exist: R1-0 (pure RL) and R1 (RL with pre-training), addressing language mixing issues observed in R1-0.
Aha Moments: Self-Correction in R1-0
- DeepSeek R1-0, trained solely on reinforcement learning, demonstrated "aha moments."
- It self-corrected mid-process, a novel behavior indicating improved reasoning capabilities.
Language Mixing Challenges in R1-0
- DeepSeek R1-0 exhibited language mixing issues, switching between languages like English, Chinese, and Korean.
- This compromised readability, prompting the development of R1 with improved language consistency.
