DeepSeek Flash Behaves Like a Large, Undertrained Model, Dev Observes
teortaxesTex · x · 2026-08-07
Developer teortaxesTex provided a deep analysis of the DeepSeek Flash model's behavior based on a quoted tweet.
Key Observations:
- Behavioral Contrast: The model acts like a wise teacher when offering advice, but is "dumb as a rock" when actually executing tasks.
- Training Mechanism Speculation: The author feels that Flash-0731 behaves more like a large and relatively undertrained model rather than a small, amazingly trained one.
- Parameters vs. RL Budget: It seems as if they tripled the active parameters without scaling the reinforcement learning (RL) budget by 30x, suggesting some new training regime.
