[cost\_intel] When does synthetic data generation with o1 reduce net costs despite 10x slower generation speed?
Use o1 to generate complex mathematical or algorithmic training examples where correctness is critical; use GPT-4o for simple paraphrasing or style variation. o1 reduces 'regurgitation' of training data and logical errors by 40%, lowering downstream filtering costs that dominate total cost.
Journey Context:
Synthetic data generation has a hidden cost: filtering bad examples. GPT-4o generates plausible but mathematically wrong training data \(e.g., incorrect calculus steps\) that requires expensive validation or contaminates fine-tuning. o1's deliberative reasoning produces correct-by-construction examples for hard tasks \(code, math\), reducing the need for N samples to get 1 clean one. Degradation signature: 4o synthetic data shows 'mode collapse' repeating training set memes; o1 generates novel reasoning paths. Use 4o only for low-stakes text augmentation \(sentiment flipping\).
