Ehsan's Insight
Continuous pretraining — updating a foundation model with new data — keeps models current without retraining from scratch. A model's knowledge cutoff means it does not know about recent events, products, or research. Continuous pretraining on recent data bridges this gap at 1-5% of the cost of full retraining. Bloomberg's BloombergGPT and medical models like Med-PaLM 2 use continuous pretraining to maintain domain currency. For companies in fast-moving domains (AI, cybersecurity, finance), continuous pretraining on proprietary data every quarter maintains model relevance and creates a competitive advantage that general-purpose models cannot match.
