A new research paper analyzes the trade-offs between Supervised Fine-Tuning (SFT) and In-Context Learning (ICL) for personalizing Large Language Models (LLMs). The study reveals that the optimal choice between SFT and ICL depends on factors like pretraining coverage and data signal-to-noise ratio, with congestion from other users potentially altering these preferences. The research also indicates that offering both personalization methods can maximize platform profits without necessarily increasing computational load. Experiments using GPT-2 and a review of 21 AI platforms support these findings, showing a significant increase in platforms offering both SFT and ICL between 2021 and 2025. AI
