Further fine-tuning CLIP with contrastive losses often fails on out-of-distribution data

The author notes that fine-tuning CLIP models further with contrastive losses usually fails due to lack of data or poor data quality, especially when distribution differs significantly from training data. He argues decent coding agents can orchestrate the needed experiments on OpenCLIP, particularly the cleaned-up 4.x main branch.
