Fine-tuning ColBERT for Medical Retrieval Beats General-Purpose Models
tomaarsen · x · 2026-08-26
A new blog post details training and fine-tuning multi-vector embedding models with Sentence Transformers. As a practical example, the author fine-tuned a ColBERT-style model for medical retrieval on a single RTX 3090 over 14.5 hours. The resulting model outperformed every general-purpose retriever tested, providing a full technical walkthrough and performance benchmarks.
