Jina AI's Finetuner is a Python library for task-oriented fine-tuning of pretrained models like BERT and CLIP to produce better embeddings for neural search. It streamlines the fine-tuning workflow and can run training jobs on Jina AI Cloud GPU infrastructure.

Use cases

• fine-tune BERT for semantic text search
• improve CLIP embeddings for text-to-image search
• train embeddings with few hundred labeled samples
• metric learning with triplet loss
• hard negative mining for similarity search
• fine-tune image similarity models

When to choose

• you need domain-specific embeddings for search or recommendation
• you have limited labeled data and want few-shot fine-tuning
• you want cloud GPU training without managing infrastructure

When to avoid

• you need fully local/offline training without Jina AI Cloud
• you need general-purpose LLM instruction fine-tuning rather than embedding tuning
• you require a very actively developed tool - releases have slowed
