Fine-Tune a Vision-Language Model for Image Captioning
Overview
What this challenge is about.
Fine-tune a vision-language model on accessibility-curated images, evaluate with metrics and a user study, then write a go/no-go memo. Earn a verifiable certificate.
The scenario
The Tel Aviv consumer AI startup (around 18 staff, post-seed) ships an iOS-first accessibility app with around 40,000 active users and treats caption usefulness as its core differentiation.
The Brief
What you'll do, and what you'll demonstrate.
Fine-tune a vision-language model so its captions are actually useful for low-vision users, validated by a 30-user study.
Earning criteria — what you'll demonstrate
- Fine-tune a vision-language model with parameter-efficient methods
- Design a user study that measures real downstream usefulness
- Balance automated metrics with human judgment
- Make a ship/no-ship call on a model fine-tune
