# 🔬 MicroLens — Microscopy AI Demo
Live demo of **MicroLens**: a fine-tuned **Gemma 4 E2B** vision-language model that identifies microscopic subjects across **2 categories** (diatoms and fungal spores) and **95 genera**.
Built by **Serghei Brinza** (Vienna, Austria) for the **Kaggle Gemma 4 Good Hackathon** (May 2026).
---
## 🚀 How to use
1. Upload a microscopy image (or pick one from the examples gallery).
2. Optionally add a question, for example: "What is shown here?", "Describe the morphology", "What category does this belong to?"
3. Click **AI Analyze**.
You get three side-by-side answers:
- **UNTRAINED BASELINE** — stock Gemma 4 E2B with no microscopy training.
- **MICROLENS · BRIEF** — same base + `Laborator/microlens-final` LoRA, prompted for a single-sentence genus answer.
- **MICROLENS · RICH** — same base + same LoRA, prompted for the full schema (genus + morphology + habitat + identification cues).

## ⚠️ Disclaimer
MicroLens is a **research and educational tool**. It is **not a medical device** and must not be used for clinical diagnosis, food-safety decisions, forensic identification, or any purpose where an incorrect answer could harm a person.
- Predictions are probabilistic and may be wrong, especially on out-of-distribution samples.
- Always verify critical findings with a qualified microscopist or laboratory.
For any vertical that requires regulatory clearance (medicine, veterinary, forensics, food safety), see the [4-stage gated rollout](https://github.com/SergheiBrinza/microlens/blob/main/ROADMAP.md) in the project roadmap.
