# Model Card for CONCHv_1_5
 
## What is CONCHv_1_5?

CONCHv_1_5 is based on the CONCH model, a vision-language model pretrained on 1.17 image/captions in histopathology. CONCHv_1_5 is based on a Vision Transformer Large (ViT-L) model restored from the UNI checkpoint, and fine-tuned in a similar fashion as CONCH.

## Requesting Access

As mentioned in the gated prompt, you must agree to the outlined terms of use, _**with the primary email for your HuggingFace account matching your institutional email**_. If your primary email is a personal email (@gmail/@hotmail/@qq) **your request will be denied**. To fix this, you can: (1) add your official institutional email to your HF account, and confirm your email address to verify, and (2) set your institutional email as your primary email in your HF account. Other reasons for your request access being denied include other mistakes in the form submitted, for example: full name includes abbreviations, affiliation is not spelled out, the described research use is not sufficient, or email domain address not recognized.
