# astroPT: a Large Observation Model for Astronomy

Here we have the model files for the astroPT project, the code to run inference
with these models is found here:
[https://github.com/smith42/astropt](https://github.com/smith42/astropt)

You will find the fully trained models (pretrained on 8.6 million galaxies) in
folders labelled with the model parameter count in the `astropt` directory.

Unlike the older models, these models are trained on the "clipped" galaxies in 
[this dataset](https://huggingface.co/datasets/Smith42/galaxies).

We get some promising scaling on this new dataset, see below:
