You can run Galactica (the "base" model) for free on Colab (https://colab.research.google.com/). It takes about 4 minutes to start up. Just specify a "GPU" runtime on colab, and follow the simple instructions from their github (https://github.com/paperswithcode/galai):

!pip install galai

import galai as gal

model = gal.load_model("base")

model.generate("Scaled dot product attention:\n\n\\[")
