[https://github.com/TRI-ML/prismatic-vlms Prismatic VLM ] is the project upon which OpenVLA is based. The generate .py REPL script is available in the OpenVLA repo as well but is essentially using Prismaticmodels. Note that the Prismatic models generate natural language whereas OpenVLA models were trained to generate robot actions. (see this https://github.com/openvla/openvla/issues/5).

Here are some suggestions to run the generate.py REPL Script from the repo (you can find this in the '''scripts''' folder) if you would like to get started.
