Hi there, we need to push that forward, I need orientation to make some decisions:

• @MadeWithStone - are you willing to continue the task
• @probicheaux - what is the status of Florence 2 model on the platform, in particular:
  • what kind of pre-trained models we support
  • where Florence 2 could run - my brief analysis indicated that only on GPU server builds - if so, the block itself is not practically useful, even potentially harmful once random users got hyped, enter Workflows and see something is broken, without proper info on how to run
  • do we have plan on making good docs about this VLM?
  • do we have plan to onboard the model on the inference platform? what about CPU builds?
