The THEaiTRobot 2.0 tool allows the user to interactively generate scripts for individual theatre play scenes.

The previous version of the tool (http://hdl.handle.net/11234/1-3507) was based on GPT-2 XL generative language model, using the model without any fine-tuning, as we found that with a prompt formatted as a part of a theatre play script, the model usually generates continuation that retains the format.

The current version also uses vanilla GPT-2 by default, but can also instead use a GPT-2 medium model fine-tuned on theatre play scripts (as well as film and TV series scripts). Apart from the basic "flat" generation using a theatrical starting prompt and the script model, the tool also features a second, hierarchical variant, where in the first step, a play synopsis is generated from its title using a synopsis model (GPT-2 medium fine-tuned on synopses of theatre plays, as well as film, TV series and book synopses). The synopsis is then used as input for the second stage, which uses the script model.

The choice of models to use is done by setting the MODEL variable in start_server.sh and start_syn_server.sh

THEaiTRobot 2.0 was used to generate the second THEaiTRE play, "Permeation/Prostoupení".
