You can incorporate reinforcement learning into generative AI workflow using one of the technique called PPO(proximal policy optimization) used for fine-tuning a text generation model with custom rewards.
Here is the code for your reference:
We design a simple reward function (refer in the code) to stimulate longer generated text. We wrap up the model using PPO to adjust model generation based on rewards.
This is how we incorporate reinforcement learning in Generative AI workflow.
