The contentment of employees is a very import aspect in working environment. Mandatory shifts, which we want to be in accordance with staff's wishes, also contribute to that. Because the current selection and assignment system in particular healthcare facility does not reach expectations, we decided to develop a system, which will provide improvements in that department. Instead of writing our own algorithm, we have tried to use the capabilities of artificial intelligence in solving the problem of scheduling. We monitored closely the products of company OpenAI, specifically models GPT-3.5-turbo, GPT-4.1 and GPT-5 and chatbot ChatGPT.We tested the models with the same input data and evaluated them based on their output, where we checked the evenness of the workload and the consideration of doctors' preferences and rest days.The chatbot had a different assignment, because it had to prepare the code, which then generates the schedule.We assessed the suitability of the code with the same input as the models.We found out that the model GPT-5 performs best in generating the schedule.The final products is a web application, that allows each staff member to select their shift preferences by day of the month and attempts to meet all requirements for created monthly schedule.
