Thought experiments and models are many times considered as being distinct scientific activities that share different features. Some scholars have attempted to discriminate thought experiments from other hypothetical constructions and, speaking of models, other researchers have likewise proposed that models belong to a distinct ontological class. All of them try to answer the question “What is a thought experiment/model?”. I take issue with this strategy; I propose that the definitions on offer for thought experiments do not manage to conclusively discriminate them from other hypothetical scenarios and that the philosophical theories that try to tie models to ontological categories face similar hurdles. The attempts to discriminate between them based on the assumed different role they have in science also lead to highly questionable conclusions. My takeaway is that thought experiments and models can be considered as having no substantially different features.
