As an AI language model, I don't have a specific software version number like traditional software applications. I am based on OpenAI's GPT-3 model, which is the third iteration of the Generative Pre-trained Transformer series. My responses are generated using the underlying model and its parameters, but I do not have a fixed version number. OpenAI may make updates and improvements to the model over time, but I am not aware of the specific version number I am built on.
