Before revision:  Meanwhile, more powerful generative models have been released, from RNN-based methods to the GPT-2 language model. State-of-the-art language models, transformer-based in particular, can generate synthetic text in response to the model being primed with arbitrary input. Thus, Therefore, it is crucial to develop tools that help to detect media authenticity.
After revision:  Meanwhile, more powerful generative models have been developed. Adversaries can exploit these tremendous generative capabilities to enhance social bots that will have the ability to write plausible deepfake messages, hoping to contaminate public debate. To prevent this, it is crucial to develop tools that help to detect media authenticity.
