History

Historical Context

In February 2019 OpenAI announced GPT-2, a 1.5-billion-parameter model whose staged release sparked debate over misuse. Researchers such as the Allen Institute responded with detection tools, and GPT-2 later achieved state-of-the-art results on seven of eight zero-shot benchmarks. The episode created ongoing oversight concerns that reappear as OpenAI’s reported GPT-6 Astra and a recent SpaceXAI outage revive calls for regulation.
