GPT-2: Too Dangerous To Release — A 2019 Retrospective
Original: GPT-2: Too Dangerous To Release (2019)
A retrospective on OpenAI's controversial 2019 decision to withhold GPT-2's full model over misuse safety concerns.
In 2019, OpenAI staged the release of GPT-2, citing fears it could enable large-scale disinformation and spam generation. The move sparked debate: was it responsible AI safety practice or a savvy PR stunt? Written in late 2022, this blog post revisits the episode now that GPT-2 looks quaint compared to GPT-3/4, asking whether the original fears were justified.
In February 2019, OpenAI publicly released its GPT-2 research results but made an extremely rare decision at the time: it refused to release the full 1.5-billion-parameter version of the model, citing "too high potential misuse risk." OpenAI stated that GPT-2's text is so fluent that it can easily generate fake news, phishing emails, and online harassment. Once the full model is leaked, malicious actors can easily deploy it on a large scale.
