Capabilities: Could generate coherent paragraphs, answer questions, translate, and summarize without task-specific training.
The “Too Dangerous to Release” Controversy
Section titled “The “Too Dangerous to Release” Controversy”February 2019: OpenAI announced GPT-2 was “too dangerous to release” in full form.
| Timeline | Action |
|---|---|
| February 2019 | Initial announcement; only 124M parameter version released |
| May 2019 | 355M parameter version released |
| August 2019 | 774M parameter version released |
| November 2019 | Full 1.5B parameter version released |
| Within months | Grad students reproduced model for ≈$50K in cloud credits |
Reasoning: Potential for misuse (fake news, spam, impersonation). VP of Engineering David Luan: “Someone who has malicious intent would be able to generate high quality fake news.”
Community Reactions:
| Position | Argument |
|---|---|
| Supporters | Responsible disclosure is important; “new bar for ethics” |
| Critics | Overhyped danger; “opposite of open”; precedent for secrecy; deprived academics of research access |
| Pragmatists | Model would be reproduced anyway; spotlight on ethics valuable |
Outcome: Full model released November 2019. OpenAI stated: “We have seen no strong evidence of misuse so far.”

- Predicting actual harms is difficult
- Disclosure norms matter and are contested
- Tension between openness and safety is fundamental
- Model capabilities can be independently reproduced
