GPT-2: 1.5B release
OpenAI Blog
OpenAI released the 1.5B parameter version of GPT-2, completing its staged rollout of the model along with detection tools and weights. The model contains 1.5 billion parameters, making it the largest in GPT-2's release series. The staged release serves as a test case for how future powerful AI models might be responsibly published.
Why it matters
As the final model release of GPT-2’s staged release, we’re releasing the largest version (1.5B parameters) of GPT-2 along with code and model weights to facilitate detection of outputs of GPT-2 models. While there have been larger language models released since August, we’ve continued with our original staged release plan in order to provide the community with a test case of a full staged release process. We hope that this test case will be useful to developers of future powerful models, and we’re actively continuing the conversation with the AI community on responsible publication.
