Summary
This pins down a concrete record about a specific AI model: GPT-J, built by EleutherAI, is a 6-billion-parameter variant of the GPT architecture that was made publicly available in July 2021. It matters because it locks in the model's size, creator, openness, and release timing, giving the system a solid reference point for reasoning about its capabilities, availability, and how it compares to other models in the landscape.
