OpenAI CEO Sam Altman said on Monday that OpenAI plans to release the first open heavyweight language model with reasoning capabilities since GPT-2 in the coming months, and the company will discuss with developers how to make it work. An open weight language model is a type that allows model weighting to be adjusted or fine-tuned based on new input data or tasks. "We also need to make some decisions, so we're hosting a developer event to gather feedback and try out early prototypes later," Altman said.
