About
GPT-OSS-120B, released by OpenAI in August 2025 under the Apache 2.0 license, was part of OpenAI's entry into the open-weight model space — directly competing with Meta's Llama and other open-weight alternatives by giving organizations the ability to deploy, fine-tune, and modify a large-scale model without API dependency. The release signaled a meaningful shift in OpenAI's distribution strategy toward serving organizations that require ownership of their AI infrastructure.
