About

GPT-OSS-20B is an open-weight model from OpenAI's open-source initiative, designed for deployments requiring local or self-hosted inference at a practical scale. It reflects OpenAI's entry into the openly licensed model space — a significant strategic shift for a company that had historically kept its most capable models proprietary, targeting organizations that need capable AI within their own infrastructure without API dependency.
