Introducing gpt-oss. We’re releasing gpt-oss-120b and gpt-oss-20b—two state-of-the-art open-weight language models that deliver strong real-world performance at low cost. Available under the flexible Apache 2.0 license, these models outperform similarly sized open models on reasoning tasks, demonstrate strong tool use capabilities, and are optimized for efficient deployment on consumer hardware. This update is relevant for small-office operators tracking changes in their tools.
Operator takeaway: For operators: review whether 'Introducing gpt-oss' affects your current setup before relying on it in production.
