Introducing gpt-oss
OpenAI Blog ● Covered by 2 sources
OpenAI released two open-weight language models called gpt-oss-120b and gpt-oss-20b under the Apache 2.0 license. The larger model contains 120 billion parameters while the smaller contains 20 billion parameters, both optimized to run on consumer hardware. Users can now deploy these models without licensing restrictions and benchmark them against similarly sized open alternatives on reasoning and tool-use tasks.
Why it matters
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.
