OpenAI Releases GPT-OSS 120B and 20B Under Apache 2.0 License

Released under Apache 2.0, the text-only GPT-OSS models run on hardware from laptops to single GPUs, having passed rigorous safety evaluations to meet growing demands for transparent AI.

Overview

  • OpenAI published gpt-oss-120b (117 billion parameters) and gpt-oss-20b (21 billion parameters) weights on platforms like Hugging Face under an Apache 2.0 license, permitting free commercial use, modification and redistribution.
  • The 117 billion-parameter gpt-oss-120b runs on a single Nvidia GPU; the 21 billion-parameter gpt-oss-20b requires just 16 GB of memory, enabling deployment on consumer laptops.
  • Benchmark tests show gpt-oss-120b performing on par with OpenAI’s o4-mini and both models outpacing DeepSeek’s R1 on Codeforces and academic assessments.
  • OpenAI’s safety regime—including adversarial fine-tuning, third-party reviews and high-risk filtering—found no evidence that the open models exceed internal danger thresholds for cyber or biological misuse.
  • The move responds to intensifying competition from Chinese AI labs and U.S. policy calls for open AI, marking a strategic pivot from OpenAI’s closed-source API business model.
