OpenAI has released its first open-weight language models since GPT-2, marking a significant strategic shift as the company seeks to expand enterprise adoption through more flexible deployment options and reduced operational costs.
The two new models — gpt-oss-120b and gpt-oss-20b — deliver what OpenAI describes as competitive performance while running efficiently on consumer-grade hardware. The larger model reportedly achieves near-parity with OpenAI’s o4-mini on reasoning benchmarks while running on a single 80 GB GPU, while the smaller variant matches o3-mini performance and can operate on edge devices with just 16 GB of memory.
