Crisp on the outside, thoughtful on the inside. A keeper.
Summary
OpenAI has released open-weight models under the Apache 2.0 license, available in two sizes: 120B and 20B. The gpt-oss-120b model performs nearly as well as OpenAI's o4-mini on core reasoning benchmarks and runs efficiently on a single 80 GB GPU. The gpt-oss-20b model matches the performance of OpenAI's o3-mini on common benchmarks and is suitable for edge devices with 16 GB of memory. These models are ideal for on-device use cases and local inference.
