O penAI has released two new open-weight language models designed to run locally on laptops and deliver performance comparable to its smaller proprietary reasoning models. The launch marks the company’s first open-weight release since GPT-2 in 2019.

Amazon is offering OpenAI’s new open-weight AI models on Bedrock and SageMaker, bypassing Microsoft’s Azure exclusivity via the Apache 2.0 license.

The gpt-oss-120b and gpt-oss-20b models can run respectively on a single NVIDIA GPU or a standard 16 GB‑RAM laptop, matching performance levels of OpenAI’s proprietary “o-series” reasoning models
