OpenAI launched two open-weight models named gpt-oss for local use. The lighter model, gpt-oss-20b, has 21 billion parameters and needs about 16GB of memory. The heavier gpt-oss-120b requires 80GB of memory to run successfully. Running gpt-oss-20b is feasible for many users with appropriate hardware, needing a GPU with 16GB VRAM or 24GB system memory. To use gpt-oss-20b on Windows, users must download the Ollama app, which simplifies the process of downloading and executing the model with user prompts.
OpenAI recently launched two open-weight models named gpt-oss, allowing users to download and run them locally, with gpt-oss-20b being the lighter model at 21 billion parameters.
gpt-oss-20b requires around 16GB of free memory to operate, while the heavier gpt-oss-120b needs 80GB, highlighting the varying hardware needs for running these models.
For users without high-end AI servers, gpt-oss-20b is more accessible, requiring only a GPU with at least 16GB of VRAM or 24GB system memory.
To utilize gpt-oss-20b on Windows, download the Ollama app, which facilitates an easy setup and allows interaction with the language model via prompts.
