Pulling off a significant move in the persistently evolving artificial intelligence (AI) landscape, OpenAI has rolled out two open-weight AI reasoning models.
The new open-weight AI models entail the same suite of capabilities as OpeAI's o-series. Both models have been made freely available for download from the online developer platform Hugging Face.
In a description on its official blog post, OpenAI endorsed its latest AI models as “state of the art,” given their outpacing performance on several benchmarks for comparing open models.
The models are available in two sizes: a larger, more capable gpt-oss-120b model that can run on a single Nvidia GPU, and a lighter gpt-oss-20b model that can operate on a consumer laptop with 16GB of memory.
This launch marks OpenAI’s first ‘open’ language model since GPT-2, released over five years ago.
In a briefing, OpenAI stated that its open models will be able to send complex queries to AI models in the cloud.
This means that if the open model cannot perform a specific task, such as image processing, developers can connect it to one of the company’s more powerful closed models.
While OpenAI has open-sourced AI models in its early days, it has primarily favoured a proprietary, closed-source development approach, which has helped the company build a substantial business selling access to its AI models via an API.
This comes in contradiction with OpenAI CEO Sam Altman asserting his belief in January that OpenAI has been “on the wrong side of history” regarding open sourcing its technologies.
