OpenAI has announced GPT-oss, its first family of large language models with open weights in over five years. This release allows anyone to access the operational details of the model post-training. Sam Altman claims this to be the most usable open model globally. Analysts note that OpenAI’s release may narrow the gap with China, though China still leads in the quantity and market availability of competitive models. The launch may also expedite open-source releases from Chinese firms to maintain market relevance.
We believe this is the best and most usable open model in the world, Altman wrote on X on Aug 6.
OpenAI's new models narrowed the gap with China thanks to their competitive performance benchmarks and sizes against their Chinese counterparts.
China still maintains a slight lead, with a broader, higher number of competitive open-source models available in the market compared with the US.
The launch of OpenAI's open-weight models may prompt Chinese firms to accelerate their own open-source releases to stay competitive.
