据数字线索显示，OpenAI可能在几小时内发布一款强大的新型开源AI模型。泄露的截图揭示了包含“gpt-oss”字样的模型存储库，暗示其为GPT开源软件。此次发布将标志着该公司回归早期开放的理念，并可能推出一系列不同版本和规模的模型。其中一款1200亿参数的模型据称采用了混合专家（MoE）架构，拥有128个专业顾问，能智能选择最合适的专家处理查询，兼具大型模型的知识广度和小型系统的速度。该模型还具备庞大的词汇量和滑动窗口注意力机制，以高效处理长文本。此举被视为OpenAI对开发者社区的“魅力攻势”，并旨在通过强大的开源模型引领AI领域的竞争格局。

💡 OpenAI或将发布名为“gpt-oss”的开源AI模型，这标志着该公司向早期开放理念的回归，并可能推出一系列多版本、多规模的模型。

🧠 泄露的1200亿参数模型可能采用混合专家（MoE）架构，即由128个专业“专家”组成，系统能智能调用最合适的专家处理任务，从而实现高效且强大的性能。

🗣️ 该模型预计拥有庞大的词汇量和滑动窗口注意力机制，使其在处理多语言和长文本方面表现出色，兼具强大性能与实际运行的便利性。

🚀 此举被解读为OpenAI旨在重新吸引开发者和研究者群体，同时也是一项竞争策略，旨在通过推出强大的开源模型来重塑AI领域的竞争格局。

A leak suggests that OpenAI is about to launch a powerful new open-source AI model, potentially within hours.

The evidence comes from a trail of digital breadcrumbs, eagerly pored over by developers. At the centre of it all are screenshots showing a series of model repositories with names like yofo-deepcurrent/gpt-oss-120b and yofo-wildflower/gpt-oss-20b. The repos have since been deleted, but the accounts feature OpenAI team members.

That gpt-oss tag is the real smoking gun, seemingly a clear signpost for ‘GPT Open Source Software’. For a company that has increasingly guarded its top-tier models, this would be somewhat of a return to its roots. The fact that we are seeing multiple versions, with different codenames and sizes, suggests a well-planned family of models are about to make their debut.

Thanks to a leaked configuration file, we can even peek under the bonnet of the suspected 120 billion parameter version.

The model appears to be built on a Mixture of Experts, or MoE, architecture. Think of it less like a single, monolithic brain trying to know everything, and more like a board of 128 specialist advisors. When a query comes in, the system intelligently selects the four best experts for the job. This gives the model the vast knowledge of its huge parameter count, but the speed and agility of a much smaller system, as only a fraction of it is working at any one time.

This design puts OpenAI’s open-source AI model squarely in competition with the darlings of the scene, like Mistral AI’s Mixtral and Meta’s Llama family.

And the specs don’t stop there. OpenAI’s open-source AI model appears to boast a huge vocabulary, which should make it more efficient with a wider range of languages, and uses Sliding Window Attention to handle long streams of text without breaking a sweat. In practice, this all points to a model that is both powerful and practical to run.

So, why would OpenAI make such a move now? For years, the company has faced gentle jabs and outright criticism for straying from its more open beginnings. Launching a powerful gpt-oss would be a massive charm offensive aimed directly at the developers and researchers who felt left behind.

Of course, it’s also a shrewd competitive play. Meta and Mistral have shown how a thriving open-source ecosystem can drive innovation. By dropping a powerful open-source AI model like this appears to be into the mix, OpenAI isn’t just joining the race; it’s attempting to redefine the track.

Until we get the official word from OpenAI, this is all still, technically, rumour. But it’s a rumour with substance, backed by code and configuration files.

The launch of a high-performance, 120-billion-parameter open-source MoE model from the most famous name in AI would be nothing short of a landmark event, and it appears to be imminent.
