OpenAI’s Open-Source AI Model Leaked: 120 Billion Parameter MoE Model Imminent?
A powerful new open-source AI model from OpenAI, potentially featuring a 120 billion parameter Mixture of Experts (MoE) architecture, is rumored to launch within hours. Leaked repository snapshots, showing models with names like gpt-oss-120b and gpt-oss-20b, coupled with the deletion of these repositories and the involvement of OpenAI team members, strongly suggest this development.
What do the leaks reveal?
Developers have discovered leaked repository information—including screenshots and a configuration file— hinting at a significant shift in OpenAI’s strategy. The “gpt-oss” tag in the repository names points to a potential release of OpenAI’s GPT models as open-source software, a departure from their typical closed-source approach. This family of models, spanning various sizes, indicates a well-planned initiative.
A leaked configuration file provides a glimpse into the architecture of the rumored 120 billion parameter model, revealing it’s built using a Mixture of Experts (MoE) architecture. This innovative approach leverages 128 specialist advisors, selecting the best four to answer any given query. This allows the model to achieve impressive scale and performance while maintaining efficiency by only engaging a subset of its “experts” at any given time. Key architectural features also include a large vocabulary and Sliding Window Attention for efficient processing of long text sequences.
OpenAI’s Potential Motivation:
This potential release strategically positions OpenAI to compete directly with open-source titans like Mistral AI’s Mixtral and Meta’s Llama models. This move may be a direct response to criticism regarding its past closed-source approach and a proactive effort to foster collaboration and innovation within the AI community. It could be a significant charm offensive to regain trust and support from developers, researchers, and the wider AI community.
A Landmark Event Awaits?
The launch of a high-performance, open-source, 120 billion parameter MoE model from OpenAI would be a significant development. While information is currently based on leaked data, the signs point to an exciting and potentially transformative release in the field of artificial intelligence. An official announcement from OpenAI will be crucial for validating these claims.
