OpenAI leak suggests imminent open-source GPT model release
OpenAI is reportedly on the verge of releasing a significant open-source AI model, with some indications suggesting an imminent launch.
This speculation stems from a series of digital traces, primarily screenshots of now-deleted model repositories on platforms like GitHub. These repositories, bearing names such as yofo-deepcurrent/gpt-oss-120b and yofo-wildflower/gpt-oss-20b, were reportedly linked to OpenAI team accounts. The gpt-oss designation is widely interpreted as ‘GPT Open Source Software,’ signaling a potential shift back towards the company’s more open origins after years of focusing on proprietary models. The presence of multiple codenames and parameter sizes suggests a planned family of models.
Further details, reportedly from a leaked configuration file, shed light on the suspected 120-billion-parameter version. This model appears to be built on a Mixture of Experts (MoE) architecture. In this design, instead of a single large model handling all tasks, the system intelligently selects a few specialized ‘experts’ – in this case, four out of 128 – for each query. This approach combines the vast knowledge capacity of a large model with the operational efficiency and speed typically associated with smaller systems, as only a fraction of its components are active at any given time. Beyond its architecture, the model is also said to feature a large vocabulary, enhancing its efficiency across various languages, and employ Sliding Window Attention, which allows it to process extensive text sequences effectively.
Should these specifications prove accurate, OpenAI’s potential open-source release would directly compete with established models in the open-source AI landscape, notably Mistral AI’s Mixtral and Meta’s Llama family.
The timing of such a release invites speculation regarding OpenAI’s strategic motivations. For years, the company has faced criticism for deviating from its foundational commitment to openness, particularly as it increasingly commercialized its advanced models. A powerful open-source release could serve as a significant gesture to reconnect with the developer and research communities who felt overlooked. Furthermore, it represents a shrewd competitive maneuver. Companies like Meta and Mistral have demonstrated how a vibrant open-source ecosystem can accelerate innovation and foster widespread adoption. By introducing a high-performance open-source model, OpenAI would not only enter this competitive arena but also seek to influence its direction.
While these details remain unconfirmed by OpenAI, the evidence from leaked code and configuration files lends considerable weight to the speculation. The potential launch of a high-performance, 120-billion-parameter open-source MoE model from a company as prominent as OpenAI would undoubtedly mark a significant development in the artificial intelligence sector, and its arrival appears to be drawing near.
