Hustler Words – OpenAI’s highly anticipated open model, slated for release next week, has been indefinitely delayed, CEO Sam Altman announced Friday via X. This marks the second postponement this summer, as the company prioritizes further safety testing. Altman explained, "We need time to run additional safety tests and review high-risk areas. We are not yet sure how long it will take us. While we trust the community will build great things with this model, once weights are out, they can’t be pulled back. This is new for us and we want to get it right."
The delay casts a shadow over OpenAI’s ambitions to maintain its position as a leading AI lab, particularly with competitors like xAI, Google DeepMind, and Anthropic making significant investments in their own AI endeavors. The open model’s release, alongside the expected launch of GPT-5, was anticipated as a major demonstration of OpenAI’s capabilities. Unlike GPT-5, the open model will be freely available for developers to download and run locally.
This setback comes just as the open-source AI landscape heats up. Chinese startup Moonshot AI recently unveiled Kimi K2, a trillion-parameter model that outperforms OpenAI’s GPT-4.1 on certain benchmarks. OpenAI’s open model was previously reported by hustlerwords.com to possess reasoning capabilities comparable to its o-series models, aiming for best-in-class performance among open models.

In June, Altman hinted at "unexpected and quite amazing" advancements achieved with the model, without providing specifics. Aidan Clark, OpenAI’s VP of research leading the open model team, echoed the sentiment on X, stating, "Capability-wise, we think the model is phenomenal – but our bar for an open-source model is high and we think we need some more time to make sure we’re releasing a model we’re proud of along every axis."
Previous hustlerwords.com reporting suggested plans to integrate the open model with OpenAI’s cloud-hosted models for complex queries. However, the inclusion of this feature in the final release remains uncertain. The indefinite delay leaves developers and the wider AI community in a state of suspense, eagerly awaiting the eventual arrival of OpenAI’s ambitious open-source offering.
