TL;DR
Jun Kim, creator and maintainer of the open-source oMLX inference engine, has joined Hugging Face to work on Apple’s MLX ecosystem. Hugging Face says oMLX will receive funded maintenance while remaining Apache 2.0 licensed and under Kim’s leadership; timelines and specific deliverables have not been announced.
Jun Kim, creator and maintainer of the open-source oMLX inference engine, has joined Hugging Face to work on Apple’s MLX ecosystem, as detailed in Thorsten Meyer AI’s coverage. Hugging Face says it will fund and support oMLX’s continued development while keeping the project Apache 2.0 licensed and under Kim’s leadership, giving the single-maintainer project institutional backing.
Hugging Face described the change as moving oMLX from a side project to a fully maintained and funded project. The company said that support is expected to improve stability and speed development, and to help Kim guide contributors and plan for the long term. Those are the company’s stated expectations; it has not published a delivery schedule or funding details.
The announcement identifies a technical focus: making it easier to turn a model definition in the Transformers library into a reference implementation for MLX that multiple inference engines can use. Hugging Face said its goal is to make new Transformers models easier to run on MLX. It also said oMLX may serve as a place to test ideas built on libraries such as mlx-lm and mlx-vlm, with work potentially contributed to other parts of the ecosystem where appropriate.
Hugging Face said Kim will continue to lead oMLX and that its Apache 2.0 license will remain. The company also pointed to the Hugging Face Hub as a place to discover and share MLX models, and said it wants closer collaboration with teams behind projects including mlx-lm, mlx-vlm and LM Studio. The announcement describes those collaborations as an aim, rather than listing agreed shared projects or specific contributions.
What Funded oMLX Could Change
For people running models on Apple Silicon, a funded maintainer could provide more continuity for software that helps run inference locally. That may reduce reliance on cloud services for some workloads, though the announcement makes no claims about performance, device support or which models oMLX will run next.
The move also addresses a practical risk for open-source infrastructure: a project led by one maintainer can struggle to sustain development alongside other work. Hugging Face says Kim’s role will give oMLX more stable support. Whether that translates into faster releases or broader contributions can be assessed only as changes appear in the project.
Hugging Face’s stated interest in upstreaming work could benefit developers beyond oMLX if useful improvements reach shared MLX libraries. The company has not named planned upstream changes, however, so the scope of that potential benefit remains unknown.
How oMLX Fits Into MLX
MLX is Apple’s machine-learning framework designed for Apple Silicon. Released in late 2023, it supports machine-learning work on Apple hardware. Projects such as mlx-lm and mlx-vlm build tools and model support around that framework; oMLX is an inference engine created and maintained by Kim.
Hugging Face says it has supported MLX since its release and hosts MLX models on its Hub. The company framed Kim’s appointment as part of its broader commitment to local AI. It also cited work with MLX-related projects, including mlx-lm, mlx-vlm and LM Studio, and expressed interest in stronger ties with their teams.
““We are completely invested in local AI, and MLX is a central piece of the ecosystem.””

Role Details and Delivery Dates
The announcement does not give Kim’s exact job title, team placement, start date or the financial terms and scope of oMLX’s funding. It also sets no timetable for the proposed Transformers-to-MLX workflow or for stability and development improvements.
Hugging Face expressed interest in collaboration and upstream contributions, but did not identify specific deliverables or commitments from other MLX teams. The announcement does not establish how project priorities will be set beyond saying that Kim will continue to lead oMLX.
Subsequent oMLX releases and repository updates will show whether funded maintenance leads to a steadier release pace or new stability work. Another signal will be concrete progress on making Transformers model definitions easier to use with MLX implementations across inference engines.
Developers can also watch for named joint work with mlx-lm, mlx-vlm, LM Studio or other MLX teams, and for contributions moving from oMLX into shared libraries. Hugging Face said it will continue supporting MLX models on the Hub, but did not give a schedule for any of these developments.
