  Hugging Face has been acquired by NVIDIA

  It is quite exciting to be a part of this journey! NVIDIA has been an active supporter of the llama.cpp project. For more than a year now, their engineers have actively contributed to the codebase, collaborated with the community and provisioned hardware for development and testing purposes. The local AI ecosystem has largely benefited from our joint efforts.

  Going forward, llama.cpp/ggml will stick to its founding principles. One of the most important  qualities of the project is to be hardware-agnostic. Therefore the development and support of all backends will continue to be done as usual - driven and shaped by the community. Open to everyone who is willing to participate. The existence of such an independent software platform is crucial for the rapid adoption of AI locally and for bringing it closer to the user.

  Now, with such a significant partner as NVIDIA supporting us, in addition to the wider Hugging Face team, I believe that our long-term goals will be easier to achieve. We will remain focused on building one of the most exciting projects based on the most exciting technology of our lifetime and making it truly available to everyone in the most accessible and efficient way possible.

"On Monday 24th August at 8PM EST, we received at letter from X Corp. asking to cease and desist the service XCancel.

The service XCancel is stopped until further notice.

We are seeking legal advice and won't share more details for now.

Thank you for the trust you have put in these two years of XCancel."

The answer to this question is, also, "X threw a fit". They sent Cease & Desists to nitter and xcancel.

They got a C&D.
