Tellusim Core SDK Opens Up For Use By OSI-Approved Open-Source Projects

Written by Michael Larabel in Linux Gaming on 20 October 2025 at 08:27 PM EDT. 10 Comments
Over the weekend we wrote about the visually-impressive Tellusim Core SDK being posted to GitHub as a C++ SDK for high-end graphics and compute. The downside was that the Tellusim Core SKD was rather restrictive in only being free for education, free for companies with less than $200k USD in annual revenue, and evaluation purposes. Or you needed to obtain a negotiated license for the software. As a pleasant surprise, OSI-approved open-source projects not backed by for-profit organizations can now openly use this superb graphics SDK.

In responding to feedback raised on the prior Phoronix article, Tellusim founder Alexander Zapryagaev added an exception for such open-source projects that are community-focused / not backed by a for-profit organization.

The Tellusim Core SDK has now added this license acknowledgement:
"Tellusim Core SDK is free for open source non-commercial projects distributed under OSI-approved licenses (such as MIT, BSD, GPL, LGPL, or Apache 2.0), provided that such projects are not affiliated with or sponsored by for-profit organizations."

Thus now opening it up to more uses and making this project certainly much more interesting to community open-source developers / hobbyists. Great job Tellusim Technologies!
