[5] IBM's focus is to open up technology surrounding their Power Architecture offerings, such as processor specifications, firmware, and software with a liberal license, and will be using a collaborative development model with their partners.

[8] The governing body around the Power ISA instruction set is now the OpenPOWER Foundation: IBM allows its patents to be royalty-free for Compliant implementations.

[10] IBM is using the word "open" to describe this project in three ways:[7] OpenPower Foundation also releases Documentation on the Power Architecture.

The generic memory controllers are designed to evolve with future technologies, and the new CAPI (Coherent Accelerator Processor Interface) expansion bus is built to integrate easily with external coprocessors like GPUs, ASICs and FPGAs.

[13] In August 2019, IBM released the tiny Microwatt processor core implementing the Power ISA v.3.0 and to be used as a reference design for OpenPOWER.

[21][22] Collabora Online is an enterprise-ready edition of LibreOffice with web-based office suite real-time collaboration, support of the OpenPOWER ppc64le architecture was announced in October 2022.

[23] It comes with Ubuntu 20.04 packages and Docker images, and is delivered as a part of Nextcloud Enterprise which specialises in sharing files, writing emails, conducting chats and video conferences.

As of April 2014, Canonical, Chuanghe Mobile, Emulex, Hitachi, Inspur, Jülich Research Centre, Oregon State University, Teamsun, Unisource Technology Inc, and ZTE are listed as members at various levels.
