A family for different jobs
IBM’s design guidance documents Plex as its corporate typeface and explains its four subfamilies. It specifically discusses Mono for code. This makes the family useful to study as a coordinated type system, rather than a single logo font.

Unlike a private corporate font, IBM Plex has an official open-source distribution linked from IBM’s typeface guidance. Visit that source for the current release and its license. You may find that the original already fits your project.
Evidence for this attribution ↓When to explore another direction
If Plex’s character does not suit your project, compare the alternatives using realistic headings, labels, and paragraphs. Our notes describe possible design directions, not fonts used by IBM. Keep one test layout consistent so that differences in width and rhythm are easier to judge.
Common questions
Where can I get the original IBM Plex?
IBM’s typeface guidance links to its official GitHub releases and describes the open-source license. Use the source link below to reach that distribution.
Is IBM Plex the striped IBM logo?
This attribution concerns corporate typography. A documented corporate font does not by itself identify the construction of a separate logo.
