 ## [Unreleased]
 
+### Fixed
+
+- Fixed compiled release binaries bundling `fastembed` and baking the build-machine `@anush008/tokenizers` path; native runtime dependencies now stay external for every compiled build path so Mnemopi resolves its on-demand install instead. ([#5195](https://github.com/can1357/oh-my-pi/issues/5195))
+
 ## [16.4.5] - 2026-07-11
