Original Pull Request: https://github.com/ollama/ollama/pull/11301

State: closed
Merged: No

This moves the special token list creation into the constructor, so that SpecialVocabulary() doesn't need to run sync.Once.Do() repeatedly. Doing this only once per model load avoids excessive memory allocations during chat requests when sync.Once.Do() is called with a Closure / Anonymous function.

Fixes #11299
