gemma-embedding.cpp)
- imlpemented → implemented (llama-adapter.cpp)
- interere → interfere (llama-graph.cpp)
- overridde → overridden (chat.cpp)
- stastistics → statistics (ngram-map.h)
- layed → laid (llama-kv-cache.h)
- worster → worst (llama-context.cpp)
- sequantial → sequential (llama-batch.h)
