 ### Model Types
 
-Currently the two model files, `Kokoro_espeak.gguf` and `Kokoro_no_espeak.gguf`, are non-quantized representations which support espeak-ng phonemization and tts phonemization respectively.
+Currently there are two types of model each with five levels of quantization. The GGUF model files containing `_espeak` are configured to expect and use espeak for phonemization and those containing `_no_espeak` support tts native phonemization. The GGUF model files with no quantization suffix (i.e. `Kokoro_espeak.gguf` and `Kokoro_no_espeak.gguf`) use only 32bit floating point precision and the GGUF model files with Q4, Q5, Q8, and F16 suffixes support Q4_0 quantization, Q5_0 quantization, Q8_0 quantization, and 16 bit floating point precision respectively.
