Gemma4 E4B EXL3 - Alternative to Llama.cpp on Jetson Orin
My Jetson Orin–optimized engine, little-gemma V1.0, substantially outperforms llama.cpp.

Proof1 community thread
Key points
- Even after exhausting every practical GGUF option, however, it still falls short of the ideal performance level for Gemma E4B on the Jetson Orin Nano Super 8GB.
- I forked exllamav3 and ported key code from little-gemma V1.0.
- Although the decoding rate took a hit, overall voice-chat latency is lower.
- EXL3 on the Jetson Orin Nano isn’t for everyone, but if you need the superior prefill rate, this is it.
