Can I run gemma 4 E4B it on Apple M4?
Runs
Runs fully in unified memory on your Apple M4 at UD-Q8_K_XL, 8K context, about 7.0–9.6 tok/s. Weights 8.11 GB plus 0.14 GB of KV cache — 8.64 GB of 11.0 GB usable. Up to 128K context still fits.

Assumptions
- Estimate, not a benchmark. Decode speed uses a memory-bandwidth model at 55–75% of peak.
- KV cache is FP16. Engine overhead assumes llama.cpp (0.3 GB + 1% of the weights). Ollama is closer to 0.9 GB + 3%, LM Studio closer to 1 GB + 3%.
- UD-Q8_K_XL size is the real GGUF file size from Hugging Face.
- Unified memory uses 75% for the GPU by default, and always leaves about 5 GB for the OS.
- Speed is quoted at 8K context, not at the maximum context that still fits.
