Quantization
From quantization_config.json:
- Method: EXL3
- ExLlamaV3:
0.0.29
- Target: 4.00 bpw, head bits 6
- Codebook: mcg
- Output scales: always
- Calibration: 250 rows × 2048 cols

Serving notes (24 GB)
Worked here in TabbyAPI:
cache_mode: Q8
cache_size: 8192
vision: true (or omit; vision tensors are in the shards either way)
chunk_size: 2048
- Point
prompt_template at gemma4.jinja if the tokenizer has no chat template
Rough VRAM with vision + Q8 8K KV: ~18.6 GB.
