- IBM Granite 4.2 8B dense (8.79B params, llama-bench reports 'granite 3B Q4_K - Medium' arch label; 40 layers, GQA 32/8 heads, head_dim 128, native ctx 131072). Official ibm-granite GGUF repo rev 31239b3e4a93. Cold-start bench: pp512 1717 tok/s, tg128 53.55-55.8 tok/s (r=3). KV q4_0 vs f16: no measurable speed difference at this size. Peak VRAM 6571 MiB during bench. Max context verified live on RTX 3060 12GB full offload with q4_0 KV + FA: 104K (106496) loads and completes; 112K OOM on KV alloc; 128K OOM. Serving prefill at ~2.6K-token real prompt: 1635 tok/s, decode 47.5 tok/s (thinking model: output goes to reasoning_content first, so serving decode includes thinking tokens). Model is a native reasoning model (thinking always on in weights); benchmark used raw completions-style measurement. TTFT estimated from bench medians (prompt_ms + first-token) at 512/128 cold start.
