K2-Horizon-MoVA-36B-A4B — ROCmFP4 for AMD Strix Halo (gfx1151)

Four ROCmFP4/ROCmFPX tiers of IFM/K2-Horizon-MoVA-36B-A4B, quantised from the official BF16 GGUF and measured on a Ryzen AI Max+ 395 (Radeon 8060S, gfx1151, 128 GB unified, ROCm 7.2.4). This is the dual-expert k2_horizon MoVA architecture — 36B total parameters, ~4B active — with two independent expert systems: a 64-way MoVA value-expert bank (top-4) alongside a 100-way MoE feed-forward (top-8), 48 layers, hidden 2560, and it is a reasoning model.

Every number on this card was measured on these exact files. Nothing is estimated. As an A4B MoE, it decodes far faster than a dense 32B on the same hardware.

Which file should I use?

file	ftype	size	decode (HIP)	prefill (HIP)	use it for
`K2-Horizon-MoVA-36B-A4B-Q4_0_ROCMFP4_FAST.gguf`	103	18.57 GiB	41.0 t/s	1238 t/s	default — fastest on both axes
`K2-Horizon-MoVA-36B-A4B-Q4_0_ROCMFP4_STRIX_LEAN.gguf`	106	18.67 GiB	41.0 t/s	1227 t/s	same speed, Q5_K embeddings
`K2-Horizon-MoVA-36B-A4B-Q4_0_ROCMFP4_COHERENT.gguf`	102	19.81 GiB	39.5 t/s	1114 t/s	most bits in the 4-bit family
`K2-Horizon-MoVA-36B-A4B-Q8_0_ROCMFPX_AGENT.gguf`	115	36.45 GiB	28.9 t/s	1183 t/s	8-bit, agent/tool-call routing

Start with FAST — fastest on both axes here, all four answer correctly. Take AGENT only if you specifically want 8-bit weights.

Quick start — the backend is one flag

# HIP / ROCm — best prefill (long prompts, RAG, agentic)
llama-server -m K2-Horizon-MoVA-36B-A4B-Q4_0_ROCMFP4_FAST.gguf \
  -dev ROCm0 -fa on -ngl 999 --no-mmap -fit off -np 1 \
  -b 2048 -ub 1024 -t 16 --poll 100 -c 8192 --jinja

# Vulkan — SAME FILE. Only -dev changes.
llama-server -m K2-Horizon-MoVA-36B-A4B-Q4_0_ROCMFP4_FAST.gguf -dev Vulkan0 ...

⛔ You need a build with BOTH `k2_horizon` and the ROCmFP4 types

These declare general.architecture = k2-horizon and use the ROCmFP4/ROCmFPX tensor types (ggml 100-119). No single public build has both yet:

k2_horizon arch (incl. the MoVA dual-expert graph) — MBZUAI-IFM llama.cpp fork; upstream PR in progress.
ROCmFP4/ROCmFPX types — ROCmFPX.

This repo ships k2-horizon-on-rocmfpx.patch — the arch applied onto a ROCmFPX base, the exact tree these files were built and verified against:

git clone https://github.com/ROCmFPX/ROCmFPX.git && cd ROCmFPX
curl -fLO https://huggingface.co/kingjones777/K2-Horizon-MoVA-36B-A4B-ROCmFP4-GGUF/resolve/main/k2-horizon-on-rocmfpx.patch
git apply k2-horizon-on-rocmfpx.patch
cmake -B build -DGGML_HIP=ON -DGGML_VULKAN=ON -DAMDGPU_TARGETS=gfx1151 -DGGML_NATIVE=ON -DCMAKE_BUILD_TYPE=Release
cmake --build build -j$(nproc)

⛔ Serving note — this is a reasoner

MoVA-36B emits chain-of-thought into reasoning_content before answering. A short budget returns HTTP 200 with empty content and the tokens in reasoning — the model thinking, not a broken file. Give it room: ~500 tokens for short answers and tool calls, more for long-form. Verified: at 40 tokens content was empty; at 500 it answered correctly.

Head handling

Quantised at each tier's native routing with no forced --output-tensor-type override; the tiers are posted as-built.
