Ornith-1.0-35B-NVFP4-noMTP-BF16-GGUF

GGUF conversion of sakamakismile/Ornith-1.0-35B-NVFP4, preserving the compressed-tensors NVFP4 weights, with a BF16 vision projector (mmproj) and BF16 (lossless) embedding & output layers. Text-only checkpoint (no MTP head). Benchmarked on an RTX 5090 (Blackwell) with llama-benchy.

Highlights

NVFP4 preserved — 430 NVFP4 tensors (MoE experts, attention, linear-attention/SSM) kept in their native 4-bit format, not re-quantized.
Lossless embeddings & output — token_embd and lm_head are kept at BF16 (no Q4_K/Q6_K), so vocabulary and output-projection precision is unchanged from the source.
Vision / mmproj — a separate BF16 vision projector enables image-text-to-text.
No MTP — the source checkpoint ships no multi-token-prediction head, so this is a clean autoregressive (AR) model (block_count = 40).
Blackwell native FP4 — prefill/decoding use native FP4 tensor-core kernels on RTX 50-series (sm_120).

Files

File	Size	Description
`Ornith-1.0-35B-NVFP4-noMTP-BF16.gguf`	19.60 GiB	Main GGUF — NVFP4 body preserved, BF16 `token_embd`/`lm_head`
`mmproj-Ornith-1.0-35B-BF16.gguf`	861 MiB	Vision projector (mmproj) for image input

Usage (llama.cpp)

# Text-only
llama-server -m Ornith-1.0-35B-NVFP4-noMTP-BF16.gguf --host 0.0.0.0 --port 8080 --jinja

# With vision (image-text-to-text)
llama-server -m Ornith-1.0-35B-NVFP4-noMTP-BF16.gguf \
  --mmproj mmproj-Ornith-1.0-35B-BF16.gguf \
  --host 0.0.0.0 --port 8080 --jinja

For a Blackwell (RTX 50xx) build with native FP4 acceleration, compile llama.cpp with CUDA 12.8+ and -DCMAKE_CUDA_ARCHITECTURES=120. -ngl 999 offloads all layers; -c 262144 uses the full context.

This is a thinking model. Reasoning is emitted inside <think>…</think>. To disable thinking for a turn, pass "chat_template_kwargs": {"enable_thinking": false} in the request body.

Vision

The model is multimodal (image-text-to-text). Image input requires the separate mmproj file via --mmproj. Verified on llama.cpp with a synthetic image (the model correctly described the shape and color). Loading the mmproj has negligible impact on text-generation throughput (see benchmarks).

Benchmarks

RTX 5090 (32 GB), llama.cpp b9812 (0e53b82a9, MSVC 19.50, sm_120a, BLACKWELL_NATIVE_FP4=1), llama-benchy (pp = 512/4096, tg = 512, runs = 3, --latency-mode generation), tokenizer deepreinforce-ai/Ornith-1.0-35B, ctx = 262144, KV cache q8_0. Autoregressive (no spec decoding).

Mode	pp	Prefill (pp) tok/s	Generation (tg) tok/s	Peak tg
Text	512	6539.84 ± 84.57	193.58 ± 3.20	194.00
Text	4096	7754.81 ± 288.02	193.75 ± 1.92	194.33
Vision (+mmproj)	512	6076.30 ± 335.59	188.55 ± 1.97	189.00
Vision (+mmproj)	4096	7674.93 ± 86.51	190.58 ± 0.24	191.00

Coherence test PASSED in all runs; generation latency ≈ 112–125 ms.

Quantization / conversion notes

Converted with llama.cpp's convert_hf_to_gguf.py directly from the sakamakismile NVFP4 checkpoint (compressed-tensors, format: nvfp4-pack-quantized), which is auto-detected and re-packed into GGML_TYPE_NVFP4 — no de-quantization to full precision.

--outtype bf16 (not Q4_K). With bf16, the NVFP4 body is preserved and the large 2-D weights (token_embd, lm_head) stay at BF16; only small 1-D tensors (norms, biases, router gate, scales) are F32. There is no wasteful F32 blow-up of the big weights, so a follow-up llama-quantize pass is not required to reach a reasonable size (19.60 GiB).
--no-mtp. The checkpoint's config.json declares mtp_num_hidden_layers: 1 but ships no MTP tensors; --no-mtp keeps block_count = 40 and avoids requesting an absent MTP head.
Tensor make-up: NVFP4 × 430, F32 × 1161 (scales / norms / router gate), BF16 × 2 (token_embd, lm_head).

Speed/quality trade-off of BF16 output: keeping lm_head at BF16 (~1.0 GiB) costs roughly 14 % of generation throughput versus a fully quantized build (this model ≈ 193 tok/s vs Q4_K_M ≈ 223 tok/s on the same hardware), because the output projection over the ~248k-token vocabulary is read every decoding step. This build prioritizes lossless embeddings/output; for speed, Q6_K quantization of the output layer via llama-quantize is required.
