YuhoLens-14B GGUF

GGUF-quantized release of javierdejesusda/yuholens-14b for offline inference via llama.cpp. The BF16 source is a full-parameter SFT of pfnet/nekomata-14b-pfn-qfin (Qwen1, 14B, Japanese-finance CPT) on teacher-bootstrapped English investor memos derived from SakanaAI/EDINET-Bench.

Sizes are the actual on-disk byte counts; quoted GB values use 1024³.

Smoke test

The Q3_K_M quant has been smoke-tested on an NVIDIA RTX 4070 Laptop (8 GB VRAM, compute 8.9) using llama-completion from llama.cpp build b8966.

• Prompt: ChatML-wrapped Yuho fixture with the YuhoLens system prompt (see Prompt format below).
• Settings: --n-gpu-layers 99 -c 2048 --temp 0.1 --top-p 0.9 --repeat-penalty 1.15.
• Throughput: prompt eval 65.5 tok/s, generation 12.2 tok/s.
• VRAM occupancy: ~7.0 GB model + ~1.6 GB context + ~0.3 GB compute, fits within the 8.0 GB card.
• Output: coherent English investor memo with section headings (Executive summary, Going-concern assessment, Accrual quality, ...) following the SFT teacher template.

Q4_K_M and larger quants exceed 8 GB VRAM and require either a 12 GB+ GPU or partial CPU offload (--n-gpu-layers < 99).

Quickstart

# Q3_K_M, fits 8 GB GPU
llama-completion \
  -m yuholens-14b-Q3_K_M.gguf \
  -f your_prompt.txt \
  --n-gpu-layers 99 \
  -c 2048 \
  --temp 0.1 --top-p 0.9 --repeat-penalty 1.15 \
  -n 512 \
  --no-display-prompt

For larger quants on a smaller GPU, drop --n-gpu-layers to a value that fits VRAM (e.g. --n-gpu-layers 30 for Q4_K_M on 8 GB).

Prompt format

YuhoLens-14B was fine-tuned on Qwen1 ChatML with a fixed system prompt. Raw Japanese Yuho text without the wrapper produces Japanese continuations instead of English memos. Wrap inputs as:

<|im_start|>system
{SYSTEM_PROMPT}<|im_end|>
<|im_start|>user
Company metadata (JSON):
{...}

Balance sheet (JSON):
{...}

P&L (JSON):
{...}

Cash flow (JSON):
{...}

Japanese annual-report text (truncated at ~20K chars):
<<<
{Japanese Yuho text}
>>>

Produce the two-page English investor memo now.<|im_end|>
<|im_start|>assistant

The full system prompt is published in the BF16 model card and in src/yuholens/training/teacher.py of the GitHub repo. A pre-formatted smoke fixture is included in the GitHub repo at data/sample/smoke_prompt_chatml.txt.

Build provenance

Source checkpoint: output/yuholens-14b-sft/checkpoint-212 (28.3 GB BF16 safetensors), tagged at git commit f903174.

Built with:

• llama.cpp commit b8966 (7b8443ac7), Windows CUDA 12.4 prebuilt binaries.
• Convert script convert_hf_to_gguf.py patched locally to fall back to an inline GPT-2 byte-to-unicode mapping when transformers ≥ 5.x removes bytes_to_unicode. See the GitHub repo for the patch.
• llama-quantize invoked with --override-kv qwen.attention.layer_norm_rms_epsilon=float:0.000001 because Qwen1 uses RMSNorm internally but its HF config exposes the field as layer_norm_epsilon; this override is now baked into scripts/build_gguf.sh.

Reproduce locally:

LLAMACPP_REPO=/path/to/llama.cpp \
LLAMACPP_BIN=/path/to/llama.cpp/build/bin \
  scripts/build_gguf.sh output/yuholens-14b-sft/checkpoint-212 data/eval/gguf

Limitations

• Output language asymmetry. The model emits English memos and expects Japanese Yuho input. Japanese output is unsupported by training distribution.
• Citation accuracy unaudited. The model produces inline (ref: '<span>' p.N) citations, but verbatim-correctness against the underlying Yuho text has not been audited.
• Quantization quality bands. Q3_K_M sacrifices some fidelity for the 8 GB VRAM target. Prefer Q4_K_M or higher when memory permits.
• Domain. Trained on Yuho 有価証券報告書 only. Earnings transcripts, 決算短信, and non-Japanese filings are out-of-scope.
• Not financial advice. Outputs are model-generated and may contain factual errors. Verify every material claim against the source.
