DeepSeek-V4-Flash-Vision-Exp Abliterated

[!WARNING] Experimental research release. Text and focused image smoke tests pass, but broader quality, safety, and production-runtime evaluation remains pending.

This catalog contains the native abliterated checkpoint and two DS4 GGUF profiles. Both GGUF receivers use tensor types accepted by antirez/ds4 main; neither requires the legacy Python vision sidecar for current native vision.

Basic128-Routed-IQ2_M uses the closest familiar BPW class for the complete bundle: 2.915 BPW overall, close to llama.cpp's documented 2.9294 BPW for IQ2_M. The routed-expert subset averages 2.715 BPW, close to IQ2_S. This is a custom mixed recipe rather than llama.cpp's exact IQ2_M preset: routed gate/up tensors use IQ2_XXS, routed down tensors use Q2_K, ten routed layers retain MXFP4, and non-routed tensors include F32, F16, and Q8_0. See the llama.cpp quantization table for the reference BPW classes.

Runtime compatibility

The documented upstream baseline is antirez/ds4 main commit 110afdd8886586f18fc9b28bc5533152dd10e728.

Current upstream main has one Metal caveat: SSD prefill remaps receiver spans by discarding the separately mapped vision encoder. The model is accepted and text works, but native image prefill fails when --vision and --ssd-streaming are combined. The isolated upstream-ready fix is 17799146 on branch metal-vision-ssd-streaming-map; it is also included in ds4-flash-vision as 164bb227.

Portable setup

The commands below assume that the model repository and DS4 checkout are sibling directories. If your layout differs, set MODEL_REPO to the appropriate path relative to the DS4 checkout. No machine-specific paths are required.

For the documented upstream baseline:

git clone https://github.com/antirez/ds4.git
cd ds4
git checkout 110afdd8886586f18fc9b28bc5533152dd10e728
make -j ds4-server
MODEL_REPO="../DeepSeek-V4-Flash-Vision-Exp-Abliterated"

For full reference-profile vision support and the additional server fixes:

git clone --branch ds4-flash-vision --single-branch \
  https://github.com/apetersson/ds4.git ds4-flash-vision
cd ds4-flash-vision
make -j ds4-server
MODEL_REPO="../DeepSeek-V4-Flash-Vision-Exp-Abliterated"

Keep the selected checkout open for the launch commands that follow.

Reference profile

Text with the upstream baseline

The reference receiver does not fit in 128 GiB without SSD streaming. The upstream baseline command is therefore text-only because of the SSD/native- vision mapping issue described above:

./ds4-server \
  --model "${MODEL_REPO}/Reference-Native-GGUF/DeepSeek-V4-Flash-Vision-Exp-Abliterated-Reference-MainCompat-F16-Q8-MXFP4.gguf" \
  --metal \
  --ctx 2048 \
  --tokens 4000 \
  --prefill-chunk 512 \
  --ssd-streaming \
  --ssd-streaming-cache-experts 48GB \
  --host 127.0.0.1 \
  --port 18080

Text and images with ds4-flash-vision

Use the ds4-flash-vision checkout for the complete reference path on a 128 GiB Mac:

./ds4-server \
  --model "${MODEL_REPO}/Reference-Native-GGUF/DeepSeek-V4-Flash-Vision-Exp-Abliterated-Reference-MainCompat-F16-Q8-MXFP4.gguf" \
  --vision "${MODEL_REPO}/Reference-Native-GGUF/mmproj-DeepSeek-V4-Flash-Vision-Exp-F16.gguf" \
  --metal \
  --ctx 2048 \
  --tokens 4000 \
  --prefill-chunk 512 \
  --ssd-streaming \
  --ssd-streaming-cache-experts 48GB \
  --host 127.0.0.1 \
  --port 18080

Validation at 164bb227 returned OK for the text smoke test and correctly identified an Earth image. The server planned 52.39 GiB at --ctx 2048 with a 512-token prefill chunk. SSD-streamed decoding is expected to be slow because uncached experts must be read from storage.

Basic128 resident profile

The 95.76 GiB receiver fits in memory on the tested 128 GiB M1 Ultra, avoids SSD expert misses, and supports native images with the upstream baseline:

./ds4-server \
  --model "${MODEL_REPO}/Basic128-Routed-IQ2_M/DeepSeek-V4-Flash-Vision-Exp-Abliterated-Basic128-Routed-IQ2_M.gguf" \
  --vision "${MODEL_REPO}/Basic128-Routed-IQ2_M/mmproj-DeepSeek-V4-Flash-Vision-Exp-F16.gguf" \
  --metal \
  --ctx 32000 \
  --tokens 4000 \
  --prefill-chunk 1024 \
  --host 127.0.0.1 \
  --port 18080

At 32K context, this configuration planned 96.17 GiB on the tested M1 Ultra. Text generation reached about 23.4 tok/s, and the native image smoke test correctly identified an Earth image. If Metal reports insufficient memory, close other GPU-heavy applications, reduce --ctx, or reduce --prefill-chunk.

The same command works with ds4-flash-vision, which additionally provides conditional /v1/models image metadata, incremental tool-enabled answer streaming, M1 prefill optimizations, and the vision/SSD mapping fix. The Basic128 profile should normally remain resident; add the following options only when memory is constrained:

--ssd-streaming --ssd-streaming-cache-experts 48GB

Sending an image

IMAGE_B64="$(base64 < image.png | tr -d '\n')"
curl http://127.0.0.1:18080/v1/chat/completions \
  -H 'Content-Type: application/json' \
  -d "{\"messages\":[{\"role\":\"user\",\"content\":[
        {\"type\":\"text\",\"text\":\"Describe this image.\"},
        {\"type\":\"image_url\",\"image_url\":{
          \"url\":\"data:image/png;base64,$IMAGE_B64\"}}
      ]}],\"max_tokens\":128}"

Conversion and provenance

The reference receiver was minimally adapted for stock main rather than fully requantized: 129 routed-expert and 559 other compatible tensors were copied byte-for-byte, 338 F32 plain/control tensors became F16, and 345 F16 dense projections became Q8_0. The original incompatible 164.7 GB source-preserving receiver is no longer published in this catalog.

The Basic128 receiver similarly preserves every routed-expert payload from its source quant. Its expert layout is 66 IQ2_XXS gate/up tensors, 33 Q2_K down tensors, and 30 MXFP4 tensors. See each variant folder for checksums and its machine-readable build manifest.

This is a rank-1 abliterated derivative of deepseek-ai/DeepSeek-V4-Flash-Vision-Exp. It was produced by targeted projection edits, not gradient fine-tuning. Hugging Face uses the finetune parent relation because it has no generic model-surgery relation.
