DeepSeek-V4-Flash — Vision Encoder

Give your self-hosted DeepSeek eyes.
Official production tower + projector for DeepSeek-V4-Flash-0731.

This repo is only the vision stack (about 900 MB total). The language model itself is still the upstream 0731 FP8 checkpoint (about 167 GB).

image  →  DeepEncoderV2 tower  →  projector  →  splice at token 129279
                                              →  DeepSeek-V4-Flash-0731

Serve it on 2× DGX Spark:

Download

hf download FlyCockpit/DeepSeek-V4-Flash-0731-vision \
  --local-dir $HOME/dsv4-vision-assets

Or pull just the two weight files:

hf download FlyCockpit/DeepSeek-V4-Flash-0731-vision \
  adapter/latest.pt \
  tower/deepencoder_v2_tower.safetensors \
  --local-dir $HOME/dsv4-vision-assets

Files

path	what	size	md5
`adapter/latest.pt`	use this — final projector	40 MB	`d9b3b3bda8f790ecf7cd5a98e6fb93a5`

Final training step: 4800. Layout: tiles=2 (257 / 769 / 1281 image tokens).

What it's for

Strength	Notes
UI / screenshot understanding	Primary target
Documents & on-screen text	Strong
Everyday photos	Decent
Click agents on arbitrary real UIs	Not claimed — see below

Synthetic GUI coordinate probes pass; real-page computer-use does not transfer cleanly yet. Full write-up lives in the playbook's capabilities doc.

Compatibility (important)

This encoder maps into 0731's embedding space.

base weights	works?
`deepseek-ai/DeepSeek-V4-Flash-0731`	yes
older Flash / DSpark / NVIDIA NVFP4 of the old line	no

Precision (FP8 vs a future 0731-matched quant) is fine. Different training lineage is not.
