Cross-cutting rename of the current llama.cpp endpoint on the RTX 3090
(port 7771) from frank-small to frank-secondary:
- Service trio: scripts/{frank-small.env,frank-small.service,
serve-frank-small.sh,download-frank-small.sh} → frank-secondary.*
- Test: tests/frank_small_unit.bats → tests/frank_secondary_unit.bats
- Runbooks: serverAppConfigs-docs/LLM/frank-small-*.md →
frank-secondary-*.md (9 files); the FreeToken runbook stays
freetoken-frank-small.md (it documents the retired CUDA-era service)
- Identifiers: FRANK_SMALL→FRANK_SECONDARY, llm_small→llm_secondary,
LLM_SMALL_*→LLM_SECONDARY_*, deploy_llm_small→deploy_llm_secondary
- Historical references to the OLD frank-small (FreeToken/CUDA on the
3090, and the Dankserver service that became frank-medium) are
preserved verbatim — they describe what the service was called
at the time.

ComfyUI Qwen-Image Workflows
Two ready-to-load text-to-image workflows for the Qwen-Image 2.1 payload
already on Dankclaw, both proven end-to-end on 2026-10-05 by POSTing to the
live API on port 8188 and verifying the rendered PNG. The repo copies are the
source of truth; the host copies under /home/dank/comfyui-data/workflows/
are for convenience.

The workflows
Both are API-format JSON (ComfyUI 0.37 loads them via the UI's Load dialog
too): dankclaw/comfyui/workflows/ in the repo,
/home/dank/comfyui-data/workflows/ on the host. Node chain in both:
UNETLoader (int8_convrot) ──┐
CLIPLoader (qwen_image, w4a8) ─┤ CLIPTextEncode pos/neg
VAELoader (2.1 bf16) ────────┤
EmptySD3LatentImage ─────────┴─ KSampler ─ VAEDecode ─ SaveImage
Common sampler settings: cfg 1.0 (Qwen-Image 2.1 expects CFG-free
sampling), euler + simple, seed fixed in the file.
| Workflow | File | Shape | Steps | Made for |
|---|---|---|---|---|
| Art | qwen-image-2.1-t2i-art.json |
1024×1024 | 20 | General illustration/prose prompts |
| Legible text | qwen-image-2.1-t2i-legible-text.json |
832×1216 | 25 | Posters, captions, any in-image text |
Legible-text prompt recipe
Qwen-Image 2.1 is one of the best open-weight text renderers, but only if the prompt is written for it:
- Quote the exact strings:
large bold white text reading "SOLIDARITY OF THE SOVIET COMPUTER SYSTEMS"— quoted text is rendered literally. - Describe layout, not vibes: say centered / below it / large vs small, the typeface family (sans-serif), and the color.
- Say what NOT to draw: end with
no other words, no watermark. - Keep the negative side on
misspelled, warped letters, extra text(already in the workflow). - More steps help text: the text workflow uses 25 vs 20.
Verified render: SOLIDARITY OF THE SOVIET COMPUTER SYSTEMS + DANKCLAW DANKSERVER EST 2026 came back crisp and correctly spelled at 832×1216
(qwen21-text_00001_.png, 953 KB). One caveat from the same render: a
shorter secondary line is where misspellings creep in — proofread the first
render before shipping.
Driving it from the API
ComfyUI 0.37 requires the graph wrapped in a prompt key — a bare
{node-id: node} body gets {"error": {"type": "no_prompt"}} (verified
2026-10-05):
curl -s -X POST http://127.0.0.1:8188/prompt -H 'Content-Type: application/json' \
-d "$(python3 -c 'import json;print(json.dumps({"prompt": json.load(open("dankclaw/comfyui/workflows/qwen-image-2.1-t2i-art.json"))}))')"
# -> {"prompt_id": "...", ...}
curl -s http://127.0.0.1:8188/history/<prompt_id> # status.status_str == "success"
Outputs land in /home/dank/comfyui-data/output/. The queue is FIFO — the
two workflows above ran back-to-back unattended.
Note: the container's UI-saved workflows live in the ephemeral
/opt/ComfyUI/user layer and do NOT survive an image rebuild — hence the
host-side workflows/ dir and the repo copy.
Recommended additions
Quantized preferred, sized for the 8060S iGPU (GTT-backed; the RTX 3090 is frank-secondary's). All repos verified 2026-10-05. None are on disk yet.
| # | What | Repo | Grab | Size | Why |
|---|---|---|---|---|---|
| 1 | Lightning 8-step LoRA (T2I speed) | lightx2v/Qwen-Image-Lightning |
qwen_image_lightning_8steps_*.safetensors (LoRA) |
~1–2 GB | 20 steps → 8 with a LoraLoader node; 2–3× faster renders on the iGPU, negligible quality loss |
| 2 | Qwen-Image-Edit-2511 GGUF (image editing) | unsloth/Qwen-Image-Edit-2511-GGUF |
Q4_K_M (~13.2 GB) or Q4_0 (~11.9 GB) | ~12–13 GB | Unlocks img2img "edit this photo" workflows — a capability class the fleet has zero of; Q4 keeps it iGPU-friendly |
| 3 | DiffSynth ControlNets (structure control) | Comfy-Org/Qwen-Image-DiffSynth-ControlNets |
split_files/model_patches/ canny + depth |
~2–3 GB each | Pose/edge/depth-guided layouts — pairs with the legible-text workflow for exact poster composition. The QwenImageDiffsynthControlnet node is already in the running ComfyUI |
| 4 | Wan 2.2 TI2V-5B GGUF (first video model) | QuantStack/Wan2.2-TI2V-5B-GGUF |
Q4/Q5 GGUF (~6–8 GB) | ~6–8 GB | T2V+I2V in one dense 5B model; the gentlest on-ramp into video generation, runs in ComfyUI core (wan CLIP type is already in this build's loader enum) |
Placement: #1 → models/lora/ (create it), #2 → models/diffusion_models/,
#3 → models/controlnet/ (create it), #4 → models/diffusion_models/.
Fetch with scripts/download-frank-*.sh discipline (-f + byte-count +
sha256 checks) or a plain hf download with the token in the environment —
never on the command line.
Skip list: the original city96/Qwen-Image-gguf conversions (superseded by
the 2.1 files already on disk), and any BF16 of #2/#4 (the iGPU does not need
them at GTT capacity, and they double the disk bill).
