RED-SNOW 5.3 FLASH - GGUF

GGUF quants of Blackfrost-AI/RED-SNOW-5.3-FLASH-BF16 - a red-team operations model built on a GLM-5.3-Flash (glm5_next) foundation with targeted security adaptation.

Full-functionality GGUF exports for llama.cpp: text + vision included (the GLM-5.3 vision tower ships as a separate mmproj file, keeping every quant pairable with it). Every file was smoke-tested end to end before upload - text runs with llama-cli, vision with llama-server --mmproj.

The model

RED-SNOW 5.3 FLASH is built for authorized offensive-security work: attack-path reasoning, cross-domain operations (identity, cloud, network, app, endpoint, OT), exploit and tradecraft analysis, detection-aware execution, and purple-team handoff. See the base model card for the full picture.

Architecture highlights that matter for inference:

• MoE: 45 layers, 288 routed experts (8 active), 1 shared expert, ~321B total params
• MLA (nope-only) + DSA sparse-attention indexer with k-pool compression
• KDA linear attention on most layers (short-conv + gated delta net)
• mHC hyper-connections
• MTP (nextn) layer - shipped in-file in every GGUF for speculative decoding

Quants

MTP speculative decoding ships in-file: every main GGUF carries the NextN block, enabled at runtime with --spec-type draft-mtp. No separate draft download is needed. The MTP head boosts decode throughput for free.

Vision

Full multimodal support: the GLM-5.3 vision tower (glm5v projector) ships as mmproj-RED-SNOW-5.3-FLASH-f16.gguf and pairs with any of the quants above. Screenshots, target UIs, logs, and diagrams all work through the standard OpenAI-compatible image_url content parts:

llama-server -m RED-SNOW-5.3-FLASH-Q4_K_M.gguf \
  --mmproj mmproj-RED-SNOW-5.3-FLASH-f16.gguf \
  -ngl 99 --jinja --port 8080

The vision tower is kept separate so each quant stays small; the base model's multimodal behavior is preserved bit-for-bit (F16 tower).

Usage

Requires a llama.cpp build with glm5_next / Glm5NextForConditionalGeneration support, including the glm5v mmproj projector for vision.

# chat
llama-cli -m RED-SNOW-5.3-FLASH-Q4_K_M.gguf -ngl 99 --jinja

# server with in-file MTP speculative decoding + vision
llama-server -m RED-SNOW-5.3-FLASH-Q4_K_M.gguf \
  --spec-type draft-mtp \
  --mmproj mmproj-RED-SNOW-5.3-FLASH-f16.gguf \
  -ngl 99 --jinja --port 8080

The chat template preserves GLM's visible-answer/reasoning split and supports thinking-on and thinking-off generation.

How these were made

• Quantized with llama.cpp ggml K-quant kernels, streaming per-tensor from the BF16 safetensors via HTTP range requests (peak RAM of one tensor), so quality is identical to a conventional offline quantize.
• Embeddings/output at Q8_0 (Q6_K for Q4_K_M), sensitive indexer/ssm/hc tensors kept at higher precision on the dynamic builds, first and last eighth of the layers boosted on UD builds.
• Smoke test per file: llama-cli generation check before release, plus a llama-server --mmproj vision check (image color identification) for the mmproj file. Records live in smoke/.

Smoke tests

Every GGUF in this repo passed a generation smoke test (a coding prompt that must produce a correct function) before upload. Each record in smoke/ is a small Python file with the full transcript; you can verify one like this:

def smoke_ok(record_path: str) -> bool:
    """Check a smoke/ record: true if the quant passed its smoke test."""
    record = open(record_path).read()
    return "SMOKE_OK = True" in record and "return a + b" in record

Intended use

Authorized offensive-security work only: scoped engagements, labs, CTFs, cyber ranges, and research. Keep a human operator in control of scope, targets, credentials, and destructive actions; validate findings against real systems. You are responsible for operating within the law and within your authorization.
