The tooling answer the community asked for. “Seems good for chat, but it’s completely unusable with tools.”— Community feedback on Apex CORE-Ultra is the fix. Built on Qwen3.6-27B — the architecture the community specifically requested — and fine-tuned via SFT on 2,541 real-world bug bounty reports, CVE writeups, and offensive security research. It generates complete, functional, self-contained artifacts. Every time.
https://huggingface.co/BugTraceAI/BugTraceAI-CORE-Ultra-27B-Q6#%F0%9F%94%A7-what-is-a-tooling-model🔧 What is a Tooling Model?
Atooling modelis optimized for generating complete, executable artifacts rather than explaining concepts. When you ask it for a Nuclei template, you get a ready-to-run YAML. When you ask for a CVE PoC, you get a working Python script. When you ask for a code review, you get CVSS scores and a bypass exploit — not a paragraph about why the vulnerability is dangerous.
This is fundamentally different from areasoning model(like Apex), which excels at multi-step analysis, threat modeling, and chain-of-thought investigation. Both are valuable — but they solve different problems:

https://huggingface.co/BugTraceAI/BugTraceAI-CORE-Ultra-27B-Q6#%EF%BF%BD-minimum-hardware-requirements� Minimum Hardware Requirements
Getting a 27B model running well on consumer hardware is not trivial — it requires careful quantization. The IMatrix-guided Q4_K_S used here preserves quality in the most critical weight layers, so you get near-F16 performance at a fraction of the VRAM cost.
Q4_K_S — 15 GB (Recommended)
- Minimum:RTX 3090 (24 GB VRAM)— full GPU offload, fast inference
- RTX 4090 (24 GB) — same, slightly faster
- RTX 4080 (16 GB) — runs with reduced context (2048–4096)
- A4000 (16 GB) — workstation-grade, solid for pipelines
- 2× RTX 3060 (12 GB) — split layers across GPUs with
\-tsflag - CPU fallback: 64 GB+ RAM — slower but fully functional
Q6_K — 21 GB (High Fidelity)
- Minimum:RTX 3090 / A5000 (24 GB VRAM)— tight fit, recommended 4096 ctx
- A6000 (48 GB) — comfortable full offload
- H100 / A100 (80 GB) — server-grade, full context at speed
Practical tip for llama-server:
# RTX 3090/4090 — full GPU offload
./llama-server -m model.gguf -ngl 99 -c 4096 --port 8080
# RTX 4080 16GB — partial offload
./llama-server -m model.gguf -ngl 28 -c 2048 --port 8080
The fact that this model runs on a single consumer GPU is the result of significant quantization work — IMatrix calibration on a domain-specific security corpus ensures the quality loss is minimal where it matters most.
