VulnLLM R 7B — Hardware Requirements & GPU Compatibility
ChatReasoning
VulnLLM R 7B is a security-focused model developed by UCSB-SURFI, built on the Qwen2.5-7B base and fine-tuned specifically for vulnerability analysis and security reasoning. With 7.6 billion parameters, it targets tasks like identifying code vulnerabilities, explaining security flaws, and reasoning about attack vectors. This model fills a niche for security researchers and developers who want a locally-hosted assistant for code auditing and vulnerability assessment without sending sensitive code to external APIs. Its specialized training gives it an edge over general-purpose models on security-related tasks, though it is not a replacement for professional security tools. Runs on consumer GPUs with 8 GB of VRAM at typical quantization levels.

Frequently Asked Questions
How much VRAM does VulnLLM R 7B need?
VulnLLM R 7B requires 5.0 GB of VRAM at Q4_K_M, or 15.7 GB at BF16. Full 33K context adds up to 1.8 GB (6.8 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 7.6B × 4.8 bits ÷ 8 = 4.6 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.
KV Cache + Overhead ≈ 2.2 GB (at full 33K context)
VRAM usage by quantization
What's the best quantization for VulnLLM R 7B?
For VulnLLM R 7B, Q4_K_M (5.0 GB) offers the best balance of quality and VRAM usage. Q5_K_S (5.7 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 2.5 GB.
