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)
KV Cache + Overhead ≈ 2.2 GB (at full 33K context)
VRAM usage by quantization
Q4_K_M5.0 GBQ4_K_M + full context6.8 GB- 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_M (5.8 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 3.6 GB.

- Can I run VulnLLM R 7B on a Mac?
VulnLLM R 7B requires at least 3.6 GB at Q2_K, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run VulnLLM R 7B locally?
Yes — VulnLLM R 7B can run locally on consumer hardware. At Q4_K_M quantization it needs 5.0 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is VulnLLM R 7B?
At Q4_K_M, VulnLLM R 7B can reach ~584 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~131 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: AMD Instinct MI300X → 5300 ÷ 5.0 × 0.55 = ~584 tok/s
Estimated speed at Q4_K_M (5.0 GB)
~584 tok/s~131 tok/s~437 tok/s~361 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of VulnLLM R 7B?
At Q4_K_M, the download is about 4.57 GB. The full-precision BF16 version is 15.23 GB. The smallest option (Q2_K) is 3.24 GB.
- Which GPUs can run VulnLLM R 7B?
35 consumer GPUs can run VulnLLM R 7B at Q4_K_M (5.0 GB). Top options include AMD Radeon RX 6700 XT, AMD Radeon RX 6800, AMD Radeon RX 6800 XT. 35 GPUs have plenty of headroom for comfortable inference.
- Which devices can run VulnLLM R 7B?
