Frequently Asked Questions
- How much VRAM does Titus CybersecurityLLM v1.0 MLX 4Bit need?
Titus CybersecurityLLM v1.0 MLX 4Bit requires 21.2 GB of VRAM at Q4_K_M. Full 262K context adds up to 10.6 GB (31.8 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 34.7B × 4.8 bits ÷ 8 = 20.8 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 11 GB (at full 262K context)
VRAM usage by quantization
Q4_K_M21.2 GBQ4_K_M + full context31.8 GB- Can I run Titus CybersecurityLLM v1.0 MLX 4Bit on a Mac?
Titus CybersecurityLLM v1.0 MLX 4Bit requires at least 21.2 GB at Q4_K_M, 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 Titus CybersecurityLLM v1.0 MLX 4Bit locally?
Yes — Titus CybersecurityLLM v1.0 MLX 4Bit can run locally on consumer hardware. At Q4_K_M quantization it needs 21.2 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Titus CybersecurityLLM v1.0 MLX 4Bit?
At Q4_K_M, Titus CybersecurityLLM v1.0 MLX 4Bit can reach ~138 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~31 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 ÷ 21.2 × 0.55 = ~138 tok/s
Estimated speed at Q4_K_M (21.2 GB)
~138 tok/s~31 tok/s~103 tok/s~85 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
