Frequently Asked Questions
How much VRAM does Veritas 8B Fact Checker Non Thinking 1.0 need?
Veritas 8B Fact Checker Non Thinking 1.0 requires 5.5 GB of VRAM at Q4_K_M, or 17.0 GB at BF16. Full 41K context adds up to 5.7 GB (11.3 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 8.2B × 4.8 bits ÷ 8 = 4.9 GB
KV Cache + Overhead ≈ 0.6 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 ≈ 6.4 GB (at full 41K context)
VRAM usage by quantization
What's the best quantization for Veritas 8B Fact Checker Non Thinking 1.0?
For Veritas 8B Fact Checker Non Thinking 1.0, Q4_K_M (5.5 GB) offers the best balance of quality and VRAM usage. Q5_K_M (6.4 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 4.1 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Veritas 8B Fact Checker Non Thinking 1.0 on a Mac?
Yes — Mac Mini M2 Pro (16 GB) and 133 other Macs can run Veritas 8B Fact Checker Non Thinking 1.0. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 5.5 GB of usable unified memory (RAM minus macOS overhead).
Can I run Veritas 8B Fact Checker Non Thinking 1.0 locally?
Yes — Veritas 8B Fact Checker Non Thinking 1.0 can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Veritas 8B Fact Checker Non Thinking 1.0?
At Q4_K_M, Veritas 8B Fact Checker Non Thinking 1.0 can reach ~870 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~119 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: NVIDIA B200 → 8000 ÷ 5.52 × 0.65 = ~942 tok/s
Estimated speed at Q4_K_M (5.5 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
