Frequently Asked Questions
How much VRAM does MoziAI 27B MTP need?
MoziAI 27B MTP requires 16.9 GB of VRAM at Q4_K_M, or 54.8 GB at BF16. Full 262K context adds up to 13.9 GB (30.8 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 27B × 4.8 bits ÷ 8 = 16.2 GB
KV Cache + Overhead ≈ 0.8 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 ≈ 14.6 GB (at full 262K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 4090 run MoziAI 27B MTP?
Yes, at Q6_K (23.0 GB) or lower. Higher quantizations like Q8_0 (27.8 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
What's the best quantization for MoziAI 27B MTP?
For MoziAI 27B MTP, Q4_K_M (16.9 GB) offers the best balance of quality and VRAM usage. Q5_K_M (20.0 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 12.2 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run MoziAI 27B MTP on a Mac?
Yes — MacBook Pro 14" M3 Pro (18 GB) and 108 other Macs can run MoziAI 27B MTP, the smallest at Q3_K_M. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 16.9 GB of usable unified memory (RAM minus macOS overhead), from Mac Mini M5 Pro (24 GB).
Can I run MoziAI 27B MTP locally?
Yes — MoziAI 27B MTP can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is MoziAI 27B MTP?
At Q4_K_M, MoziAI 27B MTP can reach ~283 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~39 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 ÷ 16.95 × 0.65 = ~307 tok/s
Estimated speed at Q4_K_M (16.9 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of MoziAI 27B MTP?
At Q4_K_M, the download is about 16.20 GB. The full-precision BF16 version is 54.00 GB. The smallest option (Q2_K) is 11.47 GB.
Which GPUs can run MoziAI 27B MTP?
8 consumer GPUs can run MoziAI 27B MTP at Q4_K_M. Top options include NVIDIA GeForce RTX 5090, AMD Radeon RX 7900 XT, AMD Radeon RX 7900 XTX. 1 GPU has plenty of headroom for comfortable inference.
Which devices can run MoziAI 27B MTP?
122 devices with unified memory can run MoziAI 27B MTP at Q4_K_M (16.9 GB), including AMD Ryzen AI 9 HX 370 (Strix Point) Laptop, ASUS Ascent GX10, Beelink GTR9 Pro (Ryzen AI Max+ 395, 128 GB), Framework Desktop (Ryzen AI Max+ 395, 128 GB).
