Frequently Asked Questions
How much VRAM does Tiny Mixtral need?
Tiny Mixtral requires 0.5 GB of VRAM at Q4_K_M, or 0.8 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 247M × 4.8 bits ÷ 8 = 0.1 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 ≈ 0.6 GB (at full 131K context)
VRAM usage by quantization
What's the best quantization for Tiny Mixtral?
For Tiny Mixtral, Q4_K_M (0.5 GB) offers the best balance of quality and VRAM usage. Q5_K_M (0.5 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 0.4 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Tiny Mixtral on a Mac?
Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Tiny Mixtral. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 0.5 GB of usable unified memory (RAM minus macOS overhead).
Can I run Tiny Mixtral locally?
Yes — Tiny Mixtral can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Tiny Mixtral?
At Q4_K_M, Tiny Mixtral can reach ~2254 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~2329 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = 1000 ÷ (active GB ÷ (bandwidth GB/s × efficiency) × 1000 + layers × routing ms)
Mixture-of-Experts: just the active experts get read for each token, along with a fixed routing cost per layer.
Example: NVIDIA B200 → 0.2 GB active ÷ (8000 × 0.65) = 0.04024 ms, plus 2 layers × 0.055 ms = 0.11000 ms, so 1000 ÷ 0.15024 ms = ~6656 tok/s
Estimated speed at Q4_K_M (0.5 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Tiny Mixtral?
At Q4_K_M, the download is about 0.15 GB. The full-precision BF16 version is 0.49 GB. The smallest option (Q2_K) is 0.10 GB.
Which GPUs can run Tiny Mixtral?
52 consumer GPUs can run Tiny Mixtral at Q4_K_M. Top options include AMD Radeon RX 6700 XT, AMD Radeon RX 6800, AMD Radeon RX 6800 XT. 52 GPUs have plenty of headroom for comfortable inference.
Which devices can run Tiny Mixtral?
163 devices with unified memory can run Tiny Mixtral at Q4_K_M (0.5 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). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
