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)
KV Cache + Overhead ≈ 0.6 GB (at full 131K context)
VRAM usage by quantization
Q4_K_M0.5 GBQ4_K_M + full context0.7 GB- 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.

- Can I run Tiny Mixtral on a Mac?
Tiny Mixtral requires at least 0.4 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 Tiny Mixtral locally?
Yes — Tiny Mixtral can run locally on consumer hardware. At Q4_K_M quantization it needs 0.5 GB of VRAM. 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 = (bandwidth GB/s ÷ model GB) × efficiency
Example: NVIDIA B200 → 8000 ÷ 0.5 × 0.65 = ~6656 tok/s
Estimated speed at Q4_K_M (0.5 GB)
~6656 tok/s~2329 tok/s~6656 tok/s~5692 tok/sReal-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 (0.5 GB). 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?
59 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, Apple iPhone 17 Pro, Asus ROG Flow Z13 (2025, Ryzen AI Max+ 395, 128 GB).
