Kimi VL A3B Instruct — Hardware Requirements & GPU Compatibility

VisionFunctions

Kimi VL A3B Instruct is Moonshot AI's 16.4-billion-parameter mixture-of-experts vision-language model, with about 3 billion parameters active per token (the A3B in its name). Because only the active experts run for each token, it runs faster than a dense model of similar total size, though the full set of weights must still fit in memory. It pairs a native-resolution vision encoder with a language core built on Moonshot's Moonlight-16B-A3B model, supporting image and video understanding, OCR, multi-image reasoning, and agent-style tool use. At this size, local inference is practical on a single high-end consumer GPU once quantized. The model supports a 131K token context window, useful for long documents or video transcripts. It is released under the MIT license, one of the most permissive open licenses, and was published in April 2025.

Frequently Asked Questions

How much VRAM does Kimi VL A3B Instruct need?

Kimi VL A3B Instruct requires 10.6 GB of VRAM at Q4_K_M, or 33.6 GB at BF16. Full 131K context adds up to 3.6 GB (14.2 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 16.4B × 4.8 bits ÷ 8 = 9.8 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 ≈ 4.4 GB (at full 131K context)

Can I run Kimi VL A3B Instruct on a Mac?

Yes — Mac Mini M2 Pro (16 GB) and 133 other Macs can run Kimi VL A3B Instruct. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 10.6 GB of usable unified memory (RAM minus macOS overhead).

Can I run Kimi VL A3B Instruct locally?

Yes — Kimi VL A3B Instruct can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Kimi VL A3B Instruct?

At Q4_K_M, Kimi VL A3B Instruct can reach ~171 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~208 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 → 2.2 GB active ÷ (8000 × 0.65) = 0.4177 ms, plus 27 layers × 0.055 ms = 1.4850 ms, so 1000 ÷ 1.9027 ms = ~526 tok/s

Estimated speed at Q4_K_M (10.6 GB)

~526 tok/s
~208 tok/s
~526 tok/s
~462 tok/s

Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
