Kimi Dev 72B — Hardware Requirements & GPU Compatibility
ChatCodeFunctionsKimi Dev 72B is Moonshot AI's developer-focused model built on the Qwen2.5-72B architecture, specifically optimized for coding tasks, tool use, and agentic workflows. It combines strong general-purpose chat abilities with specialized developer capabilities, making it a compelling choice for software engineering assistance. At 72 billion parameters it requires substantial hardware, typically needing 40+ GB of VRAM at 4-bit quantization, which puts it in reach of dual consumer GPU setups or single professional cards like the A100 or RTX 6000 Ada. If you are primarily looking for a local coding assistant with strong reasoning skills, Kimi Dev is a top-tier option in the 70B class.

Frequently Asked Questions
How much VRAM does Kimi Dev 72B need?
Kimi Dev 72B requires 44.6 GB of VRAM at Q4_K_M, or 146.4 GB at BF16. Full 131K context adds up to 42.3 GB (86.9 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 72.7B × 4.8 bits ÷ 8 = 43.6 GB
KV Cache + Overhead ≈ 1 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 ≈ 43.3 GB (at full 131K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 4090 run Kimi Dev 72B?
Yes, at IQ2_S (23.7 GB) or lower. Higher quantizations like IQ2_M (25.5 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
What's the best quantization for Kimi Dev 72B?
For Kimi Dev 72B, Q4_K_M (44.6 GB) offers the best balance of quality and VRAM usage. Q5_0 (46.4 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 21.0 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Kimi Dev 72B on a Mac?
Yes — Mac Studio M1 Max (32 GB) and 84 other Macs can run Kimi Dev 72B, the smallest at IQ2_S. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 44.6 GB of usable unified memory (RAM minus macOS overhead), from Mac Pro M2 Ultra (64 GB).
