Kimi Dev 72B — Hardware Requirements & GPU Compatibility
ChatCodeKimi 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 145.0 GB of VRAM at BF16. Full 131K context adds up to 42.3 GB (187.3 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 72B × 16 bits ÷ 8 = 144 GB
KV Cache + Overhead ≈ 1 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 43.3 GB (at full 131K context)
VRAM usage by quantization
BF16145.0 GBBF16 + full context187.3 GB- Can NVIDIA GeForce RTX 5090 run Kimi Dev 72B?
No — Kimi Dev 72B requires at least 145.0 GB at BF16, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
- Can I run Kimi Dev 72B on a Mac?
Kimi Dev 72B requires at least 145.0 GB at BF16, 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 Kimi Dev 72B locally?
Yes — Kimi Dev 72B can run locally on consumer hardware. At BF16 quantization it needs 145.0 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Kimi Dev 72B?
At BF16, Kimi Dev 72B can reach ~20 tok/s on AMD Instinct MI300X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: AMD Instinct MI300X → 5300 ÷ 145.0 × 0.55 = ~20 tok/s
Estimated speed at BF16 (145.0 GB)
~20 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
