Which GPUs Can Run Nex N2.5 Mini Uncensored?
Q4_K_M · 23.2 GBNex N2.5 Mini Uncensored (Q4_K_M) requires 23.2 GB of VRAM to load the model weights. For comfortable inference with headroom for KV cache and system overhead, 31+ GB is recommended. 7 GPUs can run it, including NVIDIA GeForce RTX 5090.
All compatible consumer-level GPUs are running near their VRAM limit. You may also want to consider professional GPUs (e.g., NVIDIA A100, H100) which offer significantly more VRAM. For more headroom and better throughput, consider a multi-GPU configuration with tensor parallelism (supported by tools like vLLM, llama.cpp, or text-generation-inference).

Frequently Asked Questions
- How much VRAM does Nex N2.5 Mini Uncensored need?
Nex N2.5 Mini Uncensored requires 23.2 GB of VRAM at Q4_K_M, or 77.2 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 35.1B × 4.8 bits ÷ 8 = 21.1 GB
KV Cache + Overhead ≈ 2.1 GB (at 2K context + ~0.3 GB framework)
VRAM usage by quantization
Q4_K_M23.2 GB- Can NVIDIA GeForce RTX 4090 run Nex N2.5 Mini Uncensored?
Yes, at Q4_K_M (23.2 GB) or lower. Higher quantizations like Q5_K_M (27.5 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
- What's the best quantization for Nex N2.5 Mini Uncensored?
For Nex N2.5 Mini Uncensored, Q4_K_M (23.2 GB) offers the best balance of quality and VRAM usage. Q5_K_M (27.5 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 16.4 GB.

- Can I run Nex N2.5 Mini Uncensored on a Mac?
Nex N2.5 Mini Uncensored requires at least 16.4 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 Nex N2.5 Mini Uncensored locally?
Yes — Nex N2.5 Mini Uncensored can run locally on consumer hardware. At Q4_K_M quantization it needs 23.2 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Nex N2.5 Mini Uncensored?
At Q4_K_M, Nex N2.5 Mini Uncensored can reach ~207 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~28 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 ÷ 23.2 × 0.65 = ~224 tok/s
Estimated speed at Q4_K_M (23.2 GB)
~224 tok/s~28 tok/s~224 tok/s~207 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Nex N2.5 Mini Uncensored?
At Q4_K_M, the download is about 21.06 GB. The full-precision BF16 version is 70.21 GB. The smallest option (Q2_K) is 14.92 GB.
