Frequently Asked Questions

How much VRAM does Laguna XS.2 need?

Laguna XS.2 requires 20.5 GB of VRAM at Q4_K_M, or 67.3 GB at BF16. Full 262K context adds up to 14.2 GB (34.7 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 33.4B × 4.8 bits ÷ 8 = 20.1 GB

KV Cache + Overhead ≈ 0.4 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 ≈ 14.6 GB (at full 262K context)

Can NVIDIA GeForce RTX 4090 run Laguna XS.2?

Yes, at Q4_K_M (20.5 GB) or lower. Higher quantizations like Q5_K_M (24.2 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.

What's the best quantization for Laguna XS.2?

For Laguna XS.2, Q4_K_M (20.5 GB) offers the best balance of quality and VRAM usage. Q5_K_M (24.2 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 14.6 GB.

Can I run Laguna XS.2 on a Mac?

Yes — Mac Mini M5 Pro (24 GB) and 106 other Macs can run Laguna XS.2. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 20.5 GB of usable unified memory (RAM minus macOS overhead).

Can I run Laguna XS.2 locally?

Yes — Laguna XS.2 can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Laguna XS.2?

At Q4_K_M, Laguna XS.2 can reach ~119 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~199 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 → 1.8 GB active ÷ (8000 × 0.65) = 0.36 ms, plus 40 layers × 0.055 ms = 2.20 ms, so 1000 ÷ 2.56 ms = ~391 tok/s

Estimated speed at Q4_K_M (20.5 GB)

~391 tok/s
~199 tok/s
~391 tok/s
~360 tok/s

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

What's the download size of Laguna XS.2?

At Q4_K_M, the download is about 20.07 GB. The full-precision BF16 version is 66.89 GB. The smallest option (Q2_K) is 14.21 GB.

Which GPUs can run Laguna XS.2?

7 consumer GPUs can run Laguna XS.2 at Q4_K_M. Top options include NVIDIA GeForce RTX 5090, AMD Radeon RX 7900 XTX, NVIDIA GeForce RTX 3090. 1 GPU has plenty of headroom for comfortable inference.

Which devices can run Laguna XS.2?

122 devices with unified memory can run Laguna XS.2 at Q4_K_M (20.5 GB), including AMD Ryzen AI 9 HX 370 (Strix Point) Laptop, ASUS Ascent GX10, Beelink GTR9 Pro (Ryzen AI Max+ 395, 128 GB), Framework Desktop (Ryzen AI Max+ 395, 128 GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
