Frequently Asked Questions
How much VRAM does LLaMmlein 1B Prerelease need?
LLaMmlein 1B Prerelease requires 1.0 GB of VRAM at Q4_K_M, or 2.5 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 1.1B × 4.8 bits ÷ 8 = 0.7 GB
KV Cache + Overhead ≈ 0.3 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.
VRAM usage by quantization
What's the best quantization for LLaMmlein 1B Prerelease?
For LLaMmlein 1B Prerelease, Q4_K_M (1.0 GB) offers the best balance of quality and VRAM usage. Q5_K_M (1.1 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 0.8 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run LLaMmlein 1B Prerelease on a Mac?
Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run LLaMmlein 1B Prerelease. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 1.0 GB of usable unified memory (RAM minus macOS overhead).
Can I run LLaMmlein 1B Prerelease locally?
Yes — LLaMmlein 1B Prerelease can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is LLaMmlein 1B Prerelease?
At Q4_K_M, LLaMmlein 1B Prerelease can reach ~4753 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~649 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 ÷ 1.01 × 0.65 = ~5149 tok/s
Estimated speed at Q4_K_M (1.0 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of LLaMmlein 1B Prerelease?
At Q4_K_M, the download is about 0.66 GB. The full-precision BF16 version is 2.20 GB. The smallest option (Q2_K) is 0.47 GB.
Which GPUs can run LLaMmlein 1B Prerelease?
52 consumer GPUs can run LLaMmlein 1B Prerelease at Q4_K_M. Top options include AMD Radeon RX 6700 XT, AMD Radeon RX 6800, AMD Radeon RX 6800 XT. 52 GPUs have plenty of headroom for comfortable inference.
Which devices can run LLaMmlein 1B Prerelease?
163 devices with unified memory can run LLaMmlein 1B Prerelease at Q4_K_M (1.0 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).
