Frequently Asked Questions
How much VRAM does Starling LM 7B Alpha need?
Starling LM 7B Alpha requires 4.9 GB of VRAM at Q4_K_M, or 15.1 GB at BF16. Full 8K context adds up to 0.8 GB (5.7 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 7.2B × 4.8 bits ÷ 8 = 4.3 GB
KV Cache + Overhead ≈ 0.6 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 ≈ 1.4 GB (at full 8K context)
VRAM usage by quantization
What's the best quantization for Starling LM 7B Alpha?
For Starling LM 7B Alpha, Q4_K_M (4.9 GB) offers the best balance of quality and VRAM usage. Q5_K_M (5.7 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 3.6 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Starling LM 7B Alpha on a Mac?
Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Starling LM 7B Alpha, the smallest at Q2_K. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 4.9 GB of usable unified memory (RAM minus macOS overhead), from Mac Mini M2 Pro (16 GB).
Can I run Starling LM 7B Alpha locally?
Yes — Starling LM 7B Alpha can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Starling LM 7B Alpha?
At Q4_K_M, Starling LM 7B Alpha can reach ~978 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~133 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 ÷ 4.91 × 0.65 = ~1059 tok/s
Estimated speed at Q4_K_M (4.9 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Starling LM 7B Alpha?
At Q4_K_M, the download is about 4.35 GB. The full-precision BF16 version is 14.48 GB. The smallest option (Q2_K) is 3.08 GB.
Which GPUs can run Starling LM 7B Alpha?
52 consumer GPUs can run Starling LM 7B Alpha 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 Starling LM 7B Alpha?
151 devices with unified memory can run Starling LM 7B Alpha at Q4_K_M (4.9 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).
