Frequently Asked Questions
- How much VRAM does Inkling Small DSpark Preview need?
Inkling Small DSpark Preview requires 1.2 GB of VRAM at Q4_K_M, or 3.1 GB at BF16. Full 1049K context adds up to 21.4 GB (22.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 1.4B × 4.8 bits ÷ 8 = 0.8 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 21.8 GB (at full 1049K context)
VRAM usage by quantization
Q4_K_M1.2 GBQ4_K_M + full context22.6 GB- What's the best quantization for Inkling Small DSpark Preview?
For Inkling Small DSpark Preview, Q4_K_M (1.2 GB) offers the best balance of quality and VRAM usage. Q5_K_M (1.3 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 0.9 GB.

- Can I run Inkling Small DSpark Preview on a Mac?
Inkling Small DSpark Preview requires at least 0.9 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 Inkling Small DSpark Preview locally?
Yes — Inkling Small DSpark Preview can run locally on consumer hardware. At Q4_K_M quantization it needs 1.2 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Inkling Small DSpark Preview?
At Q4_K_M, Inkling Small DSpark Preview can reach ~4068 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~555 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 ÷ 1.2 × 0.65 = ~4407 tok/s
Estimated speed at Q4_K_M (1.2 GB)
~4407 tok/s~555 tok/s~4407 tok/s~4068 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Inkling Small DSpark Preview?
At Q4_K_M, the download is about 0.84 GB. The full-precision BF16 version is 2.79 GB. The smallest option (Q2_K) is 0.59 GB.
