KV cache uses a flat +20% context/overhead rule because this repo does not publish its config; exact numbers may differ for long contexts. MoE models keep all experts in memory — total size counts, not just active params. Longer context grows the KV cache — use the selector above.

Speed = decode tok/s estimated from memory bandwidth ÷ measured file size (× MoE active share). Real numbers vary ±30% by runtime and settings.
How much VRAM does inkling need?
The honest answer: 325.7 GB at the UD-IQ1_S quant with 8K context — that is the measured file size (270.2 GB) plus KV cache and runtime overhead. The smallest published build needs 325.7 GB; the lossless one needs 2.27 TB.
Can I run it with CPU offload?
Yes, if combined RAM+VRAM ≥ file size — but generation speed is limited by memory bandwidth. Expect roughly: DDR5 dual channel ~10-30 tok/s for small MoE actives, single digits for big ones, 0.1-1 tok/s when experts page from disk. CPU-only is fine for batch jobs, painful for chat.
Why do other sites show different numbers?
Most pages compute weights from a formula (params × bits/8). We use the actual file sizes published in GGUF repos, which include the embedding table, unquantized tensors, and container overhead — that is why our numbers can differ from a naive calculation.
FAQ
How much VRAM does inkling need?
The measured answer: 325.7 GB at the UD-IQ1_S quant with 8K context. The smallest published build needs 325.7 GB; the lossless (F16/BF16) build needs 2.27 TB. These are real GGUF file sizes from Hugging Face, not formula estimates.
Can I run inkling on a 24GB GPU (RTX 3090/4090)?
Not at UD-IQ1_S (325.7 GB). Nothing fits 24GB — the smallest build needs 325.7 GB. Use the hosted API or a smaller model.
How fast will inkling run?
Decode speed is memory-bandwidth-bound. At UD-IQ1_S: roughly 3 tok/s on an RTX 4090, 3 tok/s on an RTX 3090, 1 tok/s on an M-series Mac with 128GB, and 0.1 tok/s on CPU with dual-channel DDR4 — estimates from measured file size, MoE active-parameter share and memory bandwidth.
Can I run inkling on CPU with system RAM?
Yes, if your usable RAM is at least the file size. At UD-IQ1_S you need ~325.7 GB of RAM. CPU generation is memory-bandwidth-bound: expect single-digit tok/s for large MoE models, 10-30 tok/s for small active params, and below 1 tok/s when experts page from disk.
Why do VRAM numbers for inkling differ between sites?
Most sites compute weights from a formula (params x bits/8). ModelFit uses the actual GGUF file sizes published on Hugging Face, which include the embedding table, unquantized tensors, and container overhead — so our numbers reflect what you really download and load.
