Every quant, against this card

Weight bytes are the size of the real published file wherever one exists — 1 of these6 rows are measured from the published checkpoint, the rest computed from the parameter count. Max context is what the KV cache can grow to in whatever memory the weights leave behind, capped at the 128k tokens this model was trained to address.

What the context actually costs

The KV cache is 2 · layers · kv_heads · head_dim bytes per token per element — 2 · 40 · 8 · 128 · 2 B = 160.0 KiB. It depends on the key/value head count, not the attention-head count and not the parameter count. This model shares 8 KV heads across 32 query heads, which divides the cache by 4 against multi-head attention.

Context	KV cache (FP16)	KV cache (8-bit)	Plus Q4_K_M weights
4,096	640 MiB	320 MiB	14.1 GiB
8,192	1.3 GiB	640 MiB	14.8 GiB
32,768	5.0 GiB	2.5 GiB	18.5 GiB
131,072	20.0 GiB	10.0 GiB	33.5 GiB

The speed ceiling, and where it comes from

Generating one token reads every active weight from memory once. At FP16 / BF16 that is 44.7 GiB, plus a pass over the KV cache. A Jetson AGX Orin (64GB) moves 204.8 GB/s, so the arithmetic ceiling is 4 tok/s. Treat it as a bound, not an estimate: attention overhead, kernel launches and imperfect memory access keep real runtimes at roughly 60–80% of it, and nothing pushes past it.

Where these numbers come from

The model

Parameters: 24,011,361,280
Layers: 40
Attention / KV heads: 32 / 8
Head dimension: 128
Trained context: 131,072
Checkpoint as published: 44.7 GiB

Read from dphn/Dolphin-Mistral-24B-Venice-Edition. The parameter count is the Hub's own total over the tensor shapes, not a figure taken from the model's name.

The accelerator

Memory: 64 GB LPDDR5 unified
Bandwidth: 204.8 GB/s
Assumed usable: 75% → 48.0 GiB

Capacity and bandwidth from the vendor's specification. The usable fraction is an assumption, not a spec: unified memory is shared with the OS and the display, and the GPU working-set cap is raisable on Apple silicon with `sudo sysctl iogpu.wired_limit_mb`.

Questions this pairing answers

How much VRAM does Dolphin Mistral 24B Venice Edition need?

44.7 GiB for the weights at FP16 — 24B parameters at two bytes each — and 13.5 GiB at Q4_K_M. The KV cache is on top of that and is not a fixed number: this model spends 160.0 KiB per token of context, so 8,192 tokens costs a further 1.3 GiB. A Jetson AGX Orin (64GB) makes 48.0 GiB of its 64 GB available on the assumption below.

Can a Jetson AGX Orin (64GB) run Dolphin Mistral 24B Venice Edition?

Yes, at full precision, though context is limited to 21k tokens. That is the weights and the KV cache together, against 48.0 GiB of usable memory.

How fast will Dolphin Mistral 24B Venice Edition run on a Jetson AGX Orin (64GB)?

No faster than 4 tokens/second at FP16 / BF16, and in practice below it. Decoding is memory-bound: every token reads all 44.7 GiB of weights plus the cache, and this card moves 204.8 GB/s. That division is the ceiling — no kernel, runtime or driver beats it, and a real runtime typically reaches 60–80% of it.

Why does the context length change how much memory Dolphin Mistral 24B Venice Edition needs?

Because the KV cache holds one key and one value vector per token, per layer, for the whole conversation, and it is allocated separately from the weights. This model has 40 layers and 8 key/value heads of 128 dimensions, shared across 32 query heads — grouped-query attention, which divides the cache by 4. That works out at 160.0 KiB per token. Parameter count tells you nothing about this number.

Method and limits. Weight bytes are the byte size of the real published file wherever one exists, and the model's exact parameter count times the published llama.cpp bits-per-weight where it does not. That distinction is on every row above and it matters at both ends: a sub-1B model's Q4_K_M file runs a third larger than the nominal figure because k-quants keep its embedding tables at higher precision, and an already-4-bit release cannot be quantized upward at all. The KV cache is 2 · layers · kv_heads · head_dim · bytes per token, summed over layers with each sliding-window layer capped at its window. The speed figure is a roofline bound, not a benchmark: bandwidth divided by bytes read per token, which no runtime exceeds and every runtime falls short of. The usable fraction of card memory is an assumption: 75% here, which is what this lane assumes for unified memory, where the OS and window server share the same pool — the other class assumes 92%, so it is not one number applied to every device. That is the only assumed input on this page; every other figure is computed from the model config and the card's published specification. Nothing on this page is written by a language model.

This checkpoint also carries a vision tower; its parameters are inside the totals above because they load whether or not you send it an image.
