Holo4-35B-A3B: how much VRAM does it need?

This page was written and translated automatically by AI and checked by software against its sources, with no human editing. Specifications come from the sources listed; memory requirements and speeds are estimates calculated with published formulas. How we use AI

Holo4-35B-A3B is a mixture-of-experts model with 34.7B parameters, of which about 2.9B are active per token (input embedding lookup not counted). At Q4_K_M with a context of 8,192 tokens, a single GPU needs 23.3 GiB of available memory for the result to be “Fits”.

Key facts

GGUF files and memory needed

All quantizations come from one GGUF repository at one pinned revision: bartowski/Hcompany_Holo4-35B-A3B-GGUF@2ef8a87

GPUs that can run Holo4-35B-A3B

“Fits” means llama.cpp's default --fit load check would place all layers on the GPU: our estimate of llama.cpp's buffers, plus its error margin, plus llama.cpp's 1 GiB per-card reserve, is within the memory counted as available. It does not promise that peak memory while generating fits. How results are decided

Borderline GPUs

GPUs where it doesn’t fit on one card

GPUs without a verdict

• CUDA (NVIDIA): llama.cpp, CUDA back end (NVIDIA discrete GPU), all layers on the GPU, Flash Attention on, micro-batch (-ub) 512, F16 KV cache, context (-c) as shown; “Fits” is judged with llama-server’s default 4 parallel sequences (-np auto, unified KV cache) and “Doesn’t fit” with 1 sequence; idle GPU with no other programs using its memory.
• ROCm on Linux (AMD): llama.cpp, ROCm back end on Linux (AMD discrete GPU), all layers on the GPU, Flash Attention on, micro-batch (-ub) 512, F16 KV cache, context (-c) as shown; “Fits” is judged with llama-server’s default 4 parallel sequences (-np auto, unified KV cache) and “Doesn’t fit” with 1 sequence; idle GPU with no other programs using its memory.

The speed ceiling is memory bandwidth divided by the bytes read per generated token. It is a theoretical upper bound; public llama.cpp benchmarks typically reach about half to four-fifths of it, and small models and mixture-of-experts models often less. Public benchmarks

Original weights

The model’s original weight files (safetensors, counted as described in the methodology) total 65.4 GiB. They are listed for reference only; every estimate on this page is for the GGUF files above, run with llama.cpp. Hcompany/Holo4-35B-A3B · Methodology
