310.8B parameters, published in F8_E4M3. View on Hugging Face
Set up MiMo-V2.5MiMo-V2.5 is published by XiaomiMiMo on Hugging Face, with 384,629 downloads and 412 likes to date. It's a MiMoV2ForCausalLM model built for text-generation, published natively in F8_E4M3.
VRAM required & cheapest live GPU fit
Required VRAM = weight size at each precision, plus a fixed overhead for KV-cache, activations, and fragmentation. Full formula and assumptions: methodology.
| Precision | Weight size | Required VRAM | Cheapest live fit | GPUs needed | Est. $/hr (full fit) |
|---|---|---|---|---|---|
| FP8 (native) | 289.4 GB | 347.3 GB | RTX 4090 | 8 | $3.88/hr |
| INT4 (quantized) | 144.7 GB | 173.7 GB | RTX A5000 | 8 | $1.41/hr |
A GPU is only matched to a row if its hardware supports that precision, and the primary recommendation is always a single-GPU fit when one exists.
INT4 requires a quantized checkpoint actually published for this model, check its Hugging Face page before relying on this row.
Cheapest way to run MiMo-V2.5 at its published (F8_E4M3) precision: 8× RTX 4090, at $0.485/hr per GPU ($3.88/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
MiMo-V2.5: common questions
Can MiMo-V2.5 run on a single GPU?
No. At FP8 (native) it needs 347.3 GB of VRAM, more than a single 32 GB desktop card holds. The cheapest capable card in the live feed is a 48.0 GB RTX 4090, and it takes 8 of them.
Is MiMo-V2.5 already quantized?
Yes. It is published in FP8, one byte per parameter, so the 347.3 GB figure is already a quantized footprint rather than a full-precision one. Only INT4 goes below it, at 173.7 GB. A GPU without FP8 tensor cores cannot run it as published, which is why cards here are matched on precision support and not on VRAM alone.
How many GPUs do I need to run MiMo-V2.5?
8 at FP8 (native). It needs 347.3 GB of VRAM and the cheapest capable live offer is a 48.0 GB RTX 4090, so 8 of them come to $3.88/hr in total.
Does quantizing MiMo-V2.5 lower the GPU bill?
Yes. At FP8 (native) the cheapest live fit is 8 RTX 4090 cards at $3.88/hr. At INT4 (quantized) it drops to 8 RTX A5000 cards at $1.41/hr, provided a quantized checkpoint exists for it.
