MiMo-V2.5 VRAM Requirements

Xiaomi, China · Released April 27, 2026

MiMo-V2.5 has 310.8B parameters (17B active per token). In BF16 its weights alone take 577 GiB; quantized to 4-bit, about 174 GiB. Each 32K-token request adds 0.73 GiB of KV cache. Cheapest way to run it today: 4 × RTX 6000 Ada (48 GB) at $2.16 per hour.

How many GPUs to run MiMo-V2.5

Fewest GPUs that fit the weights plus one 8K-token request. Data-center GPUs use vLLM (90% of memory usable), the others llama.cpp. Several GPUs split the model with tensor or pipeline parallelism.

8-bit: FP8 with vLLM (INT8 on GPUs without FP8), Q8_0 with llama.cpp. 4-bit: AWQ / GPTQ with vLLM, Q4_K_M with llama.cpp, both counted at the Q4_K_M size. —: the official FP8 weights do not run there: llama.cpp needs a GGUF version, and vLLM needs a GPU with FP8 support.

For each GPU: the fewest cards that fit MiMo-V2.5 with one 8K-token request, the most faithful weight format at that count, and the cheapest on-demand price (2026-10-11).

KV cache: how memory grows with context

Architecture: 48 layers · 9 full attention (4 KV × 192, values 128) · 39 sliding-window layers (128 tokens, 8 KV × 192). Its KV cache is 10.3× smaller than if every layer used full attention, because most layers only keep a short window of recent tokens. Only 17B parameters are active per token, but all 311B must sit in memory: VRAM depends on the total, speed on the active part.

MiMo-V2.5 VRAM FAQ

How much VRAM does MiMo-V2.5 need?

In BF16 the weights alone take 577 GiB (620 GB). In FP8 that is 290 GiB, and about 174 GiB with 4-bit quantization (Q4_K_M); the official FP8 checkpoint is 292 GiB. Each request then adds KV cache: 0.20 GiB at 8K tokens and 0.73 GiB at 32K (BF16 cache).

Can MiMo-V2.5 run on a single RTX 4090 (24 GB)?

No. Even in 4-bit it needs 16 (several servers) RTX 4090s. In 4-bit it needs 3 H100 GPUs.

What is the cheapest way to run MiMo-V2.5?

On 2026-10-11, the cheapest on-demand setup is 4 × RTX 6000 Ada (48 GB) with Q4_K_M weights on Vast.ai, at $2.16 per hour (about $1,573.88 per month). Next: 6 × NVIDIA A100 40GB with 4-bit weights on Vast.ai, at $2.56 per hour. Sized for one 8K-token request; prices are checked every hour.

How many H100 GPUs does MiMo-V2.5 need?

With one request and an 8K-token context: 16 (several servers) in BF16, 5 in FP8 and 3 in 4-bit (vLLM, 90% of memory usable). Serving many users at once needs more memory for their KV caches: the calculator sizes that for you.
