Kimi K2.6 VRAM Requirements

Moonshot AI, China · Released April 14, 2026

Kimi K2.6 has 1026.9B parameters (32B active per token). In BF16 its weights alone take 1913 GiB; quantized to 4-bit, about 577 GiB. Each 32K-token request adds 2.14 GiB of KV cache. Cheapest way to run it today: 7 × RTX PRO 6000 Blackwell (96 GB) at $9.34 per hour.

VRAM by precision and context length

Weights plus the KV cache of one request (BF16 cache), in GiB. Add 1 to 3 GiB for the inference engine itself.

How many GPUs to run Kimi K2.6

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.

Cheapest way to run Kimi K2.6 today

For each GPU: the fewest cards that fit Kimi K2.6 with one 8K-token request, the most faithful weight format at that count, and the cheapest on-demand price (2026-10-10).

On-demand prices from RunPod, Vast.ai, Verda and Azure, checked every hour. Serving many users needs more KV cache, so more memory: size it in the calculator. Some links are affiliate links: StudioTV may earn a commission, at no extra cost to you.

KV cache: how memory grows with context

Architecture: MoE 384 experts · MLA (512 + 64 latent) on 61 layers · INT4 checkpoint (group size 32). Its cache stays compact because MLA stores one compressed latent per token and layer instead of full keys and values. Only 32B parameters are active per token, but all 1027B must sit in memory: VRAM depends on the total, speed on the active part.

Kimi K2.6 VRAM FAQ

How much VRAM does Kimi K2.6 need?

In BF16 the weights alone take 1913 GiB (2054 GB). In FP8 that is 959 GiB, and about 577 GiB with 4-bit quantization (Q4_K_M); the official INT4 checkpoint is 554 GiB. Each request then adds KV cache: 0.54 GiB at 8K tokens and 2.14 GiB at 32K (BF16 cache).

Can Kimi K2.6 run on a single RTX 4090 (24 GB)?

No. Even in 4-bit it needs 32 (several servers) RTX 4090s. In 4-bit it needs 16 (several servers) H100 GPUs.

What is the cheapest way to run Kimi K2.6?

On 2026-10-10, the cheapest on-demand setup is 7 × RTX PRO 6000 Blackwell (96 GB) with INT4 weights on Vast.ai, at $9.34 per hour (about $6,816.74 per month). Next: 4 × AMD MI300X (192 GB) with INT4 weights on RunPod, at $9.56 per hour. Sized for one 8K-token request; prices are checked every hour.

How many H100 GPUs does Kimi K2.6 need?

With one request and an 8K-token context: 32 (several servers) in BF16, 16 (several servers) in FP8 and 16 (several servers) 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.
