How much VRAM do you need to run Kimi K2.6 (1T)?
With an estimated 1000B parameters, Kimi K2.6 (1T) needs roughly 1118 GB of VRAM in 8-bit (INT8), 559 GB in 4-bit, and 2235 GB in FP16, including a 20% overhead for activations and KV cache.
Which GPUs can run Kimi K2.6 (1T)?
At 8-bit quantization, the most cost-effective option is 6x AMD Instinct MI300X (1152 GB combined VRAM, around $36.00/hour on-demand). Higher-end cards like the NVIDIA B200 or AMD MI355X reduce the GPU count needed.
Can Kimi K2.6 (1T) run on a single GPU?
No. Even in 4-bit, Kimi K2.6 (1T) exceeds the memory of any single current GPU, so a multi-GPU cluster is required.
How much does it cost to serve Kimi K2.6 (1T) in the cloud?
Renting 6x Instinct MI300X costs on the order of $36.00/hour, i.e. about $26,280/month running 24/7. Actual prices vary by provider and commitment; spot and reserved capacity can be significantly cheaper.
