| 64 users, 8K context each | About 663 GB | About 266 GB |
Which GPUs can run Kimi K2.5 and MiniMax-M2.5
Smallest setup on each system, with 8K context per user. Green fits on one GPU or system, amber needs several in one server, grey needs more than one 8-GPU server.

Setups in amber or grey need several GPUs or servers working as one. Buying the GPUs is the easy part. Vanik Edge OS splits the model across them, keeps it running if a server fails and manages it all from one console. See how Edge OS clusters GPU servers
Which is faster?
On the same hardware, Kimi K2.5 should generate tokens about 6.6× faster for each user: it reads about 19 GB of weights per token (32B active at INT4) versus 126 GB for MiniMax-M2.5. Token generation is limited mostly by memory bandwidth, so fewer active bytes means faster replies. Real throughput also depends on batching, the inference engine and the GPU.
FROM SIZING TO RUNNING
Sizing the hardware is the easy part.

Can I run Kimi K2.5 locally?
Yes. At INT4 it needs about 626 GB of GPU memory for one user with 8K context, which fits on 8 × NVIDIA H100 NVL. A team of 16 needs about 635 GB: 8 × NVIDIA H100 NVL.
Can I run MiniMax-M2.5 locally?
Yes. At 4-bit it needs about 135 GB of GPU memory for one user with 8K context, which fits on 2 × NVIDIA H100 NVL. A team of 16 needs about 167 GB: 2 × NVIDIA H100 NVL.
Can I use Kimi K2.5 and MiniMax-M2.5 commercially?
Kimi K2.5 is released under Modified MIT. MiniMax-M2.5 is released under Modified MIT. Check each license before a commercial deployment.
How are these numbers calculated?
Memory figures come from our VRAM calculator method: weights at the lowest released precision, plus the KV cache for each user’s context, plus about 5 to 10% runtime overhead, keeping 10% of each GPU free. Where a developer does not publish the cache size we estimate it from the architecture. These are planning estimates, not benchmarks.
