Kimi K2.5 1T GPU requirements

What it takes to run Kimi K2.5 1T (MoE) locally: memory by quantization, the smallest GPU that fits, and the managed alternative.

No single GPU fits this configuration. Shard across devices, quantize harder, or run it managed.

How it works

1
Check the table
Kimi K2.5 1T at 8K context across FP16, 8-bit, and 4-bit, with the smallest single device that fits each.
2
Tune the calculator
Longer context grows the KV cache. The slider shows exactly how much memory that adds.
3
Decide how to run it
MoE weights must fit in memory in full, so serving this locally means a multi-GPU fleet, not one card.

Common questions

How much VRAM does Kimi K2.5 1T need?

At 8K context: roughly 2205 GB at FP16, 1102 GB at 8-bit, and 606 GB at 4-bit, including KV cache and runtime overhead. Longer context adds memory linearly.

Can a single GPU run Kimi K2.5 1T?

Not at practical quantizations: even 4-bit needs about 606 GB, beyond any single device here. Sharding across a fleet or managed serving are the options.

Why does Kimi K2.5 1T need so much memory as a MoE model?

Only some experts activate per token, which sets speed, but all 1.0 trillion parameters must sit in memory. MoE trades memory for throughput.

What license is Kimi K2.5 1T under?

Modified MIT. Permissive: run it, fine-tune it, and own the result.

Is there an alternative to buying GPUs for Kimi K2.5 1T?

Yes: managed inference. Allocate serves Kimi K2.5 1T token-metered inside your own boundary, and if you fine-tune it on your data, the weights belong to you. Idle time costs nothing.
