How to Run Kimi K2.5 Locally β Hardware, Quantization, and Setup Guide
Kimi K2.5 is a 1-trillion-parameter MoE model with 32B active parameters per token. Running it locally requires serious hardware, but the MIT license means you can deploy it however you want.
Update (April 21, 2026): Kimi K2.6 uses the same architecture as K2.5, so this setup guide works for both. K2.6 adds native INT4 QAT quantization for faster inference. See our K2.6 local setup guide for K2.6-specific instructions.
Hardware requirements
| Precision | Memory needed | Hardware example |
|---|---|---|
| FP16 | ~2TB | 8x H100 cluster |
| INT8 | ~1TB | 4x H100 or 8x A100 |
| 4-bit | ~250-300GB | 4x A100 80GB |
The MoE architecture helps β only 32B parameters activate per token, so inference is faster than a 1T dense model. But you still need enough memory to hold all 1T parameters.
Option 1: vLLM on GPU server
pip install vllm
huggingface-cli download moonshotai/Kimi-K2.5 --local-dir ./kimi-k2.5
python -m vllm.entrypoints.openai.api_server \
--model ./kimi-k2.5 \
--tensor-parallel-size 4 \
--max-model-len 32768 \
--port 8000
Then connect your tools:
# With Aider
aider --model openai/kimi-k2.5 --openai-api-base http://localhost:8000/v1
# With Kimi CLI
export KIMI_API_BASE="http://localhost:8000/v1"
kimi
Option 2: Cloud GPU rental
| Provider | Setup | Cost/hour |
|---|---|---|
| Lambda Labs | 8x A100 | ~$10/hr |
| RunPod | 4x A100 | ~$6/hr |
| Vast.ai | 4x A100 | ~$4/hr |
For occasional use, renting is cheaper than buying. For daily use, the Kimi API at $0.60/1M tokens is more economical.
Option 3: Use smaller alternatives locally
If you donβt have enterprise hardware, these run on consumer GPUs and offer good quality:
| Model | VRAM needed | Quality vs K2.5 |
|---|---|---|
| Qwen 3.5 27B | 16GB | ~75% |
| Gemma 4 27B | 16GB | ~75% |
| Devstral Small 24B | 14GB | ~70% |
| Codestral 22B | 12GB | ~65% (autocomplete) |
The practical recommendation: use K2.5 via API ($0.60/1M) for complex tasks and a local 27B model for routine work. See our cheapest AI coding setup guide.
