KTransformers - Flexible LLM Inference Framework

1 min read Original article ↗

Low-VRAM, Full-Precision Inference

KTransformers uses CPU/GPU heterogeneous computing, leveraging CPU memory and compute
to deploy top-tier 100B+ parameter models locally with just a single RTX 5090 (32GB VRAM).

Low-VRAM Full-Parameter Fine-Tuning

Fine-tune 100B+ parameter models with full parameters on consumer GPUs — no expensive multi-GPU clusters needed.

Start InferenceView on GitHub

Built for developers who want to run large models on accessible hardware without sacrificing performance.

Optimize inference using CPU, GPU, and other accelerators together. Run large models on consumer hardware.

No quantization needed. Preserve the original model precision to ensure uncompromised inference quality.

Full-Stack Inference & Fine-Tuning

A complete local deployment toolchain from inference to fine-tuning, all-in-one for your development needs.

Supports DeepSeek, Kimi, GLM, Qwen, MiniMax and more mainstream large models for diverse use cases.
