**A2Genesis** is an independent software studio in Bochum, Germany. We build custom applications and run language models on our own hardware.

Here we publish quantized checkpoints of open-weight models. The quantization recipe, the calibration data and the serving configuration are documented in every model card, so a result can be reproduced rather than taken on trust.

### Models
- **[Qwen3.8-27B-NVFP4](https://huggingface.co/a2genesis/Qwen3.8-27B-NVFP4)** — NVFP4 (W4A16) quantization of `Qwen/Qwen3.8-27B`, produced with NVIDIA TensorRT Model Optimizer 0.45. About 21 GB instead of 55 GB, so it fits on a single GPU. Apache 2.0.
### Focus
- Post-training quantization (NVFP4, FP8, NVIDIA ModelOpt)
- Self-hosted inference with vLLM and SGLang
- AI-native application development
