Non-uniform GGUF quantizations produced with GSQ and RCO, with a vision projector for multimodal use. [](https://arxiv.org/abs/2604.18556) [](https://arxiv.org/abs/2605.00649) [](https://github.com/IST-DASLab/GSQ) [](https://github.com/IST-DASLab/RCO) [](https://github.com/IST-DASLab) [](#license) This repository provides GGUF quantizations of Qwen3.8-27B at four sizes, together with the model's vision projector (mmproj) for multimodal use. In contrast to uniform quantization, which applies a single quantization type to all weight tensors, each model here assigns a separate quantization type to every tensor. The assignment is obtained by a gradient-based search that allocates precision according to per-tensor sensitivity, subject to a total size budget. The resulting files are standard GGUF and run unmodified in llama.cpp, Ollama, and LM Studio. Both methods were developed at the Deep Algorithms and Systems Lab (DASLab), Institute of Science and Technology Austria. Files follow the convention -GSQ-RCO-.gguf, where the suffix names the quantization class; the table lists each file's true whole-file average bit-width. The mmproj file carries the vision encoder and…

Compatibility and lineage
Language coverage was not reported.
Reported base models: Qwen/Qwen3.8-27B
Parameter count is not a RAM/VRAM requirement. Check precision, quantization, context length and runtime compatibility in the model card; no hardware or API-cost claim is inferred here.
Use and evaluate
Check license terms and access requirements first. Review the model card’s documented loading instructions, evaluations and safety limitations. Benchmark scores are not imported by this directory, and popularity is not an accuracy ranking.
No model weights are downloaded or executed by AltAPIs. Never enable remote model code without reviewing it.
