Laguna-S-2.1-INT4 is a compressed, 4-bit quantized variant of Poolside's Laguna-S-2.1 Mixture-of-Experts language model. It uses compressed-tensors quantization to reduce model size and memory requirements while maintaining generation quality. The model is designed for text-generation tasks and can be loaded via the Hugging Face Transformers library with custom Laguna modeling code.
