Laguna S 2.1 INT4 is a quantized open-weight text model from poolside, running at INT4 precision which reduces memory footprint at the cost of some numerical fidelity compared to full-precision variants. It handles an unusually large context window of 262,144 tokens, making it capable of processing very long documents in a single pass. The INT4 quantization makes it more accessible for deployment on consumer or edge hardware.
