A specialist that stays in its lane — this model takes in text and returns a relevance score, nothing more. It operates as a reranker, meaning it's designed to evaluate and order candidate passages or documents rather than generate prose. With a 4B parameter footprint and NVFP4 quantization, it trades some numerical precision for reduced memory overhead.

ParameterA learned value inside a neural network that the model adjusts during training to improve its predictions.Parameter FootprintThe total number of learnable weights in a model, which directly affects its memory requirements and computational cost — smaller footprints run faster on consumer devices.PrecisionThe level of numerical detail a model uses to represent its internal values; higher precision means more accurate calculations but requires more memory.QuantizationReducing a model's numerical precision (e.g., from 16-bit to 4-bit) to shrink memory usage and speed up inference.RerankerA model that takes an initial set of search results and reorders them by relevance, typically used to refine results from a faster but less accurate retrieval system.
