FP4 is a 4-bit floating point format that represents a significant reduction from traditional 32-bit and 64-bit floating point standards. This compact format enables more efficient storage and computation in resource-constrained environments like edge devices and AI accelerators.
FP4 is a 4-bit floating point format that uses 1 sign bit, 2 exponent bits, and 1 mantissa bit. It has limited precision and dynamic range, making it suitable for specialized applications like AI inference where memory bandwidth is constrained.
USearch introduces FP8 (8-bit floating point) support for vector search and KV-caching, enabling more efficient memory usage and faster computations. The implementation allows for reduced storage requirements while maintaining search accuracy through quantization techniques.
