4-bit floating point FP4
4-bit floating point isn't just smaller. It's how the next generation of inference happens at 1/4 the memory cost.

Why it matters
FP4 represents a critical compression technique for efficient model inference and deployment, directly impacting the feasibility and cost of running large language models at scale in production environments.
