An 84-Format Numeric Catalog with Bit-Exact Conformance Vectors: A Vendor-Neutral Reference for FP8, BF16, MXFP4, and Microscaling Formats
Researchers have published a vendor-neutral catalog of 84 numeric formats used in machine learning hardware, including FP8, BF16, and MXFP4, with bit-exact conformance test vectors to enable consistent model porting across different accelerators. This addresses a critical gap where silent numerical divergences occur when moving ML models between vendors without a shared reference standard.
