v0.0.1

Core features of QuTLASS v0.0.1:

• MXFP4 microscaling support, with
• Weight and Activation quantization (W4A4)
• Online rotations: fused kernel for Hadamard tranforms, quantization, and scale computation.
  • Hadamard sizes matching the microscaling group sizes (i.e., 32 for MXFP4).
  • Compatible with any rotation matrix defined, as they are loaded in runtime.
• Multiple quantization schemes:
  • Quartet (i.e., Quest-like).
  • Abs-Max.
• Matmul kernels:
  • CUTLASS-backed MXFP4:MXFP4 kernel with block-scale reordering.
  • Prototype kernel for small batch sizes (no reordering required).
• Transformers Integration (PR #38696)
