Greptile Summary

This PR corrects five error messages in the #else stub block of cublaslt_grouped_gemm.cu that fire when the compile-time cuBLAS version is below 13.3. The old messages instructed users to "upgrade to CUDA 13.3", which is misleading because cuBLAS now follows its own independent semantic versioning — cuBLAS 13.3 is actually shipped with CUDA 13.2, not a hypothetical CUDA 13.3.

Confidence Score: 5/5

Safe to merge — pure error message correction with no logic or behavioral changes.

All changes are string literals inside compile-time fallback stubs. No logic, API, or behavior is altered. The updated wording is factually accurate per cuBLAS's independent versioning scheme.

No files require special attention.

Important Files Changed

Filename	Overview
transformer_engine/common/gemm/cublaslt_grouped_gemm.cu	5 error message strings updated in version-guard stubs to correctly reference cuBLAS 13.3 and its CUDA 13.2 shipping vehicle; no logic changes.
