   I tried this out and it looks like the issue is that dtype has to be specified when creating the `decl_buffer` for specialization. The default dtype would become float32 and the const version directly specified float16.
   
   Something like this
   ```python
   gemm_sp = gemm.specialize(
          {
               data: tvm.tir.decl_buffer((4096, 4096), dtype="float16"), weight: tvm.tir.decl_buffer((4096, 4096), dtype="float16"),
           }
       )
   ```
   However the printed IR for the specialized version is misleading as it shows the dtype as "float16", which I understand is why this issue was created, so that probably has to be fixed.
