| Feature | VASP 5.4.4 | VASP 6.4+ | | :--- | :--- | :--- | | Machine learning force fields | ❌ No (No ML_FF) | ✅ Yes | | HDF5 output | ❌ (Binary OUTCAR/CHGCAR) | ✅ (Optional but default) | | DFT-D4 dispersion | ✅ Yes (Stable) | ✅ (Improved) | | GPU support | ❌ (Requires separate version) | ✅ Native | | Complexity of compilation | Low (straightforward) | High (HDF5 dependencies) | | Post-processing tools | High (many legacy scripts) | Medium (breakage due to HDF5) |

For many research groups performing standard DFT (PBE, SCAN) with hybrid functionals (HSE06), version 5.4.4 is more than sufficient and significantly easier to maintain.
