Gaussian 16 Revision C.01 _verified_ Jun 2026

While Gaussian 16 originally introduced a massive library of functionals, Revision C.01 continues to tweak the implementation of newer methods.

: Corrected the route for Opt=(TS,ReCalcFC=N) and improved the GEDIIS optimization algorithm for better stability in floppy molecules .

Complete Active Space Self-Consistent Field (CASSCF) for multi-reference systems.

. The ability to leverage V100 GPUs and the improved parallel scaling can cut weeks off of long-term research projects. Furthermore, the enhanced

Revision C.01 left fingerprints beyond the technical. It altered how she saw problems. The patience bred by chasing a stubborn transition state changed how she listened to conversations, to the half-formed intuition of a student, to the slow bloom of an idea. There was a humility to it: software could reveal, but revelation required care. The program had corrected numerical biases in her own judgment; she had mistaken roughness for impossibility and clarity for triviality. Learning to read the output meant learning to read the world more slowly, with less confidence and more attention.

The following real-world benchmarks offer insights into the capabilities of Rev. C.01. While Gaussian 16 originally introduced a massive library
