Greek Seer [1]
Seer,
an UCI compliant open source chess engine by Connor McMonigle, written in C++,
licensed under the GNU GPL and first released in October 2020.
Seer uses a custom NNUE implementation based on 32-bit float weights with training code written in PyTorch and inference code relying on OpenMP SIMD for auto vectorization [2].
Due to PEXT Bitboards, Seer requires BMI2 for a reasonable performance, as well as either SSE, AVX, AVX2 or AVX-512 to calculate the NNUE.
