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. More recently, Seer supports ARM NEON via sse2neon [3] to run on many Android devices [4].
