Project mention: Adding 70-language translation to an image API without paying per word | dev.to | 2026-06-09
Runtime: CTranslate2 with int8 quantization. This is the key piece. It shrinks the model to ~1.3 GB and runs CPU inference fast. Do not run raw transformers on CPU for this.
-
xsimd
C++ wrappers for SIMD intrinsics and parallelized, optimized mathematical functions (SSE, AVX, AVX512, NEON, SVE, WebAssembly, VSX, RISC-V))
-
Simd
C++ image processing and machine learning library with using of SIMD: SSE, AVX, AVX-512, AMX for x86/x64, NEON, SVE for ARM, HVX for Hexagon (by ermig1979)
-
kfr
Fast, modern C++ DSP framework, FFT, Sample Rate Conversion, FIR/IIR/Biquad Filters (SSE, AVX, AVX-512, ARM NEON, RISC-V RVV)
Project mention: Show HN: KFR 7 – major update for C++ DSP library | news.ycombinator.com | 2025-11-17 -
DirectXMath
DirectXMath is an all inline SIMD C++ linear algebra library for use in games and graphics apps

-
MIPP
Portable wrapper for SIMD and vector instructions written in C++11. Compatible with NEON, SSE, AVX, AVX-512 and SVE (length specific).
-
Jsonifier
A few classes for extremely fast json parsing/serializing in modern C++. Possibly the fastest json parser in C++. Possibly the fastest json serializer in C++. (by RealTimeChris)
