Simd.ai is a specialized platform built to accelerate SIMD code porting across architectures like SSE4.2, NEON, and VSX (more engines are coming). At its core is SIMD-ai-2506.1, a 24B-parameter LLM fine-tuned on high-quality, architecture-aligned data sourced from simd.info — a curated knowledge base of SIMD intrinsics.
Unlike generic models, it understands intrinsic-level mappings, prototypes, and low-level code semantics, and excels at translating, optimizing, and validating SIMD code across architectures with high accuracy and efficiency.
