FAISS added native Metal GPU backend support for Apple Silicon, starting with IndexFlat, enabling faster similarity search on M-series Macs without requiring CUDA or ROCm.
Native GPU acceleration via Metal for Apple Silicon devices, specifically enabling IndexFlat to run on M-series GPUs.
Developers using macOS with Apple Silicon can now run FAISS similarity search on GPU without relying on CUDA or ROCm drivers — reducing setup complexity and unlocking performance gains for local inference workloads. Operators deploying FAISS on M1/M2/M3 Macs will see lower latency and better throughput for vector search tasks. Watch for stability in multi-threaded or mixed-CPU/GPU scenarios and ensure compatibility with existing code that assumes CUDA backend.
