⚠️ Cortex is currently in Development: Expect breaking changes and bugs!
Cortex is an OpenAI-compatible AI engine that developers can use to build LLM apps. It is packaged with a Docker-inspired command-line interface and client libraries. It can be used as a standalone server or imported as a library.
Cortex supports the following engines:
cortex.llamacpp:cortex.llamacpplibrary is a C++ inference tool that can be dynamically loaded by any server at runtime. We use this engine to support GGUF inference with GGUF models. Thellama.cppis optimized for performance on both CPU and GPU.cortex.onnxRepository:cortex.onnxis a C++ inference library for Windows that leveragesonnxruntime-genaiand uses DirectML to provide GPU acceleration across a wide range of hardware and drivers, including AMD, Intel, NVIDIA, and Qualcomm GPUs.cortex.tensorrt-llm:cortex.tensorrt-llmis a C++ inference library designed for NVIDIA GPUs. It incorporates NVIDIA’s TensorRT-LLM for GPU-accelerated inference.
