+# LocalAI Backend Architecture
+
+This directory contains the core backend infrastructure for LocalAI, including the gRPC protocol definition, multi-language Dockerfiles, and language-specific backend implementations.
+
+## Overview
+
+LocalAI uses a unified gRPC-based architecture that allows different programming languages to implement AI backends while maintaining consistent interfaces and capabilities. The backend system supports multiple hardware acceleration targets and provides a standardized way to integrate various AI models and frameworks.
+
+## Architecture Components
+
+### 1. Protocol Definition (`backend.proto`)
+
+The `backend.proto` file defines the gRPC service interface that all backends must implement. This ensures consistency across different language implementations and provides a contract for communication between LocalAI core and backend services.
+
+#### Core Services
+
+- **Text Generation**: `Predict`, `PredictStream` for LLM inference
+- **Embeddings**: `Embedding` for text vectorization
+- **Image Generation**: `GenerateImage` for stable diffusion and image models
+- **Audio Processing**: `AudioTranscription`, `TTS`, `SoundGeneration`
+- **Video Generation**: `GenerateVideo` for video synthesis
+- **Object Detection**: `Detect` for computer vision tasks
+- **Vector Storage**: `StoresSet`, `StoresGet`, `StoresFind` for RAG operations
+- **Reranking**: `Rerank` for document relevance scoring
+- **Voice Activity Detection**: `VAD` for audio segmentation
+
+#### Key Message Types
+
+- **`PredictOptions`**: Comprehensive configuration for text generation
+- **`ModelOptions`**: Model loading and configuration parameters
+- **`Result`**: Standardized response format
+- **`StatusResponse`**: Backend health and memory usage information
+
+### 2. Multi-Language Dockerfiles
+
+The backend system provides language-specific Dockerfiles that handle the build environment and dependencies for different programming languages:
+
+- `Dockerfile.python`
+- `Dockerfile.golang`
+- `Dockerfile.llama-cpp`
+
+### 3. Language-Specific Implementations
+
+#### Python Backends (`python/`)
+- **transformers**: Hugging Face Transformers framework
+- **vllm**: High-performance LLM inference
+- **mlx**: Apple Silicon optimization
+- **diffusers**: Stable Diffusion models
+- **Audio**: bark, coqui, faster-whisper, kitten-tts
+- **Vision**: mlx-vlm, rfdetr
+- **Specialized**: rerankers, chatterbox, kokoro
+
+#### Go Backends (`go/`)
+- **whisper**: OpenAI Whisper speech recognition in Go with GGML cpp backend (whisper.cpp)
+- **stablediffusion-ggml**: Stable Diffusion in Go with GGML Cpp backend
+- **huggingface**: Hugging Face model integration
+- **piper**: Text-to-speech synthesis Golang with C bindings using rhaspy/piper
+- **bark-cpp**: Bark TTS models Golang with Cpp bindings
+- **local-store**: Vector storage backend
+
+#### C++ Backends (`cpp/`)
+- **llama-cpp**: Llama.cpp integration
+- **grpc**: GRPC utilities and helpers
+
+## Hardware Acceleration Support
+
+### CUDA (NVIDIA)
+- **Versions**: CUDA 11.x, 12.x
+- **Features**: cuBLAS, cuDNN, TensorRT optimization
+- **Targets**: x86_64, ARM64 (Jetson)
+
+### ROCm (AMD)
+- **Features**: HIP, rocBLAS, MIOpen
+- **Targets**: AMD GPUs with ROCm support
+
+### Intel
+- **Features**: oneAPI, Intel Extension for PyTorch
+- **Targets**: Intel GPUs, XPUs, CPUs
+
+### Vulkan
+- **Features**: Cross-platform GPU acceleration
+- **Targets**: Windows, Linux, Android, macOS
+
+### Apple Silicon
+- **Features**: MLX framework, Metal Performance Shaders
+- **Targets**: M1/M2/M3 Macs
+
+## Backend Registry (`index.yaml`)
+
+The `index.yaml` file serves as a central registry for all available backends, providing:
+
+- **Metadata**: Name, description, license, icons
+- **Capabilities**: Hardware targets and optimization profiles
+- **Tags**: Categorization for discovery
+- **URLs**: Source code and documentation links
+
+## Building Backends
+
+### Prerequisites
+- Docker with multi-architecture support
+- Appropriate hardware drivers (CUDA, ROCm, etc.)
+- Build tools (make, cmake, compilers)
+
+### Build Commands
+
+Example of build commands with Docker
+
+```bash
+# Build Python backend
+docker build -f backend/Dockerfile.python \
+  --build-arg BACKEND=transformers \
+  --build-arg BUILD_TYPE=cublas12 \
+  --build-arg CUDA_MAJOR_VERSION=12 \
+  --build-arg CUDA_MINOR_VERSION=0 \
+  -t localai-backend-transformers .
+
+# Build Go backend
+docker build -f backend/Dockerfile.golang \
+  --build-arg BACKEND=whisper \
+  --build-arg BUILD_TYPE=cpu \
+  -t localai-backend-whisper .
+
+# Build C++ backend
+docker build -f backend/Dockerfile.llama-cpp \
+  --build-arg BACKEND=llama-cpp \
+  --build-arg BUILD_TYPE=cublas12 \
+  -t localai-backend-llama-cpp .
+```
+
+For ARM64/Mac builds, docker can't be used, and the makefile in the respective backend has to be used.
+
+### Build Types
+
+- **`cpu`**: CPU-only optimization
+- **`cublas11`**: CUDA 11.x with cuBLAS
+- **`cublas12`**: CUDA 12.x with cuBLAS
+- **`hipblas`**: ROCm with rocBLAS
+- **`intel`**: Intel oneAPI optimization
+- **`vulkan`**: Vulkan-based acceleration
+- **`metal`**: Apple Metal optimization
+
+## Backend Development
+
+### Creating a New Backend
+
+1. **Choose Language**: Select Python, Go, or C++ based on requirements
+2. **Implement Interface**: Implement the gRPC service defined in `backend.proto`
+3. **Add Dependencies**: Create appropriate requirements files
+4. **Configure Build**: Set up Dockerfile and build scripts
+5. **Register Backend**: Add entry to `index.yaml`
+6. **Test Integration**: Verify gRPC communication and functionality
+
+### Backend Structure
+
+```
+backend-name/
+├── backend.py/go/cpp    # Main implementation
+├── requirements.txt      # Dependencies
+├── Dockerfile           # Build configuration
+├── install.sh           # Installation script
+├── run.sh              # Execution script
+├── test.sh             # Test script
+└── README.md           # Backend documentation
+```
+
+### Required gRPC Methods
+
+At minimum, backends must implement:
+- `Health()` - Service health check
+- `LoadModel()` - Model loading and initialization
+- `Predict()` - Main inference endpoint
+- `Status()` - Backend status and metrics
+
+## Integration with LocalAI Core
+
+Backends communicate with LocalAI core through gRPC:
+
+1. **Service Discovery**: Core discovers available backends
+2. **Model Loading**: Core requests model loading via `LoadModel`
+3. **Inference**: Core sends requests via `Predict` or specialized endpoints
+4. **Streaming**: Core handles streaming responses for real-time generation

-# Common commands about conda environment
+# Python Backends for LocalAI
 
-## Create a new empty conda environment
+This directory contains Python-based AI backends for LocalAI, providing support for various AI models and hardware acceleration targets.
 
-```
+## Overview
-conda create --name <env-name> python=<your version> -y
 
-conda create --name autogptq python=3.11 -y
+The Python backends use a unified build system based on `libbackend.sh` that provides:
+- **Automatic virtual environment management** with support for both `uv` and `pip`
+- **Hardware-specific dependency installation** (CPU, CUDA, Intel, MLX, etc.)
+- **Portable Python support** for standalone deployments
+- **Consistent backend execution** across different environments
+
+## Available Backends
+
+### Core AI Models
+- **transformers** - Hugging Face Transformers framework (PyTorch-based)
+- **vllm** - High-performance LLM inference engine
+- **mlx** - Apple Silicon optimized ML framework
+- **exllama2** - ExLlama2 quantized models
+
+### Audio & Speech
+- **bark** - Text-to-speech synthesis
+- **coqui** - Coqui TTS models
+- **faster-whisper** - Fast Whisper speech recognition
+- **kitten-tts** - Lightweight TTS
+- **mlx-audio** - Apple Silicon audio processing
+- **chatterbox** - TTS model
+- **kokoro** - TTS models
+
+### Computer Vision
+- **diffusers** - Stable Diffusion and image generation
+- **mlx-vlm** - Vision-language models for Apple Silicon
+- **rfdetr** - Object detection models
+
+### Specialized
+
+- **rerankers** - Text reranking models
+
+## Quick Start
+
+### Prerequisites
+- Python 3.10+ (default: 3.10.18)
+- `uv` package manager (recommended) or `pip`
+- Appropriate hardware drivers for your target (CUDA, Intel, etc.)
+
+### Installation
+
+Each backend can be installed individually:
+
+```bash
+# Navigate to a specific backend
+cd backend/python/transformers
+
+# Install dependencies
+make transformers
+# or
+bash install.sh
+
+# Run the backend
+make run
+# or
+bash run.sh
 ```
 
-## To activate the environment
+### Using the Unified Build System
 
-As of conda 4.4
+The `libbackend.sh` script provides consistent commands across all backends:
-```
+
-conda activate autogptq
+```bash
+# Source the library in your backend script
+source $(dirname $0)/../common/libbackend.sh
+
+# Install requirements (automatically handles hardware detection)
+installRequirements
+
+# Start the backend server
+startBackend $@
+
+# Run tests
+runUnittests
 ```
 
-The conda version older than 4.4
+## Hardware Targets
 
-```
+The build system automatically detects and configures for different hardware:
-source activate autogptq
+
+- **CPU** - Standard CPU-only builds
+- **CUDA** - NVIDIA GPU acceleration (supports CUDA 11/12)
+- **Intel** - Intel XPU/GPU optimization
+- **MLX** - Apple Silicon (M1/M2/M3) optimization
+- **HIP** - AMD GPU acceleration
+
+### Target-Specific Requirements
+
+Backends can specify hardware-specific dependencies:
+- `requirements.txt` - Base requirements
+- `requirements-cpu.txt` - CPU-specific packages
+- `requirements-cublas11.txt` - CUDA 11 packages
+- `requirements-cublas12.txt` - CUDA 12 packages
+- `requirements-intel.txt` - Intel-optimized packages
+- `requirements-mps.txt` - Apple Silicon packages
+
+## Configuration Options
+
+### Environment Variables
+
+- `PYTHON_VERSION` - Python version (default: 3.10)
+- `PYTHON_PATCH` - Python patch version (default: 18)
+- `BUILD_TYPE` - Force specific build target
+- `USE_PIP` - Use pip instead of uv (default: false)
+- `PORTABLE_PYTHON` - Enable portable Python builds
+- `LIMIT_TARGETS` - Restrict backend to specific targets
+
+### Example: CUDA 12 Only Backend
+
+```bash
+# In your backend script
+LIMIT_TARGETS="cublas12"
+source $(dirname $0)/../common/libbackend.sh
 ```
 
-## Install the packages to your environment
+### Example: Intel-Optimized Backend
 
-Sometimes you need to install the packages from the conda-forge channel
+```bash
-
+# In your backend script
-By using `conda`
+LIMIT_TARGETS="intel"
-```
+source $(dirname $0)/../common/libbackend.sh
-conda install <your-package-name>
-
-conda install -c conda-forge <your package-name>
 ```
 
-Or by using `pip`
+## Development
+
+### Adding a New Backend
+
+1. Create a new directory in `backend/python/`
+2. Copy the template structure from `common/template/`
+3. Implement your `backend.py` with the required gRPC interface
+4. Add appropriate requirements files for your target hardware
+5. Use `libbackend.sh` for consistent build and execution
+
+### Testing
+
+```bash
+# Run backend tests
+make test
+# or
+bash test.sh
 ```
-pip install <your-package-name>
+
+### Building
+
+```bash
+# Install dependencies
+make <backend-name>
+
+# Clean build artifacts
+make clean
 ```
+
+## Architecture
+
+Each backend follows a consistent structure:
+```
+backend-name/
+├── backend.py          # Main backend implementation
+├── requirements.txt    # Base dependencies
+├── requirements-*.txt  # Hardware-specific dependencies
+├── install.sh         # Installation script
+├── run.sh            # Execution script
+├── test.sh           # Test script
+├── Makefile          # Build targets
+└── test.py           # Unit tests
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Missing dependencies**: Ensure all requirements files are properly configured
+2. **Hardware detection**: Check that `BUILD_TYPE` matches your system
+3. **Python version**: Verify Python 3.10+ is available
+4. **Virtual environment**: Use `ensureVenv` to create/activate environments
+
+## Contributing
+
+When adding new backends or modifying existing ones:
+1. Follow the established directory structure
+2. Use `libbackend.sh` for consistent behavior
+3. Include appropriate requirements files for all target hardware
+4. Add comprehensive tests
+5. Update this README if adding new backend types
