feagi-core 2.1.1

Core SDK for building FEAGI agents, controlling the neural engine, and creating marketplace packages (without Brain Visualizer)

FEAGI Python SDK

Build AI agents that learn like biological brains

---

Installation Options

Full Experience (Recommended for Development):

pip install feagi

Includes Brain Visualizer for real-time 3D neural activity visualization (~196MB)

Slim/Core (Recommended for Production):

pip install feagi-core

SDK only without Brain Visualizer - perfect for containers, CI/CD, and inference (~5MB)

Note: Both packages use identical imports (from feagi import ...)

What is FEAGI?

FEAGI (Framework for Evolutionary Artificial General Intelligence) is a biologically inspired, modular neural execution engine designed for embodied AI and robotics. FEAGI enables spiking-neural-circuit-driven perception, cognition, and control across simulated and physical embodiments, with a strong emphasis on real-time interaction, modularity, and cross-platform deployment.

FEAGI serves as the core neural runtime behind Neurorobotics Studio, powering a growing ecosystem of reusable neural components ("brains"), tools, and integrations for robotics and physical AI.

The FEAGI Python SDK

The FEAGI Python SDK provides the tools you need to:

• Connect robots and devices to FEAGI's neural network
• Build learning agents for robots, simulators, and games
• Visualize neural activity in real-time with Brain Visualizer
• Control and manage FEAGI from Python code
• Interface with diverse embodiments through standardized communication protocols

---

Key Concepts

• Neuromorphic by Design – FEAGI is built as a neuromorphic framework inspired by biological neural computation. While it currently runs on conventional CPUs and GPUs, native support for neuromorphic hardware is a near-term roadmap item, enabling direct execution on event-driven, spike-based accelerators as they mature.

• Embodied Intelligence First – FEAGI is designed to control bodies (robots, agents, simulations), not just process static data.

• Spiking Neural Networks (SNNs) – Uses event-driven neuron firing rather than frame-based inference.

• Modular Neural Architecture – Neural circuits can be composed like building blocks (Lego-like micro-circuits).

• Real-Time Closed Loop – Continuous perception → cognition → action loop.

• Cross-Simulator & Hardware Support – One brain, many bodies.

---

Core Capabilities

Neural Processing

• Large-scale spiking neural networks
• Sparse connectivity and event-driven execution
• Fire Candidate Lists (FCL) and optimized firing pipelines
• Supports long-term and short-term memory constructs

Modular Brain Design

• Pre-packaged micro-circuits (sensory, motor, cognitive)
• Community-developed and shareable neural components
• Easy composition into larger functional brains

Embodiment Integration

FEAGI supports diverse embodiments through its flexible communication architecture:

• Physical Robots – AMRs, manipulators, service robots, drones
• Virtual Simulations – Webots, Gazebo, Unity, custom simulators
• Game Engines – Real-time game AI and NPCs
• IoT Devices – Sensors, actuators, embedded systems
• Research Platforms – Custom experimental setups

See the embodiment-controllers repository for available integrations.

Performance & Portability

• CPU multiprocessing support
• GPU acceleration paths
• Designed for future support of:
  • Vulkan
  • WebGPU
  • WebAssembly (WASM)
• Sparse matrix and bit-packed data representations

## Example Use Cases

FEAGI runs as the **neural execution engine**, while adapters (built with this SDK) translate between FEAGI's neural signals and the embodiment's sensors and actuators.

---

## Example Use Cases

* Autonomous mobile robots (AMRs)
* Service robots (cleaning, logistics, inspection)
* Robotic manipulation and dexterous hands
* AI-driven simulation agents
* Research in biologically inspired AI
* Education and rapid prototyping of embodied intelligence
* Game AI that adapts to players
* Educational neuroscience simulations

## Quick Start

Get started with FEAGI in just 2 lines:

```bash
pip install "feagi[bv]"
feagi bv start

That's it! This installs FEAGI with Brain Visualizer, creates default configuration automatically, and launches the visualizer.

Note for zsh users (macOS default): Use quotes around "feagi[bv]" to avoid shell glob expansion errors.

For detailed installation options, configuration, and platform-specific notes, see DEPLOY.md.

Build Your First Agent

from feagi.agent import BaseAgent

class MyRobotAgent(BaseAgent):
    def initialize_hardware(self):
        # Connect to your robot/simulator
        pass
    
    def map_sensors(self, hw_data):
        # Send sensor data to FEAGI
        return {"camera": image_bytes}
    
    def map_motors(self, feagi_output):
        # Control motors from FEAGI commands
        return motor_commands

# Run it
agent = MyRobotAgent("my-robot")
await agent.connect()
await agent.run()

Advanced Usage

Configuration Management

Initialize FEAGI environment with default configuration:

feagi init

This creates:

• Configuration: ~/.feagi/config/feagi_configuration.toml
• Genomes directory: ~/Documents/FEAGI/Genomes/ (macOS/Windows) or ~/FEAGI/genomes/ (Linux)
• Connectomes directory: ~/Documents/FEAGI/Connectomes/ or ~/FEAGI/connectomes/
• Logs and cache directories

For complete configuration options and customization, see DEPLOY.md.

Optional Extras

Install additional features as needed:

# Video processing (OpenCV)
pip install "feagi[video]"

# Bluetooth support
pip install "feagi[bluetooth]"

# All extras
pip install "feagi[full]"

zsh users: Always use quotes around package names with brackets.

Direct PNS Communication

For low-level control over FEAGI communication:

from feagi.pns import FeagiAgentClient, AgentType

client = FeagiAgentClient("my-agent", AgentType.SENSORY)
client.configure(feagi_host="localhost", feagi_api_port=8000)
await client.connect()

# Send sensory data
await client.send_sensory_data({
    "camera": image_data,
    "lidar": distance_readings
})

# Receive motor commands
motor_data = await client.receive_motor_data()

Start FEAGI Engine from Python

from feagi.engine import FeagiEngine

engine = FeagiEngine()
engine.load_config()  # Uses default config
engine.load_genome("my_brain.json")  # Loads from genomes directory
engine.start()

Or from command line:

feagi start --config ~/.feagi/config/feagi_configuration.toml --genome my_brain.json

# New (feagi 2.x)
from feagi.pns import FeagiAgentClient

Breaking changes:

• Package renamed: feagi_connector → feagi
