Introduction

Learn what Neuron is and what you can do with it.

What is Neuron

Neuron is a PHP framework for developing agentic applications. By handling the heavy lifting of orchestration, data loading, and debugging, Neuron clears the path for you to focus on the creative soul of your project. From the first line of code to a fully orchestrated multi-agent system, you have the freedom to build AI entities that think and act exactly how you envision them.

We provide tools for the entire agentic application development lifecycle, from LLM interfaces, to data loading, to multi-agent orchestration, to monitoring and debugging. In addition, we provide tutorials and other educational content to help you get started using AI Agents in your projects.

Neuron architecture

Getting Started In 3 Steps

1) Install Neuron in you project:

composer require neuron-core/neuron-ai

2) Create an agent extending the Agent class:

namespace App\Neuron;

use NeuronAI\Agent\Agent;
use NeuronAI\Providers\Anthropic\Anthropic;

class MyAgent extends Agent
{
    protected function provider(): AIProviderInterface
    {
        // return an AI provider (Anthropic, OpenAI, Ollama, Gemini, etc.)
        return new Anthropic(
            key: 'ANTHROPIC_API_KEY',
            model: 'ANTHROPIC_MODEL',
        );
    }
}

3) Talk with the agent:

use NeuronAI\Chat\Messages\UserMessage;

$message = MyAgent::make()
    ->chat(new UserMessage("Hi, who are you?"))
    ->getMessage();

echo $message->getContent();
// I'm a friendly AI Agent built with Neuron AI framework, how can I help you today?

Demo with Laravel

Neuron offers a well defined encapsulation pattern, allowing you to work on your AI components in a dedicated namespace. You can enjoy the exact same experience of the other ecosystem packages you already love, like Filament, Nova, Horizon, etc.

Watch the demo

Official Laravel Package

Demo with Symfony

All Neuron components belong to its own interface, so you can easily define dependencies and automate objects creation using the Symfony service container. Watch how it works in a real project.

Support For Multiple Providers

Neuron uses a common interface for large language models (AIProviderInterface) as well as for the other components, such as embedding, vector stores, toolkits, etc. The modular architecture allows you to swap components as needed, whether you're changing LLM provider, adjusting memory backends, or scaling across multiple servers.

Here are a couple of examples:

Anthropic

namespace App\Neuron;

use NeuronAI\Agent\Agent;
use NeuronAI\Chat\Messages\UserMessage;
use NeuronAI\Providers\AIProviderInterface;
use NeuronAI\Providers\Anthropic\Anthropic;

class MyAgent extends Agent
{
    protected function provider(): AIProviderInterface
    {
        return new Anthropic(
            key: 'ANTHROPIC_API_KEY',
            model: 'ANTHROPIC_MODEL',
        );
    }
}

$message = MyAgent::make()
    ->chat(new UserMessage("Hi!"))
    ->getMessage();

echo $message->getContent();
// Hi, how can I help you today?

Ollama

namespace App\Neuron;

use NeuronAI\Agent\Agent;
use NeuronAI\Chat\Messages\UserMessage;
use NeuronAI\Providers\AIProviderInterface;
use NeuronAI\Providers\Ollama\Ollama;

class MyAgent extends Agent
{
    protected function provider(): AIProviderInterface
    {
        return new Ollama(
            url: 'OLLAMA_URL',
            model: 'OLLAMA_MODEL',
        );
    }
}

$message = MyAgent::make()
    ->chat(new UserMessage("Hi!"))
    ->getMessage();

echo $message->getContent();
// Hi, how can I help you today?

OpenAI

namespace App\Neuron;

use NeuronAI\Agent\Agent;
use NeuronAI\Chat\Messages\UserMessage;
use NeuronAI\Providers\AIProviderInterface;
use NeuronAI\Providers\OpenAI\OpenAI;

class MyAgent extends Agent
{
    protected function provider(): AIProviderInterface
    {
        return new OpenAI(
            key: 'OPENAI_API_KEY',
            model: 'OPENAI_MODEL',
        );
    }
}

$message = MyAgent::make()
    ->chat(new UserMessage("Hi!"))
    ->getMessage();

echo $message->getContent();
// Hi, how can I help you today?

Gemini

namespace App\Neuron;

use NeuronAI\Agent\Agent;
use NeuronAI\Chat\Messages\UserMessage;
use NeuronAI\Providers\AIProviderInterface;
use NeuronAI\Providers\Gemini\Gemini;

class MyAgent extends Agent
{
    protected function provider(): AIProviderInterface
    {
        return new Gemini(
            key: 'GEMINI_API_KEY',
            model: 'GEMINI_MODEL',
        );
    }
}

$message = MyAgent::make()
    ->chat(new UserMessage("Hi!"))
    ->getMessage();

echo $message->getContent();
// Hi, how can I help you today?

Mistral

namespace App\Neuron;

use NeuronAI\Agent\Agent;
use NeuronAI\Chat\Messages\UserMessage;
use NeuronAI\Providers\AIProviderInterface;
use NeuronAI\Providers\Gemini\Mistral;

class MyAgent extends Agent
{
    protected function provider(): AIProviderInterface
    {
        return new Mistral(
            key: 'MISTRAL_API_KEY',
            model: 'MISTRAL_MODEL',
        );
    }
}

$message = MyAgent::make()
    ->chat(new UserMessage("Hi!"))
    ->getMessage();

echo $message->getContent();
// Hi, how can I help you today?

Why Neuron

Your next application will be agentic. A growing share of new software is no longer a web application with AI features added along the way, but an application born agentic, where the agent is the architecture itself, driving how the system reasons, acts, and talks to the user interface. Building this kind of application requires a specific set of foundations: event-driven workflows with checkpointing, human-in-the-loop, interruption, multi-agent orchestration, streaming, and agentic UI protocols like AG-UI and the Vercel AI SDK protocol, MCP, and asynchronous execution.

In the PHP ecosystem, this set of foundations exists in one place. Each one is a chapter of this documentation: Workflow, Human in the loop, Streaming & UI protocols, MCP, Async. You can compare it with any other option available to a PHP developer, and the comparison is the answer.

There is also no second framework waiting for you when the project grows. The same Workflow that runs your first agent in the getting started guide runs a multi-agent system with state, loops, and human approvals in production. What you learn on day one is what you ship in future projects.

A Vertical & Independent Ecosystem

Neuron is also the only vertical ecosystem for agentic applications development in PHP. Around the framework there is a registry of extensions, tools, and technologies designed specifically for agentic-native applications, and a growing number of companies building on the same architecture instead of assembling their own from scattered parts.

For a software house, this is a place to be recognized as a specialist rather than one more team claiming AI experience. For a company that needs an agentic foundation it can commit to for years, it means standardizing on an architecture whose whole direction is this space, not a general-purpose library where agents are a side feature.

E-Book - "Start With AI Agents In PHP"

The gap between modern agentic technologies and traditional PHP development has been widening in recent years. While Python developers enjoy a wealth of libraries and frameworks to create AI Agents, PHP developers have often been left wondering how they can participate in this technological revolution without completely retooling their skillsets or rebuilding their applications from scratch.

Neuron changes all that.

This book serves as both an introduction to AI Agents concepts for developers and a comprehensive guide to Neuron framework.
