PHP: Neuron AI & Symfony AI
Recommended libraries and frameworks for integrating AI into PHP applications.
The PHP ecosystem has two main options depending on the project context:
| Neuron AI | Symfony AI | |
|---|---|---|
| Best for | Agents with tools, multi-provider, any modern PHP | Native integration in existing Symfony projects |
| Framework | Agnostic (Laravel, Symfony, vanilla PHP) | Symfony 7.2+ |
| Agents | Yes, with tools and memory | Actively in development |
| Streaming | Yes | Yes |
| Structured output | Yes | Yes |
Neuron AI
Open-source PHP library for building agents with multi-provider support. Its design is pragmatic and framework-agnostic: works with Laravel, Symfony, or any modern PHP project.
Covers the following cases well:
- Agents with tool use and automatic tool call loop
- Multi-provider support (OpenAI, Anthropic, Google, Ollama)
- Structured output via schemas
- Streaming with SSE support
- Conversation memory management

Symfony AI
Official Symfony component for integrating AI, introduced in Symfony 7.2. Follows framework conventions: autoconfiguration, dependency injection, YAML/PHP configuration.
Covers the following cases well:
- Native integration with Symfony’s DI container
- Tool definition via PHP attributes
- Structured output with PHP classes
- Streaming via
StreamedResponse - Conversation memory with configurable storage
Official docs: symfony.com/doc/current/ai.html
Symfony AI is in beta
The symfony/ai component was introduced in Symfony 7.2 and its API may change between minor versions. Review the CHANGELOG before upgrading in production projects.
When to use each
Use Symfony AI if you already have a Symfony project and want native integration with the ecosystem. Use Neuron AI if you have a Laravel or generic PHP project, or if you need more mature agent features.
