Both of them AI frameworks built in PHP. Both have everything — agents, RAG, chat, MCP. You can compare them to LangChain and LangGraph.

But one difference stood out fast.

Neuron AI → easy to follow

Symfony AI → harder to understand

Not because it’s weaker. Because the thinking isn’t obvious. The documentation flow don’t give clarity.

Symfony have given multiple examples. But these examples don’t have comments in the code and make it hard to understand.

I am still exploring both of them. Will write a post once I have some solid understanding and decide which one to adopt forever.
