neuron-core/neuron-ai
Neuron is a PHP framework for building and orchestrating AI agents inside PHP applications, requiring PHP 8.1 or newer and installed through Composer. Agents are written as classes that extend a base Agent class and declare an LLM provider and a set of instructions; a SystemPrompt helper assembles the instruction text into a consistent prompt, and a console command scaffolds new agent classes. The base class handles conversation memory, tool registration and function calling, so an agent remembers earlier turns of a chat without extra code. Beyond single agents the framework covers what the maintainers describe as the whole agentic application lifecycle: LLM provider interfaces including Anthropic, data loading and retrieval augmented generation, structured output, tools and toolkits, a connector for the Model Context Protocol, and multi-agent orchestration. Its Workflow component is event driven with checkpointing, human-in-the-loop interruption, loops and shared state, and the same workflow abstraction is meant to scale from a first tutorial agent to a production multi-agent system. Streaming is supported through agentic UI protocols, with adapters for AG-UI and the Vercel AI SDK protocol, and agents can also be executed asynchronously. Because agent behaviour is probabilistic rather than deterministic, the project puts weight on observability and ships monitoring and debugging integration so that individual LLM calls, tool invocations and memory access inside a multi-step run can be inspected. Around the framework the maintainers run a vertical ecosystem with a registry of extensions, tools and technologies aimed specifically at agentic applications, plus documentation, video tutorials and a newsletter. It is intended for PHP developers who want agent functionality in an existing PHP codebase instead of moving that part of the stack to Python or JavaScript.
