phalanx/ai
==========

[](#phalanxai)

An agentic runtime for PHP 8.4+ that treats LLM interactions as scoped, typed, stream-native computations. Define tools as invokable classes, wire providers as services, and let the Phalanx runtime handle concurrency, retries, streaming, and cleanup.

Phalanx/ai brings concurrent tool execution, streaming with backpressure, and multi-agent coordination to PHP -- capabilities that previously required leaving for another language.
