Ax

Ax is a compiled framework for building AI features and agents using DSPy-style programming in TypeScript, Python, Java, C++, Go, and Rust.

Ax is a framework for building AI features and agents that integrates with existing application stacks. It uses DSPy-style programming to define inputs and outputs, allowing developers to optimize instructions and examples based on automated evaluations. The framework supports Recursive Language Model agents that execute code steps to inspect data and interact with tools. It provides native libraries for TypeScript, Python, Java, C++, Go, and Rust, ensuring consistent behavior across these languages. The platform includes support for structured schema output, audio transcription, and integration with the Model Context Protocol.
