Mirascope LLM SDK

A developer-first Python and TypeScript toolkit for building LLM applications using native code patterns instead of complex abstractions.

Mirascope is the LLM anti-framework designed for engineers who want full control without the overhead of heavy abstractions. It provides a unified interface for frontier models like Claude 3.5 Sonnet and GPT-4o, allowing you to swap providers by simply changing a string. By leveraging Pydantic for structured outputs and OpenTelemetry for native observability, Mirascope ensures your code remains readable and easy to debug. Whether you are building autonomous agents with tool-calling capabilities or complex RAG pipelines, Mirascope keeps your logic in standard Python or TypeScript (using the @llm.call decorator) so you can focus on the prompt, not the plumbing.
