Mirascope lets you use any frontier LLM through one unified interface. In Python you decorate a function with `@llm.call("anthropic/claude-sonnet-4-5")` and call it; the model is named by a provider/model string. The README shows three steps: a basic call, structured output by passing a Pydantic model as `format=` and reading it with `.parse()`, and an agent loop where functions marked `@llm.tool` are passed as `tools=` and the response is resumed with `response.resume(response.execute_tools())` while it has tool calls. Streaming, async and multi-turn conversations are covered in the docs.

Install with `uv add "mirascope[all]"`. The repository is a monorepo with a Python implementation (with examples), a TypeScript implementation, a `cloud/` full-stack application (React frontend and Cloudflare Workers backend) and unified docs. It follows Semantic Versioning, and CI runs spell-check, Python lint and type checks, TypeScript lint and a docs build.

Licensing is split: the code is MIT unless otherwise specified, but the `cloud/` directory is under a proprietary license, and subdirectories may carry their own LICENSE files. It was last pushed on 2026-10-12. This review is based on the README and repository data; we have not run it ourselves.

This write-up is based on the project's README and public repository data. We have not hand-tested the tool. Data as of 2026-10-27.

Features

01Unified interface for all frontier LLMs
02Call LLMs using simple decorators
03Generate structured output with Pydantic models
04Build agents with integrated tool-use
05Supports streaming, async, and multi-turn conversations
02

Why choose it

+One decorator-based interface for calling different LLM providers, named by a provider/model string
+Structured output with Pydantic models and tool calling via `@llm.tool`, both shown in short README examples
+Python and TypeScript implementations in one monorepo, with unified docs
+Semantic Versioning and CI for lint, type checks and docs; MIT for the main code; last push 2026-10-12

Trade-offs

!The `cloud/` directory is proprietary-licensed, so the repository is not uniformly MIT
!The README is short and points to the docs site for streaming, async and multi-turn use
!The agent loop is written by hand in the example (a `while response.tool_calls` loop), so it is a thin library rather than a full agent framework
