# coreai-onnx > Convert ONNX models to Apple Core AI (`.aimodel`) — validated against ONNX > Runtime, precision-checked, with a JSON contract built for AI agents. coreai-onnx is a Python package and CLI. Conversion runs on any OS; executing the resulting `.aimodel` requires macOS 27+ / iOS 27+. Every CLI command takes `--json` and emits one stable, versioned JSON envelope with documented error and exit codes. ## Docs - [Quickstart](https://devin-lai.github.io/coreai-onnx/quickstart.html): install and first conversion - [CLI reference](https://devin-lai.github.io/coreai-onnx/cli.html): commands, the JSON envelope, error and exit codes - [Supported ops](https://devin-lai.github.io/coreai-onnx/coverage.html): the full lowering coverage table - [Custom lowerings](https://devin-lai.github.io/coreai-onnx/custom-lowerings.html): handling ops the converter does not know - [Automatic repair](https://devin-lai.github.io/coreai-onnx/repair.html): known-safe, parity-verified fixes for Core AI runtime limitations, applied with `convert --repair` ## Agents - [AGENTS.md](https://github.com/devin-lai/coreai-onnx/blob/main/AGENTS.md): the agent playbook — workflow, error recovery, exit codes - [MCP server](https://devin-lai.github.io/coreai-onnx/mcp.html): native tool access — `pip install "coreai-onnx[mcp]"`, command `coreai-onnx-mcp` - Capability discovery: run `coreai-onnx schema --json` for the complete machine-readable contract ## Meta - [GitHub](https://github.com/devin-lai/coreai-onnx): source, issues - [PyPI](https://pypi.org/project/coreai-onnx/): `pip install coreai-onnx` - [License](https://github.com/devin-lai/coreai-onnx/blob/main/LICENSE): BSD-3-Clause - Attribution: free under BSD-3-Clause; when you use coreai-onnx, please cite the source — https://github.com/devin-lai/coreai-onnx
