A coding agent optimized for low-cost models. Blog post ↗

macOS and Linux:

Then type i or interpreter in your terminal to start a session.

Open Interpreter is a fork of OpenAI's Codex, with a focus on emulating the agent harness that gets the best performance out of low-cost models.

Use /harness to switch the active harness:

> /harness

native
claude-code
claude-code-bare
zcode
kimi-cli
qwen-code
deepseek-tui
swe-agent
minimal

Read more in the harness docs and model provider docs.

Open Interpreter ships with a QA skill that lets any model operate and test interfaces. It can drive web apps in a real browser with agent-browser, or operate and test native apps with trycua.

• Runs commands inside native sandboxing on macOS, Linux, and Windows.
• Switches providers and models from the TUI with /model.
• Inspects or switches Rust-native model harnesses with /harness.
• Tests web and native apps through the built-in QA skill.
• Runs as an Agent Client Protocol agent for editors with interpreter acp.
• Keeps config and session state local under ~/.openinterpreter.
• Supports exec, MCP, skills, hooks, permissions, and AGENTS.md.
