Open Interpreter
Open-source terminal coding agent tuned for low-cost, open-weight models
Overview
Open Interpreter is an Apache-2.0 terminal coding agent, forked from OpenAI's Codex CLI and written in Rust, that emulates each model maker's preferred harness to get more from Kimi, Qwen, GLM and DeepSeek, with OS-level sandboxing, MCP and ACP editor support, plus the Interpreter desktop app. Free; desktop Pro $20 a month.

Open Interpreter has reinvented itself as a serious coding agent for developers who want to use cheaper open-weight models well, and its harness-emulation idea and native sandboxing are genuine strengths. It is now built on OpenAI's Codex CLI rather than its own engine, its benchmark gains are self-reported, and the original Python code-runner lives on only as a community fork. Well worth trying for cost-conscious developers; those who relied on the old tool should look at the fork.
What we found
Open Interpreter is now an open-source coding agent for the terminal, built for low-cost and open-weight models. In 2026 the project relaunched as a fork of OpenAI's Codex CLI, written in Rust and licensed under Apache 2.0, replacing the original Python tool that let a language model run code on your computer. It reads and edits code and runs commands inside a native operating-system sandbox on macOS, Linux and Windows, asking for approval before touching anything outside the workspace, and supports MCP, AGENTS.md, the Codex SDK and editors that speak the Agent Client Protocol, such as Zed, JetBrains IDEs and VS Code. Its distinctive idea is harness emulation: it drives Claude through a Claude Code-style harness, GPT through Codex, and models such as Kimi, Qwen, GLM and DeepSeek through emulations of their makers' recommended setups. On its own Terminal-Bench 2.1 runs, DeepSeek V4 Flash solved 53 of 89 tasks in Open Interpreter against 42 in OpenCode, a vendor result. Releases ship frequently, the latest on 30 September 2026.
A companion desktop app, Interpreter, adds hosted models, experimental browser and macOS control, and Word and Excel editors built on ONLYOFFICE. Open Interpreter Inc. is based in Seattle, where its creator Killian Lucas started the project in 2023; it cancelled its 01 Light hardware in 2024 and refunded buyers. The classic Python version lives on as a community-maintained AGPL fork.
The terminal agent is free. The desktop app's Free plan lets users bring their own API keys or sign in with ChatGPT; Pro costs $20 a month for hosted models, four times Free's usage and macOS control; and Business costs $60 for three times Pro's usage, with dedicated support by request. Requests to hosted models are logged for up to 30 days.
We found no current independent reviews. Open Interpreter suits developers who want a capable coding agent that gets the most out of cheaper open-weight models.
