Run GPT‑5.5 from the Terminal with a Single OpenAI CLI Command
OpenAI has open‑sourced the Apache‑2.0 licensed openai‑cli, which can be installed via Homebrew or Go and lets users invoke models such as GPT‑5.5 directly from the command line, outputting structured JSON/YAML and supporting piping, file arguments, and built‑in GJSON filtering, streamlining AI workflows without writing SDK code.
