GPT CLI
An early open-source command-line interface for ChatGPT, enabling developers to interact with GPT models directly from their terminal.
GPT CLI was an early attempt to make language models feel native to developer workflows. Before polished coding assistants were common, the terminal was the fastest place to test prompts, inspect outputs, and chain model calls into normal work.
The project kept the interface deliberately small: ask, receive, iterate. That made it useful as a scratchpad for engineers who wanted model access without switching context.
It now reads like a time capsule from the first serious year of developer-facing LLM tooling, but the underlying idea still matters: models become more useful when they live where work already happens.
