About

GPT-5.6 Luna (also written 5.6 Luna) is a model from OpenAI. The provided material contains no official specification page for it, so details are limited to what creators have said. It appears to be a lighter variant in the GPT-5.6 family, aimed at tasks that do not need a frontier-level model.

A YouTube creator (Matt Wolfe) showed it being used for cloning a repository and installing dependencies, on the reasoning that setup work does not need a strong model. Another (Matthew Berman) described it as an OpenAI model whose price had been cut by about 80% a few weeks earlier. Neither claim is confirmed by official pages in the supplied text.

Access is presumably through OpenAI's API and ChatGPT, but this is not confirmed in the provided material. Context window, benchmarks, exact pricing and release date are not given, so they are left unspecified here.

Key features
