How guest access works
Open the GPT-5.6 Luna page and make one eligible text run as a guest. The trial is tied to the live modcov route, so this guide does not create a separate model or a second execution path.
The guest run does not promise repeated free use. After sign-in, the route shows an estimate of 2 Credits per run so you can decide whether to continue with the same named model.
Read the declared positioning and capabilities as a fit guide, then check the generated response for your own context. Model names identify the route you choose; they do not imply an affiliation with the model provider.

The model page contains the actual text workspace and the current access terms. Use this intent page to confirm fit, then move to that route for the one eligible guest run.
