Write and analyze with GPT-5.6 Luna
GPT-5.6 Luna is the light format of OpenAI's 5.6 series: fast, very economical, and yet clearly more capable than the old Mini and Nano. It is the model for tasks in volume, labelling, summarising, extracting, producing short variants, rewriting one line in ten tones, where the cost per call decides whether a workflow is viable. It also reads connected images. As soon as the request gains depth, GPT-5.5 takes over within the same family, with the same style of answer.
The GPT for tasks in bulk
GPT-5.6 Luna is the light format of OpenAI's 5.6 series: twenty cents per million input tokens, one dollar twenty per million output, a one-million-token context, images read. Clearly more capable than the old Mini and Nano, it is built for volume: labelling, summarising, extracting, producing ten short variants, rewriting a line in several tones.
On the canvas, it is the model you wire in when a workflow calls the Text node on every iteration and the cost per call decides whether it is viable. As soon as the request gains depth, GPT-5.5 takes over within the same family.

Frequently asked questions
Is GPT-5.6 Luna enough to write an image prompt?
Yes, for simple prompts and variants. For a long brief or detailed art direction, GPT-5.5 or Claude Sonnet 5 give a more precise text.
How much does a message sent to GPT-5.6 Luna cost?
Around 1 credit(s) per message, that is $0.01 (1 credit = $0.012). The cost shows before sending, with no separate subscription and no API key to manage: the same credits pay for all 88 models in the catalog.
Do I need a separate subscription to use GPT-5.6 Luna?
No: GPT-5.6 Luna is included in Imaginode, with no API key and no account with the provider. A single credit balance covers all 88 models, text, image, video and voice, and also powers the assistant that builds complete workflows.

No: GPT-5.6 Luna runs server-side, in the browser, mobile included. Imaginode's node canvas wires its renders to the other models (references, camera, styles) with nothing to install.
