Where this family fits.
Starting a GPT-5.6 chat with paid model access
Requests that combine text with a screenshot, diagram, or other uploaded image
Keeping GPT-5.6 model choice explicit when switching between later requests
What not to assume.
Vizify does not run Luna, Terra, and Sol in parallel for one request
Terra and Sol require current Paid-model entitlement
This page does not claim external benchmark leadership or permanent performance differences between variants
Three variants with visible product boundaries
Vizify currently exposes GPT-5.6 Luna, Terra, and Sol as separate model choices. All three require paid access. The page keeps that distinction explicit instead of presenting one ambiguous GPT-5.6 button.
GPT-6 is the newer generation
GPT-6 Luna and GPT-6 Sol succeed GPT-5.6 Luna and GPT-5.6 Sol, and GPT-6 adds a third model, Astra. There is no GPT-6 Terra. All three GPT-5.6 variants remain in the Vizify catalog, so existing conversations keep working and you can still pick them. When you want the newer model, switch to its GPT-6 counterpart for your next request. The GPT-6 models and their Fast variants are documented on the OpenAI GPT page.
Text and image input
All three GPT-5.6 variants are currently included in the Vizify vision list. That means the customer App can pass supported image uploads with the request after it validates file and account requirements. This page does not imply that every chat model in the broader catalog has the same input support.
Capability review

Which GPT-5.6 model does this page open?
The primary action opens Vizify with GPT-5.6 Luna as a one-time launch selection. The App validates the model against its live catalog before use.
Is GPT-5.6 Luna the default model in Vizify?
No. GPT-5.4 Mini is the default. Luna requires Pro or a credit pack purchase. The App still validates the live catalog and account access before each request.

Yes. Luna, Terra, and Sol are currently marked for text and image input in the Vizify app profile. Upload handling and model access are still validated by the App.
Are GPT-5.6 Terra and Sol in the Basic tier?
No. The current customer catalog lists Terra and Sol in the Paid tier, so the App checks Paid-model entitlement before sending a request.

Yes. GPT-6 Luna and GPT-6 Sol succeed GPT-5.6 Luna and Sol, and GPT-6 adds Astra. GPT-6 has no Terra variant. All GPT-6 models, including their Fast variants, are covered on the OpenAI page at /models/openai/. GPT-5.6 stays available, so you can keep using it.
Does Vizify compare all three GPT-5.6 answers automatically?
No. Vizify uses one selected model for each request. You can switch variants before a later request, but the page does not promise parallel comparison or consensus.
