GPT-6.1 Sol and GPT-6 Luna join the model picker.

Two new OpenAI models are live in Morrison Chat and in automations: GPT-6.1 Sol and GPT-6 Luna. Same Skills, same integrations, same crawl, switchable per message.

GPT-6.1 Sol

Close to GPT-6 Astra on demanding work, at the $$ cost tier instead of Astra’s $$$$. It is the OpenAI model to use for most professional work: a brief from three data sources, a rewrite of a comparison page, an analysis of what changed in a segment. Keep Astra for the questions that need the very top of the range.

GPT-6 Luna

The fastest, lightest OpenAI model, at the $ tier. Built for high-volume, well-defined tasks: titles and meta descriptions across a list, a quick classification of many pages, short summaries.

The OpenAI lineup

GPT-6 Astra at the top, GPT-6.1 Sol and GPT-6 Luna below it. The GPT-5.6 family, Sol, Terra and Luna, stays in the main list too, so nothing you set up changes.
