OpenAI has launched three new versions of its GPT 5.6 model: Soul, a frontier model; Tara, a balanced everyday model; and Luna, a cheaper, high-volume model. The speaker expresses a strong preference for GPT 5.6 Soul, describing it as their "heart's favorite."
“First, Open AI is releasing three new versions of their GPT 5.6 model. Soul, which is the next generation frontier model, the brainiest of the brainiest. Tara, which is a balanced model for efficient everyday work. And Luna, which is sort of akin to their mini or nano models, which is cheap and affordable for high volume work.”
“So you're gonna have these three versions of the models. I don't know if these beautiful images are exactly how we should think about the relative capabilities. This big sun, this medium earth and this tiny moon. But I will say my love letter that is this podcast today, is written directly to GPT 5.6 Soul. This big model is the one I love.”
