Will GPT-6 release introduce a different size/performance tier structure?

Question

In an industry with already poor average naming track record, OpenAI is still unrivaled in naming their models without any consideration for common sense, user experience, or marketing foresight.

Now, with GPT-6 release allegedly only weeks away, many are speculating that the new flagship will be in a size category of its own akin to Anthropic's Mythos/Fable. But then how does it fit into the neat current Sol/Terra/Luna naming scheme? Would a potential higher tier take on the name of some bigger star (Antares?) or the entire Milky Way galaxy ("Galaxias"?)? So many questions!

Note on the last option: in the absence of direct testimonials from Sam & Co, I will go by consensus opinion of industry analysts and my best informed judgment; resolution might be delayed in this case or may have to rely on a separate poll or market intended to gauge opinions on the matter.

Per Manifold Markets prediction market, No, Sol remains the highest tier and has similar speed and pricing as 5.6 (the status quo answer), followed by No, but one or more models in existing tiers CLEARLY become bigger (as reflected by their speed and pricing or other strong signals) and Yes, a higher tier introduced with a change in naming scheme are most likely.
