BREAKING: OpenAI Officially Launches GPT-6 With Two Different Brains

Breaking news straight off the wire.

OpenAI just flipped the switch on GPT-6 inside ChatGPT, and it's not one model wearing a single hat.

If you're on Plus, Pro, Business, or Enterprise, the brain answering you in the Chat tab is called GPT-6 Sol.

If you're on the Free or Go tier, you're actually talking to a different version named GPT-6 Luna.

Think of it like a restaurant running two kitchens off the same menu. One line is tuned for the VIP tables with more time and resources per dish, the other is built for speed and volume, but both are cooked from the same core recipe.

This isn't just branding flair. It signals OpenAI making a clear infrastructure call: match compute allocation to user tiers so performance stays solid whether you're paying top dollar or nothing at all.

The real question everyone's typing right now: is the Sol vs Luna split about raw intelligence, or mostly about speed and latency under the hood?

Details are still unfolding, and we're watching every update as it drops.
