GPT-6 Sol and GPT-6 Luna arrive at half the price of the models they replace

OpenAI completed the GPT-6 family today, and both new models cost exactly half what their predecessors did. They take over the seats those models held in the picker.

GPT-6 Sol replaces GPT-5.6 Sol on the Quality tier, at $2 in / $10 out per million tokens instead of $4 / $20. OpenAI positions it as the balance of intelligence and cost, and its own testing puts it ahead of GPT-5.6 Sol on professional work, factuality and coding.

GPT-6 Luna replaces GPT-5.6 Luna on the Fast tier, at $0.10 in / $0.50 out instead of $0.20 / $1.20. That makes it the cheapest model we offer - good for simple pages, quick edits and high-volume work.

Both keep the 1M-token context window and the 128K maximum answer length of the models they replace, and we pass the full price cut through, so the same work costs fewer credits.

Nothing you have pinned breaks. GPT-5.6 Sol and Luna stay available to existing chats; chats and preferences set to them move to the GPT-6 equivalent automatically, which is cheaper for the same job.
