GPT-6 Sol and Luna Launch With 50% Price Cuts

OpenAI released two new models this week, GPT-6 Sol and the smaller GPT-6 Luna, both priced roughly 50% below their predecessors — landing just 90 minutes after Anthropic released its own competing model, Claude Opus 5.5.

Key points:

• GPT-6 Sol is priced at $2 per million input tokens and $10 per million output tokens, aimed at strong everyday performance without premium frontier-model prices.

• The smaller, faster GPT-6 Luna runs as low as $0.10 / $0.50 per million tokens, aimed at high-volume, lower-complexity tasks.

• Price per million tokens is roughly the cost of running the model on a large chunk of text — a lower price means a business can use the AI far more often for the same budget.

• The price cuts continue a pattern of frontier labs competing more aggressively on cost per token as capability gaps between top models narrow.

Why It Matters: A 50% price cut on general-purpose models means existing OpenAI customers should re-evaluate their cost projections immediately — rates budgeted even two months ago are already out of date.
