OpenAI Price Cuts: GPT-5.6 Luna Now 80% Cheaper

OpenAI is dramatically cutting prices for some of its AI models, with reductions up to 80%. This move makes their GPT-5.6 Luna model the most attractive in intelligence-per-dollar rankings. Here's the thing: CEO Sam Altman announced an 80% drop in developer pricing for the lightweight GPT-5.6 Luna model. This brings API costs down to 20 cents per million input tokens and $1.20 per million output tokens. What's interesting is OpenAI also cut rates for its mid-tier GPT-5.6 Terra model by 20%. They also introduced a "fast mode" for their flagship GPT-5.6 Sol, which boosts performance speed up to 2.5 times. These three models were all introduced earlier this month. The bottom line: These price cuts position OpenAI competitively against Chinese rivals like Zhipu AI and MiniMax, who have been gaining ground with aggressive pricing. This matters because lower costs could accelerate AI integration across many applications and services.
