OpenAI Slashes Pricing for GPT-5.6 API to Cut Inference Costs

22    2026-07-31

On July 30, OpenAI officially rolled out price cuts for its core GPT-5.6 Luna and Terra models. Pricing for input tokens of Luna is reduced by 80%, while Terra sees a 20% discount. A high-speed Fast Mode for Sol is launched, boosting computation speed up to 2.5 times. OpenAI states automated optimization technology improves kernel performance and speculative decoding to cut operational costs. The adjustment benefits global AI developers and startups by lowering barriers for commercial implementation. Analysts believe this round of price reduction accelerates the commoditization of general large models and triggers global price competition among model providers.
