OpenAI cuts GPT-5.6 prices, introduces Fast mode #1 📝 OpenAI News Advancing the price-performance frontier with GPT 5.6 - OpenAI cut GPT‑5.6 prices—Luna is 80% cheaper and Terra 20% cheaper—and introduced Fast mode (replacing Priority Processing) so GPT‑5.6 Sol can run up to 2.5× faster than Standard at 2× the price. The company says model, inference, and agent improvements reduced end‑to‑end serving cost by 20% and improved token‑generation efficiency >15%, with claims that Luna delivers near‑frontier performance at roughly $0.06 per task and nearly 9× the speed (customer benchmarks include Blitzy’s 2.2× more context with 8.5× fewer output tokens at 87% lower cost and Dust’s 40% faster/40% cheaper results).
