OpenAI released a builder guide for GPT-5.6, showing how to reduce agent costs. Official data shows the same search test scoring 84 points costs $33.27 with the previous generation, but only $1.33 with the smallest new model. The guide covers model selection, reasoning effort adjustments, and three new API switches. Six startups reported up to 21% fewer input tokens, 28% less uncached input, and costs reduced to 1/18th. Notably, official charts show turning reasoning effort to minimum actually increases cost.
