summary: "Developers using the company's latest high-reasoning tool will see a reduction in fees for the next three months as the firm focuses on improving inference efficiency. OpenAI is dropping API and credit pricing for GPT-5.6 Sol by over 20%, with the discount already live for API users and currently rolling out to Codex and ChatGPT Work. Users on Pro, Plus, and Business subscriptions will see no change to their current usage limits. The pricing shift comes as rivals like Anthropic face negative feedback over Opus 5 and strict rate limits for Fable 5, and as low-cost Chinese models including DeepSeek 4 Flash and the rumored GLM-5.3 Flash enter the market. OpenAI is also expanding its compute capacity with a new 8 GW buildout deal to support its more efficient models. These moves reflect a broader industry trend of falling year-over-year inference costs for state-of-the-art AI."
