OpenAI cuts GPT 5.6 Sol pricing by 20% through at least November 2026

According to OpenAI's developer documentation, the company reduced API pricing for GPT 5.6 Sol and Codex credits by 20% with a commitment through at least November 21, 2026. The pricing action directly lowers costs for developers integrating OpenAI's latest model into agent systems and coding applications.

Update (2026-08-29): According to Hacker News discussions, OpenAI added 5-hour usage caps for Codex across all subscription plans except Pro, reversing prior policy. Developers report hitting limits faster than expected and cite reduced productivity, with multiple users questioning the constraint's impact on development workflows.
