OpenAI will slash API and credit fees for its GPT‑5.6 Sol model by more than 20% for three months, lowering costs to $4 per million input tokens and $20 per million output tokens.
OpenAI announced on Friday that it will slash the API and credit prices for its flagship GPT‑5.6 Sol model by more than 20 percent for the next three months. Effective 22 August 2026, developers will pay $4 per million input tokens and $20 per million output tokens – a 20 % cut on input pricing and a 33 % reduction on output costs. The promotional rates are slated to run at least until 21 November 2026 and apply to the API as well as to eligible ChatGPT Work and Codex credit plans; existing Pro, Plus and Business subscriptions will keep their current pricing.
OpenAI said the move comes as it faces mounting pressure on enterprise API margins from rivals such as Anthropic and DeepSeek. By lowering the cost of its most capable model, the company aims to keep developers on its platform while pushing the frontier of capability and efficiency. The discount also signals a shift in OpenAI’s pricing strategy after a period of steady rates, suggesting the firm is willing to trade short‑term revenue for broader adoption in a tightening competitive landscape.
Stakeholders will be watching whether the discount is extended beyond the three‑month window and how quickly usage volumes respond. Analysts will also track whether Anthropic, DeepSeek or other entrants adjust their own pricing, potentially sparking a broader price war in the AI‑as‑a‑service market. Finally, the impact on OpenAI’s upcoming product rollouts – from ChatGPT Work enhancements to new Codex credit offerings – will indicate how the price cut fits into its longer‑term growth plan.
