Frontier Large Language Model (LLM) API prices, which had been stable for five months, saw significant shifts in August. DeepSeek tripled its peak rate for its V4 Pro model by introducing a tiered pricing schedule based on time of day. OpenAI reduced the price of its GPT-5.6 Sol model by 29%, though this promotional pricing is guaranteed only through November 2026. Despite these changes, the overall index of flagship LLM prices decreased by 5.7% for the month, largely due to the DeepSeek price increase being offset by OpenAI's reduction and other models maintaining their previous rates.
