Google has launched Gemini 2.5 Pro, its most expensive AI model, with API pricing reflecting its advanced capabilities in coding, reasoning, and math. For input prompts up to 200,000 tokens, it costs $1.25 per million input tokens and $10 per million output tokens. Developers have responded positively to the pricing, though it is more costly than previous models. High demand has driven an 80% increase in usage on Google's AI Studio platform this month. This trend of rising prices among flagship AI models raises questions about future costs in the industry.
