Google has introduced Gemini 2.5 Pro, its highest-priced AI reasoning model, with new API pricing announced on Friday. For prompts up to 200,000 tokens, costs are set at $1.25 per million input tokens and $10 per million output tokens. In contrast, for larger prompts, rates increase to $2.50 and $15 respectively. This model surpasses previous offerings from Google and other competitors in terms of cost. Despite the high pricing, initial feedback from developers has been positive due to its advanced capabilities and performance. Demand is soaring, reflected in an 80% usage increase on Google's platforms.
