It outputs 1107 tokens per second, up from Mercury 2's 1009, with context length doubled to 260,000 tokens. Inception rates its quality on par with GPT-5.6 Luna (Low), Gemini 3.5 Flash-Lite, and Claude Haiku 4.5. Output pricing stays at $0.75 per million tokens while input pricing drops to $0.20, with an 80 percent launch discount on OpenRouter.","whyItMatters":"Mercury 2.5 puts diffusion-based generation on par with the cost-efficient frontier models GPT-5.6 Luna Low and Gemini 3.5 Flash-Lite while cutting input pricing, making parallel token generation a practical option for latency-sensitive agent workloads.","webCardHtml":"\u003cp\u003eMercury 2.5 applies the diffusion approach used in image generation to text, building a rough draft of the whole answer and refining multiple tokens in parallel instead of deciding one token at a time.
