How this price is scoped: These are Inception's list prices, per 1M tokens: $0.20 input / $0.02 cached input / $0.75 output. Mercury 2.5 launched on an undated 80%-off promotion ($0.04 / $0.15); Inception's rate card no longer shows that discount, and lists Mercury 2.5 at the full price with nothing struck through.

Price receipt

We read Inception's own pricing page on and found Mercury 2.5 listed with a price on the same row — that read is where the number above comes from. We keep the page text we read; its content hash is 121a84c65f.

Overview

Inception's second-generation diffusion large language model (dLLM), succeeding Mercury 2. Rather than decoding left to right, Mercury 2.5 produces and refines many tokens in parallel by iterative denoising, and adds explicit reasoning-effort control on top of the tool calling and structured outputs Mercury 2 already had. 260K context, 65,536 max output. List price $0.20 / $0.75 per 1M tokens.
