# OpenAI GPT-5.6 Family Launches with Sol, Terra, Luna Models

> OpenAI has rolled out its GPT-5.6 family, splitting the release into three tiers aimed at different jobs. Sol is the flagship built for hard reasoning and coding, priced at 5 dollars per million input tokens and 30 dollars per million output. Terra targets everyday tasks at roughly the quality of the previous generation for about half the cost, and Luna is tuned for speed and affordability. OpenAI claims Sol edges out a leading competitor on an agent-focused evaluation, though as always such head-to-head numbers deserve a skeptical eye until outsiders reproduce them. The more interesting move is the tiering itself, which pushes buyers to match the model to the task rather than paying top rates for everything. That segmentation is where the market is heading. As AI shifts from novelty to infrastructure, cost per token starts to matter as much as raw capability, and vendors compete on giving customers a cheap lane and a premium lane. GPT-5.6 is OpenAI formalizing that reality across its lineup.
