AI made code cheaper to write. The cost of owning it? Not so much.

For small, bounded requests, a first patch can replace scope debates with evidence: inspect the diff, price the risk, then decide.

The cost of saying yes has changed. The cost of saying no should too.

GPT-5.6 comes in three variants:
☀️ GPT-5.6 Sol: the highest reasoning ceiling in the family. Best for complex reasoning over large codebases and demanding, long-running agentic work.

🌎 GPT-5.6 Terra: the balanced default. A strong all-round choice for everyday interactive and agentic coding.

🌕 GPT-5.6 Luna: a lightweight, cost-efficient variant for smaller, faster tasks and the lowest-cost option in the family.
