On July 9, 2026 OpenAI unveiled GPT-5.6 in three variants: Sol (the workhorse), Terra (mid-tier), and Luna (budget). Sam Altman says the models are markedly more token-efficient — Sol is reportedly 54% more token-efficient on AI coding tasks — with stronger capabilities in enterprise work, coding, and scientific research. OpenAI took a cautious rollout, opening early access to a small set of partner organizations before broader availability through mid-July.

OpenAI launches GPT-5.6 family (Sol, Terra, Luna) with big efficiency gains
Why this matters for founders
A three-tier lineup lets you route by job: Luna for cheap high-volume calls, Sol for coding and heavy reasoning, keeping spend proportional to value. The claimed 54% coding-token efficiency directly cuts the cost of AI-assisted development and any code-generation feature you ship. Combined with the Claude Opus 5 launch the same month, this is a genuine price/performance step-down — a good moment to re-price your AI feature margins.
