# OpenAI Releases GPT-5.6 Family: Sol, Terra, Luna Variants for Different Tasks

> OpenAI has stopped pretending one model fits every job. GPT-5.6 ships as three named variants: Sol, the frontier reasoning tier at $5 in and $30 out per million tokens; Terra, an everyday workhorse at $2.50 and $15 that OpenAI says matches GPT-5.5 quality for half the cost; and Luna, the fast, cheap option at $1 and $6. The company claims Sol is 54% more token-efficient than Anthropic's Fable 5 on agentic coding, and Sam Altman is talking it up as the best model in the world on cybersecurity tasks. The tiering matters more than the leaderboard boasts. Splitting a model family by cost and speed is an admission that most work does not need frontier reasoning, and that paying frontier prices for it is waste. It also sharpens the fight with Anthropic and the cheaper open-weight challengers, since the real battleground now is which model gives acceptable answers at the lowest price. Rollout covers Grok Build, Cursor and SpaceXAI's console, with the EU getting access mid-July.
