About OpenAI
OpenAI builds the GPT series. The GPT-6 generation (September 2026) ships in three sizes — Astra (flagship, $10/$50), Sol ($2/$10) and Luna ($0.10/$0.50) — that share a 1.05M-token context window and the same tooling, so teams can move workloads between price points without changing integration code. The GPT-5.6 models remain on sale as the previous generation.
