gpt 6

“GPT‑6” refers to OpenAI’s sixth‑generation frontier language model family, first released under the name GPT‑6 Astra in early September 2026 and later expanded with variants such as GPT‑6 Sol, GPT‑6 Luna, and GPT‑6.1 Terra.[1][2][5][8] It powers new ChatGPT features including an “Intelligent UI” with interactive widgets and integrated computer use, and is available across OpenAI’s API and ChatGPT product tiers.[2][3][4][6]

OpenAI announced GPT‑6 Astra on September 3, 2026, with rollout to select organizations and API platforms, and wider general availability from September 4.[1][6][13][17][22] Sol and Luna variants followed on September 22, 2026, with broader ChatGPT access from October 7, 2026, while GPT‑6.1 Terra launched October 26, 2026 as a mid‑sized, computer‑use‑focused successor to GPT‑5.6 Terra.[3][5][8][10][15][16][18] Some earlier sources from April 2026 had suggested GPT‑6 was still only a future plan, which is now outdated given the confirmed September–October 2026 releases.[19]
