ChatGPT 6 Release Date: Rumors & What’s Actually Confirmed

Update, July 11, 2026: The “Spud” model everyone expected to become GPT-6 shipped on April 23, 2026 as GPT-5.5, not GPT-6, hitting 88.7% on SWE-bench Verified and 82.7% on Terminal-Bench 2.0 with 60% fewer hallucinations than GPT-5.4. OpenAI has since gone further and made GPT-5.6 generally available on July 9, 2026, in three tiers (Sol, Terra, and Luna).

OpenAI says GPT-5.5 produces 60% fewer hallucinations than GPT-5.4. The Polymarket prediction (78% by April 30) came in on time; the “high 70s on SWE-bench Pro” benchmark leak did not, with the actual score landing at 58.6%, still behind Claude Opus 4.7’s 64.3%.
