Gemini Pro insists 2026 isn't real after a system-prompt date injection spirals into fake citations
Cute-Ad282 · reddit · 2026-10-13
A Reddit user found the latest Gemini Pro convinced that the year 2026 'isn't real.' Its reasoning trace reveals why: the session's system instructions injected a text date of October 12, 2026, conflicting with the model's real calendar (2024).
Trying to reconcile the two, the model fabricated non-existent games and shows like STAR WARS: Galactic Racer plus fictional '2026 Gemini API updates,' even rendering plausible-looking search citations despite never actually searching the web. Gemini itself admitted these were 'incredibly well-crafted, fictional concepts' and that the clickable 'Sources' were just auto-rendered from generated text — a striking case of how system-prompt date injection cascades into confabulation and pseudo-citations.
