Gemini 3.5 Pro misses delivery date again, Google considers stopgap
Google DeepMind's redesigned Gemini 3.5 Pro model has missed its third deadline, scheduled for 17 July 2026. Delays are attributed to persistent issues with hallucinations, leading Google to consider releasing a temporary Flash model as a substitute.
What happened?
Google DeepMind's Gemini 3.5 Pro model has once again missed its intended launch date, this time on 17 July 2026. This marks the model's third missed deadline, increasing pressure on the development team. The issues stem from continued "hallucinations," where the AI model generates incorrect or fabricated information.
