Gemini 3.5 Pro misses delivery date again as Google weighs stopgap
Google DeepMind's redesigned Gemini 3.5 Pro model has missed its third deadline, scheduled for 17 July 2026. The delays stem from persistent issues with hallucinations, prompting 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 team. The issues arise from continued "hallucinations," where the AI model generates incorrect or fabricated information.
