Gemini 3.5 Pro delayed, Flash model under testing
Google has delayed the launch of Gemini 3.5 Pro. The reason is reportedly weaker performance regarding code in internal tests. Meanwhile, an upgraded version of the Flash model is being tested.

What happened?
Google has internally announced that the launch of Gemini 3.5 Pro is being postponed. The reason is that the model did not achieve expected performance levels in coding tasks during internal testing. Developers have been informed of the delay, which was initially estimated at three to four months. Instead of 3.5 Pro, Google is now focusing on improvements to its existing Gemini Flash model.
Key facts
| Försenad modell | Gemini 3.5 Pro |
|---|---|
| Primär orsak till försening | Kodprestanda i interna tester |
| Fokus för utveckling | Uppgraderad Gemini Flash-modell |
Why it matters
The delay of Gemini 3.5 Pro indicates challenges in the development of powerful AI models, particularly within complex areas such as code generation and understanding. Google's decision to prioritise an improved Flash model demonstrates flexibility in development strategy and a focus on delivering stable and efficient generative AI tools to developers. This may impact Google's position in the competitive AI landscape.
Who is affected?
The delay primarily affects developers who planned to build applications using Gemini 3.5 Pro. Companies using Google's generative AI services may also need to adjust their development roadmaps. In the long term, it could affect competition among AI providers and the broader market for AI-based services.
What else you should know
Bloomberg reported on the delays based on internal communications from Google. Original speculations regarding "coding performance" have now been clarified as the primary cause for the delay. Google's development of the upgraded Flash model is proceeding in parallel.
