Google is months behind schedule on the release of Gemini 3.5 Pro as the company works to improve the coding capabilities of its most powerful flagship AI model.
The delay has frustrated engineers, researchers and managers who are concerned that Google could lose ground to Anthropic and OpenAI, according to current and former employees familiar with the matter.
Google was widely expected to unveil Gemini 3.5 Pro during its developer conference in May. The company updated the model’s training data late last month in an effort to improve coding performance, but the results were disappointing.
Alphabet shares fell as much as 3.2% on Thursday following the report.
The company said it is testing Gemini 3.5 Pro, an upgraded Flash model and other systems with partners. Google is also discussing the model’s capabilities and testing standards with the US government.
