Alphabet shares fell following the delayed release of Gemini 3.5 Pro

Alphabet's shares fell 2.3% on Thursday after Bloomberg reported that Google's most powerful artificial intelligence model, Gemini 3.5 Pro, will be released several months later than originally scheduled.

According to the publication, the delay is due to additional improvements in the model's capabilities, particularly in the coding direction. Sources indicate that this has caused discontent among Google's engineers and AI researchers, who fear the company is losing ground to competitors.

Recently, OpenAI and Meta have introduced new AI models that outperform Google's current systems in the coding domain. According to Bloomberg, Google updated Gemini's training data last month, but the results obtained did not meet expectations.

A Google spokesperson stated that the company continues to actively develop various AI models while simultaneously striving to make their use economically accessible to users.

According to the spokesperson, Gemini 3.5 Pro, the updated Flash model, and other AI systems are currently in the testing phase with partners. The company is also collaborating with the U.S. government on testing and regulating the safety of AI models.

Bloomberg notes that Google's large-scale organizational structure and integration of AI technologies into products such as Search, Maps, and YouTube often slow down the process of launching new models.
