IT Home Feb 27 news: Google yesterday announced on its official developer forum that it will stop providing Gemini3Pro Preview in the Gemini API and AI Studio starting March 9.

Google recommends that users migrate to the Gemini3.1Pro Preview version. IT Home has included the updated timeline below:

March 6:

If you are using the -latest alias, please note that we will switch it to Gemini3.1Pro Preview. March 9:

Gemini3Pro Preview will officially be discontinued. Please migrate to the 3.1 version before then to avoid service interruptions.

Some developers have expressed concerns. They believe that the 3Pro Preview is more suitable for writing scenarios. Although the 3.1 version is far better in programming, math, and other areas, it is much weaker when it comes to writing content, especially in terms of humor. In addition, the new model has a high rate of hallucinations in certain tasks.
