Gemini CLI User Report: gemini-3-flash-preview Unavailable for Some Accounts

In a Linux community discussion, users have reported inconsistent availability issues when trying to use the gemini-3-flash-preview model in the Gemini CLI. Tests showed that out of six accounts, only two successfully accessed the model, while the rest returned an API 404 error, indicating “Requested entity not found.” This phenomenon has raised questions about Gemini service access permissions, account limitations, or the model’s deployment status. For AI developers relying on this model, this issue could lead to development roadblocks, necessitating attention to official Google updates or community solutions. The discussion highlights the importance of access control in AI services and the potential challenges users may face with experimental features.
