Bye-bye, Gemini CLI; Google's gone and swapped you for a closed-source AI

Summary

AI + ML Bye-bye, Gemini CLI; Google's gone and swapped you for a closed-source AI Most users lose access June 18 - unless you’ve got enterprise creds or paid API keys Pour one out for the Gemini Command Line Interface.

The change also affects Gemini Code Assist for GitHub, which won’t allow new installations beginning June 18, and will stop serving requests in the following weeks. Enterprises appear to be getting a pass, however, with Google noting that those using Gemini CLI or its IDE extensions through a Gemini Code Assist Standard or Enterprise license won’t see any changes in their access, nor will Gemini Code Assist for GitHub users accessing the tools through their enterprise Google Cloud accounts. “Gemini CLI will remain accessible via paid Gemini and Gemini Enterprise Agent Platform API keys,” Google explained. For everyone else, sorry: It’s Antigravity CLI or bust, but don’t expect the same experience.“There won't be 1:1 feature parity right out of the gate” between Gemini CLI and Antigravity CLI, Google added.
