Gemini CLI Version Tracker: Environment Variables, Models & Features#

Published on July 14, 2026

We analyze Google's Gemini CLI releases to document the environment variables, model IDs, and feature surface of each build. Because Gemini CLI is fully open source, every finding is grounded in the published source at the release tag and the tag-to-tag diff — commits, contributors, and the subsystems that moved — plus the official release notes.

Tracking the other agents too? See the Claude Code Version Tracker, Codex CLI Version Tracker, OpenCode Version Tracker, and Amp Version Tracker.
