2026-10-24-gemini-cli-the-readme-stops-promising-obsolete-access-and-warns-about-gemini-4-optimization
The README stops promising obsolete access and warns about Gemini 4 optimization. Google’s README now says Gemini CLI is not optimized for Gemini 4 Argon and recommends Antigravity for current models. It removes obsolete free-access selling points and states that consumer Google-login access was replaced on 2026-06-18. The stable branch’s older authentication guide still recommends consumer Google sign-in. The new pinned README is a receipt for Google’s October statement; it does not establish the historical bytes of a service notice at the previous cutoff or a universal shutdown of API-key/Vertex access.
Channel: docs-only. Half: both. Date: 2026-10-16.
Operator consequence: Separate choosing a harness version from verifying an account’s service entitlement. Do not promote Gemini 4 launch benchmarks into Gemini CLI performance, or treat an installable npm package as a service guarantee. For migration planning, verify the actual authentication route and export/import requirements before allocating operator time to repairing an intentionally unavailable login path.
