LiteLLM adds Google's Gemini 4 Argon with launch pricing through Nov 30

LiteLLM announces support for Gemini 4 Argon, which it describes as Google's flagship reasoning model, and says launch pricing applies until Nov 30.

Google for Developers reposted the LiteLLM announcement on X on Oct 14, 2026.

The only sourced details are the support announcement, the "launch pricing" label, and the Nov 30 end date. The report does not give the price figures, so the pricing change cannot be quantified from it.
