A fixed source library feeds separate finance-reconciliation and legal-citation lanes, each with an independent checker and visible negative-finding return path; irreversible steps pause for human signoff, and a separate ledger shows the November 30 token-price change.

Summary: Google released Gemini 4 Argon for enterprise work and developers on October 13, describing long document synthesis, finance reconciliations, legal citations and guarded cybersecurity tasks. Its public model identifier is gemini-4-argon. Introductory API prices run through November 30 before doubling. Customer results and benchmark scores in the launch post are vendor reported, not independently verified.

Why it matters: Knowledge workers should evaluate one bounded reconciliation or legal-source task with fixed inputs, citation checks, explicit error handling and human signoff. Finance teams should model token costs under both introductory and later pricing before committing a workflow.
