Gemini 4 Argon

GA

GA/stable ('Stable: gemini-4-argon' on the model page; the October 13, 2026 release note is headed 'Gemini 4 Argon (gemini-4-argon) generally available (GA)'), described by Google as 'our flagship reasoning model, built for complex software engineering, deep mathematical and scientific problem solving, autonomous multi-step agents, and long decode up to 1M tokens'. THE PRICE FIELDS CARRY THE INTRODUCTORY COLUMN IN FORCE THROUGH 2026-11-30, not the later one — Google's pricing page publishes a two-date schedule: paid-tier Standard is $2.00 in / $10.00 out per 1M (output including thinking tokens) with context caching $0.10/1M through November 30, 2026, doubling to $4.00 / $20.00 / $0.20 starting December 1, 2026; the 'What's new in Gemini 4 Argon' page calls the first column 'an introductory price'. A midnight boundary, so there is no intra-day error window; scripts/check-google-prices.mjs resolves the schedule against the system clock and will report the row as DRIFT on 2026-12-01 without anyone remembering. Other published tiers, none of which fit the per-MTok fields, on the same two dates: Batch and Flex $1.00 in / $5.00 out (caching $0.05) then $2.00 / $10.00 (caching $0.10); Priority $3.60 / $18.00 (caching $0.18) then $7.20 / $36.00 (caching $0.36). Caching is implicit only — Google states explicit caching is not supported, so no cache storage fee is published. Grounding with Google Search or Maps: 5,000 requests/month free shared across all Gemini 3 and newer models, then $14 per 1,000. Not available on the Free tier (every free-tier cell reads 'Not available') nor on the Google AI Pro plan. Spec table gives a 1,048,576-token context window that Google labels a 'unified input and output token limit', and max output 65,536 (default synchronous) / up to 1,048,576 with long decode — max_output_tokens carries the default synchronous figure. Inputs text/image/video/audio/PDF, output text; thinking supported at low, medium and high (default medium per the What's-new page); Live API, audio generation and image generation not supported, computer use supported in preview. Released 2026-10-13 per the API release notes; the model page's 'Latest update' field carries it more coarsely as 'October 2026'. Google publishes no knowledge cutoff on the model page, pricing page or release note, so that stays null. Google announces no deprecation or shutdown for it and names no model it replaces.

Gemini 4 Argon by Google costs $2 per 1M input tokens and $10 per 1M output tokens ($4/1M blended), with a 1.0M (1.048.576-token) context window. It is generally available (GA).
