Recorded price changes

• January 1, 2027 · price up 2.0×. Gemini 3.6, 3.7 and 3.8 Flash pricing is promotional until December 31, 2026. On January 1, 2027 it doubles: input from $0.75 to $1.50 and output from $3.75 to $7.50 per million tokens, the list prices Google shows next to the promotional ones. source
• September 30, 2026 · change of this site's criterion · reference price withdrawn. Change of this site's criterion, not a price change by Google. Gemini Omni Flash (gemini-omni-1.1-flash) and its preview endpoint (gemini-omni-flash-preview) entered this dataset in the hand sweep of September 16, 2026, priced $1.50 per million input tokens and $9.00 per million output tokens. On September 30, 2026 Google's model page for both versions was read: it describes a model 'for fast, conversational video generation and editing' and gives its supported output as 'Video' only. The pricing table covers models charged per token with text output, so both rows left the table, the calculator and the counts that day. The $9.00 (text) figure on Google's pricing page is labelled as including thinking tokens; it is not the price of a text answer comparable with the other rows. Both rows stay in the dataset with their prices and dates, and their pages remain online, out of the search index. source
• September 16, 2026 · added to this dataset, our omission: Gemini 2.5 Computer Use Preview, Gemini Robotics ER 2 Preview, Gemini Robotics ER 2 Streaming Preview, Gemini Omni Flash Preview. Full explanation

Outside the table: Gemini Omni Flash, Gemini Omni Flash Preview, priced per token but not with text output (2026-09-30).
