The same guidance states that turning off automatic model selection makes the app use Flash-Lite for all responses. Usage environment Confirmed information What to check separately Google Search Hydrogen is available to all users worldwide Conditions for selecting Hydrogen for each question Automatic model selection in the Gemini app Hydrogen may be used for questions that require more reasoning Model selection settings applied to the current account Automatic model selection turned off in the Gemini app The guidance states that Flash-Lite is used for all responses Separate from model selection conditions in Search There is no basis for applying the app's explanation of automatic model selection directly to Search. The conditions under which Search calls Hydrogen have not been disclosed. API eligibility and detailed usage conditions in Korea must also be checked in separate documentation. Model pricing is public, but Search usage limits are not Google's announced model pricing treats input and output separately. Input is the content sent to the model, and output is the content the model generates. Tokens are the units used to process this content and calculate charges. Item Terms announced by Google Input price $1.50 per 1 million input tokens Output price $7.50 per 1 million output tokens Context window 1 million tokens Pricing across the context window The same throughout the entire context window This pricing was provided in the model introduction announcement on November 12, 2026. Context is the amount of information the model can handle at one time. The context limit and the amount that can be used per day are different measures. These token prices should not be interpreted as fees for ordinary Search use. The verified pricing text does not specify a per-search charge. Daily usage limits for Hydrogen in Search have not been disclosed either. Performance scores are independent measurements by Artificial Analysis Artificial Analysis is the organization behind the verified Intelligence Index scores. High and Xhigh are separate evaluation entries. The scores were not presented as direct measurements of response quality in Google Search itself. Evaluation target Artificial Analysis Intelligence Index Measured by Gemini 4 Hydrogen High 51 points Artificial Analysis Gemini 4 Hydrogen Xhigh 54 points Artificial Analysis The scores appear on the High evaluation page and the Xhigh evaluation page, respectively. Google's description of changes to Search features should be read separately from the external evaluation scores. Which evaluation configuration applies to Search has not been confirmed. The release time and extent of existing model replacement are undisclosed The announcement alone does not establish the detailed scope of Hydrogen's deployment in Search. The statement that it is available worldwide does not establish that every search request uses the same model. The following items were not confirmed in the official announcement. The exact release time and time zone The specific model selection conditions for using Hydrogen in Search Daily usage limits for Hydrogen in Search Whether it has completely replaced the existing search models The announcement date is confirmed as November 12, 2026. Without an exact time and time zone, it cannot be converted to Korean time. The time when the announcement was detected in a feed must also be distinguished from the actual release time. In Korea, check the AI Mode display and what the pricing applies to To use it in Korea, first check whether AI Mode appears on the search screen. The Google Search Help Center explains how to enter a question in the search box and then select AI Mode. This access path alone does not identify the model used for an individual response. Open Google Search. Enter a question in the search box. Select AI Mode on the search screen. Detailed support conditions for Korea and the Korean language must be checked in the Search Help Center. If you use the Gemini app, check the app's automatic model selection settings separately. When checking costs, distinguish between the terms of Search use and token-based model pricing. FAQ Q.
