What Google announced

Each point is from Google's own announcement unless its source says otherwise; the numbers link to the sources below.

  1. Google's footnote: the introductory price expires on December 31, 2026, and from January 1, 2027 Gemini 3.8 Flash costs $1.50 per million input tokens and $7.50 per million output tokens.[1][2]

  2. Google's price list counts thinking tokens in the output price, so a reply that reasons at length pays the output rate for that reasoning too.[2]

  3. The introductory price is the same as Gemini 3.7 Flash's, which Google released three weeks before 3.8 Flash.[1]

  4. Google calls 3.8 Flash its most intelligent workhorse model, with gains over 3.7 Flash in software engineering, agentic tasks and multi-step reasoning.[1]

  5. Google notes that 3.8 Flash can use more tokens on complex tasks, especially at higher effort levels, and keeps Gemini 3.7 Flash supported for work where efficiency comes first.[1]

  6. In Google's own apps, 3.8 Flash is for Google AI Pro and Ultra subscribers, in the Gemini app, AI Mode in Search and Gemini in Google Sheets.[1]

  7. A sibling model, Gemini 3.8 Flash Cyber, is only for vetted security teams, through Google's Fairwind Program.[1]

Gemini 3.8 Flash

Gemini 3.8 Flash has been in llmwise since September 23, 2026. llmwise's catalog prices it at $0.75 per million tokens in and $3.75 out (Google's list price; an introductory price, through December 31, 2026). But a Gemini 3.8 Flash message isn't billed by the token: the table below has its count on every plan.

Gemini 3.8 Flash on every llmwise plan
PlanGemini 3.8 Flash
Free ($0)Not in the trial
Plus ($10)Up to 125 a month, about $0.08 each
Pro ($20)Up to 250 a month, about $0.08 each
Max ($50)Up to 800 a month, about $0.06 each
Ultra ($100)Up to 1,800 a month, about $0.06 each
Studio ($200)Up to 4,000 a month, about $0.05 each

A paid plan's month is one allowance the models share. So a monthly count is the most you get if the month goes to that model, and “each” is the plan's price divided by it. Every message's price is shown before you send it. Every plan.

The counts above come with each plan's fair-use limit, in AI cost a month: Plus's is $3.75, Pro's $7.50, Max's $20, Ultra's $42, Studio's $85. That leaves room for every message at typical sizes, less if messages run very long or research-heavy. Every limit, explained.
