From 9 October 2026 the Gemini free tier drops from three models to one. Free accounts keep Flash-Lite and lose Flash and Pro. Google AI Plus subscribers at $4.99 a month lose Pro as well, and AI Pro subscribers gain Deep Think, which until now was reserved for the $99.99 Ultra plan.
None of the models changed. What changed is which of them you are allowed to pick. That makes this a budget decision rather than a prompting one, and it lands three days from now.
The model picker shrinks, and it shrinks by plan. According to 9to5Google, which reported the in-app notice on 3 October, free users keep Flash-Lite 3.5 and lose Flash 3.6 and Pro 3.1. AI Plus keeps Flash-Lite and Flash. AI Pro and AI Ultra keep all three.
AI Pro gets something back in the same change: Deep Think, which Google describes as “maximum parallel reasoning” and which can take minutes to answer. That was an Ultra-only feature before 9 October.
Google has published no rationale for the restriction. There is also no indication that this is regional, and no subscriber numbers to tell you how many people it touches. If you want to know whether your own account is affected, the only reliable test is to open the model picker and count what is in it.
Six days before the free tier shrank, Google announced its most capable model and gave it to a handful of security teams. Gemini 4 Argon, announced on 30 September 2026, is described by Google as its “frontier model for real-world coding, enterprise knowledge work, and cyber defense”. It scores 77.9 percent on DeepSWE v1.1, 68 percent on CWE-bench v1 and 91.7 percent on LVBench.
The headline number is a 1 million token output limit, up from 64,000. That is an output limit, not a context window: it is the size of what the model can write in one go, not the size of what you can feed it. It matters when you want a full report in a single response, and not at all when you want to drop a year of campaign data into a chat.
Argon is rolling out “to a set of trusted cyber defenders through our Fairwind Program”, with a version that has no cyber guardrails for those teams and a guarded version for everyone else. Google says broader release starts with paid API customers and AI Ultra subscribers, and gives no date. Introductory API pricing is $2 per million input tokens and $10 per million output, rising to $4 and $20 afterwards. So the practical answer for a content operation is that Argon is not a tool you can plan around this quarter.
Flash-Lite is a working model, not a demo. It handles the volume work most marketers actually run through a chat window: rewriting a caption six ways, pulling the claims out of a press release, turning a transcript into bullet points, drafting a subject line set. The 32,000 token context window on the free plan is not changing, per 9to5Google.
What it will not do is the reasoning work people were quietly using Pro for. Long competitor comparisons, a brief that has to hold ten constraints at once, anything where you were pasting in a spreadsheet and asking for analysis: that is the capability leaving the free plan.
Google is also replacing Gems with skills, which are reusable instructions you build once and call later, and skills do not need a subscription. From 9 October the Gemini free tier will be running them on Flash-Lite. Google has published nothing about how a skill written against Pro behaves on the smaller model, so if you have built any, run them this week and keep the prompts somewhere outside the app.
The quieter part of the same change is an effort setting on every model you can still reach: low, medium and high. Google’s wording is that it will “increase the model’s ability to complete tasks and provide more thorough answers to queries, but will also use more of your limit”.
That limit is compute-based and it refreshes on a clock. Google’s support page says your limit “refreshes every 5 hours until you reach your weekly limit”, and sets the plans against each other as multipliers: AI Plus at twice standard limits, AI Pro at four times, Ultra at five or twenty times AI Pro depending on the subscription.
Google publishes multipliers, not counts. There is no number of prompts per day on any tier, so you cannot work out in advance what high effort costs you or when you will run out. You find out by hitting it.
The prices, as reported by Engadget on 6 October: AI Plus $4.99 a month, AI Pro $19.99, Ultra from $99.99. The decision that matters is between free and $4.99, and $4.99 buys back Flash, not Pro.
If Pro is what you were using, the comparison is $19.99 against what you already pay elsewhere. Anyone running ChatGPT Plus or Claude Pro already has a comparable reasoning model on a plan they are paying for, and a second subscription at the same price for the same job is hard to justify. If Gemini is your only paid AI tool, $19.99 is the number. If it is your third, this is a good week to cut it and compete with bigger brands on one stack you know well rather than three you half use.
Google has not said they will stop working, and skills do not require a paid plan. What changes is the model underneath them on a free account, which becomes Flash-Lite only. Treat a skill that depended on Pro-level reasoning as untested rather than broken, and check it yourself before the date.
Not as a consumer, not yet. Google says broader release starts with paid API customers and AI Ultra subscribers, and has given no date for either. Argon’s first users are cyber defenders in the Fairwind Program.
Google’s notice covers the consumer plans: free, AI Plus, AI Pro and AI Ultra. Nothing has been published about model access on work or school accounts, so if your agency runs on Workspace, verify it in your own admin console rather than assuming the consumer change applies.
For high-volume drafting, summarising and rewriting, yes. For multi-step analysis and long comparisons, it is a real step down from Pro. The test that settles it is sending Flash-Lite your own recurring tasks for a day rather than reading anyone’s benchmark.
The move this week is not choosing a plan. It is finding out which of your tasks genuinely needed Pro, because that list is shorter than most people expect, and it decides whether you owe Google $4.99, $19.99 or nothing.
