What it costs inside Whizi
Whizi meters messages in credits rather than tokens, and Gemini 3.6 Flash is charged at 3 credits per message. The cost does not change with the length of your message or the length of the answer, so a one line question and a long document analysis cost the same.
| Plan | Price per month | Monthly credits | Messages on this model |
|---|---|---|---|
| Pro | $29.99, or $19.99 billed yearly | 2,000 | 666 |
| Powerhouse | $49.99, or $34.99 billed yearly | 8,000 | 2,666 |
Gemini 3.6 Flash is included from the Pro plan up. Pro is a curated tier rather than everything cheap: one or two current flagships per model family, each fast tier, and the high volume workhorses. See plans and limits.

The context window in practice
Gemini 3.6 Flash accepts 1M tokens of context, which is roughly 1600 pages of text. That is well above the median for the priced catalogue.
Advertised context and usable context are not the same thing. Recall tends to degrade before the stated limit is reached, particularly for material in the middle of a long input, so the practical test is to upload a long document and ask about something buried halfway through rather than trusting the number.
The number matters most when you are working from your own files. If a document is too long for the model you picked, switching to a larger-context model in the same conversation carries the thread across, so you are not starting over. See switching models mid-conversation.

Frequently asked questions
How much does Gemini 3.6 Flash cost?
$1.5 per million input tokens and $7.5 per million output tokens at list rates, which works out to $0.0053 for one standard answer of 1,000 tokens in and 500 out, or $5.25 for a thousand of them. Inside Whizi it is 3 credits per message on a monthly allowance, rather than metered per token.
Which Whizi plan includes Gemini 3.6 Flash?
Pro and above, which is $29.99 per month or $19.99 billed yearly. At 3 credits per message, a Pro allowance of 2,000 credits covers 666 messages on this model if you spend the whole allowance here, and most people mix in a 1 credit model for routine work so it goes further.
What is the context window of Gemini 3.6 Flash?
1M tokens, which is roughly 1600 pages of text and sits well above the median for the priced catalogue. Treat that as the ceiling rather than the working figure: recall usually degrades before the stated limit, especially for content in the middle of a long input.
Is Gemini 3.6 Flash expensive compared to other models?
It ranks 71 of 89 priced models by cost per answer, so 18 cost more and 70 cost less. The spread across the whole catalogue is about 4800 times from cheapest to priciest, which is far wider than most people assume, so "expensive" only means anything relative to the specific alternative you would otherwise use.
