Gemini 3.8 Flash
Analyze images and text together, from describing a frame to checking a brief.
Updated
When to choose it
Gemini 3.8 Flash and Gemini 3.1 Pro in Canvas help compare visual material with text in one task. Review frames against a clear rubric, build a scene description or find gaps between a layout and its requirements. Distinguish what the sources show from what you want proposed as a new idea.
- Compare images and text blocks within one request.
- Two family variants let you compare answers and prices on the same task.
Modes and settings
- Gemini 3.8 Flash and Gemini 3.1 Pro are available in Canvas text tools.
- Up to 5 text blocks and 10 images. Capabilities in other Gemini interfaces do not change this tool's inputs.

Rates are in coins per million tokens, not per reply. A token is a piece of text, not necessarily a word. Input and output have separate rates. Canvas reserves an estimate and settles from actual usage; images also affect usage.
≈ marks a fractional rate rounded to two decimal places for display; billing uses full precision.
In US dollars: from ≈ $0.338 per 1M input tokens. 1 coin ≈ $0.011.
What you can make
- Review a set of frames for composition, legibility and fit with the brief.
- Prepare a description or prompt from several references.
How to direct the result
- Number the images and give comparison criteria rather than asking for the prettiest one.
- Separate observations, mismatches and concrete suggestions.
Example: review an advertising image series
Compare the connected images against the written brief. For each frame, check product placement, room for a headline and consistency of package color and shape. Describe only what is visible. Flag details too small to judge. Then suggest one concrete edit per frame. Stay under 2500 characters.
What to keep in mind
- Canvas answers are limited to 3400 characters. Split a larger analysis into parts.
- Small lettering and image numbers can be misread; do not use the answer as the only check.

Guides and comparisons using this model
FAQ
Should I choose Flash or Pro?
Compare tariffs and begin with a short task. Test both versions for more complex comparisons involving several constraints.
Can I connect ten pictures?
Yes, but include only useful ones. Give each a number and clear role.
Will it create an image after the analysis?
This tool returns text. Pass the resulting description to an image model for generation.
Can I attach audio or video?
The Canvas text tool described here uses text and images. Do not assume it shares every input of other Gemini products.
How do I check small packaging text?
Supply a clear enlarged crop and compare the answer with the original. A wide shot may not be enough.
Why are input and output priced separately?
Processing source material and generating text have different rates. Final billing depends on actual usage, not a fixed fee per message.
What changes the price?
It depends on the version, the text and images supplied, and the response length. Canvas reserves an estimate first, then bills actual usage. The rates in the table help compare versions; they are not a fixed price for every reply.
Do I need a separate model subscription?
No. In Mixer AI, you top up one coin balance and use it for the tasks you need. You do not need a separate subscription to this model.
