## What to compare in the answers

## What to inspect with Gemini 3.8 Flash

Analyze images and text together, from describing a frame to checking a brief.

- 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.

- 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.

## What to inspect with Kimi

Kimi K3 and K3.1 Pro chat models: a long context, with text and images as input.

- Kimi K3 and Kimi K3.1 Pro are separate choices in Canvas.

- Up to 5 text blocks and 10 images per task, producing a text answer.

- Canvas saves up to 3400 answer characters: build a long result in parts.

- A confident answer can be wrong: check figures, dates, quotations and outside facts.

## How to run a fair comparison

- Use the same system context and user request for both models.

- For image tests, attach the same file and ask the same question about it.

- Score reasoning quality, factual accuracy, response format and speed separately.

- Repeat difficult tests: one good answer does not prove consistent model behavior.

## Sources

Prices, availability and specifications come from the Mixer AI catalog. This is not an independent test: try both models on the same task before choosing.
