## What to compare in the answers

Give both models the same request and the same context. Compare instruction following, factual care, response structure, long-context handling, image analysis when available, and whether uncertainty is communicated usefully.

## 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.

## What to inspect with DeepSeek

DeepSeek: text models in Mixer AI Canvas. Versions: DeepSeek V4.1 Flash.

- Text in, text out, in Canvas.

- Version choice: DeepSeek V4.1 Flash.

- The cost of a reply depends on the length of the request and the reply; it is not fixed.

- This page describes the Mixer AI catalog, not answer quality: test the model on your own request.

## 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.

## FAQ

How should I compare Kimi and DeepSeek fairly?

Give both models the same request, context and attachments. Score accuracy, reasoning quality, response format and repeatability separately.

Are both models available in Mixer AI?

Yes. Both chat models are available in Canvas on Mixer AI; text model selection exists only there. The page exists only for models in the current catalog.

Which model is better?

There is no universal answer. First exclude a model that lacks a required capability, such as image analysis or the version you need, then compare both on your typical requests.
