GPT vs DeepSeek: AI chat model comparison
This compares two chat models in the current Mixer AI knowledge base. Review available versions, image support and specialized modes, then test both on the same request instead of inventing one universal winner.
Key differences
Specifications
| Feature | GPT | DeepSeek |
|---|---|---|
| Versions | GPT 6 Astra / GPT 6 Luna / GPT 6 Sol / GPT 6.1 Sol / GPT 6.1 Terra / GPT 5.6 Sol / GPT 5.6 Terra / GPT 5.6 Luna | DeepSeek V4.1 Flash |
| Image analysis | Yes | No |
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 GPT
Turn a brief, notes and images into a draft, plan or clear set of decisions.
- GPT 6 Astra, GPT 6 Luna, GPT 6 Sol, GPT 6.1 Sol and the GPT 5.6 family are separate choices in Canvas.
- Connect up to 5 text blocks and 10 images. This tool produces text, not a new image.
- Canvas saves answers up to 3400 characters. Work on larger material in sections.
- The pre-request amount is an estimate; final billing uses actual usage. Answers can contain errors.
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.
What we compare
FAQ
How should I compare GPT 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.
