Our take
Written Sep 17, 2026Fugu Max is a hosted-only model from Sakana AI, so using it means choosing a host rather than running it yourself. It takes text, images and files in one request and can hold a long document whole, but nothing in our data measures how good its answers are.
Reach for it when a single request needs to carry text, images and files together, or when a long document can be sent whole instead of chunked. Both listed hosts charge the same rate, so the choice between them is not a price decision. Skip it if you need measured quality evidence before committing, or if you need to run the model on your own hardware.
The case for it
- A long document can go in whole rather than split up first, though reliable recall across all of it is unverified in our data.
- Text, images and files go into the same request, so a document and a screenshot do not have to be described in words first.
- Both listed hosts charge the same rate, so the host choice is not a price decision.
The case against it
- No benchmark scores are supplied, so any judgement of its answers needs a trial on work you can check yourself.
- We list no download for it, so using it means choosing a host and sending your data to one.
- No licence is supplied, so what you may do with its output is not established here.
How good is it?
We hold no score for this model.
So there is no figure here for everyday use, coding, agent work or writing. That is a gap in our data, not a low score.

What each host's API supports
