What each model is best at

Strengths shift with every release. Prism keeps the whole bench available so you never have to bet on one.

More than a chat window
Five things Prism does beyond sending a prompt. Scroll to stack through them.
Multi-model chat01 / 05
Ask once, judge every answer
One prompt fans out to every model you enable. Replies stream in side by side, so you compare rather than guess which one to trust.
Up to six models on one prompt
Collapse or focus any pane mid-thread
Generate a consensus from what came back
prism.app / compare
Web search02 / 05
Answers that show their sources
Search runs before the model answers, and every claim carries the page it came from — so you can check the work instead of taking it on faith.
Live results, not training data
Numbered citations inline
Open any source in one click
Image generation03 / 05
Generate images without a second subscription
Describe what you want, pick a model, aspect and count. Anything made in a chat lands in the same gallery as ImageLab work.
Several image models included
Variations and instruction-based edits
One gallery for chat and ImageLab

Reasoning effort04 / 05
Trade speed for depth, per model
Models that support it expose a reasoning dial. Run one deep on the hard part of a question and the rest shallow on the easy part.
Low, medium and high
Set independently on each pane
Only shown where the model supports it
Memory05 / 05
Context that carries between chats
Projects hold the files and standing instructions a body of work needs, and every chat started inside one inherits them.
Files and instructions per project
Extracted facts you can edit

VS
What people are saying
I stopped guessing which model to open. I ask all of them and take the one that actually answered the question.
Watching them disagree is the point. When three agree and one does not, that is when I go and check the source.
One invoice instead of five, and my team stopped expensing subscriptions I had no visibility on.
Paying in taka without an international card was the thing that finally made this usable for our whole studio.
I send the same brief to four models and the consensus is usually better than any single answer was.
The reasoning-effort control is underrated. One model thinking hard, three answering fast, in the same thread.
Why compare
One model is not enough
We labelled 2,400 answers from five frontier models against the same prompts. No single model was reliably right, and which one failed changed with the question.
61%Accurate
Complete and correct on first pass.
27%Incomplete
Right as far as it went, but missing something material.
12%Wrong
Confidently incorrect — the case comparison catches.
