How do I compare AI model answers side-by-side?

Open OmnyChat Compare, type your prompt once, and every selected model (GPT-6 Astra, Claude, Gemini and more) answers in parallel. You see all responses at the same time and can pick the one you trust.

Which AI models can I compare?

OmnyChat supports 120+ models including GPT-6 Astra, Claude Fable 5.1, Gemini 3.8 Flash, Grok 4.6, DeepSeek V4 Pro, Llama 4, Qwen3.8 Flash, and Kimi K3. Sign in to compare models; Pro unlocks the full catalog.

Why compare AI answers instead of just using one model?

Different models excel at different tasks: one may be better at code, another at writing tone, another at math. Comparing answers in parallel catches hallucinations faster and helps you learn which model to trust for each kind of question.

Is comparing AI models included in paid plans?

Yes. OmnyChat paid plans include AI model comparison. Pro unlocks 120+ models and up to four parallel comparisons.

AI Judge is an optional feature where a neutral third model reviews all the answers and picks the strongest one, surfacing why. Useful when you want a quick verdict without reading every reply.

Prompt

Teaching

“Explain closures to a junior dev in 2 sentences.”

GPT-6 Astra

Answer

A closure is a function that remembers variables from where it was defined, even after that outer scope has finished. It's how callbacks keep access to state without globals.

Claude Fable 5.1

Answer

Closures are functions that carry their birthplace with them — they keep a reference to the variables in the scope where they were created. That's why an event handler defined inside a function can still see that function's locals later.

Gemini 3.8 Flash

Answer

Think of a closure as a backpack: when a function is created, it packs up the surrounding variables and carries them wherever it goes — even after the outer function returns.

How it runs

One prompt. Multiple answers. No tab-hopping.

Different models are good at different things. Comparing catches hallucinations, exposes tone differences, and teaches you which model to reach for next time.

Step 01
Ask one prompt.
Code review, writing draft, fact-check, explainer — anything you'd normally ask one AI, send to the models you choose.
Step 02
Your selected models answer in parallel.
GPT-6 Astra, Claude Fable 5.1, Gemini 3.8 Flash reply at the same time. No more switching tabs or retyping.
Step 03
Pick the one you trust.
Read them side-by-side. Or let the AI Judge — a neutral fourth model — surface the strongest answer.

Why not just ChatGPT?

Because you already guessed the answer wasn't the best one.

Different models, different strengths.

Claude writes cleaner code. GPT nails tone. Gemini's faster at lookup. You want the best answer, not the same answer from one brand.

Catch hallucinations in seconds.

If three models agree, you've got a signal. If they disagree, you've got a question worth asking. One model alone can't tell you that.

Learn whose voice you prefer.

Over time you notice which model suits your taste for which task. That's a skill — and this page is how you build it.
