Gemini 4 Pro vs Gemini 3.8 Flash apparently gemini 3.8 flash is being routed to the new gemini pro inside Arena here's a side by side comparison of both 3.8 flash and the new gemini pro mode with both generated using the same prompt have a look, what do... you think?show more

that Gemini 4 Pro UI elements looks same as gemini 3.8 flash i think its still 3.8 flash

both are of same family so it's possible but since both are also one shot output i won't say it's the same 3.8 flash

@HarshithLucky3 Could be 3.9 flash 👀

@HarshithLucky3 with same prompt under same harness with one shot output taking similar time to generate 👀

Is it coming?

it's AGI lmao

You tried to be good at Gemini but its still not a good model

This might be a checkpoint which is currently being tested before launch

Ohh ok. I had wondered

Gemini 4 Pro looks good

big improvement against 3.8 flash

Ui i shit

what can you expect from Gemini

The prompter is more serious than the model

Is Gemini 4 Pro really coming out?

that's what it's being rumored

Yes from past 2 days, and it's slow as hell. I asked it to add a breadcrumb to the sidebar, and it took 20 min, read the entire repo and blah, blah... and then added it at the end

prompt?

here' create a 3d paper plan flying simulator using three.js, keep the terrain highly detailed

flash nasıl daha iyi olabiliyor

i don't think flash is better here against this Gemini Pro model

That’s the key caveat: if Arena is routing 3.8 Flash to a newer Pro backend, the comparison isn’t really Flash vs Pro-it’s Flash-as-Pro vs whatever the public Pro endpoint exposes. I’d want the exact model IDs, latency, and whether the prompt was run multiple times at the same temperature, otherwise the side-by-side could be measuring routing luck more than model quality.

More like 3.9 flash

Gemini 4 pro is agi

Flash built a cute paper-plane screensaver. Pro built a flight sim that wants my credit card for DLC hangars. If Arena is secretly serving Pro behind the Flash label, that would explain why my “cheap and fast” runs lately feel suspiciously cinematic.

I have a feeling this is Gemini 3.9 flash for some reason

let me cook new demos

Finall look like chatgpt 5.4 pro good

Lmao

what a huge difference bro gemini is about to cook

太牛了 期待

What's the speed of token gen how many turn used

Nice one

Well why can't it be gemini 3.8 flsh enhancements, how are people sure about Gemini 4 pro I am confused 🤔

It's the same garbage

does the api match this output because arena routing makes the comparison inconclusive

I hate how even after 1 year they havent fixed the HUD slop

@_Yamnaya_ so gemini is alive

really？

Can you share your prompt

Is is open to use ? It seems it is not yet released but how can you use it ?

Meh

I think it's not bad, the only thing is the UI is awful.

I waiting for Gemini 4.5 Pro
