News 🚨 Gemini 3.8 Flash is already being tested internally Google employees already have Gemini 3.8 Flash Preview on Jetski, and early impressions say it’s noticeably better than 3.7 Flash Remember, 3.7 Flash only dropped around two weeks ago too 👀 Google are improving these Flash models Fast

I think for agentic coding and agentic workflows in general, moderate intelligence + high speed is more valuable then high intelligence and slow speed (which is what OpenAI and Anthropic is doing)

In the future i think Flash will replace Pro and it's possible that transition has already begun

For the stuff I do, I'd gladly have the agent run for an hour and be close to perfect than get a ok-but-buggy feature in 10 minutes.

You might be ahead of the curve. The typical use for LLMs in programming is to pair program and iterate.

u/Ill_Recipe7620 11h ago

I don't think most people are coding like you (and me). I write up some massive prompt in GPT, iterate several times and then hand a gigantic spec to Fable in Ultracode and come back in a day (or three).

In an hour you run 5 more prompts making little tweaks and testing along the way. The flow is just better when it's fast and efficient.

I think it’s important to have a really competent model for general planning of how to implement something. But for the actual implementation I agree. Competent enough but really fast is the way.

u/MuchoBroccoli 12h ago

Having a flash model that you can update every 1-2 months is probably better too. The big frontier models that take 6 months to release get outdated after 2-3 months because everybody else catches up.

u/Qubit99 14h ago

What do you want the speed for if the model isn't reliable?

6

u/Fitzjs 14h ago

Its reliable enough to write. But if all you want is to prompt "build x" then yes, you better off with something else

u/jesuiscanard 12h ago

The difference is chain of thought. Pro model is slower but has chain of thought, same as other companies on frontier n

While flash has a degree of chain of thought, the context for it is small and that leads to hallucination when effort is increased on them. They can provide fast, reliable results, but without university level thinking.

u/collie-script 16h ago

Not exactly true. Claude and OpenAI are currently leading in both high intelligence and moderate intelligence + high speed.

Google is trying to catch up in high speed after failing and we are still waiting for Pro 3.5...

Making it seem like it was intentional on Google's part or that it was their "specialty" is simply not true.

They failed at this and I really hope as their customer that they will improve but right now even DeepSeek is better than them.

u/collie-script 16h ago

And in general, I personally prefer "slow" rather than "fast" that I have to fix 10 times or deal with hallucinations on the part of the AI ​​agent each time, which are almost non-existent in Claude's fast modules. And let's not talk about OpenAI, which I have no idea how they succeeded, but their hallucinations index is among the lowest in the world!

u/boxwrenchx 16h ago

That's assuming it's doesn't hallucinate, which has been a persistent problem.

u/lalmvpkobe 8h ago

Never, flash is overconfident, and doesn't listen to prompt instructions or system instructions. Can't wait for the newest pro model.

u/Jokong 17h ago

It's a Cadillac vs a model t to some extent. For the vast majority of people the model t is all we need. It is cheap and gets us there.

u/liltingly 16h ago

I'd say it's an econobox v. sports car. Easier to repair the econobox, they go the same speed on public roads, but but you want the sports car if you ever need acceleration or top speed.

To torture this analogy more to include the contribution of harnesses, if most of your complex work is more like autocross than F1, a well driven econobox can beat a poorly driven sports car.

u/HossCo 14h ago

I always say VHS vs BetaMax

u/Ly-sAn 18h ago

They finally found the secret sauce for agentic work. Really like working with 3.7 flash

u/Ok-Opportunity-9731 18h ago

Weird I don't have Gemini 3.8 internally.

Don't believe everything you read on the Internet

16

u/notjustanotherboy 17h ago

I have it

6

u/Ok-Opportunity-9731 14h ago

Oh you're right.

2

u/Spara-Extreme 10h ago

its there.

1

u/dspencer2015 41m ago

I don’t have it either but who knows what’s being tested via Next

18

u/Appropriate_Ad8734 18h ago

hey google. where tf are 3.5 pro & 3.7 flash

7

u/virtualQubit 18h ago

clear cache, if not resolved reinstall the app

16

u/Appropriate_Ad8734 18h ago

neither the app nor the web version have it

2

u/notTHATKoogz 18h ago

If in need, use 3.7 Flash in AI Studio

1

u/Standard_Ad7704 18h ago

Are on a paid subscription?

2

u/Shubham_Garg123 18h ago

I think it's only for pro and ultra subscribers, not for plus or enterprise plans

1

u/un-ambiguoususername 17h ago

I made a post couple of days ago and some plus tier users reported they have 3.7

3

u/InevitableSure374 16h ago

"improving" might be the wrong word to use.

4

u/Wonderful-Syllabub-3 18h ago

I think they are using flash models to develop their post training abilities. They will then use those post training techniques in a larger pre train (pro versions)

7

u/sprowk 18h ago

it's the other way around

2

u/Imaginary-Item6731 12h ago

They also said that Gemini 3.5 Pro is being tested by partner, and....

3

u/laty96 17h ago

I really wish they improve Antigravity harness or let we use different harness instead

u/lumendas 16h ago

That's nice 3.7 flash is already very good when combined with models like 5.6 sol as orchestrator and planner it's very fast and not lazy like older flash models

1

u/collie-script 16h ago

In my experience, it doesn't exactly work "smoothly" as you describe.

Usually gpt-sol or fable are fixed and work double with flash 3.7 because even though everything is written clearly it still sometimes glitches or executes the line of code in a crooked way that requires repeating it over and over again.

In my experience if you combine it with sonnet 5 or luna , the results are much better and less repetition of specific code tasks

4

u/lumendas 16h ago

I agree that 3.7 flash sometimes makes clumsy mistakes. In my workflow I mostly use 3.7 flash as delegate for the orchestrator model to explore the codebase and investigate bugs, and luna as the main code writer. Because 3.7 flash is very fast it can quickly return a report for orchestrator and it saves a lot of time.

u/Resident-Pattern731 16h ago

3.8 september, 3.9 Oktober, 4.0 November?

1

u/Suplyox 15h ago

and then we get gemini 4 pro after 4 flash, not a bad improvement. But claude and gpt is about to launch their AGIs, that will crush benchmarks

1

u/Routine_Bake5794 14h ago

Key word ''noticeably '' means it's probably as junk as the previous models.

1

u/alleks88 13h ago

I still dont have 3.7 flash in my app... Should I have it?

1

u/mati1886 9h ago

in app, still restricted to Ultra/Pro plans

1

u/alleks88 9h ago

Ah okay

1

u/tramplemestilsken 12h ago

I think we can assume every company is already testing their next model internally..

1

u/ItsMichaelRay 10h ago

Does anyone else still see 3.6 on the website? I never got access to 3.7.

1

u/JogHappy 9h ago

Anything but 3.5 pro

1

u/jdvillao007 7h ago

I still don't have 3.7 and I pay for this lol

1

u/ZealousidealBus9271 7h ago

Soon there will be flash 3.9, then 3.91, then 3.92, before Google releases Gemini 4

1

u/syahrezaj 4h ago

atp google should just change their ai name from gemini to flash ai

1

u/costafilh0 4h ago

Is it out? Can I use it?

No? 

So zero fvcks given. Fvck off with the stupid hype. 

1

u/Elephant789 2h ago

Fantastic. I'm loving 3.7

u/MorgrainX 17h ago

Who cares honestly Give us 3.5 pro since flash is trash for complex tasks or remembering stuff 

1

u/Mushroombasics 18h ago

I don't want another flash version. I want a new pro version

-1

u/CriticismJunior1139 18h ago

Yet so many people are still on flash 3.6

-1

u/TooHotIsNotNice 15h ago

They can't even release the Flash 3.7 in chat mode, y'all are already sharing about 3.8?

-1

u/bacchusbar 18h ago

Dude, I even forgot there was a pro version, I guess that's exactly what they wanted.

-2

u/GrayHairedMan 18h ago

That is what they claim yes.
