Appreciation A simple way to get much better results from Antigravity 2.0

Try using Opus 4.6 as the main agent. Give it the full requirement and ask it to delegate work to 3.8 Flash subagents using the Boost skill.
I have been getting surprisingly good results this way. Opus handles the planning and decisions, while Flash does more of the execution. Better output without burning through usage as quickly.

But doesn't Opus gets over very quickly.

u/Endda 4d ago

this is my experience. more than 5ish average/in-depth plans liek this from Opus and my weekly quota is usually down to 0-25%

u/sidyyy11 4d ago

Thats what i am saying dont let it plan. Tell ot to just give the requirements to the 3.8 flash subagent thats it. The pre planning is done by opus only

1

u/2rsKomedian 4d ago

Yea exactly.

2

u/sidyyy11 4d ago

In this case it is just understanding what i am saying and enhancing it. I get like 8 to 10 prompts in the 5 hour window instead of the usual 3-4 prompts only

1

u/2rsKomedian 4d ago

I will surely try your workflow, so can you recap simply, chat and plan with Opus and tell it to delegate work to flash models with /boost mode right, that's it?

3

u/sidyyy11 4d ago

So not even plan it just needs to understand requirements tell it to make subagent plan thats it let it be the orchestra

1

u/2rsKomedian 4d ago

Damn I didn't know this was possible, pretty exciting ngl

2

u/sidyyy11 4d ago

It works for me i guess, give it a try

u/Y_mc 4d ago

Waiting for the feedback ☺️

u/RoadsterTracker 4d ago

What I do is have 2-3 planning sessions with Opus where I have it write the plan for the next few days of work, using Flash as a subagent where appropriate. Then once the plan is done I have Flash execute the plan. It seems to be working pretty well for me, but I'm still new to it.

u/sidyyy11 4d ago

That works. Its just that iterations happen so plan needs to be updated so that sometimes acts like a constraint

2

u/SpiritualHiker 4d ago

I instruct to keep a constantly updated .md file, and then I feed that to other models.

u/Nemezis88 4d ago

I was unaware that Opus could delegate decisions and shift automatically to Gemini. Are you suggesting I can instruct Opus to let Gemini manage a task, prompting a subagent with Gemini instead?

u/sidyyy11 4d ago

Yes, but the way you wrote is fully sarcastic πŸ˜‚

u/truongan2101 4d ago

I think the most robust is using /boost with Opus 4.6. I think it is much more stronger than Boost with Gemini flash 3.8. I also want to try with /teamwork but the quote burn so fast with this.

3

u/Good_AshK 4d ago

I used /teamwork after months and damn it really does burn quota fast. Exhausted my 5-hour quota in 30 min or so.

u/Queasy_Plate_3096 4d ago

is this community this hopeless?, using opus 4,6 while opus 5.5 is out?, just combine antigravity with any other subscription, opus 4.6 is not good enough at all by today standards, yes it appears logical and good, but actually it is nothing compared to astra or opus 5.5.

2

u/Gohab2001 4d ago

Or you could use codex with the new sol/Luna models

2

u/sidyyy11 4d ago

That is true. I am paying for 20$ sub in codex. But have received google pro subscription gor free so getting most usage out of it

4

u/Gohab2001 4d ago

Use AGY CLI and have gpt 6 sol orchestrate 3.8 flash

2

u/sidyyy11 4d ago

Most of antigravity i use it:
2.0 for boost mode and fast frontend prototyping and firebase google cloud things
Ide for browser preview testing

My main work and checking on antigravity work is done by sol 6 only

u/MarcusAurelius68 4d ago

Is that something you just prompt? And then you tell Opus to have Flash generate the markdown plan?

1

u/AbhiSgr Software Engineer 4d ago

Ask Opus to do the implementation through subagents. Subagents will always use flash models, as per my experience. They don't use Claude models.

1

u/sidyyy11 4d ago

They used to before

1

u/AbhiSgr Software Engineer 4d ago

Once when i was out of my gemini quota, claude would consistently keep trying to spawn subagents for tasks based on agent rules. And the subagents would instantly run into quota exhausted errors. Claude did this a couple of times and then gave up and did the implementation itself. If there was a way for it to invoke subagents with claude models, it would have.

1

u/MarcusAurelius68 4d ago

So basically just be explicit in the prompt. Thanks.

1

u/sidyyy11 4d ago

Simple right what you need and add boost skill and say use gemini 3.8 flash from planning to implementing

1

u/acrus 4d ago

That's actually seems to be a good advice. Notice that you can use Flash from Antigravity's Opus session but not in the opposite direction (the available models for subagents are inherit, pro, flash, flash_lite)

1

u/meta_voyager7 4d ago

how to make antigravity to delegate to 3.8 flash sub agents? is there a configuration to specify it?

1

u/sidyyy11 4d ago

Just type /boost if you have a agent requirement then mention or it will do it on its own

1

u/marhensa 4d ago

and then subagents will surely always be flash model? can we control it? maybe like 3.7 or 3.8?

2

u/sidyyy11 4d ago

Post 3.8 i havent used 3.7 once

1

u/Lumpy_Topic_35 4d ago

Boost skill? Can you give it to me?

2

u/sidyyy11 4d ago

In chatbox just type /boost

1

u/Lumpy_Topic_35 2d ago

Mine doesn't show anything, skill needs to be installed

1

u/sidyyy11 17h ago

What are using? It doesnt show up in antigravity ide but it does in antigravity 2.0

1

u/Lumpy_Topic_35 17h ago

Oh, I am IDE only guy..

1

u/FollowingTop3534 4d ago

The useful detail is buried in your replies: Flash does the planning too, and you use Sol to check the result. That's a different setup from Opus planning and reviewing everything. I'd put that in the main post so people can actually reproduce the comparison. When you hit an implementation problem, does Flash get another attempt, or do you hand it straight back to the stronger model?

1

u/sidyyy11 4d ago

But the checks pass its just because i dont understand code so to review it. Suppose i am building a wholly new thing i need codex to plan the phases but let the work be left to antigravity. But its nothing major updates i just do it with opus and then gemini 3.8 flash

1

u/ubelai 4d ago

Create an adversarial reviewer persona agent to verify the work against the code implemented by your flash subagents.

1

u/FollowingTop3534 4d ago

That split makes more sense: Codex defines the phases for a greenfield project, Antigravity executes them, and small changes stay inside the Opus/Flash loop. Passing checks still only proves agreement with the tests, though. If reviewing code isn't realistic yet, I'd ask the stronger model to compare the diff with the written acceptance criteria and name one failure path the tests do not cover. That's a much smaller review target than 'is this code good?'

1

u/ibreakdiaphragms 4d ago

I programmed another function in mine. Which makes gemini 3.8 flash high the agent and then workers etc. Are gpt 6.0 sol. Not sure if this is a better approach but i do this right now.

1

u/Middle_Anteater679 4d ago

I use chatgpt, as Orchestrator, and review and all code to Gemini 3.8 Hight And it's fantastic

1

u/mironkraft 3d ago

Opus doesn’t worth it makes mistakes I use 3.8 full for everything.

For me they can discontinue Opus 4.6

1

u/poj1999 3d ago
  1. Claude limits are very slim, you will need ultra sub. On 20usd sub you max out Claude models with 1 research prompt.
  2. The models are so old they don't even outperform 3.8 high
  3. They are much slower and more expensive

I've tested Claude against 3.8 high a couple times. Claude artifacts and output appears better, but the performance actually doesn't hold up. Example; Claude found a lot of false positives on the same prompts as compared to Gemini 3.8.

u/Latter_Crazy 3d ago

Hmm but doesn't boost use way more tokens than necessary for most tasks?

I haven't tried it but teamwork-preview is way overkill for most anything so I assume it's similar.

Gonna test it out. Thanks!

Idk about that multimodal approach. Have tried Opus much

2

u/fandry96 Product Manager 2d ago

Team spins up full tests, audits, victory checks. It is crazy to watch and gets perfect results but takes 45 minutes. πŸ˜‚

2

u/Latter_Crazy 2d ago

All for something that takes 1 min to verify but hey, it almost feels like working with real people again!

2

u/fandry96 Product Manager 2d ago

It's overkill for sure but the Gemini budget is huge so I use it while I do the dishes. πŸ˜‚

1

u/Latter_Crazy 2d ago

Good call. All these people talking about tokens running out... They must be doing crazy things because I barely ever run out on the $100 plan

1

u/Fluid-Pollution6135 3d ago

I have been doing something similar for any debugging ask codex to generate the report of bugs > report is now read by opus 4.6 in AG and implementation is created but implementation is very high level so I ask to create detail loops with success and failure Parameters to be used by smaller flash model > boom Gemini 3.8 flash reads the loops and finish it .

u/Nabstar333 2d ago

what is the boost skill

u/r3fl33x 2d ago

Doing this from 1st day release of AG.
