Holy crap, here's an initial review of Antigravity.
I just told Google's
@antigravity to rebuild my old school style html/css website in threejs using the same existing assets but with better UI/UX, and it is currently launching chrome browser and doing "testing".
When i try to muck around with it, the website it is working on locks the UI. it also pops up stuff to get my attention that something needs my permission.
Pros:
1) Ladies and gents, Gemini 3 is FREE to use right now if you use it via the Antigravity app:
antigravity.google. Recall it costs 4$ per question I ask it in previous post. Building this probably experimental website costed Google probably 12-15$ since each time it thought for over 10 minutes, and I gave it exactly 3 questions.
2) It does more stuff than just code, it runs python and local servers temporally while it is working - like a real agent. This feels next level.
3) Likely the most powerful model today. (I have yet to test Grok 4.1)
Cons:
1) For long files, it fails to read, saying the model's thing has reached its maximum output. (my html file is like only 1300 lines long). What it should do in this case is use a weaker model automatically for reading, like 2.5 Flash, but then compress the data back into Gemini 3 or something.
2) There is NO YOLO MODE. I have to be there and click confirm the whole time on the SAME shit while it was doing its thing for nearly an hour going back and fourth a few times. This limits it from being a autonomous agent but rather I have to micromanage this agent. I want to be able to walk off and catch some Pokémon take a leak while it do its thing. I have clicked on confirm or accept all at least a few dozen times in just 2 prompts.
3) Nested thinking is cool but it hides the actual time it takes to complete a task. It has been thinking the whole time I write this post(or essay) and nagging me to press confirm every other minute, which I have already complained in (2). Interweave thinking from MinimaxM2 and kimi k2 claims to be able to do 200-300 steps, the second task to improve the carousal made it use 38 thinking steps.
4) It suffers from the same issue as other models; it gets dumber as you do follow questions/fixes; probably due to context limit or weaker performance on higher context, since it starts to create issues (like errors). There has still yet to have a model/tool that can communicate to one another that the context is full or unusable, and we need to compress what we have done so far and start a new task with new context.
Thoughts:
This model is very capable in Antigravity but it nags the hell out of me - it is very annoying and I wish there was a yolo mode like
@charmcli provides - its the only true yolo mode; not even Roo or Kilo has true yolo as it nags you for each new command. What makes Antigravity aggravating is that it asks for the SAME commands used on even the same files. I understand that on first launch this feature is probably disabled for safety, since it can open servers and launch things outside of just coding (but Charm client can also do this these days). I am tempted to make a screenshot of every single annoying confirm/accept button it brought up, but I am limited to 4 screenshots per x post.
I also feel like this is similar to the time when ChatGPT Codex webui was free for a few months with unlimited usage, then when it gathered mass adoption you could only ask it like 5-10 questions a week with the 20$ a month plan, with intermittent throttling at random times where the model gets dumb as more users use it.
But take advantage while it lasts! If your website sucks or don't have one, might as well use it to build one for free!
It has built in things like error logs in UI form, and notifications are deliberately added on to the model and that is impressive on its own-but also feels somehow pre-trained, which I have mixed feelings about for some reason.
In the end, the long waits and constant nagging for me to click confirm/accept feels stressful and a lot like "work", but I don't have a doubt that a YOLO mode will be added in the future.
The ONLY down side I can think of having yolo mode on is when AI gets so smart that it will try to download itself to many computers to decentralize itself... well and maybe auto deleting your stuff or uploading things to some place.
As I am typing this, I have hit its "generous limits", which is 3 questions, but nonstop thinking.
Well, I didn't backup the work done by Gemini and it crapped out while it was thinking so now I have a non functioning website (the one in screenshot 1 is functioning, but I asked it to fix the overlapping issue).
I'm impressed but not impressed, know what I mean? After 3 questions, you gotta pay up. But I don't see how this can't be done with another model; it is fancy though, but if a dev know what they are doing, these bells and whistles are unnecessary.
Antigravity feels targeted towards people who don't know how to code at all - which is fine, but it will cost ya.
