Chapters19
The video discusses Google IO happenings before the new flagship model reveal, focusing on the announcements that came prior to the main flagship release.
Gemini 3.5 Flash inside Antigravity 2.0 goes free and insanely fast for coding—watch a live test building a site in minutes.
Summary
Income stream surfers’ host dives into Google IO’s early announcements, spotlighting Gemini 3.5 Flash and Anti-gravity 2.0. He emphasizes how Gemini 3.5 Flash is a major upgrade for speed and intelligence, claiming 300 tokens per second and noting an OS-like demo they built for $1,000. The video also covers Anti-gravity 2.0 going live globally and becoming free to use, with Gemini 3.5 Flash integrated. He recalls how Gemini 3 Flash inside Anti-gravity previously delivered strong multimodal capabilities at zero cost and explains why this free access could narrow the AI performance gap against top models. A hands-on test with Astro Builder Skill shows quick setup via a GitHub repo, running commands in a terminal, and generating a plumber website in Acton, with images and a basic service page. He critiques the result for its SEO gaps (no separate pages per service, no sitemap yet) but still lauds the speed and the “crazy fast” workflow. He compares free access to Claude and GPT-based offerings, suggests this is the best free option today for building, and hints at even more model drops (Gemini 3.5 Pro, Gemini Spark) in the near future. The video closes with a plug for Harbor SEO.ai (powered by Gemini) and a teaser about continuing coverage if access holds up.
Key Takeaways
- Gemini 3.5 Flash delivers around 300 tokens per second, marking a substantial speed boost over prior generations.
- Anti-gravity 2.0 is now globally available and free to use, with Gemini 3.5 Flash inside coming soon.
- A hands-on Astro Builder Skill demo shows how quickly a plumber website can be scaffolded using anti-gravity and Gemini 3.5 Flash.
- The quick-build result lacks SEO depth (no multi-page per service or sitemap) but demonstrates near-instant code and site generation capabilities.
- Open competition context: Opus 4.7 by Anthropic remains top-ranked, with OpenAI pricing patterns shaping expectations for free vs paid usage.
- The creator hints at Gemini 3.5 Pro and Gemini Spark as next releases, signaling ongoing expansion of Google’s AI tooling.
- A practical takeaway is to start projects inside Anti-gravity now to leverage free Gemini 3.5 Flash access.”],

Okay guys, so I'm going to break down everything that's happened at the Google IO so far. This video is before they announced their new flagship model. This video is more about the kind of things that they announced before the new flagship model. Let's just jump into things. Okay guys, so if you weren't watching the Google IO, then it's happening right now. And the main thing that they have announced so far is Gemini 3.5 Flash. Now for me personally, this is absolutely massive. I've been saying that I wanted a new Gemini flash model for ages, right?
I've been using or I did use for a very, very long time Gemini 3 flash inside anti-gravity and it was probably the best experience I've ever had with Google AI systems. So, this is what they've released. It's an incredibly fast new model. I was pretty excited about this. As you can see, I have been waiting for this specifically and I've been I've said this a million times. I really, really wanted a new Gemini Flash model. That's what we got today. It's not out just yet on anti-gravity. I've been sat here trying to check for updates every 10 minutes.
It's still not available for me. It'll probably be available in America first and then eventually it'll drift over to Europe. Um, intelligence versus output. It's like one of the fastest models. 300 tokens per second for extremely good intelligence. Apparently, they built an OS system, which is like the classic uh test. It's the one that they also did to show the power of I think it was Opus 4.7 at Anthropic, and it basically created an entire OS for $1,000, which is absolutely crazy. So, the other thing that they announced at the same time, which also is super super nice, is an update to anti-gravity.
I've said for a while, anti-gravity is extremely good. It's free to use, right? And when Gemini 3 Flash first came out, especially, it was one of the most intelligent models I've ever used. Like even it it wasn't as good as, you know, Opus 4.7 or whatever, but like it was the the gap wasn't that large and the speed difference and kind of the multimodal abilities of the flash models and also just Gemini generally were what drew me to it. And the fact that it was completely free to use inside anti-gravity. So, the other thing they announced or they just finished announcing, you can see right here, Google Anti-gravity available global today.
That might seem a bit weird if you're out of the loop, but they've just launched what they're calling anti-gravity 2.0. This is with Gemini 3. Flash inside or it will be very, very soon. The main reason I'm making this video is this right here. Right, for the next few weeks, my video wasn't on, guys. RIP. I just turned it on now. But for the next few weeks, this will be the best way to build and it will it's totally for free. Okay, so you can use this inside anti-gravity totally for free with the new Gemini 3.5 Flash.
Again, for free because they're trying to make up the gap, right? The way the gap works is um Opus 4.7 Anthropic is the very top, right? Everyone uses Anthropic. They are the best. Second is OpenAI. So what Open AI does is they give you more usage for $20 than Claude does. So what can anti-gravity do? What can Google do? they can give you free usage of one of their best models, Gemini 3.5 Flash. Now, they are probably going to be announcing another model very very soon as well. But like just in terms of um this video, we're talking mainly about Gemini 3.5 Flash.
There were some other announcements that I'll go through very very quickly as well. But this is what I'm excited about. I'm excited about anti-gravity 2.0. I'm excited to use Gemini 3.5 Flash. And I might even stream later if I do get access to this model. But just generally, if you're looking to build a project right now, you should go and build it inside anti-gravity, like if you've been if you don't even want to spend 20 bucks on codeex, right? If you've been waiting for a free opportunity, this is your free opportunity, provided Google doesn't change anything crazy.
I can't see them doing anything completely crazy like changing the uh pay for anti-gravity or whatever, right? But I'm hoping that they don't do that. So they've also added new hooks, new harness agent first. It was um they added sub agents as well and also async management which means you can go off and build something very very quickly. I will be testing that to its absolute conclusion as soon as I get access inside anti-gravity. Anti-gravity. Oh, it's here. Oh my god, I just got access. Holy Right, I might actually just go and test this real quick, guys.
Yeah, guys, it's too good not to test. I I need to test this. So, let's just go to uh a very specific repository here. Okay, guys. So, I have this Astro Builder Skill, which is a a really, really good test of a model. So, we'll just grab this real quick, and I'll just install this. So, let me just install this um into anti-gravity. So, let's go terminal, new terminal. So, you guys can follow along as well. I'll leave a link to the uh to the GitHub in the description. So, we'll do MKD Gemini 3.5 Flash.
I'm I've got very high hopes for this by the way guys. This is also a free account. I'm not paying for anything here. Um so ju just bear that in mind right as we do this. So I'm just going to install this. Um let me just see if that installs properly. Okay. So I need to do anti-gravity at the end here because I'm using anti-gravity. So there we go. So it's just that command and then just write anti-gravity like that. Beautiful. And then should be able to tag the skill. Yeah, there we go. So yeah, Astrobuilder skill build me an Astrobuilder website for a plumber in Actton ride called plumbing.
Hit enter here. So let's see. This is I'm so curious to see this. I have a feeling this is going to be stupid fast as well. Guys, literally go and build something with this right now. I'm telling you, it'll be really, really good. Okay, so just ask me a few clarifying questions. That's normally a good thing. um because it doesn't dive into things. So, it just basically said uh before I scap all the project database. Yes, I need a database. Did I say? Yeah. Okay. I said I needed a database. So, now it's just running.
It's creating everything now. Um images. So, it has an internal image generation tool. Anti-gravity. So, it's probably one of the best ways to make one of these websites to be honest. This is like a website that you can sell to someone basically or you know if you have a a service-based website then you can just use the skill. There's no fancy prompting here, guys. It's literally just I just tagged the skill and said, "Build me an as build a website for a plumber in Athenia called Plums Plumbing." Right? I didn't do anything else. So, just remember that when you see the final result.
It's not like I've it's not like I'm doing any crazy prompting or prompt wizardry or anything like that. I'm literally just saying do this and uh you'll see the result in a second. So, if you're someone who's not technical and you're watching this video and you don't have any experience, just remember that I haven't done anything special at all. Right? I've literally just uh I just ran a command. So I created the folder with mkdir. I went inside the folder with cd which is change directory right and then ran mpx github which is just a way to install the github repository that you can find in the description.
And then I just started by just sending this incredibly simple chat to uh nano banana uh sorry to gemini 3.5 flash inside anti-gravity. Guys, I just think for now I'm going to skip uh skip images for now. It takes too long. I don't really want to see the image generation. We all know that Nano Banana is good, right? I actually just want to see how good this coding model is. I've got very very high hopes for this. I'm really hoping it's not just more crap. Look how fast this is going. By the way, that's crazy fast.
So, yeah, the time right now 18:42. I mean, it it started maybe 2 3 minutes ago, right? But it's, you know, it's so fast. Wow. Just quickly, guys, huge shout out from our sponsor, me. This is harbor seo.ai. And if you didn't know, it's actually powered by Gemini. It's not something I talk about a lot because Gemini doesn't have like the best reputation uh right now. But once this has Gemini 3.5 Flash inside it, it's going to be even faster than it is now. It's already absurdly fast. But uh right now I use Gemini 3 Flash for LLM scraping and also for grounding search queries.
I'm going to change that over as soon as possible to Gemini 3.5 Flash, which will make this tool even better than it already is. For context, guys, we started in February 2027, um 2027, sorry, 2026. And uh we've got 600 pages published, 330,000 impressions, and almost 3,000 clicks already. That's almost 1,000 clicks a month and we've only got 150 to 200 customers who use this tool. Actually, there might be more than that, but uh so you can just see how effective this tool actually is. It gets the clicks for your website, right? SEO isn't dead.
It's just people just say that for for clicks on YouTube basically. Go and check out Harbor, guys. There's a link in the description and in the pin comment. You can get free trial and I read every single message. So, if you have any feedback at all, you can press this button here or this button here. Give me any feedback. tell me something's broken and it'll be fixed within a few hours of when I see the feedback, which is normally every single day. So yeah, go and check out Harbor Guys, link in the description, link in the pin comment.
It's an SEO content generator and it's the best on the market for the price. Okay, guys. So yeah, this is now using already it's it's already using its internal tool uh to to test the product. Uh very very fast, honestly. Absurdly fast. It's now trying to submit its own request. Oh, this is so interesting, guys. Honestly, watching this use this like a computer even though I just messed it up. Insane, guys. Absolutely crazy. I love this. Let's just see if it can finish up here. I just want to see if everything's working. Um that would be super impressive if it was just working already.
Okay, so I'm just going to cancel the test that it was doing there. Um that's fine. I just want to see what it's done basically. Okay, so for context, guys, that worked for 5 minutes, which is absolutely absurd that it um built that quickly. I'm just trying to see what the password is. There it is. Okay, so let's just log in here. Let's see if it managed to build the So, can't believe it's done all of it already. So, let's just click through here. The design is fine. It's not exactly It's more of a SAS obviously than, you know, a plumber, but it would probably get the job done, honestly.
And I did say, you know, do this kind of um design, right? So, we have, let's see, this is just one service page. This this isn't very good for SEO, I wouldn't say. Um, to be honest with you, let's just see if it does have No, it doesn't really have separate pages for each one, which is a bit of a disappointment, honestly. Uh, it's not what the prompt says at all, and this is bad for SEO. Um, it did manage to do everything in 5 minutes though and there's not a single error here. And um, it it's definitely impressive stuff.
Let's see if it made a site map. No. Okay, guys. Honestly, this for how quick it was, it's absolutely insane, right? It's got the little hovering thing that Opus 4.7 always does as well. I can't believe how quick this is, guys. Honestly, go and build with this today because it's free to use inside Antiggravity. I've got a completely free account. The limits will be very, very generous. G generous as of today. And also, not only that, the model was just released, so it'll be the best of the best. Not the best of the best, but for the price and for the speed, it is the best at the moment.
Right. So, in 2 weeks, I can't say, but as of today, this can probably build better than any of the Chinese models. I wouldn't be surprised if it was better than GBT 5.5 for some things as well. And it's just ridiculously fast and and free to use. So, go and check out Ingravity, guys. Go and check out the latest model. I'm going to leave the video there. I think that I will probably have another video uh very soon because there's going to be another model, I'm going to guess, uh being released. I wouldn't be surprised if they had already announced it while I was making this video.
Yeah. So, there it is. Gemini 3.5 Pro. I'm Oh, coming next month. Okay, that's good to know. I'm not really that bother about bothered about Gemini 3.5 Pro. I will probably continue using Opus uh 4.7 and also probably GPT 5.5. But yeah, uh they're announcing other things too. I'm not going to go through this in this video cuz I don't even know what it's about. But Gemini Spark, your personal agent dedicated virtual machines. Okay, so this is their open core basically. Interesting. Integrates with what does that say? Google products 3P tools by MCP. Okay, that's pretty cool because instead of having to have like a third party integration for OpenPaw, which you can't trust, who's reading your emails right now, you can do it with Gemini Spark.
So, this is a pretty cool update as well. Um, but I'll if I think it's worth making videos about it, I'll make videos. But for now, I'm going to leave this video there. Uh, thank you so much for watching. If you are watching all the way to the end of the video, you're absolute legend. Go and check out harbor seo.ai and I'll see you very, very soon with some more content. Peace out.
