Gemini 3, Anti‑Gravity IDE, Nano Banana
Key Points
- Gemini 3’s launch was broadly hailed as a strong model—unlike the contentious rollout of GPT‑5—and Google paired it with “anti‑gravity,” a fork of VS Code that grants AI agents full execution privileges in the developer environment.
- Anti‑gravity lets agents read, edit, run code, install dependencies and record their actions, positioning Google to own the entire development lifecycle and shifting the competitive focus from benchmark scores to who controls the default AI‑enabled IDE.
- The strategy faces challenges because developers are loyal to their editors, care deeply about ergonomics, and competitors such as Cursor are also building agentic IDEs, making the long‑term outcome uncertain.
- The other headline is Nano Banana Pro, a visual‑reasoning model that can accurately render UI elements—including headings, labels, multilingual text, and 4K graphics—combine up to 14 images, and turn image generation into a routine part of product‑engineering workflows.

This was one of the biggest weeks in AI
that I can remember. Here's the top six
stories that mattered. Number one, the
release of Gemini 3. And I'm going to
throw anti-gravity in there as a bonus.
Gemini 3 is Google's new model. It
topped most of the benchmarks, but
that's not what matters. What matters is
that people around the world picked up
that model, started to use it, and
agreed. Unlike the launch of Chad GPT5
where there was widespread disagreement
and controversy around the launch itself
regardless of the benchmarks, everyone
pretty much agreed that Gemini 3 is a
very strong model. That's certainly been
my experience. I wrote up a whole post
on it. Anti-gravity goes with Gemini 3.
It is a fork of VS Code for developers
where AI agents have full execution
privileges. They can read and edit
files. They can run on your terminal.
They can install dependencies. You
control the level of autonomy they have.
They can record artifacts, plans, diffs,
decisions as they go, so you can monitor
and control what they're doing.
Basically, anti-gravity turns VS Code
into a place where agents do work. Now,
this matters because Google is trying to
own the developer environment, not just
the model. So, if anti-gravity becomes
the place where more developers write
code, Google doesn't just win model
usage here, they win the entire
developer life cycle. And so the
competitive game shifts from whose model
has the highest eval score to whose
environment is the default place where
work gets done and where agents do real
work. Google is betting that the Agentic
IDE is going to become the AI operating
systems shell. And so we will see how
this plays out. There are obviously
other players in the mix. Cursor is a
big one. But Google has put their stake
in the ground and said they're not just
a modelmaker at this point. They want to
own the development environment as well.
So anti-gravity could become the central
surface where agentic workflows run and
the place where ultimately you shape the
code that drives the compute experience.
That is not a guarantee. Developers tend
to be loyal to their editor. They tend
to care about the ergonomics of what
they're doing and they don't like to
switch. And so Google is making a
long-term play here and we'll have to
see how it plays out. Story number two,
Nano Banana Pro. It is not just an image
model. It is a visual reasoning model
that has solved correct text rendering
and conceptual relationships. This is
not about cutesy captions. It's not
about special illustrations. It is about
UI level image generation that can
correctly do headings, labels, menu
structures, multilingual content,
paragraphs. It can summarize an entire
earning statement into a single slide.
It also supports 4K output. It can
combine up to 14 images at once.
Fundamentally, Nano Banana Pro turns an
image into an interface. This is the
first moment when image generation is
now part of your regular product
engineering workflow. And not just
marketing, not just art. It's the image
becomes a way to iterate on visual
surfaces in seconds. It enables agents
to plug in and iterate on visual
surfaces that they couldn't run,
iterate, see, build on before. So agents
can build landing pages, critique them,
pull them back, try new email designs,
try new onboarding flows. It's as if
Figma automation and slide deck
automation and UI design automation and
Tableau all got rolled into one. This is
so new that we're still figuring out the
impact, but a few places this could go.
Closed loop design becomes real, so
agents can generate, read text, revise,
and test right in the browser. You can
have entire product surfaces become
codifiable. the UI just becomes another
completion target. So you can generate
as you go. This has always been the hype
is that AI can generate as it goes. But
having a visual tool like this helps to
make that more plausible even if that's
not the most common user interface. This
is absolutely going to pressure OpenAI
and Anthropic to advance their
multimodal pipelines. Now one thing to
watch, enterprise trust is still low for
generative images. The fact that it's
good doesn't mean that enterprises will
immediately trust it. even if it is good
enough for most enterprise use cases.
Text accuracy is excellent, but layout
consistency across multiple generated
screens is still a hurdle. And there is
a limit to the amount of text you can
reasonably fit in an image, which I
would argue is driven mostly by RARI's
ability to process, less so by the
model. But if you're trying to do very
heavy text and image, this is still not
the right model for that. That being
said, for all practical purposes, the
way to think about Nano Banana Pro is
that visual reasoning has been solved
and we have other problems to work on.
We have to work it out how it gets into
our workflows, etc. But the ability of
the model to generate what we ask for
and develop useful work artifacts taken
care of. Story number three is SAM or
the segment anything model version
three. It's a computer vision model from
Meta that segments and identifies
concepts, not just shape. That is
absolutely massive. It is a chat GPT
moment for video, for three-dimensional
planning, for workflows and automation
and manufacturing, etc. Let me explain
why. You can ask SAM 3, find every
forklift in these videos. Find people
not wearing safety vests in these
videos. Segment every red object in this
video. track the brown dog across the
scene. No manual clicks, no bounding
boxes, just plain language. So, SAM 3
shifts vision from like pixel geometry
and finding where the shape is to
semantic perception. In other words, the
model can see like we do and the model
becomes queriable. So, like just as you
can ask a human, where is the blue trash
can in this video? You can now ask the
model that it turns every image, every
video, every camera feed into a
searchable data set. Vision becomes a
natural language interface. There's a
lot of implications for this. I think
we're just barely scratching the
surface. Annotation for AI training is
going to drop from weeks to minutes.
Robotics perception pipelines are going
to get way simpler. Video editing is
going to transform. Masking took days
before and now it takes seconds. Content
moderation at scale is very easy. Photo
and video apps may adopt SAM 3 as a
magic wand concept editor. Now, it's not
perfect. Zero shot semantics are good.
Concept edges can blur a little bit.
It's going to get better. But just as we
regard Nano Banana Pro 3 as solving
visual reasoning, we should regard SAM 3
as fundamentally solving semantic
perception. It is good enough. It works.
Huge pressure on Google to improve their
model and on Open AI by the way after
this. Meta did a great job shipping
this. Number four is marble world layer.
I think this got slept on and I'm
excited. It is a generative 3D tool that
builds stable, editable, and exportable
environments with Gaussian splats,
polygonal meshes, realistic textures,
spatially consistent rooms and
buildings, and it has a chisel editor
that lets you define structure and an AI
that fills in details. It's from World
Labs, led by famous AI researcher Fe
Lee, and it matters because it makes 3D
content creation workflow grade for the
first time. So, this is not like a
production pipe. This is a true
production pipeline. It's not a research
demo. And I've used it. It's incredible.
3D worlds are not just generative toys.
You can actually do game development in
this tool, film VFX in this tool,
simulation and robotics in this tool.
Essentially, spatial AI is jumping into
the mainstream. This could dramatically
lower the cost of previs for films. It
could enable world building uh for AR
and VR apps. It's almost trivial. It's
an early concept or an early version of
a 3D Figma, but it's actually a
production application. Now, is the
Fidelity absolutely perfect? No. Is it
good enough that we can start to see
where the future is going as far as 3D
spatial rendering in AI? Yes. And that's
a huge deal. Number five, G story number
five, GPT5 scientific reasoning paper.
This is a peer-reviewed preprint showing
that GPT5 is doing real scientific
works. It proves new theorems. It
discovered symmetry generators in cur
black hole physics. It proposed
biological experiments that matched
unpublished lab results. So, it couldn't
have seen it beforehand. It surfaced
cross-domain literature insights. The
key contention of the paper is that when
you look across all of these at once,
it's not helping. It's actually
contributing original results. This is
from OpenAI, but it's not just an OpenAI
internal paper. And so, there's less
concern around bias there. It has
academic collaborators out of Oxford,
Cambridge, Harvard, Vanderbilt, and
Jackson Lab. And so why does it matter?
This is the cleanest proof yet that
frontier models are starting to behave
like research collaborators, not just
assistants. It also sort of punctures
the idea that the all models are
commodities now argument. For frontier
reasoning, for deep math, for physics,
for biology, model quality is not
interchangeable. And every researcher
that I have spoken to or who has spoken
publicly insists that for that kind of
research, GPT5 or 5.1 Pro is the gold
standard. Now, there are some
specialized models from Google that are
good for particular applications, but if
you're doing scientific reasoning as a
practice, the gold standard appears to
be 5.1 Pro from Chat GPT. And this
continues to go with the theme that
these models are specializing and the
way we use them is specializing. Now,
GPT5 Pro is not perfect, but again, just
as we look at the 3D world generator
with Marble, this is enough to show a
fundamental change in role. And so,
instead of thinking of chat bots as
minions that go do jobs, these
scientists are increasingly regarding
GPT5 Pro as a thinking partner that
helps them to make novel discoveries and
that is able to propose and prove novel
theorems that they can then validate.
And that's a big step for an LLM. Story
number six, OpenAI and Fox Con have
created a partnership that will build a
US manufactured data center optimized
for AI. That includes racks, cooling
systems, power delivery enclosures. It's
a it's a move that signals that Frontier
Labs are entering the era of physical
vertical integration. And so owning the
metal is going to let OpenAI deploy
models faster, reduce compute
bottlenecks, control costs, potentially
avoid geopolitical risk, build custom
racks optimized for their training
stack. What's interesting is that this
gives OpenAI a lot of flexibility. They
can build custom racks tailored for
training, for inference, for memory
architecture. They can build very power
efficient layouts. They can optimize
data centers. This is the beginning of a
hyperscaler era for physical AI
factories, and I expect to see more of
this. Last but not least, I wanted to
show you a really cool way to visualize
this week's news. So, this is a slide
deck that I created using Notebook LM
and I was able to get the entire news
story into the slide deck. I'll share
this along uh with the prompt that I
used as part of my newsletter this week.
And the other thing I want to call out
is I actually used a specialized prompt
tool to build this so that I got the
full story. I basically put the full
story of the narrative in and I got the
prompt tool to give me a very structured
prompt to make a deck like this. And
I'll be talking a little bit more about
that in my story on Monday. But I think
this is really cool. And so I'll be
sharing this deck and uh sharing the
prompt that I got to build it as well.
Happy Saturday. Catch your breath. And I
cannot wait for what next week holds.
The AI race just continues to
accelerate.
