Fable 5.2 seems to perform extremely well for 3d scene generation. Downside is time. It's substantially slower than Opus 5.5, which means longer sessions, potentially resulting in higher total expenses.

[Spline @splinetool]

Fable 5.2 is ranking #1 on Spline Arena for 3D Scenes.

Exciting

We believe voice is the most natural way to interact with intelligence, so we created Dessa, the most authentic full-duplex speech model ever built. Talking with it feels like talking with a person…full of emotion, nuance, pauses, and a natural cadence.

This is pretty smooth; now you can use Spline directly from chatgpt/codex

[Spline @splinetool]

Introducing Spline for ChatGPT.

Create and edit any 3D interactive scene directly within your ChatGPT or Codex chats.

Available now from OpenAI plugin's ecosystem.

[Alejandro Leon @alelepd]

this is next level of coolness

[Tesla @Tesla]

Real life, baby

[Alejandro Leon @alelepd]

Nice!

[Google @Google]

Today, Gemini 4 Argon is officially rolling out.

I made the new iPhone Duo animation in @splinetool V2.
I asked Astra to create the blur effect and gave it some images from the Apple website.
It wired up the webcam for me and recreated the main UX.
The directional blur is done in code, with spline.createCustomMaterial and some WebGPU TSL ;)

[Alejandro Leon @alelepd]

smooth!

[Dmitry Lepisov @DmitryLepisov]

Wait… what if Apple animated its logo in the iPhone Duo style?

[Alejandro Leon @alelepd]

fluids on spline

[Spline @splinetool]

Water simulation in Spline v2 made with agents (Astra)

[Alejandro Leon @alelepd]

Would be nice to see the progression from this into a more complex structure.

[Marco Fugaro @marco_fugaro]

I asked Astra to build me a protein visualization app using @splinetool V2, it came up with this website!

It pulls the data directly from the Protein Data Bank website, so it's accurate, and it lets me switch between the 2 types of protein visualization

[Alejandro Leon @alelepd]

Lots of details here

[Marco Fugaro @marco_fugaro]

I made this website to showcase the features of an offroad vehicle, and snow was the perfect setting! ☃️
made this in @splinetool v2 and the Dust layer used as snow on the models was perfect for this use case!

[Alejandro Leon @alelepd]

Love the lighting on this.

[Spline @splinetool]

Making a robot with gpt 6 astra in Spline.

The robot uses a solver that detects collisions while walking and self corrects its pose; similar to how it would work in real-life.

[Alejandro Leon @alelepd]

This is fascinating/satisfying to see.

[Spline @splinetool]

You can built this now with Spline agent (astra) or with Spline MCP.
Everything is editable.

[Alejandro Leon @alelepd]

This looks good. I wonder if same technique can be spplied for adding microscopic texture details on a surface.

[Gábor Pribék @gaborpribek]

friday experiment: street-level map detail in an interactive 3D @splinetool scene.

[Alejandro Leon @alelepd]

Nice textures here. All made with Spline V2

[Alejandro Leon @alelepd]

This is about to become next level

[Joseph Azar @parazar]

You can recreate this Flight Simulator game super easily with @splinetool v2.
I started by giving it an image of a plane, then this prompt:
'create a Full Plane Game that we can control, use Custom Code and TSL. create infinite World, use the real sky of spline with the clouds, add rings the plane can fly through, create a shader effect and an animation when we fly through them'

[Alejandro Leon @alelepd]

Making 3d product presentations is now unlocked

[Spline @splinetool]

Spline V2 agents at work. Build a drill, add animation to change battery triggered by mouse events.

[Alejandro Leon @alelepd]

Pretty cool 3d icons

[Dmitry Lepisov @DmitryLepisov]

Branding shouldn’t disappear when you open the product.

For @responsiveio we created a custom icon system that carries the brand into the UI.
Distinctive, but still clear and functional.

Here’s how it actually lives inside the product 👇

[Alejandro Leon @alelepd]

Nice work here with these input-driven animations

[Gonçalo Teixeira @goncalotex]

I'm impressed by the scenes and animations that the @splinetool AI agent is producing 😮

Started with a detailed prompt for a drone, then refined some details and materials manually, and finally, asked the agent to animate and make it interactive by following the mouse.

It made the animation with custom code, a new feature from Spline v2.

Find the initial prompt below 👇

[Alejandro Leon @alelepd]

Is super impressive that this works so well.

[Joseph Azar @parazar]

You can easily build a virtual pottery demo in @splinetool v2. I was blown away by how fast the built-in AI agent is, and by how well it understands physics. You can even shape it from the inside, pushing the clay out to hollow the vase.

That vessel section in the top right? The agent suggested it!! So handy.

You can use your mouse, or your hands with webcam tracking.
I built a tool that follows the shape of the vase, you can also trim off the extra clay.
Every element in the scene was created by the agent. I started this demo this morning!!

Working with Spline is so fast.

Dropping some prompts below to help you build your own.
