Brief

Lisbon AI highlighted @joanrod_ai as a speaker for its 23–24 September conference, promoting his StarVector project (open-source, open weights, thousands of GitHub stars) which evolved into QuiverAI. Their Arrow-1 model hit #1 on SVG Arena and was first to break 1500 Elo, displacing Gemini 3.1 Pro one day after launch. The thread frames vector-as-code models as editable alternatives to pixel-based generators.

Why it matters

StarVector, an open-source model by @joanrod_ai with open weights and thousands of GitHub stars, evolved into QuiverAI whose Arrow-1 model reached #1 on SVG Arena and became the first model to break 1500 Elo, displacing Gemini 3.1 Pro one day after launch.

Key details

  • Lisbon AI announced @joanrod_ai as a speaker for its 23–24 September event, promoting a 'vector-as-code' approach that treats vector graphics as code (enabling editable layers, recoloring, and animation) as a contrast to pixel-based generative models.

Amazing speaker choice. Can't wait!

AI got shockingly good at making pixels: images, video, anything you can describe.
But a pixel seems to be a dead end. You can't edit a layer, recolour a system, or animate a single shape. Real design is structured. It's code. And almost no model writes it well.

@joanrod_ai is one of the few who can. He built StarVector, an open-source model that treats vector graphics as code, not pixels. Open weights, thousands of GitHub stars.

It became @QuiverAI , and their model Arrow-1 took #1 on SVG Arena is the first to ever break 1500 Elo on a design leaderboard, knocking Gemini 3.1 Pro off the top one day after launch.

Come to Lisbon on 23–24 September and watch a model draw the way a designer actually works.
