Hi everyone 
We’ve added a new model to the AI Builder that many of you have been waiting for.
https://pickaxe.co/models/grok-4-20-reasoning
Grok 4.20 Reasoning is now available inside Pickaxe AI Builder.
This model is designed for stronger reasoning tasks, so if you’re building tools that require:
-
step-by-step thinking
-
complex problem solving
-
structured outputs
-
deeper analysis
…it’s worth giving this one a try.
How to use it:
-
Go to Builder
-
Open your Pickaxe
-
Select the model from the dropdown under your prompt
-
Test it live on the right panel
The model selection happens directly in the Builder interface, so you can quickly switch and compare outputs while building
If you experiment with it, would love to hear:
-
what you’re building
-
where it performs better (or worse)
-
any edge cases you notice
Your feedback genuinely helps us improve what gets prioritized next
