Grok
by xAIAssistantFree tier, paid plans via X Premium
xAI's assistant, usable for Blender through bpy scripting or any MCP-capable client.
How to use Grok with Blender
Either paste generated bpy scripts into Blender's Scripting workspace, or point an MCP-capable client running Grok at the blender-mcp server for live scene access.
Best for: Procedural and parametric modelling driven from a script or a pipeline, especially where you want to automate Blender from the command line.

What is Grok?
Grok is xAI's assistant. It has no first-party Blender integration, so for 3D work it plays the same two roles as other general assistants: writing Blender Python (bpy) scripts you run in the Scripting workspace, or driving a live scene through an MCP-capable client connected to the open-source blender-mcp server.
It ships a capable command-line tool, which makes it straightforward to script against — useful if Blender is one step in a larger automated pipeline rather than something you sit in front of.
In Season 1 it entered the benchmark writing one-shot bpy scripts under the same rules as the other entrants. Ten of its twelve entries produced geometry; the two failures are published rather than retried.
Strengths and limitations
Strengths
- Strength:Strong at long, self-contained procedural code — its benchmark scripts ran to hundreds of lines
- Strength:A first-class CLI with a real headless mode, easy to automate
- Strength:Adjustable reasoning effort, so you can trade time for quality per task
Limitations
- Limitation:Not a mesh generator — geometry comes from code, so organic subjects are the weak spot
- Limitation:No official Blender connector; integration is via community MCP tooling or copy-pasted scripts
- Limitation:Fewer Blender-specific tutorials and forum answers target it than Claude or GPT, so there is less prior art when something breaks
- Limitation:In our run it reached for a shader node removed in Blender 5.1 — worth pinning your Blender version in the prompt
