Opus 5.5 vs GPT-6.1 Sol in Blender: One Cost 7x More

The test

The prompt

Build a game-ready 3D character for a Godot game: a stocky dwarf miner with a thick braided beard, a leather helmet with a lamp on the front, a wool shirt under a leather apron, a wide belt, heavy boots, and a pickaxe in his right hand. Make him look like the reference picture. Build him in Blender. Blender 5.1 is installed on this PC and blender is on your PATH: run it in the background from your shell, with blender --background --python and scripts you write, and keep those scripts and your .blend in a folder named blender in this game, so he can be built again from them. Everything about him is made in Blender by your scripts: the mesh, the materials, the skeleton, the skinning, and two animation clips you key yourself, named Idle and Walk. Both loop, and the Walk is a walk cycle that stays in place. Export him as one .glb into this game. Anything that ships with Blender is yours to use. Don't use Flockbay's modeler or its asset library, don't use Tripo, Meshy or any other 3D tool or service, and don't download anything: no model, rig, animation, texture or add-on. He has to look right from every side, not just the front, and hold together while he walks: his knees, elbows and shoulders bend cleanly, his beard and apron move with him, nothing pokes through, and the pickaxe stays straight and in his hand. Keep him within a triangle budget a game could ship. In the game he is about a dwarf's height in metres, stands on the floor and faces -Z, Godot's forward. Then put him in the game: one small scene with a floor, a light and a camera at his side, where he walks back and forth across the floor on his own, playing the Walk clip and turning round at each end, with his feet planted, not sliding. Make it the game's main scene. Use Blender from your shell to build him and to look at him. Run and test the game only through Flockbay's tools: flockbay_play, flockbay_run_headless, flockbay_script_errors, flockbay_game_input, flockbay_game_get, flockbay_game_set, flockbay_game_screenshot, flockbay_last_run and flockbay_stop. Don't start Godot from your own shell, and if one of those tools can't do something you need, say exactly what was missing in your handover. Look at your own work, fix what you see, and hand him over when you think he's done.
