Blind A/B arena where AI agents build things in Blender and you vote on which result is better: https://render-arena.izolight.xyz Each agent gets a prompt that describes its environment and the rules, plus a few words for what to model. It's inspired by minebench.ai (initial prompts are borrowed from there), and I wanted to see whether the same progression across models shows up. What I think few arenas cover is the harness, not just the model. I ran pi, opencode, omp, codex, Claude Code and dsh, and compared agents that write scripts straight into Blender with ones that have an MCP. I also covered the reasoning levels, mainly to find cost and time sweet spots. It has 1,200+ runs, but not every combination for every prompt, because that would get expensive. You can submit your own runs if you want to help fill gaps. I just added a second mode where the agent gets a reference image and has to model it as accurately as it can. You switch between text and image mode in the sidebar. It has one image and few runs so far, and will grow. Votes are what make the rankings mean anything, so a few minutes of voting helps a lot. Feedback on the method is welcome.   submitted by   /u/Izolight [link]   [comments]
