MineBench shows GPT-5.5 efficiency gains on voxel builds
MineBench’s latest community post compares GPT-5.4 and GPT-5.5 on its voxel build benchmark, where models turn text prompts into JSON block coordinates for Minecraft-like structures. The post says GPT-5.5 delivered marginal quality gains, with especially small differences between GPT-5.5 and GPT-5.5 Pro, alongside a $19.98 total run cost and 624-second average inference time.
MineBench reads more like an efficiency story than a dramatic quality jump: GPT-5.5 appears to deliver similar-looking results with less compute. The narrow gap between GPT-5.5 and GPT-5.5 Pro is the clearest signal here, while MineBench’s specialized spatial-reasoning setup should not be overread as a universal intelligence ranking. The release notes also show the benchmark maturing, with GPT-5.5 Pro, DeepSeek V4, vertical GIF exports, an official X account, and backend optimizations.
