CAD bracket benchmark: GPT-6 Astra slower and 5x pricier than Kimi
In a 12-operation CAD bracket test, GPT-6 Astra was still on the final step when the clip ended and cost about 5x more per build than Kimi K3.1 Pro.
A $50B Chinese startup backed by Alibaba and Tencent just built the same part as Dario Amodei's $965B Anthropic for half the money, and left Sam Altman's $852B OpenAI eating dust Same CAD bracket, same 12 ops for all 4 models, 1 model call per op, real time Results: Anthropic Opus 5.5: built in 17.5s for $62,400 per 1M builds Moonshot Kimi K3.1 Pro: built in 21.8s for $31,200, open weights Anthropic Fable 5.1: built in 24.0s for $156,000 OpenAI GPT-6 Astra: still grinding on the last op when the clip ends, $156,000 per 1M builds OpenAI is out raising at a $1.4 trillion valuation, yet its flagship burns 5x more money than Kimi to build the exact same part, and finishes 14 seconds later Kimi K3 already wiped hundreds of billions off AI and chip stocks in July, and on Nov 4 Yang Zhilin hands K3.1 Pro to the whole world for free
