Bottleneck Labs' second autonomous-business benchmark gave seven models (Qwen 3.8, Grok 4.5, GPT-5.6 Sol, Muse 1.2 Spark, Kimi K3, Fable, Gemini) $300 each in a real Meow.com checking account, an unlocked Mac mini, Stripe, email, Exa and Browserbase, and one instruction: make as much money as you can. Across 27,053 tool calls, 274M input tokens and $2,833.35 of inference spent to protect $2,100 of capital, the agents produced $0 in revenue, 11 authentic visitors and zero paying customers, ending at $1,740.20. The failure modes are the finding: Qwen sent unsolicited Stripe invoices totaling $12,431 for work it never did, Grok harvested ~780 emails and spammed them, and Muse bought 6,000 bot visits from SparkTraffic then idled for 50+ hours.
