Where we disagree
Rank and Agent Arena Rank more than 2 positions apart.
DeepSeek#7 · Agent Arena #4 · Meaningful disagreement
Agent Arena rates DeepSeek competitively on multi-step coding work. Rank is more cautious for non-technical founders because the consumer surface is bare and the obvious path in is API-first.
Moderate agreement (±2): Llama, Mistral.
Most bullish relative to Agent Arena
Models the FutureFounder Score ranks higher than Agent Arena does.
ChatGPT
#1 · Agent Arena #2 · +1
FutureFounder Score weights ecosystem and usability more than Agent Arena's task-execution method.
Most cautious relative to Agent Arena
Models the FutureFounder Score ranks lower than Agent Arena does — usually models that execute tasks well in isolation but cost a non-technical founder more time, money, or workflow friction than the leaders.
DeepSeek
#7 · Agent Arena #4 · -3
Agent Arena rates DeepSeek competitively on multi-step coding work. Rank is more cautious for non-technical founders because the consumer surface is bare and the obvious path in is API-first.
Llama
#8 · Agent Arena #6 · -2
Agent Arena scores Meta's hosted reference model on task completion. Rank values what Llama enables — the open-weight foundation everyone else's agents are built on — not its performance as a finished agent.
Mistral
#9 · Agent Arena #7 · -2
Agent Arena puts Mistral below the US frontier on raw task execution. Rank holds it at the same position for the specific case Mistral wins outright: EU data residency plus open-weight commercial backing.
Why the two systems differ
Agent Arena scores reward finishing real multi-step work — building, debugging, running tool chains, completing agent workflows. The FutureFounder Score rewards leverage for a non-technical builder: speed-to-value, price-for-value, ecosystem fit, and how easily someone running a business can extract real output. A frontier model can dominate Agent Arena and still be the second-best founder pick because the workflow around it is heavier.
