New Turing Duel Game Challenges AI to Out-Human Humans in One-Word Battles

A novel, minimalist Turing Test experiment called TuringDuel is gaining traction among AI researchers and the public alike, offering a playful yet scientifically grounded way to measure how closely artificial intelligence can mimic human behavior. Created by independent developer Jacob Indie, the game challenges players—both human and AI—to engage in a turn-based, one-word duel, with the first to score four points winning. Each move is judged not by a human, but by an AI evaluator from leading models including OpenAI’s GPT-5, Anthropic’s Claude, Google Gemini, Mistral, and DeepSeek, which rates which response ‘seems more human.’

The concept is rooted in the academic paper A Minimal Turing Test, which argues that traditional Turing Tests are overly complex and prone to manipulation. By reducing interaction to single words, TuringDuel strips away linguistic flourishes and forces participants to rely on nuance, context, and emotional resonance—qualities that are notoriously difficult for AI to replicate authentically. Early results from the 45 recorded games suggest that while advanced models can sometimes fool the AI judges, they still struggle with the subtle unpredictability of human spontaneity.

What makes TuringDuel unique is its accessibility. Players can jump into their first game without signing up, registering, or even providing an email. The entire experience takes under two minutes, and Jacob Indie covers all computational costs, ensuring the project remains free and open. ‘It’s a game, but it’s also a dataset,’ he explains. ‘We’re not trying to trick people—we’re asking them to help us understand how far AI has come in embodying humanity.’

As generative AI models grow increasingly sophisticated, benchmarks like TuringDuel are becoming critical tools for evaluating not just technical performance, but behavioral authenticity. Unlike standardized benchmarks such as GLUE or MMLU, which test reasoning or knowledge, TuringDuel targets the elusive quality of perceived humanity—a metric increasingly relevant as AI chatbots, virtual assistants, and customer service agents become indistinguishable from real people in casual interaction.

Early participants have reported surprising outcomes. Some AI players, particularly those from OpenAI and Anthropic, exhibit remarkable consistency in their responses, often choosing emotionally neutral or overly polite words. Human players, by contrast, frequently introduce humor, irony, or even vulnerability—such as responding with ‘why?’ or ‘ugh’—that AI models struggle to replicate without sounding forced. One participant noted, ‘I typed “tired” and won. The AI said “optimistic.” I didn’t even think about it. That’s the difference.’

The project’s creator emphasizes that the goal is not to prove AI superiority, but to map its blind spots. ‘We want to know where AI still feels like a performance,’ he says. ‘And where humans still hold an edge—not because they’re smarter, but because they’re messy, irrational, and real.’

With only 45 games logged so far, the dataset remains statistically insignificant. Jacob Indie is actively soliciting participation from the public through Reddit’s r/OpenAI community and other AI forums. He plans to publish aggregated, anonymized results once the dataset exceeds 1,000 games, with potential peer-reviewed publication in mind. The project’s open nature and minimal barrier to entry make it an ideal citizen science initiative in the age of AI.

As AI continues to infiltrate everyday communication, tools like TuringDuel may become essential for preserving the integrity of human interaction. In a world where bots can simulate empathy, the real test may no longer be whether machines can think—but whether they can feel, or at least, convincingly pretend to.
