I think many cognitive scientists think language is a core part of human cognition, and that LLMs were a major advance in AI/cognitive science due to connecting AI algorithms with …

This was the core premise behind my research during grad school and beyond. My favorite project — which ultimately became my dissertation — was a proposal to connect reinforcement …

My team has been working on this in the concept of Turing Test and human vs. AI discrimination: https://arxiv.org/pdf/2605.06524 Specifically, our approach is to separate classic o…

Thanks all for the discussion! Would like to highlight two parts that maybe didn't come fully through, and we'll work on making this clearer: 1. CAPTCHAs can still detect AI agents…

I mean, their CAPTCHAs presumably have tons of data collected over the years, and they can't detect a pretty clear AI agent here: https://www.youtube.com/watch?v=UeTpCdUc4Ls

Yeah, we benchmarked against a few bot detection provides end of last year ( https://research.roundtable.ai/bot-benchmarking/ ), and Turnstile didn't do great when it came to AI ag…

This is relatively close to our conclusion from the paper: unless agents are specifically trained for the task and know all the information ahead of time, they're not able to gener…

My grad school research was on computational models of human/machine cognition, and I'm now commercializing it as a 'proof-of-human API' for bot detection, spam reduction, and iden…

In December 2024, Roundtable was a survey fraud detection company. Our product Alias analyzed typing patterns in open-ended text fields to catch bots and AI-generated responses. It…

Yup! It depends on your use case. Cloudflare is really good at network bot detection. Rate-limiting is super helpful here, for example during DDoS attacks. Our customers are a litt…

Check out a demo of a similar tool we created ( https://model-guessr.com/ ) that was bot-gated by Roundtable Proof of Human. Happy to talk more details about PoH (disclaimer: I'm a…

The 'Process Turing Test' extends the CAPTCHA from 'What would a reasonable person click' to 'How would a reasonable person click'. For example, hesitation/confusion patterns in CA…

Yeah, we've looked at it in the context of reCAPTCHA v3 and 'invisible behavioral analysis': https://www.youtube.com/watch?v=UeTpCdUc4Ls It doesn't catch OpenAI even though the mou…
