  • Behind every major scientific advancement lies countless human contributions. Some participants translate languages, others identify galaxies, or many simply share their daily experiences. In this short article series, we’re spotlighting 5️⃣ notable breakthroughs across science, technology, and society. This edition features Mozilla Firefox, UNICEF, reCAPTCHA, and more. 📰

  • As LLMs continue to evolve in sophistication and capability, the methods we use to evaluate their performance need to keep up. Among these methods, the "LLM-as-a-judge" concept has emerged. How effective is this technique overall? More importantly, how does human feedback factor into creating effective evaluation frameworks? In this feature, we explore the technical underpinnings, practical applications, and critical challenges of the LLM-as-a-judge methodology—with particular attention to how Prolific is bridging the gap between automated evaluation and essential human judgment. 🔗 https://lnkd.in/eYmhhxqz

    Enjoyed discussing the future of the human workforce behind AI with The Economist. While headlines often focus on automation, the shift that's happening is more nuanced: the type of human input needed for AI is evolving. Basic labelling is shifting towards nuanced evaluation, ethical testing, and specialised feedback – tasks requiring diverse skills, cultural understanding, and deep expertise. This creates new opportunities for people globally to shape the impact of technology on their lives. This is the "Human Intelligence Layer" in action. As I mentioned in the piece, Prolific is building the human data platform to support these challenges. We provide reliable access to the diverse, high-quality human perspectives essential for developing algorithms that are not just powerful, but also nuanced, fair, and aligned with real-world needs.

  • Which base model are you choosing? ⚒️ There are plenty of readily available LLMs that you can use as a base and fine-tune to your needs—but that’s the dilemma. Base models have different license types, sizes, guardrails, language capabilities, and more to consider. Besides the generalist range, there are also several domain-specific models that enterprises and app development teams can look at. We cover it all in our practical guide to building AI apps with LLMs. 📥 Download it here: https://lnkd.in/egVJQTHf #AI #LLMs #AIApplications
