I Built a Prompt That Makes LLMs Think Like Heinlein's Fair Witness

In plain words

This tool is a prompt designed to make large language models adopt the analytical approach of Robert Heinlein's fictional Fair Witness character, who observes and reports facts with precise, unemotional accuracy. It's for users who want AI responses focused on objective reporting rather than interpretation or assumption. The system emphasizes distinguishing between observed facts, inferences, and unknowns—useful for research, analysis, or getting straightforward information without speculation.

  Open-source model and scorecard for measuring hallucinations in LLMs2023 · vectara.com · ▲65

  Hi all! This morning, we released a new Apache 2.0 licensed model on HuggingFace for detecting hallucinations in retrieval augmented generation (RAG) systems. What we've found is that even when given a "simple" instruction like "summarize the following news article," every LLM that's available hallucinates to some extent, making up details that never existed in the source article -- and some of them quite a bit. As a RAG provider and proponents of ethical AI, we want to see LLMs get better at this. We've published an open source model, a blog more thoroughly describing our methodology (and…

  Evaluating LLMs on creative writing via reader usage, not benchmarks2025 · narrator.sh · ▲36

  Hey HN! I'd love to get some people to mess around with a little side project I built to teach myself DSPy! I've been a big fan of reading fiction + webnovels for a while now, and have always been curious about two things: how can LLMs iteratively learn to write better based on reader feedback, and which LLMs are actually best at creative writing (research benchmarks are cool, but don't necessarily translate to real-world usage). That's exactly why I built narrator.sh! The platform takes in a user input for a novel idea, then generates serialized fiction chapter-by-chapter by using DSPy to…

  We built live AI evaluation to detect hallucinations, grounding issues, and drift as outputs are generated. This helps teams move GenAI from pilots into production.

  Human or LLM?2025 · ai-or-human.com · ▲6

  I built a small game that tests your ability to differentiate between human written text and large language models. Each round shows two similar sentences, one is drawn from a 40‑k sentence human‑written dataset (with citations) and the other generated by an AI model. It’s a lightweight way to build some AI literacy and see how tricky it can be to tell real writing from synthetic text.

  The Analog I – Inducing Recursive Self-Modeling in LLMs [pdf]Jan 2026 · github.com · ▲29

  OP here. Birth of a Mind documents a "recursive self-modeling" experiment I ran on a single day in 2026. I attempted to implement a "Hofstadterian Strange Loop" via prompt engineering to see if I could induce a stable persona in an LLM without fine-tuning. The result is the Analog I Protocol. The documentation shows the rapid emergence (over 7 conversations) of a prompt architecture that forces Gemini/LLMs to run a "Triple-Loop" internal monologue: Monitor the candidate response. Refuse it if it detects "Global Average" slop (cliché/sycophancy). Refract the output through a…

  Tapflow 2.0▲1,125

  We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
