    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…

    Hi HN! We’re a team of ML validation specialists and we’ve been building /Spec27, a tool for testing whether AI agents still do their job safely and reliably as models, prompts, tools, and surrounding systems change. We started working on this because a lot of current LLM evaluation work seems aimed at scoring general model behavior, while many teams are deploying systems that have a specific mission to fulfill. Many of the tools also assume you have full access to the agent stack and traces so you can place SDKs and Gateways, but a lot of agents are being created on vendor platforms…

    Hey HN, we're launching SprintZen – an AI-powered test case management platform that helps teams write, organize, and sync tests without the mess. It generates test cases from user stories or PRs, integrates with Jira, Linear, and Monday, and auto-reports bugs. We built this after working with 15+ startups (YC-backed and others) and seeing how painful test maintenance can get. Would love your feedback. To try this out you can create your account here - https://on.sprintzen.app/login

    Hi HN, Hugh and Vince here. LLMonitor helps you record, trace & search your LLM queries and chatbot conversations. You can also capture user feedback on your frontend and correlate it with backend LLM queries then use that to fine-tune your own models. The project started has an internal tool in our previous (failed) AI startup. We’re aware the LLM observability space is very crowded. Apart from being open-source, we differentiate with: - Model-agnostic and minimal lock-in (no MITM of requests). - High focus on DX and dashboard clarity. - Support for complex scenarios: e.g. a chatbot that…

    # Show Community: MIP - A Molecular Intelligence Platform for Biology Teams Hi, Community! I'm Sid, founder of Purna AI. We've been building a Molecular Intelligence Platform for the last few months, and now it's in research preview. It's a single workspace where molecular medicine teams can go from raw biology data to interpretation without juggling a dozen disconnected tools. ## The Problem If you work in clinical genomics, rare disease research, computational biology, or similar fields, your workflow probably looks like this: export variants from one tool, look up annotations in another,…
