In this cookbook we will show how to calculate a hallucination risk based on the research paper LLMs are Bayesian, in Expectation, not in Realization and this GitHub repo, https://github.com/leochlon/hallbayes. In this notebook, we’ll use the OpenAIChatGenerator from haystack-experimental.
Notebook by Kacper Łukawski 🚀 Part of Haystack 3.0 Launch Week: five days of new drops (July 20–24). In this notebook, we build a fully local, fully async agent that uses a skill to change how it reports back, and a custom bash tool to actually use the machine it runs on.
Notebook by Bilge Yücel 🚀 Part of Haystack 3.0 Launch Week: five days of new drops (July 20–24). Every call to Agent.run() returns metadata alongside the agent’s reply. In this cookbook you’ll use that metadata, and Agent hooks, to enforce soft and hard budget policies.
Today, we’re happy to announce the release of a new major version: Haystack 3.0 🎉 Haystack is an open-source AI orchestration framework for building production-grade agents with full control and flexibility, and 3.0 is the release where agents move to the center of the framework.
