Automatic prompt optimizer for LLMs

In plain words

Automatic Prompt Optimizer for LLMs is a tool that refines prompts for large language models to improve their output quality. Users input their prompts and the system automatically enhances them for better results. The tool is designed for anyone working with LLMs who wants to get more effective responses without manually rewriting their instructions. It streamlines the process of prompt engineering, which typically requires trial and error.

  Prompt Engine – Auto pick LLMs based on your prompts2024 · jigsawstack.com · ▲93

  Nowadays, a common AI tech stack has hundreds of different prompts running across different LLMs. Three key problems: - Choices, picking from 100s of LLMs the best LLM for that 1 prompt is gonna be challenging, you're probably not picking the most optimized LLM for a prompt you wrote. - Scaling/Upgrading, similar to choices but you want to keep consistency of your output even when models depreciate or configurations change. - Prompt management is scary, if something works, you'll never want to touch it but you should be able to without fear of everything breaking. So we launched Prompt…

  Relari – Auto Prompt Optimizer as Lightweight Alternative to Finetuning2024 · ▲32

  Hi HN, we are the founders of Relari (https://www.relari.ai). We launched our LLM evaluation stack on HN a few months ago (https://news.ycombinator.com/item?id=39641105), which is now used in production by AI teams at companies like Vanta and PwC. We have since expanded to directly optimizing parts of an LLM pipeline using a data-driven approach. In particular, we see a lot of potential in the Auto Prompt Optimization—which could be an attractive alternative to fine-tuning in many cases—to use data to align LLMs for domain-specific tasks. Here’s a demo video:…

  RL Agent that can auto-optimize your LLM prompts2024 · nomadic-ml.github.io · ▲14

  Hey everyone! Along with my team, I've developed a reinforcement learning system that automatically optimizes LLM prompts, complete with a visualization feature to track both prompt structure and learning progress over time. Take a look here: https://nomadic-ml.github.io/nomadic/cookbooks/Nomadic_Promp... Check out our website too:https://www.nomadicml.com/ In terms of how this visualization works: The RL Prompt Optimizer employs a reinforcement learning framework to iteratively improve prompts used for language model evaluations. At each episode, the…
