Hey HN, Joe and Ethan from Tonic.ai here again. Alongside last week’s announcement of Tonic Validate Metrics (<a href="https://news.ycombinator.com/item?id=38012126">https://news.ycombinator.com/item?id=38012126</a>), we’ve also released an open-source SDK for logging the performance of Retrieval Augmented Generation (RAG) applications during development, Tonic Validate Logging. Tonic Validate Logging is used to log your RAG responses to the Tonic Validate App. When RAG responses are logged, metrics are calculated on the responses using Tonic Validate Metrics.<p>We were working on a RAG-powered app to enable companies to talk to their free-text data safely when we ran into trouble tracking the performance of our models’ responses. So we built these solutions to help us out: Tonic Validate Metrics for benchmarking, and Tonic Validate Logging + the Tonic Validate UI to track performance improvements to help us choose the best system possible. Tonic Validate provides a simple and convenient UI that you can get for free at <a href="https://validate.tonic.ai/" rel="nofollow noreferrer">https://validate.tonic.ai/</a>.<p>Two key benefits of using the Tonic Validate tools are (1) automatic logging and metrics calculation with just a few lines of code and (2) a simple, convenient UI to help visualize your experiments, iterations, and benchmarking results for your RAG applications.<p>Our hope is that these packages will become a useful part of the technique layer behind the growing suite of LLM-powered applications and, more importantly, that the open-source packages evolve and thrive with your contributions.<p>We’re excited to hear what you all think in the comments!<p>Read our docs here: <a href="https://docs.tonic.ai/validate/" rel="nofollow noreferrer">https://docs.tonic.ai/validate/</a><p>Get the open-source Tonic Validate Metrics package at: <a href="https://github.com/TonicAI/tvalmetrics">https://github.com/TonicAI/tvalmetrics</a><p>Get the open-source Tonic Validate Logging SDK at: <a href="https://github.com/TonicAI/tvallogging">https://github.com/TonicAI/tvallogging</a><p>Sign up for the Tonic Validate UI here: <a href="https://validate.tonic.ai/" rel="nofollow noreferrer">https://validate.tonic.ai/</a>
