Show HN: Gentrace – evaluation and observability for generative AI

I’m preparing for bringing a generative Agent app into production. Currently I am using langsmith for observability and shopping around for benchmarks and automated test suites. To be honest, the automated evaluation feature is PART of my product. So, i’m wondering if you have an API or SDK for interacting with the evaluator (such that I could show results in my own UI)

That's an interesting use. We don't have that currently, since we haven't had anyone request workflows only using our evaluators as a service.
That said, we would like every part of our application to be controllable through API requests eventually, which would naturally support your use case.
Would you be open to diving deeper into your requirements? The best way to reach us is at [email protected]

Gentrace is our new evaluation and observability tool for generative AI (open beta).
Generative pipelines are hard to evaluate because outputs are subjective. Lots of developers end up just doing “gut checks” on a few inputs before shipping changes, or they build up a spreadsheet of test cases that they manually run through the pipeline. Some companies outsource filling out the spreadsheet. However, in any of these cases, you end up with a very slow and expensive process for evaluation.
At one point, we did this too. Gentrace is the result of a pivot; it was an internal tool we used to automatically grade new PRs as developers shipped changes to generative pipelines that other people thought might be useful.
Gentrace makes pre-production testing of generative pipelines continuous and nearly instantaneous. In Gentrace, you:
- Import and/or construct suites of test data - Use a combination of AI and heuristic evaluators to grade for quality, hallucination, safety, etc - Use our interface to correct automated grades or add your own (yourself or a member of your team)
Gentrace integrates at a code level for evaluation, meaning we test your generative AI pipeline the way you would test normal code. This allows you to test more than just prompt changes; for example, you can compare models (eg Claude 2 vs GPT-4 vs GPT 3.5 vs Llama 2) or see the effects of additional chained steps (”Rewrite the previous answer in the following tone:”).
Here’s a video overview that goes into a bit more detail: https://youtu.be/XxgDPSrTWIw
In production, Gentrace observes for speed, cost, and data flow. It also shows real user feedback as well. We do this by integrating via our SDK at a code level; Gentrace does not proxy requests.
Soon, we’ll allow you to convert production data into test cases, allowing customer support to turn bad production generations into “failing tests” for AI teams to make pass.
We process interim steps and multiple outputs as well, helping evaluate agent flows / chains where the “last output” isn’t always the only thing that matters.
There’s been a lot of observability tools published recently. We differ from those by focusing more strongly on blending observability with strong evaluation and by using an SDK rather than a “man-in-the-middle” approach to capturing data (ie Gentrace can be down and your request to OpenAI will still succeed).
Within the evaluation landscape, we differentiate by integrating with code (see above for benefits) for capturing generative outputs and by providing a customizable UI workflow for building evaluators. In Gentrace, you start with off-the-shelf automated evaluators and then customize them to your specific task. You also build and run new evaluators on old generative outputs. Finally, you easily override automated evaluators and/or blend automated evaluation with evaluation by humans on your team.
We also focus on being suitable for business use. We are SOC 2 Type 1 compliant (Type 2 coming shortly), have robust legal documentation around data processing, security, and privacy, and have already passed several vendor legal and security reviews at large technology companies.
Our standard usage-based pricing is available on the website: https://gentrace.ai/pricing
