LLM products are creating a flurry of bad experiences in their rush to hit the market quickly. But Petr and his team have been demonstrating since day one just how serious they are about doing this job with outstanding designs. I've been following them for over a year now and I highly recommend them to everyone. I'm certain they're going to reach fantastic places.

Cool! Does this use Langchain under the hood? I wonder how OpenAI's Assistant API compares to your offering.
Petr Brzek
Hello @mikias, we don't use Langchain on the backend, but we support Langchain, so it's possible to use Langtail with Langchain. https://langtail.com/docs/proxy/... As for the OpenAI Assistant, we think they are great, and we are planning native support for them in Langtail. That said, we think there's value in offering a compatible Assistant API but with more flexibility and customization (like, for example, supporting different LLM providers).

Ever since I have known @petrbrzek, he and his team has always built tools you want to use - attention to detail is their brand. And current state of LLMs can really use a debugging & testing workbench :).
Ryan Hefner
@tomaskafka We like to think so! We've been obsessing over every detail of Langtail in preparation for this launch. It isn't perfect, but we think it's the best UX out there today. 🙂
Petr Brzek
Thank you, @tomaskafka, for the nice comment. I appreciate it. ❤️
Martin Duris
@tomaskafka Thank you Tomas!
