This looks great! Well done. My concern is that there's not a single mention of data privacy. Which is is a red flag for any one coming from an enterprise world. Get that sorted and I'd consider using your tool for actual work.

Hi - we encrypt everything at rest and use metadata to improve LLM performance. We don't yet have enterprise-grade data permissioning or compliance certificates like Soc2. Those will come in time.

And where are the keys stored?

do you use any agentic prompting techniques?

Yes definitely. We wrote a multi-step reasoning engine similar to o1. Depending on the route and depth in the chain of response, prompting techniques vary. The LLM router was pretty important to get right. On input: synthetic question enhancement has yielded positive results. Asking the right question is subtly important, and we find it is sometimes better to just slow a user down and help them improve their question instead of relying on multi-step reasoning from the get go. On output: checking answers via mixture of experts and other techniques is often necessary -- "truthful but wrong" answers are where some tricky gotcha's lie. Eval is hard.

One under-discussed feature of fast databases is that they are especially necessary in an agent-centric world. E.g. if you're running recursive SQL to pathfind towards an answer, it has to happen with minimal latency otherwise you break the user experience. Our interface looks like a spreadsheet and users mentally benchmark against spreadsheet-latency speed. They won't accept 20 second query response times they might get from their data warehouse.

Thanks for reporting! Taking a look now.

Hey do you mind removing this comment? Seems it might have caused us to be blacklisted?

This post was briefly flagged after that initial comment, which is what dioptre was referring to, not AdGuard. Phrasing was too ambiguous, hope that clears it up!

Does this use function-calling on the backend?

We use our own implementation of function calling orchestrated by chain-of-thought. The CoT allows us more granular control over the function calls, rather than zero-shotting and hoping the LLM selects the right functions.

We use Amazon’s key management service.

This makes zero sense

We thought there might be basic word filters that tripped the algorithm. “Scam” being the offending word here. (Turns out it was something else that tripped a flame war setting. Probably a comment that later got flagged by the mods.)

Anyway, fun fact: it turns out our domain used to be a scam erectile pills website!

It was in reply to a dishonest comment that was taken down. It's normal to use elevated rhetoric when correcting the record about a false idea being put forth and made public. Furthermore saying "probably because the CTO is a dick" to a random person online - in response to a question about why their startup is blacklisted - is definitely fair game . How many people have said "{insert CEO name} is a dick" on these fo…

I'm just a random guy here; if what I wrote wasn't helpful, disregard! Sorry about that.

TBF, however, random guys (and gals, and all that lieth betwixt and beyond) are who effect most of HN's moderation through votes and flags.

So if someone such as tptacek suggests that a comment goes beyond HN guidelines, it's generally worth consideration.
