Honestly I thought you guys had launched already (and didn't know you were a part of YC), been aware of you guys for years now it seems. Congrats on the launch! Hope the twitter issues aren't causing you guys too many problems. Normally I'd send this as a DM or email, but I think it could be useful for others to learn about how to use your service/the limitations of it. A couple weeks ago I made a search for: In earl…

I think I found it! Unfortunately we do not include tweets in our search index

> TLDR LLM training runs are significant stress-tests of an overall fault tolerance of a large computing system acting as a biological entity.

I think you guys nailed the "selling shovels during a gold rush" as the biggest issue with LLMs currently is their reliability/hallucinations, not their capabilities. If I can use websets to back up LLM responses through your API, that's super useful. Since you were part of YC 21, could you share a bit about your pivots/product iterations you went through over the last 4 years?

Mission of Exa has always been to build much better web search. The evolution has been: - 2022: Consumer-facing embeddings search (back when we were known as Metaphor) - 2023: Web search for AIs - once the AI ecosystem heated up, we made a business out of web search + crawling API. This is still our primary business. - Now: Websets, a useful product built on top of our search tech If you're curious, our company right…

It must be heartening for a startup trying to build the best general search engine in the world to know that Google has absolutely no interest in competing with you.

Earlier quoted context omitted.

We find supporting references when evaluating the search criteria / enrichments of each result, and you can view these citations https://imgur.com/dsGK5dS

Right, I saw that. ChatGPT does the same. My question is how you can confirm the entity you're referencing in each source is actually the entity you're looking for? An example I ran into recently is Vast ( https://www.vastspace.com/ ). There are a number of other notable startups named Vast ( https://vast.ai/ , https://www.vastdata.com/ ). I understand Clay, which your Websets product is clearly inspired by, does a f…

Deduplication is mainly driven by LLMs with search results as context. Our entity resolution works well because Exa’s main business is crawling and indexing the web at scale, and we can control how we search across that within Websets.

As far as I know ChatGPT’s search is primarily a wrapper around another company’s search engine, which is why it often feels like it’s just summarizing a page of search results and sometimes hallucinates badly.

Thanks for the info. That makes sense.

Looking forward to trying out the product more when I have a moment.

Did my favorite search query, and the result were pretty bad, as expected:

"robotics servo motors with two-directional control for under $100"

1. https://mjbots.com/ - their motor are $1369. FAIL.

2. https://www.pololu.com/ - this is huge store, but they do have some motors like that. Pass, but wish it linked to specific page and not top top-level one.

3. dh-robotics.com - no prices, but some products on open market are few K$. Likely fail as well.

4. https://www.robotarticulation.com/ - The product is not for sale (early beta), and it looks likely much more than $1K. FAIL.

5. https://www.lynxmotion.com/ - another huge store, most two-directional motors are expensive but there are some under $100... Pass, but wish it linked to specific page and not top top-level one.

I was so excited for this, but sadly it doesn't work at all, not even UI feedback for the error:(

The UI showed literally no change. So I checked and the console shows:

``` Try: 14 Not Found 681-7df1b139fa2dc9f0.js:14:3379 Try: 15 Not Found 681-7df1b139fa2dc9f0.js:14:3379 Try: 16 Not Found 681-7df1b139fa2dc9f0.js:14:3379 Try: 17 Not Found 681-7df1b139fa2dc9f0.js:14:3379 Try: 18 Not Found 681-7df1b139fa2dc9f0.js:14:3379 Try: 19 Not Found 681-7df1b139fa2dc9f0.js:14:3379 Try: 20 Not Found 681-7df1b139fa2dc9f0.js:14:3379 Gave up after 10 seconds. 681-7df1b139fa2dc9f0.js:14:3379 filteredSuggestions Array(3) [ {…}, {…}, {…} ] 681-7df1b139fa2dc9f0.js:14:3379 ```

Also your table doesn't fit in the viewport so I can't see the results.

Firefox Ubuntu.
