Show HN: Smooth – Faster, cheaper browser agent API

Super impressive demo. Seems a lot faster than alternatives. How did you achieve that?

Do you support writing deterministic extractor scripts? I want to use an agent like this primarily as a way to help me write and refine deterministic extraction scripts, rather than involving the LLM for every iteration. If you don't yet, would you be up for talking about it? (And if so, should I email you or schedule an enterprise demo)?

Hi, thanks for sharing.

My main concern with these browser agents are how are they handling prompt injection. This blog post on Perplexity's Comet browser comes to mind: https://brave.com/blog/comet-prompt-injection/.

Also, today Anthropic announced Claude for Chrome (https://www.anthropic.com/news/claude-for-chrome) and from the discussion on that (https://news.ycombinator.com/item?id=45030760), folks quickly pointed out that the attack success rate was 11.2%, which still seems very high.

How do you plan to handle prompt injection?

Really interesting work! I have two questions:

1.LLM-Ex

> We call this LLM-Ex.

Could you share more about the internal structure of LLM-Ex? Is it something like a fixed XML-style representation, or more of a free-form structure?

2.realized you don't need huge models to get reliable results

You wrote that > by applying these two principles religiously, we realized you don’t need huge models to get reliable results.

Intuitively, it feels like these principles alone wouldn’t completely remove the need for larger models. Could you explain how you arrived at this conclusion, and what kind of validation or experience led you there?

I just wrote a complex prompt and it did a good job. How do you do evals or testing of your project?

Is there a way to sign up without Google SSO?

So you're shamelessly selling spambots? The marketing here is wild... "proxy rotation"... "auto-CAPTCHA solvers"
