The Problem

Image Credits: Smooth

Although browser agents are becoming a reality, the team found that existing solutions are:

  1. Too expensive Usually require large models - can easily end up costing a few dollars even for simple tasks.
  2. Too slow Can take way too long to complete - e.g. 4 min to book a flight.
  3. Unreliable Even when provided with detailed instructions, they can struggle to complete the task.

LLMs may be exceptional at advanced math, but they still struggle to book a flight.

The Solution

They found that if you combine small and efficient models with a carefully curated context design, you can get higher reliability while also getting human-speed navigation and a huge cost reduction!

They packaged Smooth in a super-easy-to-use API with instant browser spin-up, custom proxies, persistent sessions, and auto-CAPTCHA solvers. Their goal is to give you this infrastructure so that you can focus on what's important: building great apps for your users.

Smooth is infinitely scalable, production ready, and secure. You can get started for free and run browser tasks in just 4 lines of code.
