Summary

The Momo web inference library enables programmatic web exploration and data extraction using an autonomous agent. Users can initialize a client, specifying local and headless modes for background operation. The library supports single queries, follow-up queries, and parallel batch queries. For instance, a single query can find a specific paper on arXiv.org, with the agent autonomously browsing and performing actions like clicks and typing. Users can inspect the agent's final thoughts, actions, and screenshots, and save the full trajectory as an HTML file for review. Follow-up queries allow the agent to continue from its current state, such as extracting an author list from a previously found paper. Batch queries facilitate parallel execution of multiple tasks, like looking up citation counts for multiple authors on Semantic Scholar using several workers simultaneously.

Key takeaway

For AI Engineers building data pipelines or research tools, the Momo web inference library offers a robust solution for automating complex web interactions. You can programmatically extract structured data from multiple websites, such as academic papers or author citations, significantly reducing manual effort. Consider integrating this library to streamline data collection and validation processes, especially for tasks requiring sequential or parallel web navigation and information retrieval.

Key insights

The Momo web inference library automates web interaction for data extraction and exploration.

Principles

• Autonomous agents can browse and interact with websites.
• Agent trajectories are inspectable and reproducible.

Method

Initialize a Momo web client, define queries (single, follow-up, or batch), and execute using client.run, client.continue_on, or client.run_batch, specifying max steps and parallel workers.

In practice

• Automate data collection from multiple web sources.
• Extract specific information like author lists or citation counts.
• Review agent actions via saved HTML trajectories.
