MolmoWeb

What it does

Introducing MolmoWeb, an open visual web agent that navigates and completes tasks in a browser using screenshots alone, along with MolmoWebMix, the largest public dataset for training web agents.

We're releasing the full MolmoWeb codebase —the training code, eval harness, an annotation collection tool, a synthetic data generation pipeline, and the client-side code for our demo. The training code includes everything needed to customize MolmoWeb for specific applications. The annotation tool lets you record human task demonstrations, then fine-tune the model on that data. The eval harness lets you evaluate agents like MolmoWeb on popular navigation benchmarks such as WebVoyager, Online-Mind2Web, WebTailBench, and Deepshop. It doubles as a synthetic data gen pipeline as well—you can generate web browsing data using LLM- and VLM-powered agents with AxTree/screenshot input. We’re also…from allenai.org

We found some great tools online, but none reliably handled the entire process. We wanted an API that took a URL, crawled the pages in the URL, and gave us an easy-to-use, up-to-date markdown we could feed into our index. So, we released an open-source repo and an API that crawls and turns entire websites into a markdown with just a few lines of code The API handles: - Crawling without consistent sitemaps - Infra to handle running many crawling jobs - Proxying,…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
