RAG system that skips HTML parsing entirely!
PixelRAG is an open-source visual RAG framework that renders documents as screenshots instead of parsing them into text.
Most RAG pipelines start by converting HTML to text. Tables flatten into unstructured rows. Charts disappear. Layout context is gone before the LLM ever sees it. The paper measured this directly: HTML-to-text conversion accounts for 36.6% of retrieval failures on SimpleQA.
PixelRAG skips that step entirely. It renders pages as screenshot tiles using Playwright, embeds those tiles with a fine-tuned Qwen3-VL-Embedding model, builds a FAISS index, and passes retrieved images directly to a VLM reader. No text abstraction in between.
Benchmarked across six datasets against the strongest text-based baselines:
- SimpleQA: 78.8% vs 71.6% (+7.1 points)
- NQ-Tables: 48.8% vs 42.5% (+6.3 points)
- EVQA: +15.5 points
- LiveVQA: +11.3 points
One honest caveat from the authors: this requires Qwen3-VL-4B class models or larger to see the benefit. Smaller models trail text retrieval. The authors also recommend using PixelRAG as an enhancement layer alongside existing text systems rather than a full replacement.
Ships with a pre-built Wikipedia index covering 8.28M articles across 28.1M screenshot tiles. A Claude Code plugin lets Claude take screenshots of any URL and reason over the visual content directly.
Key capabilities:
• Renders web pages, PDFs, and images as screenshot tiles via Playwright
• Fine-tuned Qwen3-VL-Embedding model for visual retrieval
• FAISS index for fast vector search
• Pre-built Wikipedia index: 8.28M articles, 28.1M tiles
• 3x token cost reduction via image compression
• Claude Code plugin for direct URL screenshot and visual reasoning
• LoRA fine-tuning support via pixelrag-train
100% open source.

This is quite a good article on how the cubic formula works, and particularly how root-finding is connected to symmetries (key background for understanding the impossibility of a quintic formula)

The Founding Fathers blended Enlightenment ideas, history, and experience to craft a stronger US government than the Articles of Confederation. The Declaration of Independence in 1776 launched self-governance. #USHistory# #FoundingFathers#
Riley Gaines is ripping a USA Today column about Caitlin Clark, calling it "insane" and "defamatory."
Gaines blasted columnist Nancy Armour for comparing Clark's fan base to the 1955 lynching of Emmett Till, saying there is "zero credibility" behind the claims.
Gaines says she hopes Clark pushes back, arguing the article crossed the line.
From @TheAthletic: Indiana Fever guard Sophie Cunningham doubled down Wednesday on comments she made in a recently published ESPN article, saying it’s “common sense” to bar transgender athletes from competing in women’s sports.
Congress's powers are limited to those specifically enumerated in Article I, Section VIII. Any action beyond these powers is unconstitutional, a principle essential for limited government and protecting freedom. #USConstitution# #LimitedGovernment#
.@jonmalexander shared some of his insights from his article on Nick Caley:
-“he’s going to be honest.”
-“he felt like he was over ambitious” before realizing personnel wouldn’t fully allow (tight end injuries, young WRs etc)
-thought he’d bring Rams concepts but realized coaches and/or personnel more fit the Patriots offense
-“CJ Stroud might’ve been expecting one thing, his receivers might’ve been expecting another.” on young WRs & Kirk struggling
-“Schultz knew the offense more than anybody”
-“he seemed very confident they will have an improved season, he’s learned a lot, adjusted.”
