Marker: Smart PDF Extraction with Hybrid LLM Mode

Problem

Standard OCR pipelines often miss inline math, split tables across pages, and lose the relationships between form fields.

Sending the full document to an LLM can improve accuracy, but it’s slow and expensive at scale.

Solution

Marker‘s hybrid mode takes a more targeted approach:

• Its deep learning pipeline handles the bulk of conversion
• Then an LLM steps in only for the hard parts: table merging, LaTeX formatting, and form extraction

Marker supports OpenAI, Gemini, Claude, Ollama, and Azure out of the box.

Qdrant: Fast Vector Search in Rust with a Python API

Problem

Building semantic search typically starts with storing vectors in Python lists and computing cosine similarity manually.

But brute-force comparison scales linearly with your dataset, making every query slower as your data grows.

Solution

Qdrant is a vector search engine built in Rust that indexes your vectors for fast retrieval.

Key features:

• In-memory mode for local prototyping with no server setup
• Seamlessly scale to millions of vectors in production with the same Python API
• Built-in support for cosine, dot product, and Euclidean distance
• Sub-second query times even for millions of vectors

PDF Table Extraction: Docling vs Marker vs LlamaParse Compared

Extracting tables from PDFs can be surprisingly difficult. A table that looks neatly structured in a PDF is actually saved as text placed at specific coordinates on the page. This makes it difficult to preserve the original layout when extracting the table.

This article will introduce three Python tools that attempt to solve this problem: Docling, Marker, and LlamaParse.
