Approximate Labs

Boulder, CO

Independent research into the efficiency of reasoning.

We build compilers, benchmarks, and self-modifying architectures to enable System 2 thinking in Large Language Models. Moving beyond static context to active state management.

Lab History (2022–2024)

TabLib
Dataset

The world's largest open-source dataset of tabular data. 627M tables extracted for training Large Data Models.

HuggingFace ↗
Sketch
Tool

An AI code-writing assistant for pandas that understands data context via approximate summarization algorithms.

GitHub ↗
Julyp
Product

Data-focused AI assistant (formerly Tabby Chat and Julyp) backed by on-demand Jupyter Lab environments with dynamic installs, cached data pipelines, dashboards, and full iframe/canvas rendering.

TableGen
Product

Experimental smart spreadsheet where each cell runs an agent with row and column context. Agents execute in parallel to fill tables and enable fast data manipulation.
