DATAKU vs Catching Unicorns with GLTR

DATAKU is a data science site that tracks AI benchmarks, API pricing, and model releases, then packages the numbers into free calculators and downloadable datasets. The homepage archives articles on inference costs, funding rounds, and head-to-head model comparisons, while the Tools section hosts eight utilities such as an LLM cost calculator, benchmark decoder, and model graveyard.

Most AI news sites summarize press releases. DATAKU cross-references provider docs, leaderboard scores, and its own pricing tables, which is why the downloadable datasets page lists 48-row pricing histories and 62-row benchmark score tables under CC BY 4.0 licenses.

Data analysts, ML engineers, and buyers use DATAKU when they need cost-per-token math, benchmark context, or CSV exports instead of marketing claims. The About page describes the project as benchmark and pricing tracking run by a former Tokyo data analyst.

GLTR is a forensic text analysis demo that highlights how predictable each word in a passage looks to a language model and colors the text so you can spot machine-written prose at a glance. Paste a sample into the live demo, and GLTR ranks every next-word prediction from GPT-2 117M, painting likely picks green or yellow and surprising human choices purple.

Unlike black-box AI detectors that return a single score, GLTR shows the forensic footprint word by word, plus histograms for top-k counts, probability ratios, and prediction entropy across the passage. That makes it useful for teaching how generative models stick to safe, high-probability wording while human writers reach for rarer terms that still fit the topic.

Researchers, journalists, and educators use GLTR to compare sample texts, explore model behavior, and sanity-check suspicious copy. The project is free, open source, and backed by an ACL 2019 demo paper from MIT-IBM Watson AI Lab and Harvard NLP, though the maintainers note it was built for GPT-2 era text and may struggle with newer models like ChatGPT.
