DATAKU vs Delve AI

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.

Delve AI turns your website analytics, CRM data, and social audience signals into buyer personas, digital twins, and synthetic research panels you can chat with. Marketers use it to segment audiences, run surveys against synthetic users, and get channel-specific campaign recommendations without commissioning traditional focus groups.

Generic persona templates give you demographics on paper. Delve AI pulls from first-party and public data sources to auto-segment your actual visitors and competitors, then lets you interview those personas as digital twins. The gap is price and complexity: combo bundles start at $317 per month, which fits agencies and mid-market brands more than solo founders testing product-market fit.

Over 45,000 brands and agencies use Delve AI according to its homepage. Gartner featured it in the 2026 Hype Cycle for User Experience report, and the platform holds a 4.8 rating on G2 and 5.0 on Capterra.
