Vectorize

What is Vectorize?
Vectorize builds Hindsight, a data science platform for open source agent memory aimed at teams shipping AI agents that need persistent, per-user context. Hindsight stores experiences, recalls them across sessions with four parallel search paths, and reflects on patterns so agents learn from failed tool calls instead of repeating mistakes. The core is MIT licensed, runs from a single Docker command, and ships a Python SDK, REST API, and built-in MCP server.
Most agent memory stacks stop at vector lookup or RAG-style retrieval. Hindsight runs dense vector search, BM25 keyword matching, graph traversal, and temporal causal search in parallel, then merges results with token budgets rather than a fixed top-K count. That gives predictable prompt size and API cost, which retrieval-only competitors typically skip. Vectorize reports 94.6% on LongMemEval and ranks first on the BEAM agent memory benchmark, scores it positions against flat vector stores.
Developers wiring memory into Claude Code, Cursor, or custom agents via MCP are the core audience, along with teams that want managed Hindsight Cloud with pay-as-you-go token billing. Customer logos on the site include NVIDIA, Groq, and Electronic Arts, and Vectorize cites 15,000+ developers building with Hindsight globally.
DATAKU

What is DATAKU?
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.
