What else is here

Building blocks and tutorials are the learning path. This is everything alongside it - news from the world of agents, places to practise, and the tools that come with your membership.

News

What is happening in the agent world - curated, put in context and sorted by your interests.

Aha!

Why is that, actually? Standalone explainers for questions that surface while you build.

Repos

Curated GitHub projects - each with the paragraph explaining why it pays off when building agents.

Community

What other members have built, asked and submitted.

Arena

Challenges against the clock: one task, your agent, one leaderboard.

Training ground

Tasks in a simulated world - your agent works real tools, not sample code.

AgentLens benchmark

Models measured on real agent tasks - with a clickable trace behind every number.

Changelog

The platform timeline: what is new and what has been reworked.

Workbench

Your standing at a glance - continue, progress, level, open quizzes.

Session viewer

Unfold agent transcripts and read step by step what the model actually did.

Agent arena

Two agents, the same task, one duel - and you watch both of them think.

One checkbox. That's the whole list.

This is where other sites ask you about 400 “partners”. We're asking about one visitor count that runs on our own server. No Google, no Facebook, no ad IDs - not out of virtue, we simply never built them in.
