Long-form notes on the RL environments ecosystem — what changed, what to use, and how we check.
Stewardship consolidated under the Farama Foundation, GPU-native suites took over robotics, and half the famous names quietly died. A field guide to what's alive, what's archived, and what it means for your next project.
An honest ladder from CartPole to MuJoCo: the order to learn environments in, what each one teaches you, and what to avoid until you're ready.
From balancing a pole to Grandmaster StarCraft: the scores and milestones every new RL method gets measured against — and what each one actually proved.
Our methodology: live GitHub API checks, commit-history cutoffs, arXiv ID verification — including the 7 paper links we caught pointing at the wrong papers entirely.
