What news means here
News here is not a release feed. Each piece starts from a change — a project that renamed and rebuilt itself, a listing that stopped showing papers, a paper claiming a problem people had given up on — and works back to what it means for the code you run on Monday.
The five articles below are grouped by the question each one answers.
The infrastructure that decides what you see
A preprint is not published into a vacuum. Two pieces take arXivLabs apart: the framework third-party tools must build inside, and what its cs.CL listing page tells you when it reports no papers.
- What arXivLabs Actually Is: Inside the Infrastructure Behind AI Preprints — the framework, the partners it admits, and the gatekeeping that comes with it.
- What arXivLabs Actually Is — And Why the cs.CL Listing Page Has No Papers to Report — why an empty listing says more about the pipeline than about the field.
Open-source stacks that replace a subscription
Two scales of doing it yourself: tools that cover most of what a paid subscription does, and one server that swaps models without touching your application code.
- Seven Open-Source Tools That Can Replace Your AI Subscriptions — what each one covers, and the gaps to expect.
- OGX, Formerly Llama Stack: Inside the Open-Source Agentic API Server That Swaps Models Without Rewriting Code — the rename, the architecture, and which abstraction to adopt.
World models, read in order
World models went from curiosity to plausible dependency in two years, which makes the literature hard to enter cold. This path walks Dreamer through to Genie in the order the ideas build on each other, not the order they were posted.
- From Dreamer to Genie: A Curated Path Into World Models for Engineers — the reading order, and where the claims get thin.
How to read this coverage
Every article states the contribution before the result, links the artifact, and flags what did not reproduce. If a piece points at a repository, read the open issues before the README. For paper-by-paper analysis rather than releases, the research digest guide is the other entry point.
