zswap and zram are fundamentally different approaches with different philosophies. If in doubt, use zswap.
FINAL STATUS (2026-10-21): the CVE-2026-109618 / CVE-2026-109619 memory-corruption class shipped patches 2026-10-21. On the patch, that class is closed: the cached-pointer chain dies at the addref and the serialize-state path is a memory-safety bug, not code execution. Two session-handling flaws survive on…

The following pictures show $n$ unit squares packed inside the smallest known square (of side length $s$). If a pictured packing has multiple numbers in its label above, the picture represents the largest; each smaller is represented by removing any square. For the $n ≤ 324$ not pictured, the trivial packing (with no…
Opus 5 is a step change improvement for the Opus tier powering long-running agents while delivering improvements in coding and professional work.
An ever-increasing volume of debug investigations, document writing, and code is written by robots. This has created a new etiquette question when working with a team - when is it OK to forward the output of an AI to another human to read?
Our first open-weights model: multimodal, Mixture-of-Experts, with controllable reasoning effort. Available to fine-tune on Tinker.
Starting June 1, your Copilot usage will consume GitHub AI Credits.
We are all having to keep revising upwards our assessments of the mathematical capabilities of large language models. I have just made a fairly large revision as a result of ChatGPT 5.5 Pro, to whi…
I don’t like people adding tracking stuff to URLs. Still less do I like people adding tracking stuff to my URLs.
The most powerful AI platform for enterprises. Customize, fine-tune, and deploy AI assistants, autonomous agents, and multimodal AI with open models.
Formats over apps.

We removed over 80% of Claude Code's system prompt for more advanced models. How to apply the lessons we learned to your own context engineering in Claude Code and with your own agents.
Some thoughts on Astra and newfangled long-horizon models.
The good educator insists on exercise, play, and plentiful sleep: "the great cordial of nature."
Announcement for the sunsetting of Gemini CLI in favor of Antigravity CLI, a more robust, agent-first platform designed to handle the multi-agent complexities of 2026.
Details on OpenAI’s contract with the Department of War, outlining safety red lines, legal protections, and how AI systems will be deployed in classified environments.
AI models like Claude talk in words but think in numbers. In this study, we train Claude to translate its thoughts into human-readable text.
In recent weeks, we pointed Mythos and other security-focused LLMs at live code across critical parts of our infrastructure. We share what we observed, the models’ strengths and weaknesses, and what the work around them needs to look like before any of it can scale.
We've been experimenting with running coding agents autonomously for weeks at a time.
OpenAI plans to test advertising in the U.S. for ChatGPT’s free and Go tiers to expand affordable access to AI worldwide, while protecting privacy, trust, and answer quality.
For those of you who haven’t seen, there were actually two “bombshell” QC announcements this week. One, from Caltech, including friend-of-the-blog John Preskill, showed how to do quantum faul…
