Anthropic AI Model Finds Flaws in Tough-to-Crack Encryption Algorithms (6 minute read)

Claude Mythos Preview found flaws in a watered-down version of an algorithm for Advanced Encryption Standard (AES), a ubiquitous protocol that protects web traffic, wireless networks, data storage, and many other technologies. Anthropic claims the assault was 200 to 1,000 times faster than what previous human research had managed to do. The attack was devised almost entirely autonomously - the model needed aid as it originally believed the problem was impossible. Claude Mythos Preview worked on the problem for about a week before engineering its attack, and two human researchers worked for nearly a month to verify that the method appeared correct.

Why haven't organoids solved all of drug discovery? (33 minute read)

Organoids are clumps of human cells that show some type of organ-specific function. In theory, they seem like a good tool for drug discovery, but the reality is that the technology is still not reliable enough. There are many people working to fix the issues with organoids, but they are still methods in progress. Organoids have not dramatically altered medicine yet, but they have already been used for some unarguably useful things.

The Orchestrator's Tax (17 minute read)

Every token in the orchestrator's context is competing for its attention. The real value of a subagent is what it keeps out of that context. Subagents should be treated as a tool for protecting the orchestrator's working memory, offloading reasoning it doesn't need to hold onto. Doing this well means giving the orchestrator explicit ground rules for when and how to delegate.

MCP 2026-07-28 is live (2 minute read)

MCP 2026-07-28 is the largest update to the protocol since launch. It is now easier to deploy and scale remote servers. MCP is now stateless, so it can be deployed on serverless and edge infrastructure, or scaled horizontally behind any load balancer. There is now a formal path to extend the protocol.

The AI Future Is for Everyone (6 minute read)

As AI continues to improve, the question isn't whether superintelligence will exist, but who will have access to it. The technology could be centralized and restricted to a few institutions, or it could be used to empower everyone. The notion that AI is such a threat that the only safe path is an extreme concentration of power seems dangerous. Historically, hoping that an absolute power will benevolently provide for humanity if sufficiently enlightened hasn't led to safe or positive outcomes.

A Backlash Against Anthropic Is Brewing in Silicon Valley (11 minute read)

Anthropic has drawn criticism after releasing tools on the market that compete with those offered by partner companies. For example, Claude Design directly competes with offerings from partner design company Figma. Anthropic's data retention policies have also been criticized, but the company has pledged it won't use conversation data from Fable and Mythos - but not other models - to train new models. Researchers are calling for more transparency in AI systems.
