Hey Knowledge Agent, how can I cut repeat questions by 16% and token-use by 80%? (Sponsor)

[Consulting knowledge layer…]

Your team solves the same problems in Slack every week, but the answers never reach the docs your AI reads. So when the next person asks, the agent serves last quarter's version, and the cycle repeats.

Guru fixes the source before anyone asks:

✅ Turns resolved threads and tickets into drafts your team approves.

🗣️ Verifies/unverifies content on rules written in plain language.

🤖 Keeps stale content out of every agent's context.

🧠 Serves the verified layer to any AI tool over MCP.

Teams have seen: 80% less token use, 16% fewer repeat questions, and 96% of searches end with the AI answer.

Stop answering the same question twice.

'It's offensively cheap': How solar power is quietly becoming bigger than nuclear (9 minute read)

Solar power will likely provide 10% of the world's power by the end of the year. Solar electricity is the fastest-growing source of new electricity in history as it has become unbelievably cheap. China is still the world's biggest solar power producer by far, but the installations in the US are skyrocketing. Even with tariffs, solar is still one of the cheapest sources of new power in the US, and it is getting built regardless of political lines.

Working with academic communities to build scientific understanding (12 minute read)

OpenAI has announced three new discoveries in mathematics, computer science, and physics. For the math result, which is about harmonic analysis, the AI lab will release the AI output, so researchers are free to organize their own efforts to explain the result. OpenAI will form an external group of collaborators to explain the computer science result, which is about complexity theory, and will make the AI output publicly available. The lab will also form an external group of collaborators for the physics result, which is about quantum field theory, but defer to them on the release of the materials.

How the Claude Code team does code review (18 minute read)

Claude writes about 90% of the code in Claude Code. This post explains how the team reviews the code at the volume its agents produce. The team moved most of the reading in the review stage to machines, optimized for human time and attention, and invested heavily in making it fast and easy to undo mistakes. This resulted in merged pull requests to Claude Code's codebase more than doubling while the share that had to be reverted fell by more than 40% between June and September.

The Counting House (49 minute read)

The Counting House pattern adds AI to systems that handle large volumes of human work, notably customer service departments. It can be used to control and improve costs, quality, and human ramp-up time using comparatively cheap AI models. A Counting House uses classic data science and engineering to put lower-tier models on hardened rails to support human workflows. It allows teams to measure and report how well models do against their human counterparts.
