ADD AUTHKIT TO YOUR EXISTING APP WITH ONE COMMAND

Your app needs authentication. That means installing an SDK, wiring up callback routes, configuring middleware, and getting the environment right. Or run one command: npx workos@latest install [4]. The WorkOS AI installer [4] detects your supported framework and adapts AuthKit to your existing project. What it does: * Installs the SDK * Creates authentication routes * Sets up environment variables, with post-installation validation enabled by default

REDESIGNING SOURCE CONTROL AT ANTHROPIC

Anthropic replaced Git with Scion after daily merges grew from roughly 2,500 to more than 30,000. The centralized system uses server-side commits, sparse checkouts, and layered caches, reducing its source control infrastructure's CPU and memory footprint by 200 times and freeing 25% of CI CPU capacity.

REWINDING THE EXPONENTIAL: HOW WE KEEP HARDWARE USAGE DOWN

Cloudflare's data pipeline handles roughly two billion events per second while hardware capacity grows more slowly than traffic. Product-specific schemas, zstd compression, later replication, earlier sampling, and aggregation have collectively deferred the equivalent of two and a half years of hardware expansion.

A YEAR OF FAST APPLY: THE PATH TO 10K TOKENS PER SECOND

Relace explains how it built a small model that applies code edits at a reported 10,000 tokens per second using high-quality merge data, LoRA fine-tuning, FP8 quantization, and speculative decoding. Its training pipeline filtered 200,000 candidate examples down to about 145,000, using a judge calibrated against 500 manually reviewed merges. Relace Apply 3 supports a 256,000-token context and multiple diff formats, although improving frontier-model edit accuracy could eventually reduce the need for specialized apply models.

HOW TO BE MORE AMBITIOUS: A TUTORIAL FOR HUMANS WITH MODELS

More ambitious AI use can mean pursuing higher-level outcomes, applying expert methods to raw data, or combining ideas from multiple fields. Practical examples show how to move beyond generating a quarterly slide deck toward identifying urgent decisions, testing assumptions, and validating results with independent tools.

OPENAI ENGINEER ARRESTED OVER ALLEGED CONFERENCE ROOM BUGGING

ARE HARNESSES WORTH THE COST?

In ten runs on one Java API service, a behavioral harness raised GPT-6 Luna's acceptance rate from three successes to ten, while GPT-6 Sol passed all ten runs with or without it. Harnessed Luna cost about 33% less per run than unharnessed Sol, but those estimates exclude harness maintenance and the unusually detailed brief limits how broadly the results apply.

WHAT GETS TOASTED IN POSTGRES

Postgres TOAST compresses oversized variable-length values and moves them into separate storage when necessary.

THE “ALIEN” ECONOMICS OF AI MONETIZATION

WHY THERE WILL BE MORE PRO RATA CONFLICTS

Early-stage funds increasingly exercise pro rata rights across multiple rounds as they grow, driven by outliers offering significant upside potential. The rise of secondary markets and financial vehicles like Fund of Funds and SPVs supports smaller funds in monetizing pro rata shares. Faster round pacing within a fund's investment period further contributes to potential pro rata conflicts.

ARR VS GAAP REVENUE | SPOTTING “ARR” LIES

Businesses need to stay honest about what ARR actually is. If ARR doesn't ultimately lead to revenue and cash, then it's a fake metric. Most companies need to redefine or evolve their definitions of ARR for the AI era. ARR should turn into GAAP revenue, and it shouldn't take a really long time for that to happen.

HOW TO GROW A MASSIVE BRAND (FULL 2026 MASTERCLASS)

A founder's account and a company's account don't need to publish the same things. This guide assigns the founder the beliefs, lessons, and experience of building, while the company explains products and launches. It also distinguishes posts that attract new people from posts that build trust or encourage a purchase. That gives teams a clearer way to judge results: a post meant to introduce the company should not be assessed only by immediate sales. Interested followers can then move into email or a community for a longer relationship.

OK, I MIGHT HAVE BEEN WRONG ABOUT BUILDING WITH A LEAN TEAM IN THE AGE OF AI

Chatbase is now at 40 people, and it plans to double its number of employees in the next 6 months. Building is now much easier, and the opportunity cost of not building more is huge. Companies that want to build more, grow more, and achieve more still need to hire because humans are still needed in many parts of the building loop. While this might change, it doesn't make sense to act like it isn't true right now.
