Redesigning Source Control at Anthropic (14 minute read)
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 (12 minute read)
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 (13 minute read)
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.

OpenAI Engineer Arrested over Alleged Conference Room Bugging (5 minute read)
Federal prosecutors charged an OpenAI engineer with using or attempting to use a device to intercept conversations after a concealed recorder was found in an executive conference room. OpenAI says it referred the discovery to the FBI and has found no indication that model weights, source code, or customer data were improperly accessed or taken.

Are Harnesses Worth the Cost? (20 minute read)
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.

The “Alien” Economics of AI Monetization (6 minute read)
Two-thirds of the Forbes AI 50 companies use some form of usage-based pricing as variable AI costs push businesses toward hybrid subscriptions, credits, and outcome charges. Examples from AI companies show why spending controls, flexible packaging, measurable customer value, and pricing pages readable by both people and agents are becoming part of the product.
