How startups are building faster, more capable agents with GPT-5.6 through smarter model selection, API controls, and programmatic tool calling to cut costs and improve reasoning across multi-agent workflows.

Explains when LLM predictions can substitute for human outcomes in A/B tests, outlining surrogacy and comparability conditions, calibration methods, and the design-by-assumption limits of identifying treatment effects.

A technical examination of when LLM-predicted user responses can substitute for human outcomes in A/B tests, highlighting surrogacy and comparability conditions, calibration strategies, and the limitations of design-based identification.

Explains how BigQuery Graph with in-place measures unifies metadata grounding, relationship mapping, and graph traversal to enable trusted agentic workloads, with no-ETL mapping, visual graph modeling, Conversational Analytics, and native Looker integration.

BigQuery Graph with in-place measures unifies governance, relationship mapping, and multi-hop reasoning to power trusted agentic workloads by mapping existing tables to a property graph and enabling Conversational Analytics with Looker integration.

A concise guide to when to use ser versus estar in Spanish, covering conjugation, common uses via the DOCTOR and PLACE mnemonics, and practice challenges.

Certificate Transparency Monitoring is generally available, reducing alert noise by using an early SPKI-based identifier to suppress Cloudflare-issued certificates and surface only unexpected, external certificates.

A technical analysis of how a total solar eclipse across Iceland, Spain, and Portugal triggered measurable dips in Internet traffic, using Cloudflare Radar HTTP data, five-minute buckets, and baseline comparisons to quantify the relationship between solar obscuration and online activity.

Certificate Transparency Monitoring gets a noise-reduction upgrade by using a SPKI-based, early, and consistent spki_sha256 key to deduplicate Cloudflare-issued certificates and surface only externally issued alerts.

An in-depth technical look at how a total solar eclipse across Iceland, Spain, and Portugal caused a measurable dip in internet traffic, tracked by Cloudflare Radar with five-minute HTTP metrics and obscuration timing.

A framework for selective unlearning that identifies low-influence training points via influence functions to reduce computational costs and improve data privacy in machine learning.
