In this episode

• Sonnet's effort setting — Anthropic released Sonnet 5.5 September 28. Standard input/output rates remain $2/$10 per million tokens. Anthropic claims over 30% faster output and up to 30% lower task cost through token efficiency. Medium effort is the default in Claude and Claude Code; the API defaults to High. Compare completed tasks, corrections and effort settings, not model names alone.
• Apple's targeted-attack patch — iOS and iPadOS 26.7.1 fix CoreGraphics CVE-2026-86950. Apple says it may have been exploited against specific targeted individuals on versions before iOS 27. This advisory is distinct from iOS 27.0.1 Face ID restart repairs. Check Software Update for the supported release for your device.
• AMD buys closer ties — World Labs signed an agreement to join AMD. TechCrunch reports an $8.2 billion deal. Fei-Fei Li would join AMD as EVP and chief scientist. Closing is expected by year-end subject to approvals. The promise of widely accessible models does not yet specify release dates or usage terms.
• Pro's moving allowance — OpenAI’s Tibo Sottiaux announced the reopening of $200 Pro to new subscribers with usage equivalent to roughly half the API-dollar spend of the old plan. This is advance notice, not confirmation of live enrollment. He argues model efficiency will increase useful work and says the five-hour limit will not return. Workload and model choice affect the outcome.
• Checkout needs a yes — Shopify supports eligible checkouts through compatible Chromium browser agents. Buyer authorization remains required; new payment credentials cannot be supplied through the tools. After an ambiguous completion failure, agents should check the outcome before retrying to avoid duplicate orders.
