Vercel ships Workflow SDK 5: durable engine rewritten for agent loops, up to 25x lower overhead, end-to-end encrypted payloads by default and per-region runs

Vercel released Workflow SDK 5. It says the SDK has run over 4 billion steps and 700 million runs; v5 rewrites the engine to cut queue hops, taking a 1,020-step run from a 21-minute to a 3-minute median. Step payloads are encrypted with AES-256-GCM using a per-run key, Workflow infrastructure now runs in every Vercel Function region, and the same durability layer backs harnesses such as Pi and OpenCode.

OpenAI launches ChatGPT Wallet: dots agents can pay for you with network tokens instead of real card numbers, every purchase needs a biometric check, US Pro users first

On November 13 OpenAI announced ChatGPT Wallet, built with American Express, Mastercard and Visa, which lets dots agents complete purchases after the user approves them. At payment time the card network issues a token in place of the real card number, so neither the business nor the agent sees it; before each purchase the user reviews the items, total and card and confirms with Face ID or a fingerprint. It is rolling out now in dots to US ChatGPT Pro users aged 18+, alongside a Commerce Partner Playbook for businesses.

Lightning Labs Open-Sources pi402: Coding Agents Pay for Inference per Token in Bitcoin over Lightning, with No Accounts, API Keys or Cards

On November 12 Lightning Labs released pi402, an extension for the Pi coding agent with an embedded Wavelength Lightning wallet. When the agent calls a paid inference API, it pays automatically over L402 or MPP, and the proof of payment doubles as the API key, so there is no sign-up and no credit card. Sellers put Aperture v0.6.0 in front of an existing inference API and price per token with meterd or lightmeter. The whole stack is open source (MIT). Lightning Labs' example rate of 1 msat per input token and 2 msat per output token works out to about $0.80/$1.61 per million tokens at a bitcoin price of about $80,500.
