The solution to most problems in science is more science. We need the best researchers working on security so we can have our cake and eat it: the pace we want and the safety we need.

Companies will invest more in AI when they're paying for the value delivered vs usage. It's about charging for outcomes not tokens. @btaylor in conversation with Saul Van Beurden from @WellsFargo.

A conversation about personal agents, retail, and payments with @btaylor and Mike Storiale, SVP, AI Technology & Transformation, @synchrony

At Bared Footwear a 20-minute call about how a shoe fits is time well spent. A 24-hour wait for a return label isn’t. Their AI agent now handles the quick fixes on chat and email, so the people who know every style can spend their day talking shoes. Read about the partnership: sierra.ai/customers/bared-fo…

Voice agents can handle increasingly complex calls, but often fail on the simple details. τ-Entity is a new benchmark measuring whether an agent can correctly capture details like names, phone numbers and email addresses, recognize when it might be wrong, and repair the mistake.

How well do voice agents work across languages — and how natural do they sound? Today we’re introducing 𝜏-i18n (pronounced tau-internationalization), which extends 𝜏-Voice to five more languages: Spanish, Brazilian Portuguese, Hindi, Korean, and Mandarin.

We've partnered with @stripe so customers can get answers and pay in the same conversation, with no transfer and no payment link. @CedarNY is one of the first to take phone payments through the integration. When a patient calls Cedar's agent Kora about a bill, they can ask about a charge, pay securely on their keypad, and get confirmation without leaving the call — and 71.3% of those calls end in a successful payment. "Medical bills create a moment of real anxiety for patients, and historically, getting a question answered and actually paying the bill have been two separate, disconnected steps. Working with Sierra and Stripe, we've closed that gap. A patient can call confused about a charge and leave the conversation with clarity and a resolved balance, in the same call." — Dugan Winkie, Chief Strategy Officer, Cedar Read more: sierra.ai/blog/from-conversa…
