OpenAI sketches new agent stack: Decisions API, Agents API, and faster Computer Use

At DevDay, OpenAI showed new building blocks for agents: asynchronous tool calls, mid-turn steering (steer while the answer runs), WebSockets, UltraFast inference, and the Decisions API.¹ Ari Weinstein said Computer Use is “180 degrees different” today, and screenshots plus accessibility data, DOM, Playwright, and generated code speed up tasks.¹ Status: announced in the podcast conversation. Details and availability are vendor claims without independent verification.¹ If you build agents, plan for structured decisions with low latency, plus longer prompt caches and pre-warming.¹

White House accord: large labs commit to external audits and controls

A report says industry leaders signed a joint self-commitment with external audits, internal controls, and multilayer reviews. The US President called it “morally binding.”² The list of signatories and the note that Microsoft and Amazon did not visibly sign come from this source and are not officially confirmed.² If you deploy frontier models, prepare an external audit relationship and document your internal AI controls.²

ML early warnings for power grids during solar storms

Microsoft Research describes a system with 30–60 minutes of lead time and location-specific risks for 66,935 US substations.³ It detected about 80 percent of major events from 2020 to 2026. Reported are 76.5 percent hits at 10 nT/min, 81.2 percent at 20 nT/min, and 64.1 percent at 50 nT/min.³ If you work in grid ops or critical services in the US, feed such signals into readiness, alerting, and customer comms.³

Highlights for your workday

Build a claims-capable assistant with Amazon Bedrock Knowledge Bases: the Agentic-Retrieve-Stream API plans sub-queries, checks evidence, and returns answers with sources. A guardrail secures content binding to documents. Agentic retrieval means: the assistant plans and repeats fetches on its own.⁴ Google introduces Skills as reusable instructions and replaces Gems. You define your routine once and use it for recurring tasks.⁵ n8n shows a new agent with no code. Photos of sticky notes become tasks, receipts get logged, morning emails pre-sorted, controlled via Telegram.⁶

Tools and updates

• LangChain Managed Deep Agents 0.8 now accept requests via arbitrary webhooks. An example logs expenses when you forward a receipt by SMS. Requirement: Managed Deep Agents access.⁷
• Nemotron 3 Diarization in Transformers 5.18.0 separates speakers in real time and offline up to eight voices, ordered by arrival. Useful for meetings and call review. Speaker diarization means: “who spoke when.”⁸
• NVIDIA NeMo Relay logs agent steps in detail so you can spot detours and cut latency and token use. Requires NeMo Relay.⁹

Try it in five minutes

1) Open your preferred AI chat and paste this sample text: “CLM-100482: auto claim, status open, filed on 07/09/2026, current amount 14,250 USD. The revised estimate from 07/22/2026 replaces the fax version from 07/15/2026. Provisional payment from 08/01/2026 was canceled on 08/12/2026. Planned check issuance after approval of the revised estimate.”⁴ 2) Ask: “Was the estimate for CLM-100482 approved, and when will the check be issued? Answer only from the text and add a source bracket like [T1] after every sentence.”⁴ 3) Check the answer. Ask the AI to fix it if it adds content not in the text, or if any sentence lacks a [T1] bracket.⁴

Expected result: a short answer with 1–2 sentences. Each backed by [T1]. No extra assumptions.⁴ Check criterion: every sentence relies only on the sample text and carries a source bracket.⁴
