Microsoft on April 23 launched an "Agent Mode" — dubbed "vibe working" — that gives its Copilot assistant the ability to take direct action inside Word, Excel and PowerPoint. The feature is being made the default experience for Microsoft 365 Copilot and Microsoft 365 Premium subscribers and is also available to Personal and Family plans. Built on improved foundation models with stronger instruction following and multi-step reasoning, Agent Mode can draft and rewrite text in Word, make formula, table and visualization changes in Excel, and refresh slides in PowerPoint while preserving company templates. A real-time sidebar shows every step Copilot takes, and Microsoft cites early customer metrics showing large bumps in Excel engagement, user satisfaction and retention. The rollout follows criticism of previous, more passive Copilot integrations and comes with controls to review or turn off changes; admins will still face deployment and governance decisions as the assistant becomes more proactive inside corporate workflows.

OpenAI on April 23, 2026 launched GPT-5.5, its newest base model designed to execute multi‑step, agentic tasks across coding, computer use, knowledge work and early scientific research. The company said GPT‑5.5 is faster, more token‑efficient and sets new benchmark scores versus prior OpenAI releases and some rival models. It is rolling out immediately to paid ChatGPT and Codex tiers (Plus, Pro, Business, Enterprise) with two variants — “Thinking” and a higher‑accuracy “Pro” — while API access is being staged pending additional safety work and partner testing. OpenAI emphasized expanded safety measures, third‑party red‑teaming and stricter classifiers for cybersecurity risks even as analysts note a rapid cadence of model releases and intensifying competition from Anthropic, Google and others. OpenAI also flagged commercial implications: gains in per‑token latency and Codex token efficiency that could lower cost per task despite higher list pricing for some 5.5 offerings reported by outlets. The company positions GPT‑5.5 as foundational to a future unified desktop “super app” that would combine ChatGPT, Codex and browser agents for sustained, autonomous workflows.

At Google Cloud Next in Las Vegas on April 22-23, 2026, Alphabet unveiled a major push across AI hardware and enterprise software: eighth-generation tensor processing units split into two purpose-built chips — TPU 8t for model training and TPU 8i for low-latency inference — and a unified Gemini Enterprise Agent Platform to build, run and govern AI agents. Google touted up to roughly 3x faster training and an 80% improvement in performance-per-dollar for inference versus prior generations, larger on-chip SRAM on the inference part (cited at 384MB), and superpod and cluster scaling capabilities (superpods of ~9,600 chips and architectures intended to interconnect far larger fleets). Design partners named include Broadcom and MediaTek, with reports of talks with Marvell to diversify suppliers; customers and partners cited include Anthropic, Meta and national labs. Google also announced tools such as Workspace Studio, Agent Designer, a 200+ model Model Garden (including Anthropic models), an A2A protocol for agent-to-agent communication, and a $750m fund to accelerate enterprise adoption. Google said it will continue to offer Nvidia hardware and is collaborating on networking improvements.

Meta-owned Instagram has begun testing a new standalone app called Instants that focuses on ephemeral, single-view photos and short videos. Rolled out in select European markets — notably Spain and Italy — the app forces content capture via an in-app camera (no uploads or edits), allows optional text, and restricts items to a single view or automatic expiry after 24 hours. Users can share with mutual followers or their Close Friends list, and the same Instagram credentials and friend lists work across Instagram and Instants. The company says it is exploring multiple versions and will listen to user feedback; availability currently spans iOS and Android in test regions but no U.S. launch date has been announced. Observers note Instants borrows core mechanics from Snapchat, BeReal and Locket and represents Instagram’s latest bid to recapture low-pressure, private sharing among close friends amid pressure from rival apps and changing user behaviour.

X announced on April 23, 2026 that it will retire its Communities feature in May after concluding the forum-like groups were little used and generated disproportionate moderation work. Head of Product Nikita Bier said Communities were used by under 0.4% of users but accounted for about 80% of spam reports, scams and malware complaints. X told Community admins they should move members into the app’s revamped group-chat offering, XChat, which supports joinable public links and currently holds up to 350 people with plans to expand to 1,000 or more. X is also steering users toward Custom Timelines — AI‑driven, topic-based feeds powered by Grok and available to Premium subscribers — as a way to surface focused content. The company gave administrators a migration window in early-to-late May 2026, with initial shutdown timing set for May 6 and some groups allowed to transition by May 30. X framed the change as a strategic shift away from slow forum-style experiences toward real-time chat and AI-curated feeds as it accelerates product launches.
