Hyatt deploys ChatGPT Enterprise across its entire global workforce

Hyatt today rolled out ChatGPT Enterprise company-wide โ€” one of the largest hospitality deployments of OpenAI’s business product to date. Employees in finance, marketing, business development, real estate, product and engineering, and customer experience now have access to GPT-5.4 and Codex. Rather than going all-in on one embedded assistant, Hyatt has taken the approach of building a central data/AI layer first and letting staff choose among multiple models through it. Early wins include natural-language search on Hyatt.com and agentic tools for the group-sales team. A useful case study for any communications leader watching how large, legacy-heavy enterprises are actually operationalising AI.

Anthropic launches Claude Design โ€” and Figma’s stock takes a hit

Anthropic released Claude Design, a new product inside Claude that turns a written brief into polished mockups, decks, one-pagers and prototypes. You describe what you need, Claude builds a first draft, and you refine it by chatting, dragging sliders, or clicking directly on elements. When connected to a team’s design system, it applies the brand automatically โ€” and exports to PDF, PPTX, Canva, or a shareable URL. It’s powered by Opus 4.7 and is in research preview for Pro, Max, Team and Enterprise users. Figma closed down 7.3% the day of the announcement. For a comms team that generates a lot of one-off visuals, this is worth a serious look.

The “Mythos” moment: Anthropic keeps its most capable model off the market

The story dominating AI conversation this week is Anthropic’s decision not to publicly release Claude Mythos, which it describes as its most powerful model ever. Roughly fifty partner organisations have been given gated access under a program called Project Glasswing. The stated reason: Mythos’s cybersecurity offensive capabilities are too dangerous for general release. Scientific American has a plain-English explainer; Gary Marcus argues the threat was oversold. Either way, it has re-opened the regulation debate โ€” precisely at a moment when the EU is finalising trilogue on the AI Act’s high-risk provisions and China has just issued its new Trial Guideline on the Ethics Review and Service of AI.

MacRumors / Perplexity

Perplexity Personal Computer for Mac is now rolling out โ€” turn a Mac mini into an always-on agent

Perplexity Max subscribers can now install Personal Computer, an agent that lives on your Mac (macOS 14 Sonoma or later), reads your files, and actually does things โ€” tidying your Downloads folder, working through a to-do list, comparing local documents against what’s on the web. Perplexity is explicitly recommending it on a Mac mini left running 24/7. Under the hood it can spin up teams of sub-agents across 20+ frontier models. Every action is auditable, reversible, and sandboxed, with a kill switch. Perplexity’s ARR has jumped to ~$450M, a 50% month-over-month surge driven by this agentic pivot.

Compute wars: Broadcom expands chip deal with Anthropic to 3.5 gigawatts

Broadcom has struck an expanded deal giving Anthropic access to roughly 3.5 gigawatts of compute capacity running on Google’s TPUs. Separately, OpenAI, Anthropic and Google are coordinating on measures to slow Chinese rivals’ ability to extract answers from US frontier models and train on them โ€” a significant shift from the “rivals won’t cooperate” narrative. Anthropic’s annualised revenue is approaching $19B; OpenAI has crossed $25B and is signalling possible IPO groundwork.

AI News Roundup

Models & Platforms
Meta Muse Spark โ€” Meta’s first proprietary frontier model since hiring Alexandr Wang. Unlike Llama 4, Muse Spark is a closed, hosted model available only through meta.ai.
Claude Opus 4.7 โ€” Released April 16, now the default flagship. Reddit has already nicknamed it “Gaslightus 4.7” after early reports of overconfident wrong answers; vision accuracy reportedly jumped from 54% to 98.5% on one benchmark.
Google Gemma 4 & Gemini 3.1 โ€” Gemma 4 is now the #3 open-weight model on Arena; Gemini 3.1 Ultra is tied with GPT-5.4 Pro at 57 on the Artificial Analysis Intelligence Index.
“AI Zuckerberg” โ€” Meta is reportedly training a photorealistic 3D Mark Zuckerberg avatar to attend internal meetings on his behalf. File under: what CEOs will actually do when presented with this technology.
Enterprise & Deals
Hyatt ร— OpenAI โ€” Enterprise-wide ChatGPT rollout announced today (see Top Stories).
Towngas ร— Tencent โ€” Strategic partnership signed today in Hong Kong to drive “Energy + Tech” digital transformation, with AI innovation as a core pillar. (See Tencent Mentions.)

Policy & Regulation
China’s new ethics guideline โ€” Beijing has issued a joint ten-department Trial Guideline on the Ethics Review and Service of AI. It mandates internal ethics committees and layers expert-level review on top of algorithm filing โ€” the strictest regime globally for public-opinion-facing systems.
EU AI Act โ€” The Digital Omnibus on AI is in trilogue, with a political agreement targeted for April 28. The high-risk systems wave will be formally delayed; industry is treating this as the most important regulatory date of Q2.
US Executive Order 14365 โ€” The Trump administration’s December order is still working through implementation; the DOJ’s new AI Litigation Task Force has begun challenging state AI laws it considers “onerous.”
Research & Benchmarks
Tencent HY-World 2.0 โ€” Tencent open-sourced a multimodal 3D world model now ranked #1 on Stanford’s WorldScore benchmark for open-source world models. Released the same day as an Alibaba equivalent.
Stanford AI Index 2026 โ€” Now out, with the most thorough charts of the current landscape. MIT Technology Review has a good summary.
Reuters Institute on AI & news โ€” Fresh report on how newsrooms are using AI for verification, audio cleanup, image editing, and turning documents into structured data. The Guardian’s use of AI to generate navigation titles is singled out.
Oddities & Signals
Honor’s “Flash” robot beats the human world record โ€” Finished the Beijing E-Town Half Marathon in 50:26 using dry-ice cooling and F1-style battery pit stops. Rival robots fell over at the starting line.
OpenAI pre-IPO exits โ€” Bill Peebles, Kevin Weil and Srinivas Narayanan have all announced departures ahead of a possible listing, per The Neuron.

AI Workflows & Tool Watch

Claude Code “Routines” โ€” cron for AI agents

Anthropic has shipped Claude Code Routines: scheduled cloud automation without a DevOps stack. You can trigger a Claude Code agent on a schedule, from a GitHub event, or via an API call โ€” using the same terminal workflow you already use locally. Useful for scheduled drafts, newsletter digests, or monitoring tasks that previously required n8n or a Zapier Pro plan.

MCP tool results can now pass 500K characters (up from ~25K)

Claude Code’s April point releases (v2.1.89โ€“v2.1.92) added an opt-in `anthropic/maxResultSizeChars` annotation that lets MCP servers return results up to 500,000 characters without truncation โ€” a big deal if you want to hand Claude an entire database schema, a long transcript, or a full Notion page. Translation for non-engineers: Claude can now actually read the big documents you hand it from other tools, end-to-end, instead of being fed a chopped-up version.

Directly relevant: Claude Code, Cowork mode, Notion, Slack, Obsidian MCP integrations

Claude + Obsidian via MCP โ€” your vault becomes a live workspace

The Obsidian community’s most-discussed workflow this month is connecting Claude Code to your vault through MCP. Claude can then read, search and modify notes autonomously. The “claude-obsidian” knowledge engine goes further: when you ingest a new source, it creates entity and concept pages, cross-references every existing note, flags contradictions and updates the index. Useful for journalists and researchers drowning in clippings.

Directly relevant: Obsidian, Claude Code, DEVONthink (similar workflow under discussion)

Perplexity Personal Computer on a spare Mac mini

If you have an old Mac mini sitting unused, Perplexity is explicitly positioning Personal Computer as an always-on assistant that can run on one. It organises your downloads, works through to-do lists, and compares local files against information on the web โ€” all through teams of agents across 20+ frontier models. Every action is reversible and auditable, with a kill switch.

Directly relevant: Mac mini hardware, Eagle (image management), Apple Notes, personal file organisation

Hermes Agent โ€” a persistent AI assistant that lives on your server

Featured this week by One More Thing in AI. Unlike a chat window that forgets you, Hermes is installed once on a server (or a Mac mini) and stays running. It integrates with Slack, Discord and Signal โ€” so you can ping it from anywhere โ€” and has sophisticated scheduling and delegation logic. Five sandboxing backends mean you can restrict what it can actually do on your machine. A good candidate for a “team concierge” bot for global-comms coordination across time zones.

Directly relevant: Slack, Signal, iMessage workflows, cross-timezone team coordination

“ui-ux-pro-max” โ€” a fix for Claude Design’s sameness problem

If you try Claude Design and it produces the default teal-and-serif aesthetic everyone on Reddit is complaining about, an open-source Claude skill called ui-ux-pro-max ships 50+ styles, 161 colour palettes and 99 UX guidelines. Install it as a skill and Claude builds a proper design system first, then generates your screens. Useful for producing visuals that actually feel on-brand.

Directly relevant: Claude Design, Claude Code skills marketplace, internal brand assets

n8n is pulling ahead of Zapier for agent workflows

Zapier has shipped Agents + Copilot, but n8n now has 70+ AI and LangChain-native nodes โ€” more than Zapier and Make combined โ€” and a mature LangChain integration that lets you build multi-step agents with memory and RAG directly in the visual builder. If you’ve been on the fence about self-hosting, this is the month to revisit it.

Directly relevant: n8n, Zapier, Make (Integromat), Keyboard Maestro chaining

Keyboard Maestro + MacWhisper + GPT-4o-mini for voice-to-clean-text

A popular Keyboard Maestro Discourse macro this week: dictate into MacWhisper, pipe the raw transcript into GPT-4o-mini through Apple Shortcuts, and have Keyboard Maestro paste the cleaned-up version wherever your cursor is. For anyone drafting messages on the move, this is the best currently-shipping version of “speak, edit, paste” on macOS.

Directly relevant: Keyboard Maestro, MacWhisper, Apple Shortcuts, Drafts

Claude Code plugins marketplace crossed 2,849 skills

Third-party marketplaces like tonsofskills.com (423 plugins, 2,849 skills, 177 agents) and SkillsMP (800,000+ skills across Claude Code, Codex, Gemini CLI, Cursor) have become the easiest way to discover pre-built AI workflows. Of interest this week: executive-assistant-skills and token-optimizer.

Directly relevant: Claude Code, Cowork mode, internal skill development

Watch for the launch communication around both.

AI compute prices rise across China โ€” Tencent joins Alibaba, Baidu, Zhipu

TrendForce reports Tencent has joined Alibaba, Baidu and Zhipu in raising AI compute prices โ€” a signal that the demand/supply pressures showing up in Anthropic’s uptime numbers are also being felt in China. Worth keeping on the radar for any market-commentary questions.

Tencent Video CEO: first blockbuster AI-generated drama expected H2 2026

Top executives at Tencent Video (and iQiyi) have told Yicai that the first premium, long-form AI-generated drama in Chinese will debut in the second half of 2026. One production team reportedly has a title ready. This is a story worth tracking for its narrative value in any global AI-in-media conversation.
