Anthropic brings Claude Fable 5 to the public — with guardrails doing much of the work

Anthropic has announced Claude Fable 5 as a public-facing version of its Mythos-class model, paired with a safety design that routes some higher-risk requests elsewhere. The release matters not just because of the model claims, but because it shows where frontier AI deployment is heading: broader access, narrower permissions, and far more explicit controls.

Nicki Borell, a living memory

The news I got over the weekend struck like lightning: Nicki has died. All of us who were close to him expected it, but secretly hoped that something, somewhere in the universe would shift just a little and turn everything into a bad dream with a happy ending. But things don't work that way.

Project Mythos: When AI Started Finding the Bugs Nobody Else Could

In April 2026, Mozilla shipped fixes for 423 security bugs in Firefox. The month before, it was 76. The month before that, 61. Across all of 2025, the average sat between 17 and 31 a month. So something happened — and Mozilla isn't being coy about it. The "something" was a restricted-access Anthropic model called Claude Mythos Preview, paired with an agentic harness Mozilla's engineers built to put it to work.

OpenAI's Realtime reset and what it means for the rest of the stack

OpenAI just put GPT-5-class reasoning inside the audio loop, took the Realtime API to GA, and priced translation at a third of a cent per minute. The voice agent stack everyone built last year suddenly looks expensive.

ShareGate: Microsoft 365 price increases and a new license - What you need to know

Microsoft is making some major changes to Microsoft 365 in 2026. Two things IT leaders and admins should know:

  • Microsoft 365 pricing will increase for seven SKUs: Microsoft 365 Business Basic, Microsoft 365 Business Standard, Office 365 E3, Microsoft 365 E3, Microsoft 365 E5, Microsoft 365 F1, and Microsoft 365 F3.
  • Microsoft will launch its premium Microsoft 365 E7 suite for companies ready to scale AI.

For IT teams, this raises some important questions.

How much will these changes increase your Microsoft 365 costs? Do your current license assignments reflect how employees actually use Microsoft 365? Where might there be opportunities to optimize your Microsoft 365 footprint before costs increase?

Let's dive in.

Veeam: The Future of Microsoft 365 Data Protection - Why SaaS Backup and Data Visibility Matter More Than Ever

Microsoft 365 has become the backbone of modern collaboration. From email and documents to Teams chats and identity services, it powers how organizations work every day. But while Microsoft delivers a resilient platform, one critical fact remains: data protection is a shared responsibility — and protecting your Microsoft 365 data ultimately lies with you.

glueckkanja AG: The Holy Trinity: What AI Actually Needs to Get to Work

A manufacturing company wants to know which of its 14,000 SKUs actually turn a profit. The answer sits in three systems that have never exchanged a single data point. Until recently, getting it required three departments, two weeks and a good deal of goodwill. Since early 2026, an AI can answer that question in minutes: search the data, draw connections, produce a recommendation. Provided, that is, it has access.

The models are ready. They act, execute tasks across multiple steps and system boundaries, prepare decisions, trigger workflows. Many companies have already had their first taste of this through Copilot, but Copilot knows the M365 universe: emails, documents, calendars. To point AI at the data that actually runs the business, at ERP, CRM, IoT and production systems, you need a different foundation.

That foundation has three parts. We built each of them as a managed service, each goes live in three to four weeks, and together they form the platform on which AI can do real work.

delaware: Why you can't AI your way out of unstructured onboarding

There’s a moment most managers know too well: a talented new colleague joins, six weeks pass, and they’re still operating at half speed. So, you schedule yet another catch up, explain the same context again, and quietly wonder: “Is this a people problem?”

It isn’t. It’s an environment problem, or two, actually.

Infobip: AI agents are redefining CX - Infobip is here to help you lead the shift

The way enterprises engage customers is undergoing a fundamental shift. AI agents, autonomous goal-driven systems capable of reasoning, adapting, and acting, are no longer experimental. They are being deployed across customer service, sales, and support functions, redefining what is possible in enterprise customer experience (CX).

But with that opportunity comes complexity. Managing a growing number of AI agents, ensuring they operate within governance frameworks, integrating them across channels and platforms, and scaling them with consistency, these are challenges that many enterprises are only beginning to navigate.

At Infobip, we believe the answer lies in a dedicated orchestration layer: one that gives enterprises the control, flexibility, and scalability to move beyond AI pilots and into real, measurable impact.

That layer is AgentOS.

Xylos / OASE: PlayForward - Where Learning Meets Gaming (and Actually Sticks)

Let’s be honest: keeping up with Microsoft 365 and AI can feel like a full-time job. New features appear overnight, AI evolves at lightning speed, and users are expected to “just keep up.” Training often ends up being postponed, skipped, or forgotten.

That’s exactly why we created PlayForward and why we’re excited to showcase it at the European Collaboration Summit.
