Anthropic Splits the Meter, Google Kills the Add-On

Anthropic Ships the Brain, Perplexity Ships the Body

Anthropic released Claude Fable 5 to the public on Tuesday — the first Mythos-class frontier model with general availability. One million token context, one hundred and twenty-eight thousand max output, reasoning always on, and the long-horizon memory management that makes multi-day work possible. Available day-one on Amazon Bedrock, Snowflake Cortex AI, and Databricks Unity AI Gateway. Free inside Claude Pro and Max through June 22, then per-use pricing. Same week, Perplexity raised $200M for Comet on a $20B valuation — a bet that the browser, not the chat box, is where agents do real work. What you'll learn: * What Fable 5's long-horizon memory management actually unlocks for the two-week analyst workflows that matter to your business — and why the June 22 free-tier deadline is on the clock. * The "invisible interventions" governance signal most outlets missed — what Anthropic is doing on frontier-model-development prompts that doesn't show up as a refusal, and why that matters for your acceptable-use policy. * The Perplexity Comet bet on browsers as the agent surface — and the funnel question your CMO needs to answer before agentic visitors break your conversion path. * Why "Anthropic ships the brain, Perplexity ships the body" is the pattern of the week — and what it means for moving AI from something you query to something that operates. Three desk actions: 1. Test Fable 5 on your hardest two-week workflow before June 22 — while it's free in Pro and Max. 2. Ask your CMO or head of digital: what changes about our conversion funnel if the visitor is an agent and not a human? 3. Have General Counsel review your acceptable-use policy in light of Anthropic's invisible interventions on frontier-development prompts.

Today's Fable 5 release is the model upgrade that forces you to confront that new meter — Fable runs at roughly twice the price of Opus 4.8 for output tokens, and long-horizon tasks burn an order of magnitude more.

Anthropic Splits the Meter, Google Kills the Add-On

Two vendor moves landed this week that change how AI shows up on your statement and what tools your team can open. Anthropic split Claude Code billing into interactive seats plus a separately metered Agent SDK credit pool — same playbook Microsoft just ran with GitHub Copilot. Google rewires NotebookLM into a real agent and quietly kills the Workspace AI Ultra Access add-on with a July 7 transition deadline. Plus a tips-and-tricks segment on how a model-routing swap and a Perplexity Spaces versus Claude Projects test changed where I spend my AI budget. What you'll learn: * How Anthropic's split between Claude Code interactive seats and the metered Agent SDK credit pool changes your monthly bill — and what to do before the auto-pay hits. * What the NotebookLM upgrade actually unlocks for board prep and diligence work — and which Workspace seats lose Antigravity, Gemini CLI, and Gemini Code Assist on July 7. * The model-routing hack that cut my high-reasoning Perplexity bill by about 70 percent — and the Perplexity Spaces versus Claude Projects test that changed my mind about where context lives. * The "back door" pricing model that gets a small team onto enterprise-grade security at roughly 3,000 dollars a year.

In last week's episode titled "The Bill Has Arrived," we covered Microsoft's GitHub Copilot pricing shift to usage-based AI Credits. Hosted by Stephen Forte.

Apple Blinks

Three institutions reached the same conclusion this weekend — nobody wins at AI alone. Apple opens WWDC today with Tim Cook's final keynote. The headline: a completely rebuilt Siri running on a custom 1.2-trillion-parameter Gemini model licensed from Google at one billion dollars per year. Apple — four hundred billion dollars in cash, forty years of disciplined engineering — concluded it cannot build frontier models competitively. The contract contains a clause that should rewrite every enterprise AI negotiation: Google is barred from using Apple Siri queries to train future models. That is now your template. Anthropic published research showing Claude agents run end-to-end projects autonomously at a seventy-six percent success rate, up fifty points in six months. Engineers merging eight times more code per day. The claim: a one-hundred-person company can do the work of a one-thousand-person one. Trump signals the government should own stakes in frontier AI labs. DeepSeek is raising seven point four billion dollars. The capital cold war is accelerating. Two desk actions: add data-isolation language to your next AI vendor renewal, and ask whether your governance infrastructure can support a knowledge worker managing five agents.

The Reckoning

Two new principals just walked into every room where AI decisions are being made — the federal government and public markets. President Trump signed an executive order on June 2 creating a framework for government pre-release access to frontier AI models. Anthropic picked Morgan Stanley and Goldman Sachs to lead its IPO. OpenAI is targeting a fall IPO. SpaceX filed for the largest IPO in history. Three of your most critical AI vendors are heading to public markets simultaneously. This episode covers what both developments mean for enterprise buyers — the voluntary framework that may not be truly voluntary, and what publicly traded AI vendors mean for your contracts, roadmap commitments, and vendor risk model. Two desk actions: review your Anthropic/OpenAI contracts before the IPO window, and read Sections 2 and 3 of the executive order if you are in financial services, healthcare, critical infrastructure, or defense.

The Agents Are Already Inside

You did not approve these agents. There was no vendor evaluation, no procurement process, no board sign-off. But they are running in your environment today. This episode covers three agents that arrived without the normal enterprise procurement process: Microsoft Scout — the always-on ambient AI agent now live inside Microsoft 365; Accenture's strategic investment in AlphaSense — the agentic market intelligence platform used by ninety percent of the S&P 100; and Anthropic's Mythos cybersecurity AI, now running in over one hundred fifty organizations across fifteen countries including critical infrastructure. The question is not whether to adopt AI agents. That decision has already been made for you. The question is whether you know what they are authorized to do. Three desk actions: ask your CTO what Scout is authorized to do in your environment; find out if your top competitors are using AlphaSense; and if you are in critical infrastructure, ask your security team about Glasswing access.
