@tymofii Yes, thanks. Just a little hesitant to go for the API quite yet..

How do you find the latest Claude model??

I just had a great 5h session with Claude Fable 5. Although it is quite hungry for tokens, it also gets a lot of stuff done. I basically used 50% of my weekly limit in 3 5h sessions.

Example:
Directory submissions used to be tough muscle work - Fable just ran all of them together.. 🤯

Have to MAX out the usage until the 22nd..

Any tips on how to get the most of the fun before it ends?

More capability without attribution is just more noise.

The teams that win aren't the fastest adopters.

They're the ones who know which AI touchpoint actually influenced the deal.

3 major AI launches this week.

Anthropic filed for IPO at $65 billion. OpenAI dropped GPT-5.5 Instant. Google shipped Gemini 3.5 Flash.

The intelligence layer of your stack is accelerating faster than anyone predicted.

[Ville Ylläsjärvi @yllasville]

Here's what nobody's talking about:

Most B2B teams can't tell you what any of it is doing for pipeline.

Not because they're not using AI. Because they never built the measurement layer first.

[Ville Ylläsjärvi @yllasville]

The AI arms race has entered a new phase.

The question isn't which model wins — it's which workflow wins first.

Are you building on the right foundation?

Anthropic just hit a $965B valuation — leapfrogging OpenAI as the world's most valuable AI startup overnight.

Here's what it means for builders:

[Ville Ylläsjärvi @yllasville]

Claude Opus 4.8 is setting new benchmarks. OpenAI just unlocked Codex for non-developers — product managers, lawyers, ops teams.

AI is no longer a dev-only game.

[Ville Ylläsjärvi @yllasville]

First touch with Fable.

Had to upgrade. Well done @AnthropicAI

What actually happens when identical content runs on X, LinkedIn, and Threads simultaneously?

Same idea. Same day. Measured against each platform's own baseline — not each other's.

The differential tells you everything the "post everywhere" crowd never bothered to measure.

[Ville Ylläsjärvi @yllasville]

@sflorimm I am building a product that reduces token spend..

Otherwise it is all about planning wisely, keep tasks and workflows focused. Ask the WF orchestrator to use Sonnet in subagents.

[Ville Ylläsjärvi @yllasville]

The signal if you're building on AI:

Competition is collapsing costs across every lab.

The model that was too expensive 6 months ago? Now table stakes.

The moat isn't which LLM you pick — it's the workflow you build around it.

[Ville Ylläsjärvi @yllasville]

Anthropic just became the world's most valuable AI startup.

$965 billion. Leapfrogging OpenAI for the first time.

And that's just one headline from the wildest week in AI this year 👇

[Ville Ylläsjärvi @yllasville]

This week in AI:
→ Anthropic hits $965B valuation (overtakes OpenAI at $852B)
→ Microsoft ships 7 MAI models — first reasoning model trained WITHOUT OpenAI data
→ Google Vids: free AI video (Veo 3.1) + AI music + avatars → direct YouTube publish
→ GPT-5.5 Instant: 52% fewer…

For social media managers: 87% of marketers already use AI in their workflows. But Hatch means your content won't just be seen by humans anymore. The brands who optimize for AI-assisted discovery will own the next era of social. Is your content strategy ready for that?

[Ville Ylläsjärvi @yllasville]

Meta is embedding an AI agent called Hatch inside Instagram. 2 billion users. No separate app needed.

[Ville Ylläsjärvi @yllasville]

Hatch can browse, shop, and interact on users' behalf. It's being trained on simulations of DoorDash, Etsy, and Reddit. Priced at $200/month for premium. This isn't a chatbot — it's a new kind of user in the feed.

[Ville Ylläsjärvi @yllasville]

Most founders will use AI as a better search engine.

A few will use it as a team.

The gap between those two groups just got wider this week:
→ Google launched autonomous agents that run without your input
→ Microsoft's MAI-Code-1 builds full apps from plain text
→ Zoom's ZoomMate ($20/mo) turns meeting chaos into polished docs
→ SoftBank committed €75B to AI infrastructure in France alone

AI isn't becoming more capable.
It's becoming more independent.

The question isn't "how do I use AI better?"

It's "what am I building while AI runs in the background?"

Founders who answer that in the next 90 days will be untouchable.

[Ville Ylläsjärvi @yllasville]

The early adopter gap widens every single week.

The AI landscape just shifted again — and most people missed it 👇

3 flagship models dropped, ChatGPT got its biggest memory upgrade since launch, and a coding AI just hit a $25B valuation.

Here's your 60-second brief:

[Ville Ylläsjärvi @yllasville]

The real signal: Cognition (Devin AI) raised $1B at a $25B valuation.

AI agents that write code, run tasks, and automate entire workflows are no longer experiments.

They're becoming core business infrastructure.
