I've used every major AI model. ChatGPT, Gemini, Copilot, Llama, Mistral — all of them. I'm not loyal to brands. I'm loyal to results.
And Claude has been quietly winning for months.
Yesterday, Anthropic released Claude Opus 4.6 — their most powerful model yet. I've been using it since it dropped, and I need to tell you what's actually different, because the headlines don't capture what matters for people who use AI to run their work, not just ask it trivia questions.
What Actually Changed
Let me skip the benchmarks and talk about what you'll feel.
The context window went from 200K to 1 million tokens. That's roughly 750,000 words — about 3,000 pages of text — in a single conversation. To put that in perspective, you could paste every client contract, every meeting transcript, every project document you have into one conversation and Claude would hold all of it in working memory at once.
I run my entire consulting business through Claude Projects. Client discovery calls, proposals, scopes of work, pipeline tracking, content strategy — all of it lives in Claude. With 200K tokens, I'd occasionally hit the ceiling on complex client work. With 1 million? I won't come close (probably, lol).
It thinks deeper on hard problems without being told to. Anthropic calls this "adaptive thinking." In practice, it means when I ask Claude to analyze a client's operations and identify where they're losing money, it doesn't just skim the surface anymore. It digs. It considers edge cases. It catches things I'd miss on a first pass. On straightforward tasks, it moves fast. On complex strategy work, it slows down and reasons more carefully — automatically.
It stays productive over longer sessions. This is the one nobody's talking about, and it matters enormously for how I work. Previous models would start to lose coherence in long conversations — the dreaded "context rot" where quality degrades the longer you go. Opus 4.6 scored 76% on a long-context retrieval test where Sonnet 4.5 scored 18.5%. That's not incremental improvement. That's a different league.
It creates production-ready documents, spreadsheets, and presentations. Claude can now generate polished slide decks that match your brand templates, build complex spreadsheets, and produce documents that actually look professional on the first attempt. For anyone who's spent hours reformatting AI output, this is significant.
Why This Matters If You're Not a Developer
Most of the coverage of Opus 4.6 focuses on coding benchmarks and developer tools. That's important — Opus 4.6 leads every major coding evaluation — but it misses the bigger story.
The bigger story is that Claude is becoming an operating system for knowledge work.
Here's what I mean. Claude isn't just a chatbot anymore. It's a platform with interconnected features that, when you actually learn to use them together, fundamentally change how you work:
Projects give you persistent workspaces. Every client gets their own Project with their documents, context, and conversation history. When I open my Skin Equity Project, Claude already knows their business, their tech stack, their goals. I don't re-explain anything.
Memory means Claude remembers you across every conversation. My communication preferences, my pricing structure, my business context — it's all there. I don't start from zero.
Skills are custom tools you build once and reuse forever. I built a proposal generator, a sales call analyzer, a SOW creator. They run inside Claude as reusable capabilities.
Cowork is where it gets wild. Claude can now multitask autonomously — you give it a set of tasks and it works through them independently, using all of the above capabilities. With Opus 4.6's improved planning and sustained focus, this actually works reliably now.
None of this is theoretical for me. This is how I operate daily.
The Real Competitive Advantage
Here's what I keep telling people: the gap between "I use AI" and "AI runs my operations" is enormous. Most professionals are still copy-pasting into ChatGPT and asking one-off questions. They're using AI like a search engine with better grammar.
That's leaving massive value on the table.
The professionals who figure out how to use Claude as an actual coworker — with persistent context, custom tools, and systematic workflows — will operate at a fundamentally different level than everyone else. Opus 4.6 makes that gap wider.
I spent 7 years at Google watching this pattern play out with every new technology platform. The people who invested time learning the system — not just the surface features — compounded their advantage over years. Everyone else stayed in tutorial mode forever.
What I'm Building
I've been using Claude to run my AI consulting business since I left Google in 2025 (and honestly, long before, on my own creative projects). Every week I discover new workflows, new capabilities, new ways to leverage the platform that save me hours and produce better output.
People keep asking me how I actually do this. Not the theory — the actual system.
So I'm building a course that shows you exactly how. Not "here's what AI can do" — you've seen enough of those. This is "here's my screen, here's my setup, here's how I use Claude Projects, Memory, Skills, and now the 1M context window to run strategy, client delivery, content, and operations."
It's called Claude for Everyone, and it's launching next week.
If you want to stop using AI like a fancy search engine and start using it like the most capable coworker you've ever had, follow me here or grab the link when it drops.
The Bottom Line
Opus 4.6 is not just a model upgrade. It's a capability upgrade for anyone willing to learn the system.
A million-token context window means your AI coworker can hold your entire business in working memory. Adaptive thinking means it brings more intelligence to the problems that actually need it. Sustained focus over long sessions means you can work with it for hours without degradation.
The future of work isn't AI-assisted. It's AI-operated.
And the people who learn that now will have an unfair advantage for years.
