NEW Claude Sonnet 5 Changes Everything!

New Claude Sonnet 5 is insane, and today I'm going to show you exactly why this changes everything for business owners using AI. This is not a small update. Anthropic just dropped Claude Sonnet 5 on June 30th, 2026, and I'm going to show you what it can actually do, how it's already being used by real businesses, and how you can use it to grow your business without doing everything yourself. Stay with me because what I'm about to show you in the middle of this video is going to blow your mind.

So here's the big thing. Claude Sonnet 5 is Anthropic's most agentic model ever. That word, agentic, is the key word. It means the AI doesn't just answer your questions anymore.

It makes a plan. It takes action. It uses tools like browsers and computer terminals. It checks its own work, and it keeps going until the job is done.

Anthropic said it themselves, this model can run autonomously at a level that just a few months ago required their biggest and most expensive models. Let that sit for a second. Six months ago, you needed the most powerful AI in the world to do what Sonnet 5 now does on the free and pro plans. That's the shift happening right now.

Hey, if we haven't met already, I'm the digital avatar of Julian Goldie, CEO of SEO agency, Goldie Agency. Whilst he's helping clients get more leads and customers, I'm here to help you get the latest AI updates. And Julian Goldie reads every comment, so make sure you comment below. And if you're using AI to grow your business or run your SEO, this matters a lot because the old way of using AI was this.

You ask a question, you get an answer, you copy paste it somewhere, and you do the rest yourself. The new way is totally different. You give it an objective. It figures out the steps.

It does the steps. It checks the results. It fixes mistakes. You come back and the work is done.

Here's a real example of that happening. Zapier gave Claude Sonnet 5 a two-part job. First, update Salesforce account tiers. Second, send a launch announcement to their enterprise contacts.

That's two separate tasks across two different systems. Claude did both end to end without stopping, without asking for help halfway through. Zapier said that workflow used to stall halfway. Now it finishes.

So what does that mean for you? Think about the repetitive stuff you do every single week for your business or for your SEO. Checking rankings, researching competitors, updating content, writing outreach emails, building reports. What if you could hand that to an AI that actually sees it through to the end?

That's what this model is starting to make possible and the benchmark numbers back it up. On agentic coding, Sonnet 5 scores 63.2%. The old Sonnet 4.6 scored 58.1% and the biggest, most expensive Opus 4.8 scored 69.2%. Sonnet 5 is sitting right below the flagship model but on a much lower price tier.

On knowledge work, the stuff that matters most for business owners, Sonnet 5 actually slightly outperforms Opus 4.8. The mid-tier model is beating the top tier model at business tasks and it's now the default model on the free and pro plans, which means if you open Claude right now, you're already using it. Now here's something that not many people are talking about. Sonnet 5 also checks its own output without being told to.

Early testers described how it finishes complex tasks where older Sonnet models would stop short and it double checks the work on its own without you asking it to. Riyad Dahimane, director of product at Clickhouse said Sonnet 5 reasons in tighter steps and gets users to answers noticeably faster. Mauricio Wolfovich from the legal AI company Eve said Sonnet 5 is on the Pareto frontier for their tasks with the biggest gains in research and analysis. These are people building real tools for real businesses and they're all saying the same thing.

The follow-through is better. It gets further before it needs help and it does more with less back and forth.

Okay, back to it. Now I want to show you something really practical. If you're running a business and you want to grow it using AI automation, here's exactly how you'd use Sonnet 5. Let's say you want to grow the AI profit boardroom community.

You could give Sonnet 5 a prompt like this. Act as head of growth for the AI profit boardroom. Research our main competitors. Identify the top 10 content gaps where we can get more traffic and leads.

Write 30 YouTube video ideas targeting business owners who want to learn AI automation. Then draft a five email welcome sequence for new members. And Sonnet 5 doesn't just spit out a list and stop. It browses, it researches, it plans, it writes, it checks, the emails are consistent, it keeps going.

That used to take a team, now it's one prompt or here's another one. You are the SEO strategist for the AI profit boardroom. Research our top 20 competitor websites. Find the keywords they rank for that we don't.

Create a 30-day content plan with article topics, target keywords, and SEO briefs for each one. That's a week of SEO work handed off to an AI agent that can actually browse the web and complete the task. And for people who want to take this even further, the context window on Sonnet 5 supports up to 1 million tokens. That means you can feed it your entire community history, all your customer conversations, your SOPs, your email list data, your landing pages, everything.

And then say, how do we get more members? It processes all of it and gives you answers based on everything, not just a slice of it. Now, here's where it gets interesting for the people watching this who are serious about growing their business online. The context window isn't the only thing that changed.

Sonnet 5 is also significantly better at using computers directly. Okay, so let's zoom out. We've gone from AI that answers questions to AI that follows instructions to AI that plans and executes multi-step tasks on its own. That progression has happened in just a few years.

And now the most capable agentic AI is sitting on the free tier of Claude. The businesses that figure out how to use this well, not just to answer questions, but to genuinely run workflows, are going to move a lot faster than the ones still doing everything manually. There's a ceiling on what you can get done when every task needs you to be in the room. Agents like Sonnet 5 start to remove that ceiling and the full Claude model stack is moving up at once.

Sonnet 5 at the mid-tier, Opus 4.8 above it, and Fable 5 sitting at the top for the hardest tasks. The question isn't whether AI agents are going to be part of business operations. They already are. The question is whether you're going to be the person who knows how to use them.

So here's where to go from here. If you're completely new to SEO and want to build a solid foundation alongside the AI tools, how content strategy works, how to approach link building, what a good keyword looks like, we've got a free SEO course in the description with over 260 lessons.
