Dr. Violet Howard shows how to build AI automations with Claude Sonnet 4.5 and n8n. Sonnet 4.5, released September 29, 2025, scores 77-82% on coding benchmarks and outperforms other Claude models in finance, medicine, and law. A live workflow demonstrates the agent researching with Perplexity, retrieving contacts, and sending an email to Michael Scott about AI voice agents.

Here's how you can build anything with Claude Sonnet 4.5 and AnyNN AI agents. Of course, we're not just going to be talking about it. I'm going to be showing you guys some stuff too. So we'll hop into AnyNN and we'll actually experiment with a few things with Sonnet 4.5 in AnyNN. Sonnet 4.5 was released on September 29th, 2025. And yeah, I know it feels like a new foundational model is being dropped every single day. And if you've heard of Anthropic, you've heard of Claude, you've heard of Opus. They're all basically baked into Anthropic's Claude model family. They're all basically for different purposes. Haiku's faster, more affordable. Sonnet Sonnet's a good balance, and then Opus is like a max power reasoning model. And as far as the cost, you can see the breakdown right here. Sonnet 4.5 is the exact same cost as Sonnet 4. So of course I wanted to show you guys some benchmarks. So let's look at some of these tests. This first one is the SWE Bench Verified, which is kind of like a coding or software engineering exam. Sonnet 4.5 scored an industry-leading 77 to 82% on this exam. Now this one I thought was pretty interesting. We've got finance, medicine, law, and STEM. And in orange up top, we have Sonnet 4.5, which is outperforming pretty much all of the other Claude family models in these categories. So it gives more accurate and expert-level advice on these topics, which is gonna be really important when you're using AI agents. So I'm telling the agent to do research on voice agents and then send it to Michael Scott. And you can see what's happening here is it's using Perplexity. It's also calling the contact agent. And now we'll see if it's able to pass that information into the email agent and send that email for us. So far so good. You can see it was able to call the email agent as well. Okay, so you can see it actually finished up and it said that it did all of that stuff for us. So let's go take a look at the email. All right. So I was able to send this to the correct email for Michael Scott. We have AI voice agents are intelligent software systems that understand, interpret, and respond to human speech in real time. How they work. We have NLP, we have TTS, we have current applications, benefits, and latest developments, and then a sign-off from Nate.
