🚀 Claude Sonnet 4 Just Raised the Bar for AI Coding
So, I’ve been playing around with Anthropic’s new models — Claude Opus and Sonnet 4 — and wow… I think we’ve got something special here.
After spending a few hours coding with Sonnet 4, I’m honestly blown away. I’ve been using Claude Sonnet 3.5 for about a year, and while it’s been solid, this new version feels like a major upgrade.
And if you tried Sonnet 3.7 and felt let down (like I did), you’ll be happy to hear: they actually fixed the stuff that didn’t work.
What’s New (and Actually Better)
Sonnet 4 somehow blends the best parts of 3.5 and 3.7. It’s confident and proactive like 3.7, but the code it writes actually runs, like 3.5. No more test-cheating, no more over-engineering.
To test it out, I gave it a few real-world challenges:
Fixed a super annoying layout bug in a sidebar that other models just couldn’t handle.
Rebuilt a full stack QR code contact app that originally took me 2.5 hours. This time? Just over an hour.
It Thinks Before It Types
Here’s what really stood out: Sonnet 4 doesn’t just rush into code changes. It reads — like, really reads — across multiple files, then makes one precise fix.
It even handled a tricky Tailwind v4 config issue that usually trips up AI. I didn’t even hint at what to do, and it figured it out.
The Little Things That Matter
Sonnet 4 is packed with thoughtful upgrades that quietly make a big difference:
Smart UX choices: It generated QR codes as actual contact cards — a tiny detail that made the app way more useful.
Self-updating README: It documents projects as it works, which keeps future tasks (and conversations) much smoother.
Hybrid Reasoning: With its new “extended thinking” mode, Sonnet 4 can choose between lightning-fast answers and deeper, more deliberate reasoning.
Improved Accuracy: It’s 65% less likely to rely on shortcuts or logic loopholes compared to Sonnet 3.7 — and you can feel the difference.
Enhanced Memory: It can now pull key info from your local files and remember it across long-term tasks.
Smarter Tool Use: It even knows when to reach for a tool like web search to complement its internal reasoning — think of it like switching from thinking to Googling, and back again.
Widely Available: Whether you’re a free or paid user, you can use Sonnet 4 via the Claude web app, or through the Anthropic API, Amazon Bedrock, and Google Cloud’s Vertex AI.
Bottom line: I’m genuinely impressed. This might be the first time I’m ready to move on from Sonnet 3.5 for good.
If you’ve tried it, I’d love to hear what you think. And if not, I definitely recommend giving Sonnet 4 a spin — especially if you’re into building apps with AI.

AI TUTORIAL
🎥 Getting Started with Flow: A Creator’s Guide to AI-Powered Video
If you've ever wanted to create cinematic-quality videos without spending hours editing or animating—you're going to love this.
Let me introduce you to Flow, a generative video tool designed with filmmakers to help you turn your ideas into powerful video clips. It uses the best from Google DeepMind—Veo, Imagen, and Gemini—to help you build stunning scenes with just a few clicks (and some well-crafted prompts).
Here’s a quick walkthrough to get you up to speed:
📁 Start with Your Projects
Everything lives in your Project View. It’s super clean and easy to navigate. You can scroll through your work, open existing projects, or start fresh.
✍️ Write a Prompt, Get a Video
By default, you’re in Text to Video mode. Just type what you want to see, and Flow will generate it for you. Want more control? You’ve got options.
🎞️ Try Frames to Video
Switch to Frames to Video to use specific images as starting points (or end frames). You can:
Pull from your ingredients drawer (a collection of images you've used before)
Upload new frames or generate fresh ones
Add camera moves without writing them out—just click and preview
🧩 Mix & Match with Ingredients to Video
This mode lets you combine characters, locations, and objects in one scene. Add a prompt, and Flow figures out how they interact. It’s a great way to keep visual elements consistent across clips.
🎬 Build Scenes in Scenebuilder
Once you’ve got some clips, head to the Scenebuilder to bring it all together:
Click “Add to Scene” to move clips into the timeline
Use Jump To (powered by Gemini) to generate the next logical clip
Trim, extend, rearrange—whatever your story needs
Save frames for later use
When you're happy, just click download 🎉
⚠️ Heads-up: Access Requirements & Pricing
Flow is currently available exclusively to subscribers of Google's AI Pro and AI Ultra plans.
Google AI Pro: $19.99/month, includes access to Flow (powered by Veo 2), Gemini in Chrome, and 2 TB of storage.
Google AI Ultra: $249.99/month, offers the highest usage limits, early access to Veo 3 with native audio generation, Project Mariner, YouTube Premium, and 30 TB of storage.
You can start using Flow by visiting the Google Labs Flow page.
We’re genuinely excited about what Flow can do—and we can’t wait to see what you create with it.
Whether you’re storyboarding, experimenting, or working on a full short film, this tool puts some serious power in your hands.
