Everyone’s Talking About DeepSeek and o3-Mini... But Should You Use Them? Instead of following the hype, let’s look at the data.

Here’s what stands out:

šŸš€ DeepSeek-R1 has completely replaced Claude 3.5 Sonnet.
Same SWE-Bench performance, but at a fraction of the price. If you’re still using Claude, you’re paying extra for no real reason.

šŸ’° Claude 3.5 Sonnet is insanely expensive.
At $15 per million output tokens, it only makes sense for very small coding tasks—otherwise, DeepSeek-R1 is just better.

⚔ o3-mini is the best choice for serious AI tasks.
• 200K token context window
• 1,637 tokens per second throughput (fastest on this list)
• Relatively low cost compared to Claude & GPT-4o

For complex AI applications, o3-mini is a no-brainer.

I’m making the switch—o3-mini for everything going forward.

What’s your pick?

Battle of the AI Models: Which One is Best for Agents?

I’m deep in testing O3-Mini, GPT-4o, DeepSeek-R1, and DeepSeek-V3 to figure out which model is truly the best for AI agents.

To find the winner, I’m stress-testing them against the most common tasks agents need to handle:

🧠 Instruction Overload: Can it handle rule-heavy tasks without getting confused or hallucinating?
šŸ› ļø Tool Call Hell: Can it handle 5 consecutive tool calls, feeding results from one into the next without breaking?
šŸ” Needle in a Haystack: Can it retrieve precise information from large datasets while staying contextually aware?

So far, one model is dominating—and I’ll be switching all of my agents over to it going forward.

I’ll share the full results (and the winning model) in my upcoming video—recording tomorrow, dropping Thursday! Stay tuned.

Which model do you think will win? Drop your guesses below! šŸ‘‡

In the middle of stress testing o3-mini and DeepSeek-r1.

o3-mini is winner - it's not even a competition!

I'm testing each model against the most common developer tasks:
1ļøāƒ£ Build a new project from scratch
2ļøāƒ£ Build a new feature in an existing app
3ļøāƒ£ Refactor existing code and generate tests

-

With o3-mini and cursor, I was able to build a ChatGPT replica that allows me to chat with local LLM models in a single shot and everything works like a charm!

On the other hand, DeepSeek-r1 got stuck and only generated a single javascript file. Far from a fully functional website.

Here's the GitHub repo with the prompts so you can replicate the results on your own:

github.com/bhancockio/o3-mini-vs-deepseek-r1

The screenshot below shows the functional app that o3-mini was able to create in a single shot!

I'm still working on the second 2 tasks but right now, there is a clear winner.

I'll keep you posted as I keep testing.

Also, I'll be putting all of this into a YouTube video that will hopefully come out on Monday!

If you have any questions around o3-mini or deepseek-r1, let me know!

I feel like I have a PHD on these models after all the testing I've done over the past 24 hours.

Hey guys! šŸ‘‹ I'm super excited to share something that's going to change how you interact with your CrewAI setups.

We've just launched a game-changing feature called `crewai chat` that lets you have real conversations with your crews!

In my upcoming video (dropping early this week!), I'll show you exactly how I used this feature to create a professional newsletter in just 5 minutes. Yes, you heard that right - FIVE minutes! šŸš€

Here's the magic: I simply chatted with my crew, refining the output until it was perfect. The result? A newsletter that's ready to send to my community.

Check out the actual newsletter my crew generated on Substack in the link below.

Stay tuned for the video release, and in the meantime, let me know what you think of this new feature!

Would you use crewai chat in your workflow?

Cheers,
Brandon Hancock šŸ‘Øā€šŸ’»šŸ„‚

Quick ‪@crewAIInc‬ and LLM Tip:

LLMs are lazy and struggle with word count.

So, if you're creating a Newsletter or Blog Crew where word count matters, give your agent a Word Count Tool (code below šŸ‘‡).

Without a Word Count Tool, LLM's give you 800 words max by default because they can't count.

With a Word Count Tool, the agent sees it's not generating enough content and continually rewrites the post until it hits the perfect word count!

-

I bring this up because I'm working on a new YouTube video for y'all that shows you how you can chat with your crews using the new `crewai chat` feature.

In this video, we're going to chat with our Newsletter Crew and continually provide feedback until the Crew generates the perfect newsletter!

Normally, writing a newsletter could take hours.

When you're chatting with a Newsletter Crew, it takes a couple minutes!

I'm super excited for y'all to see this video when it comes out early next week!

I'm wrapping up recording for the Sora masterclass right now, but I wanted to go ahead and share a GPT I created for you guys to help you make AMAZING Sora prompts.

This GPT will help you level up your prompt game from this:

"A beautiful woman sitting outside at a cafe."

To this:

"A beautiful woman sits gracefully outside a quaint cafe in a bustling city at sunset. She sips her coffee while gazing thoughtfully into the distance, surrounded by warm, golden light. The setting is alive with soft chatter and the clinking of glasses, framed by lush greenery and bistro tables. Style: Romantic and cinematic."

In the comments below, I've a link to the GPT so you can try it yourself!

Hey everyone! šŸ‘‹

Today, I’m super excited to share a sneak peek of my latest video, where I walk you through the ultimate AI tech stack for building MVPs (Minimum Viable Products) lightning fast. If you’ve been trying to get your AI projects off the ground or want to quickly showcase proof-of-concepts to your clients, you’re in for a treat.

šŸš€ Why This Stack?

In the upcoming video, I break down a powerful combination of Claude, V0, and Cursor. These tools, when used together, help you build beautiful and functional Next.js MVPs in record time.

The Stack Breakdown:
- Claude – Acts as the brains of the operation, helping you brainstorm ideas, outline, and strategize. Think of Claude as your project’s foundation.

- V0 – This is your MVP powerhouse. It can crank out Next.js components like a pro and streamline server-side logic to get your app running fast.

- Cursor – Cursor polishes the details, handles data cleanup, and makes those last-minute tweaks that turn a good MVP into a great one.

✨ Real-World Use Case: Real Estate Offer Letter Generator
Let me show you a real-world example. In the video, I walk through how I built a Real Estate Offer Letter Generator in just a couple of hours:

- Input client details and upload documents like conversations and specs.

- Auto-generate offer letters based on uploaded info.

- Tweak values like offer price, export the document, and send to clients with a few clicks.

The coolest part? What usually takes hours was done in minutes using this stack! 😲

šŸ‘·ā€ā™‚ļø Building the Pyramid: From Concept to MVP in No Time
I like to think of it as constructing a pyramid:

- Base Layer: Claude pulls all your ideas and turns them into a concrete plan.

- Middle Layer: V0 builds out the core components, pages, and server-side logic.

- Top Layer: Cursor polishes the details and handles tweaks to ensure everything runs smoothly.

šŸŽÆ Why This Stack Matters for You
If you’re a startup founder, this stack lets you get feedback fast. Instead of spending weeks on a product, you can validate concepts in days. šŸ’”

For AI freelancers, this is your secret weapon to wow clients. Deliver a functioning proof-of-concept in just hours—you’re not just selling ideas, you’re showing what’s possible.

Watch the Sneak Peek šŸŽ¬
In the video, I show exactly how I built a fully functional app in just a couple of hours. You’ll see the workflow in action—from brainstorming to finished MVP—so you can start building projects faster using the same approach.
