[New Video] Which model should you use in your AI Agents? DeepSeek‑r1, o3‑mini & Gemini Flash 2.0

Hey everyone!

The AI world is moving FAST—Google just dropped Gemini Flash 2.0, OpenAI released O3 Mini, and DeepSeek-R1 is making waves. So I had to put these models to the ultimate AI agent test.

I ran all of them inside CrewAI to answer one simple question:

Which AI model is best for AI agents?

In this video, I break down:

✅ Instruction following – Can they handle complex, rule-heavy prompts?

✅ Tool calling – Do they execute multi-step processes efficiently?

✅ RAG performance – Which model retrieves and processes large datasets best?

✅ Final verdict – Which model should YOU be using for AI agents?

Some models surprised me, while others fell behind. Watch the breakdown to see the results!

I’m curious—which model do you think performs best for AI agents? Drop your thoughts in the comments!

Cheers,

Brandon 🧑‍💻
