New AI models just dropped, but which one is best for AI agents? I tested O3 Mini, Gemini Flash 2.0, and DeepSeek-R1 inside CrewAI against Claude 3.5 & GPT-4o to find out.
We put them through three real-world tests inside CrewAI:
Instruction Overload – Can they follow complex, rule-heavy prompts?
Tool Calling Challenge – How well do they handle multi-step tool calls?
Needle in a Haystack (RAG Test) – Which model retrieves and processes massive data best?
Some models performed surprisingly well, while others struggled. Watch the breakdown to see the results!
