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!

Makers residency 4th edition

Your idea can be anything. At our last workshops, people built plant-based nutrition businesses, a way to measure planetary resilience, crochet headwear and a way to connect lonely people living in the same building. An asset manager went on to raise an additional Β£25M on their fund within nine months. The fourth workshop is a full day at KOKO with Nick Sarafa, learning to build with Claude Code. Bring the thing you keep meaning to start. We’ll bring the pizza.
