By 2026, building AI systems is no longer just about choosing the “best” model.
What actually matters is how you combine models, frameworks, and infrastructure into a stack that can handle real-world constraints like cost, latency, and reliability.
Some patterns we’re seeing more often:
- Smaller, efficient models (like Mistral or Phi) handling fast, low-cost tasks
- Larger models reserved for complex reasoning or edge cases
- Orchestration and reasoning frameworks (such as LangGraph or AutoGen) coordinating how everything works together
We recently shared a short video breaking this down visually for those who prefer quick, bite-sized content:

The main takeaway: modern AI stacks are becoming modular by design. Teams that think in terms of systems, not single models are the ones shipping faster and more reliably.
