Data modelling and DAX
Different models are better at different jobs. Use a premium reasoning model for planning and design. Once the plan is locked, switch to a faster, cheaper model to execute it. Stop sending the senior partner to file the paperwork.
A good assistant doesn’t do everything themselves. They send the intern. Subagents are read-only sub-chats your main chat spawns to do the heavy reading and report back. Your conversation keeps its memory.
Don’t run AI models in parallel. Chain them in series, across vendors. The output of one becomes the input to a critique from another. Different training data means different blind spots.
