MIT researchers have unveiled a clever new AI framework that flips the script on model size. Instead of relying on one massive model, their system uses a “boss-and-worker” setup where a large planner delegates complex tasks to a team of smaller AI agents—and the results are beating the biggest names in the game.
MIT AI system splits tasks among smaller models for better results
Developed by MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), the system—called DisCIPL (short for Distributional Constraints by Inference Programming with Language Models)—was designed to tackle jobs where precision and rule-following matter more than creativity. Think things like Sudoku, itinerary planning, budgeting, or structured writing.
Here’s how it works:
- A large model plays the role of planner, mapping out how to solve a user’s request
- It assigns parts of the job to smaller follower models, each handling a specific task
- The planner uses LLaMPPL, a custom programming language, to deliver detailed instructions
- If one of the small models goes off course, the boss model steps in to fix the error
This team-based approach has outperformed even GPT-4o in several reasoning-heavy tasks.

In tests involving things like grant writing and grocery list budgeting, DisCIPL wasn’t just accurate—it was lean. The system cut reasoning length by 40% and slashed costs by over 80% compared to some of the largest commercial models, all while matching or exceeding their output.
That’s because each smaller model runs more efficiently, doing focused work under strict guidance. The large planner doesn’t micromanage—it delegates smartly and steps in only when needed.
Why this small model strategy matters for AI’s future
As generative AI continues to balloon in size and compute demands, MIT’s new strategy suggests a different future. Instead of building ever-bigger models, we could coordinate smarter teams of smaller ones—and get better results with lower costs and energy use.
It’s not just an academic proof-of-concept. DisCIPL shows that good planning and clear instructions can make small models punch way above their weight. The giants may still be loudest, but the quiet coordination of smaller minds might just win the long game.
