Pay attention to the prices and what a combination of models can unlock for you.
You don't need the absolute best model for everything.
I am not that impressed with the Rust SQLite replica. A totally new and improved SQLite （or something more creative and new） could be a more interesting test.
Takeaways：
- Use a frontier model for decomposition， architecture， key design choices， and trade-offs.
- Have cheaper， faster workers execute well-defined， narrow implementation tasks.
- Do not have planners implement or workers make broad design decisions.
Use a swarm or harness with a recursive task tree： planners break the original spec into subtrees， delegate them， and workers operate at the leaves. Cursor argues this helps mostly because each agent has a constrained context， rather than simply because many agents run in parallel. Pay extra attention to biases and failures that might emerge from poor/inefficient agent coordination.
We had a team of agents rebuild SQLite from its 835-page manual. It created a replica in Rust which passed 100% of a held-out test suite. Interestingly, cost va...
