Summary
Experiments with agent swarms demonstrated the potential for cooperative task execution at larger scales and complexities. A flagship project involved a swarm successfully building a web browser from scratch, serving as a proof of concept despite not achieving polished software.
Key Takeaways
- The new agent swarm model successfully built SQLite from scratch in Rust, achieving 80% test suite pass rate in four hours, outperforming the previous swarm model.
- The agent swarm design features planner agents that delegate tasks and worker agents that execute them, allowing for efficient context management and task decomposition.
- The new system can handle approximately 1,000 commits per second, significantly increasing the volume of work compared to earlier models that peaked at 1,000 commits per hour.
- The efficiency of the agent swarm is attributed to its context management, allowing it to scale effectively across various tasks without losing sight of the overall goal.

Positives
- The rapid increase from 1,000 commits per hour to 1,000 commits per second shows a major leap in swarm efficiency, hinting at a new era for collaborative AI models.
- There's excitement around the innovative experiments happening, even if they aren't perfect yet — it's all part of the journey towards more capable coding agents.
Concerns
- Concerns about LLM memorization of training sets raise questions about the true originality of these models — are we just recycling existing code?
- The complexity of building a new version control system just to support the swarms seems excessive, leading some to wonder if this is over-engineering.
