Rewriting Prime Agent in Rust
The developers of Prime Agent have rewritten their software in Rust to improve performance, reliability, and modularity. The rewrite was facilitated by a swarm of autonomous agents that stress-tested the new infrastructure.
Why it matters
This demonstrates the practical application of AI agents in software engineering and the industry-wide shift toward memory-safe languages like Rust for high-performance AI infrastructure.
Rewriting Prime Agent in Rust Kevin Thomas Sebastian Müller Seth Karten OCT 9TH, 2026 • Research Rewriting Prime Agent in Rust Since we launched Prime Agent [1] in August, it has been downloaded more than 300,000 times and has processed over 8 trillion tokens. Today, we're excited to ship a faster, cleaner and more reliable Prime Agent, rewritten from the ground up in Rust.
Over two weeks, Prime Agent orchestrated a swarm of over 2,000 agents to rewrite itself end to end, operating across 10,000+ Prime Sandboxes with over 200 billion tokens from Prime Inference’s GLM-5.3 endpoint. The Rust rewrite stress-tested Prime Agent’s multi-agent capabilities, including the sandbox and inference infrastructure we’ve been building to power large-scale agent swarms, autonomous research, and reinforcement learning.
