Lan(@ad0rnai):We rewrote Prime Agent in Rust with 5x faster cold start, 8x less memory, 2x streaming throughput, and full behavioral parity. Prime Agent is a harness designed from the ground up for long-running agents. The RLM architecture allows many agents to coordinate across a session that outlives any single context window, and is what enabled 2,000+ agents to rewrite the harness they were running on.
