OpenBlock just secured #2 on Terminal Bench with our frontier coding agent, OB-1.

Our result illustrates how specialized agents built by small teams can outperform the monolithic systems of big labs.

We built OB-1 to mimic how a capable engineer works: – Persistent memory blocks to track goals, todos, and notes – Adaptive timeouts that keep the agent moving – Editable reasoning so it can revise and self-correct – Direct terminal execution to finish tasks cleanly
