LHTB Solved

LHTB Solved is a benchmark for how well a model works as an autonomous coding agent. The official description says: "Long-Horizon-Terminal-Bench (LHTB) Solved metric from IntelligenceLab". Below we describe in simple words what benchmarks of this type generally examine.

LHTB Solved measures how well a model works as an autonomous coding agent. In detail, it checks:

• fixing real, open bugs from real software repositories
• planning multi-step changes, running commands and editing files by itself
• passing the project's test suite after its changes
• handling whole repositories, not just small isolated code snippets

The score is accuracy: the percentage of tasks answered or solved correctly. 100% means every task was solved perfectly; higher is better.

Official methodology note: Long-Horizon-Terminal-Bench (LHTB) Solved metric from IntelligenceLab. Evaluates long-horizon terminal-based agentic tasks.
