Terminal-Bench 3.0
We mirror this table; we do not rank on it.
A continuously maintained benchmark for difficult computer work, including coding, deep learning, finance, engineering, math, and science tasks.
Current release
Terminal-Bench 4.0 is the current release. It recalibrates task resources, fixes 19 tasks, and removes eight, so its scores are not directly comparable with Terminal-Bench 3.0.

We mirror the published tasks completed view for Terminal-Bench 3.0. Claude Opus 5 leads the public snapshot at 42.7%, followed by GPT-5.6 Sol (34.6%) and Claude Fable 5 (34.0%). We do not weight the raw table directly. A normalized version can contribute through our external agentic consensus gate.

ScoreHow we use Terminal-Bench 3.0
We mirror the Terminal-Bench 3.0 version 3.0 table: 74 professional computer-work tasks across 7 domains. The Terminal-Bench and Harbor team first released this benchmark under the FrontierBench name.
Each row measures a model and agent harness together, including Codex, Claude Code, mini-SWE-agent, or Cursor CLI. We therefore keep the raw table display-only. The normalized result counts as one external agentic benchmark family, and the ranking pipeline requires another benchmark family and evaluator before it can affect a model score.
Snapshot
The published Terminal-Bench 3.0 snapshot places Claude Opus 5 first at 42.7%. The third row is 8.7 points behind. The broader top-10 range is 28.1 points, so the table still separates the published systems.
12 models have been evaluated on Terminal-Bench 3.0. The benchmark falls in the Agentic category. This category carries a 22% weight in BenchLM.ai's overall scoring system. Terminal-Bench 3.0 is currently displayed for reference but excluded from the scoring formula, so it does not directly affect overall rankings.

Frontier autonomous knowledge work
Terminal-Bench 3.0, formerly FrontierBench, launched as version 0.1 with 74 tasks across seven domains. Each public row combines a model with an agent harness, so we keep the raw results display-only. Its normalized score counts as one external agentic benchmark family and cannot make a category eligible without independent corroboration.

Public benchmark set
BenchLM uses freshness metadata to decide whether a benchmark should still be treated as a strong differentiator, a benchmark to watch, or a display-only reference. For the full scoring policy, see the BenchLM methodology page.
Questions
What does Terminal-Bench 3.0 measure?
A continuously maintained benchmark for difficult computer work, including coding, deep learning, finance, engineering, math, and science tasks.
Which model leads the published Terminal-Bench 3.0 snapshot?
Claude Opus 5 currently leads the published Terminal-Bench 3.0 snapshot with 42.7% tasks completed. BenchLM keeps the raw table display-only. A normalized version can contribute through the external agentic consensus gate, which still requires independent corroboration.
How many models are evaluated on Terminal-Bench 3.0?
The September 18, 2026 snapshot snapshot contains 12 AI models.
