Terminal Bench
Terminal-Bench 2.0 · evaluates AI agents on real terminal-based coding tasks · writing scripts, debugging, running tests, and managing projects entirely through command-line interaction. Tests both code quality and terminal fluency. Claude Opus 4.7 scores 69.4%, demonstrating significant agentic terminal competence.
Tests both code quality AND terminal fluency. Opus 4.7 scores 69.4%.
Scoring: Task completion rate based on filesystem state comparison. The model's terminal session produces a final state that is diff-checked against the expected output.

How it works
Evaluation methodology
Terminal-Bench 2.0 evaluates AI agents on real terminal-based coding tasks that must be completed entirely through command-line interaction. Tasks include writing scripts, debugging existing code, running and interpreting test suites, managing git repositories, and orchestrating multi-file projects. Models interact with a real shell environment and are evaluated on whether the final state of the filesystem matches the expected output. Tasks cover Python, JavaScript, Bash, and system administration.
Industry relevance
Why teams track this benchmark
Terminal-Bench directly measures the capability that powers AI coding assistants like Claude Code, Cursor, and Windsurf. A model's Terminal-Bench score predicts how well it will perform as an interactive coding partner. This is the benchmark developers care about most.
Practical takeaways
By role
Terminal-Bench scores directly predict AI coding assistant quality. If evaluating models for a coding product, this is your primary benchmark.
Terminal-Bench leaders capture the developer tools market. GPT-5.4 at 75.1% and Mythos at 82.0% are the current production-ready tier.
The multi-step nature of terminal tasks makes this ideal for studying planning and error recovery in coding agents.
