Benchmark leaderboard
Terminal-Bench 2.1 asks a model to complete real engineering work inside a Linux terminal. Artificial Analysis runs every model through the same fixed harness, so the pass rate compares models rather than the vendor agents that dominate the official board. This page lists every model ModelCap tracks with a published AA Terminal-Bench 2.1 result, its best evaluated configuration, the source's own rank, and the model's ModelCap Index position, API price and context window.
Snapshot as of 15 October 2026
Claude Fable 5.1 from Anthropic leads the Terminal-Bench 2.1 (Artificial Analysis run) among the 53 tracked models with 91.4% (Reasoning configuration), per the source snapshot published 15 October 2026.
Sorted by published score, one row per model. Source: Artificial Analysis.
AA Terminal-Bench 2.1 ranks models by Terminal-Bench 2.1 task pass rate on one fixed harness. ModelCap ingests the board as published, matches each entry to a catalogue model with a reviewed identity, and shows the source's score, interval and rank unchanged. AA Terminal-Bench 2.1 is displayed as a public reference board and does not contribute to the ModelCap Index. Its published measurements and tested configurations remain visible here. The methodology page lists the sources admitted to the Index. Read the methodology and identity rules.

Claude Fable 5.1 (Anthropic) holds the top AA Terminal-Bench 2.1 score among the models ModelCap tracks, at 91.4% as of the source snapshot published 15 October 2026.
53 tracked models have a published AA Terminal-Bench 2.1 result on ModelCap; the source board itself lists 128 entries. Each row shows the model's best evaluated configuration.
GLM 5.3 Flash from Z.ai is the highest-scoring model with openly downloadable weights on this board, at 84.3%.
Among the ten highest-scoring priced models, GLM 5.3 Flash has the lowest listed output price at $0.20 per 1M tokens while scoring 84.3%.
The board ranks models by Terminal-Bench 2.1 task pass rate on one fixed harness; higher scores are better. ModelCap shows the source's own score, interval and rank and never re-runs the evaluation.
