LAST MILE Where agents actually land

Preliminary — sweep in progress

Cross-Model Agent Comparison

The same tasks, the same deterministic scoring, three different driving models. The harness decides every outcome — the agent never grades itself — so differences between rows are differences in the models, not in the rules.

Friction Airways (controlled lab)

Last Mile Index by driving model — friction airways (controlled lab)

The same tasks on one mock airline whose readiness profile is the only variable — hostile, median, ready. A model that passes the ready profile but fails real airlines is measuring real-site friction, not its own limits.

Coverage shows how much of the full site×task matrix each model has completed so far; the index is computed only from finished runs and will firm up as coverage completes.

Coverage shows how much of the full site×task matrix each model has completed so far; the index is computed only from finished runs and will firm up as coverage completes.

Method

Same rules for every model.

Each run record carries the driving model as provenance. Outcomes are decided by deterministic probes and a verified success check — pass, fail, or blocked at an honest access wall (blocked runs are excluded from the measurable index). Partial coverage means partial confidence: treat gaps between models as directional until the sweep completes.
