Measurement details · 0 successful requests

Successful requests: 0

Model compute is the average per measured request. Delivery time is the median browser time for successful requests, including queue, network, and retries. Cached delivery speed is not inference speed. Model compute can exceed browser time when one request processes many inputs.

Tokens come from response headers. Inference costs use $0.04 per million input tokens, before plan credits. The estimate includes live and recorded tokens at the same rate; cached examples are not charged again. Missing usage is unavailable or a partial total (≥). Demo resets keep these totals; reload to start a new session.

Under the hood How it works & limitations

API calls/classify/rate/yes-no

How it works

Local simulation code predicts conflicts. The model selects an instruction for each aircraft that needs attention, and the simulator applies it while tracking separation and arrivals.

Demo scope

The aircraft and airspace are fictional. Separation rules, physics and traffic are simplified for the demo. The controller can make unsafe choices and is not suitable for real aviation.

Inspired by the work of dabit3.
