Cosmos3-Nano-Sim-Auto
Distilled causal variant of Cosmos3-Nano-Transfer-Auto, published by NVIDIA on October 20, 2026, for closed-loop driving simulation. It produces synchronized multiview video and LiDAR from controls and text. It supports up to eleven cameras. The ability to respond to controls during a sequence distinguishes it from the bidirectional generator, but it does not constitute an autonomous driving policy.

Interactive simulation with standard and fisheye cameras at 480p or 720p. The declared playback is between 10 and 30 fps; actual inference speed depends on GPU, views, and steps. We do not present the 297 frames and seven cameras from the benchmark as a general product limit nor inherit Transfer-Auto's maximum.
Sim-Auto uses guidance 1 in the recorded results, compared to guidance 3 for Transfer-Auto. Comparisons with Transfer2.5 also use different prompts. Do not mix those configurations nor interpret a single FID value as simulator safety. Review drift, sensor synchronization, and out-of-distribution scenarios before evaluating a driving policy.

Public 16B parameter checkpoint for self-hosted infrastructure. We have not verified a commercial endpoint or token rates: numerical costs are left blank. Downloadable weights do not make inference free. Budget for GPU, memory, video encoding, and operation; review the license of each variant and its dependencies. Playback frames per second do not equate to generation performance.
i Prices change and may depend on level, region or context length. Check the source before making a decision.
05 / EVALUATIONS
How to read the results
“
NVIDIA publishes results in Driving Simulation Evaluation with RGB and LiDAR quality separately. We preserve FID and FVD-I3D for T2V and I2V with guidance 1. The values correspond to this causal variant and improve as they decrease; Transfer-Auto's values are not copied. Inferama's own evaluation and validation in real driving are pending.

Inferama only highlights a “best result” when the metric, test set, configuration, and date allow for an equivalent comparison. The supplier's figures are presented as claims from its own source.
