AlpaSim E2E Challenge 2026 — NuPlan / MTGS Track Data
This dataset contains the official evaluation assets for the NuPlan / MTGS Track of the AlpaSim E2E Closed-Loop Challenge 2026.
These resources are managed exclusively by the trusted evaluator. Contestants do not need to package or depend on them in their submitted driver images.

MTGS_asset/navtest/
Neural rendering assets used by the MTGS renderer during closed-loop evaluation. The evaluator mounts these assets into the simulator stack; contestant containers do not have direct access to them.
trajdata_cache/nuplan_test.tar.gz
Pre-built trajdata cache for the nuPlan test split. The evaluator uses this cache to initialize and drive nuPlan scenes during evaluation rollouts.
How Evaluation Works
- The evaluator starts the full AlpaSim simulator stack (physics, traffic, MTGS renderer) using the assets in this dataset.
- The contestant's driver container receives rendered camera images and scene state over gRPC and must respond with control commands within 0.1 s per
Drivecall. - Results are aggregated and posted to the leaderboard.
The official evaluation preset is +e2e_challenge=ec2 (topology=8gpu_36rollouts): 12 contestant replicas across GPUs 4–7, each handling 3 concurrent rollouts.
Contestant Submission Requirements
- Implement
egodriver.EgodriverService(seesrc/grpc/alpasim_grpc/v0/egodriver.proto). - Image size ≤ 40 GiB; do not bundle nuPlan data, trajdata caches, navtest configs, or MTGS assets.
- Outbound network access is blocked during evaluation; the root filesystem is read-only.
- Writable scratch space:
/tmp(2 GiB),/run(64 MiB).
