| # AlpaSim Challenge 2026 |
|
|
| This Docker Space serves a static landing page with an embedded Gradio app for: |
|
|
| - team registration |
| - signed-in participant registration status |
| - public PAI and nuPlan leaderboards |
| - a reviewer-only `Review` tab for approving or rejecting pending registrations |
|
|
| Participants connect their Hugging Face account from the registration page. The |
| Space uses the signed-in Hugging Face profile to capture the captain username, |
| stable Hugging Face `sub`, and email when available. |
|
|
| The Space must define these secrets: |
|
|
| ```text |
| ALPASIM_API_BASE_URL |
| ALPASIM_REGISTRATION_SECRET |
| ``` |
|
|
| For the AWS H100 prototype, `ALPASIM_API_BASE_URL` should point at the |
| `us-east-1` API Gateway endpoint, for example: |
|
|
| ```text |
| https://<api-id>.execute-api.us-east-1.amazonaws.com |
| ``` |
|
|
| Do not commit the registration secret to this repository. |
|
|
| ## Tabs |
|
|
| `Registration` lets a signed-in captain submit a team request. Optional fields: |
| additional submitter Hugging Face usernames, credited contributors, organization, |
| country/region, and notes. The form is hidden once the signed-in captain has a |
| pending, approved, or registered team. After approval, listed additional |
| submitters can connect Hugging Face in this tab and click `Join Team` to bind |
| their stable Hugging Face `sub` to the approved team. |
|
|
| `PAI Leaderboard` and `nuPlan Leaderboard` load public leaderboard data from |
| the backend. |
|
|
| `Review` is hidden unless the signed-in Hugging Face user's stable `sub` exists |
| as an active `reviewer` or `admin` in the `alpasim-reviewers` DynamoDB table. It |
| lists registrations by status, shows full registration details, and supports |
| approve/reject actions. Approval grants captain access and leaves any additional |
| submitter usernames as claimable post-approval invitations. |
|
|
| ## Documentation |
|
|
| Capability score computation is documented at: |
|
|
| ```text |
| https://ln2697.github.io/navhard-leaderboard-2/docs/ |
| ``` |
|
|
| ## Soft Open Notes |
|
|
| The nuPlan track currently uses a provisional dataset. Teams may submit during |
| this period to validate the workflow and understand the evaluation process. When |
| the updated nuPlan data is available, organizers will clear the nuPlan |
| leaderboard and resubmit each team's best submission. |
|
|
| The PAI track currently includes a subset of the final scenes. Additional scenes |
| will be added later in the competition. |
|
|
| Bugs, questions, and competition discussions should be raised on the public |
| AlpaSim repository: |
|
|
| ```text |
| https://github.com/NVlabs/alpasim |
| ``` |
|
|
| ## Prizes |
|
|
| Each track will award two NVIDIA DGX prizes: |
|
|
| - PAI-AV track: two NVIDIA DGX prizes for the top two teams. |
| - nuPlan track: two NVIDIA DGX prizes for the top two teams. |
|
|
| The app serves the landing page from FastAPI at `/` and mounts Gradio at |
| `/gradio`. |
