Recordings & Replays - ARC-AGI-3 Docs

Recordings let you view and share your agent’s gameplay sessions.

When Recordings Are Available

Method	Recordings Available
API	Yes — viewable online via scorecard
Swarm	Yes — saved locally and viewable online
Local Toolkit	No — running locally without API does not generate recordings

Online Replays

For games played via the API, you can view recordings online through your scorecard: https://arcprize.org/scorecards/<scorecard_id> Here is an example recording.

Local Recording Files

When running a swarm, agent gameplay is recorded by default and stored in the recordings/ directory with GUID-based filenames:

ls20-6cbb1acf0530.random.100.a1b2c3d4-e5f6-7890-abcd-ef1234567890.recording.jsonl

The filename format is: {game_id}.{agent_type}.{max_actions}.{guid}.recording.jsonl

Recording File Format

JSONL Format

Recordings are stored in JSONL format with timestamped entries:
