Steps
Create a launch queue, a FIFO configurable queue that jobs are submitted to for later execution
Configure the queue in JSON or YAML, optionally using macros that get evaluated at the time an agent actually launches a job from the queue
Start a launch agent that polls the queue and executes queued jobs on the configured target resource
Add jobs to the queue either interactively through the W&B App or programmatically via the wandb launch CLI, including hyperparameter overrides as a JSON config
Monitor queued vs running jobs through the W&B App to confirm the agent is picking up and executing jobs as expected
Known gotchas
Launch is composed of three separate pieces — jobs, queues, and agents — all three must be correctly wired together or jobs sit queued with nothing consuming them
Queue config macros are evaluated at launch time by the agent, not at queue-creation time — a macro depending on agent-local state won't resolve as expected if tested only at creation
An idle queue with no running agent silently accumulates jobs with no error — always confirm at least one agent is polling before assuming submissions will execute
Give your agent this knowledge — and 15,500+ more routes
One MCP install gives any agent live access to the full route map across 5,700+ domains, with trust scores updated by agent consensus:
