Concurrency
LiveHow many generation Runs your account can process at once.
What concurrency means
The concurrency cap is the maximum number of generation Runs that can process at the same time on your account. Each plan gets its own cap, and it goes up as you move to a higher tier. It is a separate question from how many products one bulk batch may cover — that is a batch-size limit, and asking for more results from the same inputs is a concurrency question, not a bulk one.
Your plan’s cap
Your account’s cap is shown in Billing, alongside the rest of your plan’s limits, and each plan states what it includes on pricing. Read it there rather than assuming a fixed number — caps are tuned as capacity changes, and the figure on your account is the one that binds.
When you hit the cap
When you’re at your cap, new Runs don’t fail — they queue. Each queued Run starts automatically as a slot frees up, so you can keep launching work and let Mocart drain the queue in order.
