Credits are used when you chat with Vellum to build and edit your agents. Any time you send a message asking Vellum to create, modify, or reason about an agent, credits are consumed based on the complexity of the request and how much you iterate. Credits are not used when running workflows. Workflow execution is included in every plan. Once your agent is built, you can continue running it without drawing down credits.
No. Today, workflow runtime is included in every plan. We do not charge usage-based fees for running workflows. If this changes in the future, we’ll be clear and explicit about it.
It depends on how complex the agent is and how much you go back and forth in the Vellum chat to refine it. Lightweight agents with little iteration use fewer credits, while more complex agents or workflows you keep improving will use more. Most users start on Free or Pro, then upgrade once they’re building agents they rely on every day.
On the Free plan, you won’t be able to keep editing agents until your credits reset. On Pro and Business, you can buy extra credits as needed or turn on automatic top ups so you can keep building without stopping. On Enterprise, credit bundles and limits are set based on your team’s needs. Your existing workflows will keep running.
No. Credits reset monthly. This keeps pricing predictable while giving you a consistent budget for building and iterating on agents.
A workflow server is the compute that runs your agents. Higher tiers give you larger servers, more workflows running at the same time, and better reliability for production use. As your usage grows, your infrastructure scales with you.
Concurrency is how many workflows can run at the same time. Free is best for testing and early experiments, Pro works well for individual power users, and Business is built for teams that need to run multiple agents in parallel.
Both help with organization, but they do different things. Workspaces separate agents, data, and usage across teams or use cases. Environments control how changes move from development to production. In short, workspaces define who and what the agents are for, while environments define how and when changes go live. Workspaces are available on Business and above, and environments are available on Pro and above.
Data retention is how long Vellum keeps your workflow runs, logs, and related data. This helps with debugging, reviewing past runs, and understanding how agents behave over time. Once data passes your retention window, it’s deleted automatically. Longer retention is especially useful for production agents and regulated teams.
Yes. Many teams start on Free or Pro, then move to Business or Enterprise once agents become critical to their workflows.
Yes. Business supports multiple workspaces for teams and departments, while Enterprise adds onboarding, governance, and custom contracts.
Enterprise plans can include:
- Custom credit bundles and limits
- Custom workflow server sizing
- Dedicated Slack support
- Onboarding and enablement
- DPAs, BAAs, and custom contracts
