AI agent glossary for reading a price page
IC Guides · AI Agents · Start here
Price pages for AI agents use words that sound alike and mean different things. This glossary covers the ones that decide your bill. Each links to the live examples in the AI Agent Pricing Tracker.
- Seat
- A fixed price per user. Predictable, but you pay for people who barely use it.
- Outcome
- A result the vendor defines and bills for, such as a resolved ticket. The definition is the vendor’s.
- Resolution
- An outcome in support, where the agent closes a conversation. Vendors differ on what counts, including whether silence counts.
- Conversation or session
- One exchange with a customer. Billed whether or not it solved the problem.
- Credit
- A prepaid unit of capacity. Different actions use different amounts, so credits are not tasks.
- Token
- A chunk of text a model reads or writes. Developer platforms bill by tokens, and agents use many per task.
- Execution
- One run of a workflow. Some tools bill per execution, others per step inside it.
- Module
- One step in a workflow. On some tools every module is a billable unit.
- Hosting minute
- A minute of voice agent runtime. Often excludes the model, voice and phone line.
- Escalation
- The agent hands the case to a human. Whether that is billed varies by vendor.
- Hybrid pricing
- A platform fee plus usage. Most enterprise deals end up here.
- Overage
- Usage beyond your plan. It may be billed at a higher rate or blocked.
- Commitment
- A volume you agree to pay for in advance, usually for a lower rate.
- Concurrency
- How many calls or runs can happen at the same time. Sometimes priced separately. Retell includes 20 concurrent calls free and charges $8 a line a month beyond that; Vapi includes 4 and charges $10 a line.
- Cached input
- Input tokens the provider has seen recently and bills at a lower rate. On OpenAI’s gpt-6.1-sol, cached input is $0.10 per million against $2.00 for fresh input.
- Orchestration fee
- A percentage charged on top of credits by some builder platforms. Gumloop lists 8% on Pro.
- Pooled credits
- Credits shared across a workspace rather than owned by one seat. One heavy user can draw down the team’s allowance. Lindy pools 5,000 per seat.
- Excessive agency
- OWASP’s term for an agent given too many tools, too many permissions or too much autonomy, so that a wrong or manipulated output causes damage. See permissions and safety.
- Workflow versus agent
- Anthropic’s distinction is that a workflow follows predefined code paths with model calls inside, while an agent lets the model direct its steps and tool use.
Read next Which AI agent, and what it really costs.
One workload, different meters
Imagine 1,000 customer requests in a month. Suppose each request triggers one conversation, five workflow module actions and one full workflow run, and 700 requests are resolved. These are illustrative assumptions, not vendor prices.
| Billing unit | Usage counted in this example | What to verify |
|---|---|---|
| Conversation | 1,000 conversations | When a conversation starts and resets |
| Resolution or outcome | 700 successful outcomes, if all qualify | What counts as success and whether reopened cases are charged |
| Execution | 1,000 workflow runs | Whether retries count as additional runs |
| Module action | 5,000 actions | Which modules consume billable units |
| Credit or token | Cannot be determined from request count alone | Rates per action, model usage and context length |
This is why two vendors with the same advertised unit price can produce different invoices. Map the work to the billable event first, then multiply by the published rate and add fixed fees.
Apply these terms See how action credits compare in Copilot Studio vs Agentforce, how workflow steps affect charges in n8n vs Make, and how outcomes differ from quotes in Fin vs Ada.
