Per-end-user fair use — stops a few users from burning through your quota: every end user gets a monthly base allowance, and overages follow the policy you choose
MAU definition: an external_user_id only counts if it had ≥1 session that month — inactive users are never billed; session-level rate limits prevent single-user abuse.
Usage pricing — all consumption converts to credits (numbers are illustrative)
| Billable item | Unit | Credits | Underlying cost |
|---|---|---|---|
| Chat · standard models | per 1K tokens | 1 credit | LLM calls |
| Chat · Pro models | per 1K tokens | 5 credits | LLM calls |
| Speech synthesis (TTS) | per 1K characters | 2 credits | Audio |
| Realtime voice calls | per minute | 10 credits | Audio |
| Additional end users (beyond plan MAU) | per user · month | 20 credits | Memory storage + embeddings + retrieval |
| Knowledge-base storage | per GB · month | 50 credits | Memory storage |
Why we bill this way — how the three cost drivers price in
1 End-user count (MAU) is the only hard gate Projects and agents are just configuration with near-zero cost, so they're unlimited; memory (storage, embeddings, retrieval) scales with users, so it's bundled into MAU — user count is cost count, and it's the easiest number for customers to forecast.
2 LLM calls → per token The largest variable cost, with different credit multipliers per model tier; developers can pick standard or Pro models per agent to control spend.
3 Audio → per character / minute Speech synthesis bills per thousand characters, realtime calls per minute. Everything else (A2A, instant generation) costs little and is absorbed into the base price rather than billed separately.
