How credits are consumed
Credits are deducted in real time as you interact with your Digital Twin. The core unit is the token — Pria converts every model’s reported token usage into credits using a published per-model rate, and meters non-text actions (images, video, voice) separately.Token-to-credit conversion
The exact per-million-token rates vary by model and update with provider pricing. The full live table is visible under Your Profile → Billing.
Non-text actions — metered separately
At-a-glance cost table
The rough relative costs (lowest → highest) for common actions:Star ratings are relative — they convey order of magnitude, not exact rates. See Your Profile → Billing for current dollar/credit amounts.
Where credits live — Account, Institution, User
Pria’s credit pool is hierarchical: credits sit at one (or more) of three levels, and each conversation draws from the lowest level that has a positive balance.
Draw order: User credits → Institution credits → Account credits. If your user balance is positive it depletes first; once empty, conversations fall through to the institution pool, then the account pool.
For per-twin allocation, low-balance alerts, auto top-up rules, and the admin’s view of the credit hierarchy, see the Credit Management admin guide.
Low-balance behaviour
Pria tries hard to warn you before credits run out so you’re never mid-conversation when the lights go off.Alerts
- Low-balance banner appears at the top of the interface when the active credit pool drops below a configurable threshold (default 10% of the typical 7-day spend). Admins set the threshold under Credit Management.
- Email notification to billing contacts when an alert threshold trips, so the right people see it even if they aren’t currently signed in.
- Per-twin status chip on the sidebar — the credit balance icon turns amber under 10% and red at 0.
Auto top-up (if enabled)
Admins can enable auto top-up at the Account or Institution level: when the pool falls below a configured floor, Pria automatically purchases a top-up against the stored payment method. The new credits land before the pool depletes, so conversations never interrupt. Auto top-up is off by default — turn it on under Credit Management → Auto top-up. The maximum top-up frequency and cap are set there too, so you can’t accidentally drain a payment card.When credits hit zero
If the pool runs out and no auto top-up is configured:- In-flight conversation — the running response finishes (Pria doesn’t cut you off mid-sentence), but the next prompt is blocked.
- New prompts show a clear “Your Digital Twin is out of credits” dialog with a direct Add Credits button (users) or instruction to contact your admin (institution-funded users).
- File uploads, image generation, voice all fail with the same dialog rather than producing partial output.
- Read-only features (browsing past conversations, searching the vault, viewing files) continue to work — you only lose the ability to spend new credits.
Optimization tips
Most Digital Twins use 3–5× fewer credits with a small handful of habits. See Credits Optimization for the full guide; the short version:- Lower Remember History when long context isn’t needed (quick lookups don’t need 10 turns of history).
- Tune your retrieval mode — Disabled or RAG Only is cheaper than RAG + KAG Fusion; pick the right mode for the question.
- Skip Indexing on URL imports you only want to download, not embed.
- Prefer text over Convo Mode for fact lookups — voice is convenient but more expensive per turn.
- Use Skip Indexing for files you only need to store and open yourself (not search) — they skip the knowledge-processing pipeline entirely, so they cost nothing to index.
- Sanitize noisy segments so they’re shorter to embed and retrieve.
- Avoid HD image gen unless you need print-grade output.
