LLM Cost (OpenRouter) - ONA.UNO Docs
ONA.UNO uses OpenRouter to access cloud AI models. This page provides real-world cost estimates based on actual usage.
Costs vary based on content length, model selection, and usage patterns. Use these figures as a guide, not a guarantee.
Initial Library Processing
When you first add sources to ONA.UNO in Online mode, every item needs:
- Embeddings — mathematical vectors for semantic search
- Summaries — bullet-point overviews
- Titles — descriptive names
- Tags — conceptual labels
This initial processing is the largest one-time cost.
| Library Size | Estimated Cost | Processing Time |
|---|---|---|
| 1,000 items | $0.30–0.40 | A few minutes |
| 10,000 items | $3–4 | ~10 minutes |
| 25,000 items | $8–10 | 20–30 minutes |
Processing time depends on OpenRouter’s current load and your content complexity.
Ongoing Costs
After initial processing, you only pay for new content and interactive features.
New Items
When new notes, emails, or clips arrive, ONA.UNO processes them automatically.
| Volume | Estimated Cost |
|---|---|
| 100 new items | $0.04–0.06 |
| 1,000 new items | $0.40–0.60 |
Chat Conversations
Chat costs depend on conversation length and which model you use.
| Usage | Estimated Cost |
|---|---|
| Short conversation (a few exchanges) | $0.01–0.03 |
| Long conversation (many back-and-forth exchanges) | $0.05–0.15 |
Full Summaries
Full summaries aggregate content across multiple items.
| Usage | Estimated Cost |
|---|---|
| Single full summary | $0.003–0.006 |
| Daily summary habit (365 days) | $1–2 per year |
Monthly Estimates
Here’s what typical usage patterns cost:
| Usage Pattern | Estimated Monthly Cost |
|---|---|
| Light (few new items, occasional chat) | $0.50–1 |
| Moderate (30–50 new items/day, regular chat) | $2–5 |
| Heavy (100+ new items/day, frequent chat and summaries) | $5–10 |
Cost Control
You’re never at risk of surprise bills:
- Set a spending limit on your API key in OpenRouter’s dashboard
- Monitor spending in ONA.UNO’s status bar (current month + last request)
- Set Credits to not top-up automatically — when they run out, requests simply stop
